Thank A Penis

NPR published a brief, blurby-type article about “Naked Attraction,” a dating game show streaming on HBO, acquired from England’s Channel 4, the publicly-owned, commercially-operated English broadcaster separate from the BBC, which is paid for by commercials. Apparently, the show’s quite popular, and for whatever reason, has created quite a stir here in the States.

As you might suspect, Naked Attraction is yet another naked pseudo “reality” type show in which the contestants participate unclothed, which, as Neda Ulaby, who reports on arts, entertainment, and cultural trends for NPR’s Arts Desk, wrote, has a fairly simple concept. “Here’s the gimmick: One contestant faces six boxes that contain six naked people. Bit by bit, their bodies are revealed, starting from the bottom. The contestant eliminates possible future dating partners based on the body parts they see.”

Professor Dr. Jeffrey P. Jones, PhD, Executive Director, George Foster Peabody Awards, and Professor at the University of Georgia, authored a book on HBO’s history, was interviewed for the article and stated the most likely reason for the show’s newfound attention:

“They are showing full male frontal nudity, and that’s maybe what’s catching a few breaths. This is marketing that happens without the HBO or Netflix marketing departments.”

In the article, Ms. Ulaby asked a blasé question: “But if nudity is a gimmick that gets them — what happens when nudity gets old?”

Professor Dr. Jones, who earned his undergrad & master’s at Auburn, and PhD at UT Austin, had a succinct reply for that:

“People will never get tired of nudity. It’s on frescoes all through Europe. Nudity is with us forever. Frankly, it’s a central part of who and what we are as humans, and we’re going to tell stories about it.”

On a personal level, I’m glad to know, that at least in a minor way, American society is finally, slowly acknowledging that men have penises, since we so rarely see them in film, or television. That fact seems to have escaped our Puritanical Evangelical brethren who eschew acknowledging that foundational core value of our being, which is that we all owe our existence to a penis.

And to be fair, there’s necessity in the ovaries & fallopian tubes, (manufacturing & delivery), vagina (sometimes termed “introitus,” or driveway) and, uterus (the housing center), as well.

But we in America have shamed the human body, have instilled via extreme, fear-based, punishment-exacting religious indoctrination, a base of shame-based guilt, for no good reason, save to perpetuate a system of dogmatic indoctrination, and legal articulation of extreme rightwing radical religious rhetoric.

It is unimaginable that in this year, era, and age, that

Yes, there TRULY IS good science behind medical marijuana!

And, here’s an example.

Recently, in the course of my reading (and I read EXTENSIVELY), I happened upon a brief excerpt from a recently-published book — it was a summary of a chapter from a recently-published healthcare-science text entitled “Medicinal Usage of Cannabis and Cannabinoids,” edited by: Victor R. Preedy, Vinood B. Patel, and Colin R. Martin.

The authors are respected in their fields, all possess terminal degrees, and their biographies are impressive.

Are You A Fan Of Bacon? You’ll Want To Read This.

Bacon is not my thing, per se, at least insofar as, once you’ve had the AUTHENTIC product, it’s difficult to return to the imposter.

By AUTHENTIC, I mean to refer to what some folks call “slab” bacon, which is smoked, and dried, so that the uncooked slab of bacon needs NO REFRIGERATION, and is often found hanging in the open in the grocer’s meat section.

This product is what some call “streaky bacon,” which is what the English call this type of American-produced bacon.

Now, remember… before refrigeration came along, the preservation of meats was done primarily by smoking, and curing — and THAT was a technique learnt from the Native Americans in the earliest days of American history, i.e., by the colonists at Jamestown, Plymouth, etc.

That is also why, when the first enduring “snap” of winter, i.e., COLD weather, came along, it was called “hog killing weather,” because the cool, even cold temperatures largely delayed (retarded), if not temporarily prevented, spoilage (as rancidness, referring to an oxidized, deteriorated state of fat), and deterioration (rotting) of the uncooked flesh. Lard would be rendered (changed in character) from fat, which is accomplished by heating it, most typically in a large cauldron suspended over an open fire, to melt it.

EVERY PART of the hog would be used, which how the phrase “everything but the squeal” originated. The fat, the jowl, the hock, the ham, the loin, the back strap, the trotters (feet), the ears, the liver, the heart, stomach, snout, skin, and even the intestines (chitlins, or chitterlings), were ALL used as some sort of food item.

Nowadays, the meat is processed wham-bam-thank-you-ma’am with numerous godforsaken chemicals, soaked in brine, injected with water and chemicals that make it soak up water (that’s bordering on fraud, to pump water into meat, or use chemicals to cause it to absorb water to increase its weight), injected with preservatives, nitrates (often as celery powder), nitrites (agents that interact with the hemoglobin naturally present in pork (blood in the flesh) that cause it to have an unnaturally red, or pink appearance and which eventually become nitrosamines, known carcinogenic compounds causative of stomach, bladder, colorectal, and breast cancers, vacuum packed, thrown in a refrigerator, and rushed to market.

Just read the labels sometimes, and look up things like sodium erythorbate (an anti-oxidant, color fixative, cure accelerator and synthetic variation of ascorbic acid, aka vitamin C), sodium phosphate — used to help meat retain moisture, and prevent development of rancid odor from the fat (which is deteriorating, or else it wouldn’t be added), HFCS (high fructose corn syrup) which is metabolized differently than sucrose (table sugar) and known to cause weight gain and Type II diabetes, sodium tripolyphosphate (STPP) which is an inorganic hydrophilic (attracts & retains water) emulsifier, and is even used in detergents, etc.

When cooked or broken down in the stomach, nitrites form nitrosamines (aka N-Nitroso Compound), which are known carcinogens, particularly among young children and pregnant women.

The USDA limits addition of nitrites (as sodium nitrite) in food to 200 parts per million. The thinking, or hope, is, that by adding ascorbic acid (aka sodium erythorbate, the synthetic form of vitamin C) to the processed food, it allegedly reduces formation of nitrosamines, though there is no conclusive scientific evidence proving it.

The addition of sodium nitrate is limited, whereas the addition of celery powder is unlimited, and is considered “organic.” Neither celery powder nor celery salt is regulated by the USDA, but chemically processed sodium nitrate is.

Nitrate residue on processed foods using “natural” sources of nitrates (such as celery powder), is often at least 10 times HIGHER than that found on traditionally cured products.‌

Essentially, it’s a bait-and-switch shell game — a culinary con game, and the consumer is the mark.

But to add insult to injury, today’s hogs are NOT

UK Researchers Find Cannabis Abstainers LESS Motivated Than Cannabis Consumers

—>This is NOT A JOKE!<—

Ms Martine Skumlien is a PhD student in the Department of Psychiatry, University of Cambridge, United Kingdom. Her research centers around the impact of regular cannabis use on brain and cognition, with a particular emphasis on use in adolescence, in which she utilizes behavioral data along with fMRI in her work.

Ms. Martine Skumlien, MRes, is a researcher affiliated with the Department of Psychiatry, University of Cambridge, Cambridge, UK -and- Clinical Psychopharmacology Unit, Clinical Educational and Health Psychology Department, University College London, London, UK, and was lead researcher of a team of 16 that recently published their findings in the 14 August 2022 edition of the peer-reviewed International Journal of Neuropsychopharmacology.

In the research entitled “Anhedonia, apathy, pleasure, and effort-based decision-making in adult and adolescent cannabis users and controls,” [also at: International Journal of Neuropsychopharmacology, pyac056, https://doi.org/10.1093/ijnp/pyac056] the results showed that non-cannabis users “had higher levels of anhedonia than cannabis users.” Anhedonia is the clinical term referring to the inability to feel or experience pleasure.

In their conclusion, the researchers wrote, “Our results suggest that cannabis use at a frequency of three to four days per week is not associated with

Evangelicalism Poisons Christians’ Pool

The late, renown musician Greg Allman, with his Southern Rock group “The Allman Brothers Band,” recorded and performed a song entitled “Angeline,” which was written by band members Dickey Betts, Mike Lawler, and John Andrew Cobb. Greg had no part in the song’s creation, other than to sing, and record it, where is appears as Track 1, Side 2 (Track 5 on CD) of the band’s first Arista Records, Inc. label release, on their August 1980 album “Reach for the Sky.”

The song’s chorus contains the partial lyric “I never seen a woman who could look so good, and be so doggone mean. Yeah.”

I had forgotten the song’s title was Angeline, rather than Evangeline, but the point is, that the name “Evangeline” is a feminine one, and in a couple places in the New Testament, and in modernity, the “church” is frequently referred to as a feminine subject, a “virgin bride” which will “marry” Jesus Christ. And, I had not forgotten the song’s lyric “I never seen a woman who could look so good, and be so doggone mean.” 

That is a sadly perfect picture of the church today: Alleged to be beautiful (“a woman who could look so good,”) but whose attractiveness is marred to the point of repulsion, i.e., “be so doggone mean.”

The song’s final verse is:

Whoa, just a game that she loves to play,
leavin’ broken hearts all along the way.
She’s got friends that she ain’t never used.
She’s winnin’ now but she’s bound to lose.
Oh, Angeline.

Again, a picture perfect illustration of a very sad situation: Selfish use and abuse, then, abandonment, and ultimately, loss.

What many folks don’t realize (and, by “folks,” I specifically mean to refer to those who name Christ, or claim to be Christian), that many of the researchers and historical figures of importance in the history of healthcare and immunology were Christians.

Edward Jenner (1749-1823), considered widely as the “father,” or discoverer of vaccination, was himself a son of a Christian vicar, the 4th son, and 8th of 9 children, whose both parents died in 1754. But what is equally ironic, is that in his era, when he was actively developing a treatment and cure for smallpox, “Jenner was widely ridiculed. Critics, especially the clergy, claimed it was repulsive and ungodly to inoculate someone with material from a diseased animal. A satirical cartoon of 1802 showed people who had been vaccinated sprouting cow’s heads. But the obvious advantages of vaccination and the protection it provided won out, and vaccination soon became widespread. Jenner became famous and now spent much of his time researching and advising on developments in his vaccine.”

Religious-minded people of the era, Christians, specifically, were widely opposed to the concept of disease prevention by inoculation.

Sounds vaguely familiar, doesn’t it?

And yet, in the time since Jenner’s era,

Nose/Mouth Protection Was Once Popular Among Right Wingers

The now-defunct Moral Majority was a far-right-wing, extremist political arm of a primarily Protestant Christian Fundamentalist organization founded by the now-late Rev. Jerry Falwell, Sr. (1933-2007), Founding Pastor of Thomas Road Baptist Church, in Lynchburg, VA, who infamously filed, and lost, a defamation of character lawsuit against pornographer Larry Flynt (1942-2021), Founder of the Hustler magazine empire, which was ultimately appealed to the U.S. Supreme Court.

Based upon First Amendment principles, the SCOTUS found that Flynt’s plainly-marked parody depiction of Falwell fell under protected speech, holding that “the First and Fourteenth Amendments prohibit public figures and public officials from recovering damages for the tort of intentional infliction of emotional distress by reason of the publication of a caricature…” and noted that “the State’s interest in protecting public figures from emotional distress is not sufficient to deny First Amendment protection to speech that is patently offensive and is intended to inflict emotional injury when that speech could not reasonably have been interpreted as stating actual facts about the public figure involved.”

Moral Majority Report, July 1983, AIDS

In other words, the First Amendment protects parodies of celebrities or other public figures, even if they are intended to cause distress to the subjects depicted/portrayed.

Such a matter is now ongoing and involving soon-to-be-former U.S. Representative Devin Nunes, a Republican who has represented California’s 22nd Congressional District since 2003. CD 22 is in the state’s fertile San Joaquin Valley farmland area, and encompasses parts of Fresno, and Tulare counties, which includes portions of the cities of Fresno, and all of the cities of Clovis, Tulare, and Visalia.

Nunes is infamously litigious, and as some would characterize it, is thin-skinned, and becomes very “butt-hurt” when he is mocked, satirized, or parodied publicly, which has occurred regularly on Twitter, where the satire account “Devin Nunes Cow” (Nunes has interests in dairy farming in the district), and several other parody accounts, including some naming his mother, regularly poke fun of him.

Ironically, the two men Falwell and Flynt, later became good friends, and frequently appeared together in several public venues on college & university campuses, including on the Larry King Show.

Dr. Heather Murray, PhD, an Associate Professor of History at the University of Ottawa, Canada, (see her faculty page here) recently wrote the following, in part, about the matter of the far-right-wing now refusing to wear protective nose/mouth coverings (aka “face masks”) during the SARS-CoV-2 novel coronavirus (aka COVID-19) pandemic, whereas once, they were gung-ho to wear them, despite the fact that

A Baptist and a Methodist walk into a bar…

They’re both shot dead by the Church of God, who is then fought by the Assembly of God, and then attacked by the Church of Christ; and next, the Mormons come along, who are suddenly blindsided by the Jehovah’s Witnesses and the Seventh Day Adventists, while the Catholics & Episcopalians both fight the Presbyterians & Lutherans on the side. In walk the Moonies with the Unitarians, and everybody turns on them. Meanwhile, the Quakers, the Amish, Mennonites, and Buddhists stand by and watch it all unfold.

That’s the gist of what’s happening in the Middle East— a bunch of goddamn religious nuts fighting each other over their private interpretation of their preferred religion.

Here in America, goddamn religious nuts want to inject their preferred flavor of religion into government (which the Constitution specifically forbids) by sticking their noses into other peoples’ private lives, outlawing certain medical procedures which they find objectionable (What’s next? Colonoscopies? Pap smears? Testicular exams?), forbidding birth control, in vitro fertilization, freezing embryos, stem cell research, denying sex education and healthcare to everyone, while they secretly molest children, young girls, and teens, then go preach about “sin” and “love” afterward, and tell their parishioners along with the news media that Wiccans and Satanists had been doing it all along, by calling it “Satanic Ritual Abuse.”

That poor ol’ mythological “devil” is an easy punching bag, and catches hell for everything. Must be why the Rolling Stones composed “Sympathy for the Devil” in 1968.

After speaking a few magic words, and waving his magick wand, (on table) God pulls the unimaginably vast cosmos out of his top hat.

Meanwhile the widow, the orphan, prisoners, the stranger among you, and the least of these all look at them in dismay and wonder if there really is any such thing as “god,” because from their perspective, it sure doesn’t look like it.

Fuck ‘em all.

Every goddamn rotten one of ‘em — the dirty rotten religious bastard hater hypocrites.🖕🏽

They’re no better than the goddamn Muslims who are at each others’ throats.

And according to the bizarre monotheistic Judeo-Christian-Islamic mythology, not only are they a bunch of inbreds, anyway, but their “god” is a magician who spoke a few magic words and *!*POOF*!* like a rabbit out of a top hat, everything just appeared out of nothing everywhere (ex nihilo, it’s called in their theological seminaries)… in 6, literal 24-hour periods.

That’s not even a good fairy tale.

Then, there’s their “giant boat that saves the world” myth – or, at least

Birth of a Myth: How Ivermectin Got Mixed Up With COVID-19

Dr. Carlos Chaccour, PhD

Dr. Carlos Chaccour, PhD, Assistant Research Professor, Barcelona Institute for Global Health, and Chief Scientific Officer of the Unitaid-funded BOHEMIA consortium project in Barcelona, Spain, is a scientist and researcher whose primary area of scientific interest is with Emerging Viruses, Malaria, and Coronavirus.

For the last 10 years, his most intense professional focus has been upon “the development of mosquito-killing drugs (endectocides) as complementary vector control strategy for malaria control and elimination.” In fact, the specific area in which he “obtained his PhD in 2015, was working with slow-release ivermectin formulations for that purpose.”

Dr. Joe Brew, PhD

In May 2020, he, along with fellow researchers  Dr. Joe Brew, PhD, a Data Scientist, Epidemiologist, and Economist; and Dr. Alberto García-Basteiro, MD, Assistant Research Professor at the Barcelona Institute for Global Health, ISGlobal in Barcelona, Spain, and physician at the International Health Service of Hospital Clínic, authored “Ivermectin and COVID-19: How a Flawed Database Shaped the Pandemic Response of Several Latin-American Countries.”

Dr. Alberto Garcia-Basteiro, MD

Their critical examination was in response to efforts by healthcare professionals and officials in the nations of Peru, Bolivia, Paraguay, and Colombia who suddenly began taking an unusual interest in ivermectin, and using it on COVID-19 patients in their respective nations. Those nations’ officials were motivated, in large part by a since-retracted, and debunked manuscript initially placed on a “preprint server,” a website which publishes online, a full draft of research which has not yet been validated by the peer-review process. The respected healthcare/medical science journal Lancet, which has been continually published since 1823 with the objective to improve people’s lives, states that “a preprint is a version of a scientific manuscript posted on a public server prior to any formal peer review.”

Specifically, Dr. Chaccour and colleagues examined antiviral research published June 2020 in Science Direct entitled “The FDA-approved drug ivermectin inhibits the replication of SARS-CoV-2 in vitro,” i.e., in glass, such as test tube, beaker, or Petri dish, which was performed early in April by Australian researchers Leon Caly, Victorian Infectious Diseases Reference Laboratory, Royal Melbourne Hospital, At the Peter Doherty Institute for Infection and Immunity, Victoria, Australia, Julian D. Druce, Senior Medical Scientist in the Virus Identification Laboratory of the Victorian Infectious Diseases Reference Laboratory, et al, which “used concentrations that are not readily achieved in the human body” but raised enough interesting questions that further investigation was warranted, and because of “the drug’s excellent safety profile and lack of effective treatment for COVID-19.”

In response to their critical examination, and genuine questions about the techniques and methods, they wrote a guest editorial entitled “Ivermectin and COVID-19: Keeping Rigor in Times of Urgency” which was

Research: Moderna’s mRNA COVID-19 Vaccine MORE EFFECTIVE Than Estimated

Scientists and researchers have released their findings of the effectiveness of Modern’s mRNA COVID-19 vaccine. Initial scientific estimates were that the vaccine would have an effectiveness of 68.5%. But after the lengthy process of laboratory analysis of large groups of participants, scientists found that the vaccine is 96.1% effective after both doses have been given. And, only about one-half of one percent of the recipients had any serious side effects – a phenomenally low rate.

The long-awaited results of an immunity effectiveness study of Moderna’s mRNA COVID-19 vaccine have been released.

And, there’s GREAT NEWS!

In part, laboratory test findings of  30,415 individuals who participated in the study from July 27, 2020 to October 23, 2020, have shown that the Vaccine is

MUCH MORE EFFECTIVE THAN PREVIOUSLY ESTIMATED!

Sneak Preview

The paper entitled “Immune Correlates Analysis of the mRNA-1273 COVID-19 Vaccine Efficacy Trial” – on the preprint server (a “sneak preview” before being officially published in a scientific journal) – may be found here: https://www.medrxiv.org/content/10.1101/2021.08.09.21261290v1

Pertinent excerpts in red from the paper follow. 

Effectiveness First Estimated At 94%

Background — In the Coronavirus Efficacy (COVE) trial, estimated mRNA-1273 vaccine efficacy against coronavirus disease-19 (COVID-19) was 94%. SARS-CoV-2 antibody measurements were assessed as correlates of COVID-19 risk and as correlates of protection.

How do we identify correlates of protection?

• “Correlates of protection are generally identified by comparing the immune response of those protected by the vaccine and so called ‘breakthrough cases’, where clinical disease manifests despite prior vaccination. In the case of the COVID-19 pandemic, the numerous vaccines developed have proven very effective with low incidences of breakthrough cases making the identification of potential correlates of protection a slow process. As a result, comparisons with previously published data relating to both natural infection and vaccine studies have been drawn.”

Blood Levels Checked 3 Times

Methods — Through case-cohort sampling, participants were selected for measurement of four serum antibody markers at Day 1 (first dose), Day 29 (second dose), and Day 57: IgG binding antibodies (bAbs) to Spike, bAbs to Spike receptor-binding domain (RBD), and 50% and 80% inhibitory dilution pseudovirus neutralizing antibody titers calibrated to the WHO International Standard (cID50 and cID80). Participants with no evidence of previous SARS-CoV-2 infection were included. Cox regression assessed in vaccine recipients the association of each Day 29 or 57 serologic marker with COVID-19 through 126 or 100 days of follow-up, respectively, adjusting for risk factors.

Neutralizing Antibody Levels Highly Predictive Of Immune Protection

• Vaccine 96.1% Effective
• Vaccine EXTREMELY Safe — under ½ of 1% had serious side effects

Results — Day 57 Spike IgG, RBD IgG, cID50, and cID80 neutralization levels were each inversely correlated with risk of COVID-19: hazard ratios 0.66 (95% CI 0.50, 0.88; p=0.005); 0.57 (0.40, 0.82; p=0.002); 0.41 (0.26, 0.65; p<0.001); 0.35 (0.20, 0.60; p<0.001) per 10-fold increase in marker level, respectively, multiplicity adjusted P-values 0.003-0.010. Results were similar for Day 29 markers (multiplicity adjusted P-values <0.001-0.003). For vaccine recipients with Day 57 reciprocal cID50 neutralization titers that were undetectable (<2.42), 100, or 1000, respectively, cumulative incidence of COVID-19 through 100 days post Day 57 was 0.030 (0.010, 0.093), 0.0056 (0.0039, 0.0080), and 0.0023 (0.0013, 0.0036). For vaccine recipients at these titer levels, respectively, vaccine efficacy was 50.8% (−51.2, 83.0%), 90.7% (86.7, 93.6%), and 96.1% (94.0, 97.8%). Causal mediation analysis estimated that the proportion of vaccine efficacy mediated through Day 29 cID50 titer was 68.5% (58.5, 78.4%).

• causal mediation analysis – mathematical test determining: 1.) Total effect of X on Y; 2.) Relationship between X and M; 3.) Relationship between M and Y, controlling for X, and; 4.) Determining if M is a full, or partial mediator. Mediation is the process through which an exposure causes disease.

Bacon Dangerous? More Than You Probably Wanted To Know.

NOTE TO THE READER: It’s almost impossible to discuss food and its preparation these days without getting into history, and business ethics practices. But before you go off half-cocked, know for a certainty that in NO WAY am I opposed to the consumption of pork, nor of bacon, neither of the flesh of any animal. Presumably, because you’re now more curious, you must read further to more precisely determine what is meant by the headline — especially, and particularly if you enjoy bacon.

Earlier, I had replied to a friend who complained about having eaten “a cheeseburger for lunch and was tired and sleepy for most of the afternoon.”

My initial thought and response was “carbohydrate-induced somnolence,” and I wrote that “the meat patty was the only source of protein in the meal – if all you had was a cheeseburger. If you had fries with them, [that was] more simple carbs.”

Giving a rather simple analogous explanation, I stated that, “the (most likely highly-processed white) bread: Simple carbs – they burn quickly – like a bottle rocket. Up quick, burns out just as quickly.”

And from there, I wrote further about the addition of cheese on the burger, by writing “Cheese: Most likely “American” which is not genuinely cheese.”

From Cheese.com:
“American cheese is processed cheese made from a blend of milk, milk fats and solids, with other fats and whey protein concentrate. At first, it was made from a mixture of cheeses, more often than not Colby and Cheddar. Since blended cheeses are no longer used, it cannot be legally called “cheese” and has to be labelled as “processed cheese,” “cheese product,” etc. Sometimes, instead of the word cheese, it is called “American slices” or “American singles.” Under the U.S. Code of Federal Regulations, American cheese is a type of pasteurised processed cheese.”

“… it’s not actually cheese—at least, not legally. The FDA calls it “pasteurized processed American cheese product.” In order for a food product to be a true “cheese,” it has to be more than half cheese, which is technically pressed curds of milk. Each slice of American contains less than 51% curds, which means it doesn’t meet the FDA’s standard.”

And, here’s the Code of Federal Regulations on the matter:
Title 21, Volume 2 — 21CFR133.169 — Revised April 1, 2020.
PART 133 — CHEESES AND RELATED CHEESE PRODUCTS

Subpart B – Requirements for Specific Standardized Cheese and Related Products

Sec. 133.169 Pasteurized process cheese.

Food — it’s production, variety, growing, farming, harvesting, preparation, etc. — is an interest of mine, and like many others, I enjoy not only a good meal, but also have an interest in some understanding about the whys and wherefores of a particular dish’s origins — its history — which also give greater, and a more full understanding to us in numerous ways.

Nitrite-free, dry cured, air dried, pork bellies which will become bacon.

For example, the simple, almost ubiquitous dish of beans and rice is a fully complemented dish, meaning that it has a full and complete range of proteins. Beans, by themselves have very little protein, and are primarily carbohydrates, and the same holds true for rice – very little protein, and is primarily a carbohydrate. And the proteins that each separate food has – the rice and the beans – are not “complete” proteins, meaning that individually, they do not contain the 9 essential amino acids which are found in “complete” proteins, and which are necessary in order to build and repair protein tissues (muscles) in the body.

Without exception, ALL animal-based food — regardless of the origin/source — contain complete proteins, and that includes eggs, as well as muscle and organ tissue, though it does not include fat. Fat, however, is never found outside the presence of protein. Fats and proteins could be thought of as “kissing cousins,” because they’re ALWAYS found in combination with each other. They are NEVER apart. Where there’s fat, there’s protein. As an example, consider natural peanut butter — that is, peanut butter which only added ingredient is salt. Peanuts and salt SHOULD BE the ONLY ingredients in peanut butter, and technically, as well as legally, they are, but so many other products are mistakenly called “peanut butter” when they’re actually “peanut butter spread” or something else entirely different.

A simple, even cursory, examination of the labels of Jif®, Skippy®, Peter Pan®,  and other brands – including their websites – demonstrates that in the exceeding majority of cases, their most well-known, and most widely-sold products are NOT authentically genuine peanut butter. Each of those, and others’, products labels and websites state that their products are “peanut butter spreads,” rather than being “peanut butter.”

Peter Pan® brand is manufactured and distributed by Conagra Brands, while Jif® is owned by The J.M. Smucker Company, and Skippy® is owned by Hormel Foods, LLC.

The previous citations were necessary in order to understand what follows, to demonstrate that just because people call a thing by some name, the name by which they call it is not necessarily the proper term. A four-legged animal with hooves and horns could be a bull, a boar, a ram, or a buck, and are all males of the species of cattle, hogs, sheep, goats, and deer. But they’re not females.

And while we’re continuing on the topic of food…

I have come to loathe most commercially-available “bacon.”

Why?

Not only does it taste retched, but also because in the classic, traditional sense, it is NOT bacon.

Yes, it comes from a hog – and not always pork bellies – but the method in which it’s made (“processed,” would be a much more accurate term) bears little resemblance to traditional bacon. Modern “bacon” is flash-smoked, pressure-processed with nitrites, salt-cured, and hustled out the factory door just as quickly as possible in order to continue reaping corporate profits for their Wall$treet masters.

See: USDA Food Safety Inspection Service circular, “How is bacon made?” –and– “What are the methods of curing bacon?” –and– “What are nitrosamines and what cooking methods minimize their formation?” –and– “Can bacon be made without the use of nitrite?”:
https://www.fsis.usda.gov/food-safety/safe-food-handling-and-preparation/meat/bacon-and-food-safety

Traditional, original “Old Skool” bacon was/is often smoked in a smokehouse, which not only imparts unique flavor and aroma, but is an important part the preservative curing process – the main intent of which was/is to retard the spoiling process – or turned rancid, the term applied to fats and oils which have spoiled – “spoilage” being oxidation, including discouraging growth of

Smart Phones and Dumb People

Recently, I got to wondering about why some folks haven’t fully embraced the COVID-19 vaccines available in the United States. “Fully embraced” as in a significant majority of folks who have received it nationwide. That includes the naysayers, most folks in the South, certain Republicans, and some others… including — believe it, or else — some healthcare professionals. Anti-vaxxers are excluded, of course, because they’re against every vaccine. Idiots.

Would that there were one for stupidity. It should be mandatory at birth, and for everyone. Maybe if it were called a “smart pill,” that’d help. We have “smart phones,” and plenty of dumb people. It just isn’t right.

But I digress.

Some folks have said that they don’t “trust” the vaccines, for one reason, or another. So far, no one’s been abducted by aliens after receiving a COVID-19 vaccine, and that I’m aware, no one’s hair has tried to call Bill Gates after they received a COVID-19 vaccine. But Congress and the Department of Defense have released videos of what we once called “UFOs” – Unidentified Flying Objects. Now they’re called UAPs — Unidentified Aerial Phenomena. But I still like UFO. Still, no one knows what they are. Hence, the name. And quite fortunately, there’ve been no reports of folks growing tails and swinging from trees afterward, either. But doubtless, some have eaten bananas. Point for lower primates: 15 – love.

So we’ve moved from the known (stupid folks who don’t get vaccinated), to the unknown (mysterious video imagery of UFOs making some very impressive maneuvers).

But what is it that we don’t know? And how do we know what we know? As the late Donald Rumsfeld, then Secretary of Defense once said

“In 2018, 39,740 individuals in the United States were killed by firearms, making firearm violence the second leading cause of injury death in the United States (Centers for Disease Control and Prevention [CDC], undated).

“As part of the Gun Policy in America initiative, RAND researchers developed a longitudinal database of state-level estimates of inpatient hospitalizations for firearm injury between 2000 and 2016. This database was first released in 2021 and is free to the public.

RAND researcher Dr. Andrew Morral, PhD who is the Senior Behavioral Scientist, and Director of the National Collaborative on Gun Violence Research there, tweeted recently (April 28) that:

“Why are firearm hospitalizations not correlated with gun ownership in observed state hospitalization data or our estimates? Because they chiefly result from criminal assaults (vs. suicides) and these are not correlated with household gun ownership.”

This type of research is a phenomenally difficult proposition, and highly complicated undertaking, and the entirety of the paper is spent detailing and explaining their methodology, and sources, because not every state provides information to, or participates in HCUP, the Healthcare Cost and Utilization Project.

As well, data had to be compared and cross-referenced with other similarly related databases, such as the FBI’s annual UCR – Uniform Crime Report.

And then, they get into the math – the statistical analysis – and explain the formulae used, which then has to be checked with other external mathematical models to determine, and ensure a high level of accuracy. In short, this is not “relaxing reading” by any stretch of the imagination – it is highly technical explanations of phenomenally difficult work, which only indirectly points to the significance of their findings.

HCUP is the Nation’s most comprehensive source of hospital care data, including information on in-patient stays, ambulatory surgery and services visits, and emergency department encounters. HCUP enables

Gun Ownership + Carrying + Impulsivity = Increased Firearm Violence Victimization & Death Risk

Think you need a gun “for protection”?

Think again.

The glibly superficial “good guy with a gun” notion is but a trite and specious fallacy.

Research has shown that “that individuals in possession of a gun are over four times more likely to be shot in an assault than those not in possession.”¹

Thus, while gun carrying itself is not a violent behavior, “it potentially marks heightened risk among gun carriers.”

And indeed, “research has demonstrated a strong link between (gun carrying) and gun violence victimization.”¹

“The finding has important implications for states and campuses considering open carry laws α while these policies may be intended to increase safety, they may have the unintended result of increasing gun violence victimization.”²

“On average, guns did not protect those who possessed them from being shot in an assault.³ Although successful defensive gun uses occur each year, the probability of success may be low for civilian gun users in urban areas. Such users should reconsider their possession of guns or, at least, understand that regular possession necessitates careful safety countermeasures.”

“Impulsivity was identified as

CORONAVIRUS may NEVER “Go Away”

Welcome to the “new” reality.

But, just for a moment, let’s play “What if?”

What if the United States’ failed response (because of the inactions and deliberate failures of the previous administration) was the primary cause of the mutated, more virulent variants?

It’s entirely plausible.

Otherwise, how to explain that the United States, with the world’s 3rd most populous nation – China and India each have WELL OVER 1 BILLION MORE – has ABSOLUTELY THE WORLD’S WORST COVID-19 INFECTION RATE?

Other nations, most notably New Zealand, have had phenomenal success in keeping the disease at bay, relatively speaking, as have a few other nations, including China, India, Greenland, Australia, other Scandinavian nations, and… well, you get the picture.

Perhaps there should’ve been a sign:

New International Guidelines For Cannabis In Treating Chronic Pain

New Guidelines Issued on Medical Cannabis for Chronic Pain

International task force shares recommendations for dosing, administering.

by Ryan Basen, Enterprise & Investigative Writer, MedPage
September 13, 2020

---

Chronic pain patients can be treated with medical cannabis following one of three protocols based on patient characteristics, according to an international task force at the virtual PAINWeek meeting.

Note the words “NO OPIATES” PROMINENTLY displayed on the label.

Citing limited clinician knowledge about medical cannabis treatment and the opioid crisis, one task force member said the recommendations are timely.

“We as a task force believe it’s extremely important to bring [medical cannabis] to patients,” Alan Bell, MD, of the University of Toronto, told MedPage Today. “Our main focus was to provide directions to clinicians.”

Medical cannabis has been suggested to treat chronic pain, the task force noted, but too many providers still do not utilize it because there has not been accepted guidelines about dosing and administration. Others prescribe medical cannabis without knowing how patients can properly dose.

“There’s a huge knowledge gap and no way clinicians can fall back on a specified dosing regimen,” Bell said.

Led by Arun Bhaskar, MD, of Imperial College Healthcare NHS Trust Pain Management Centre in London, the 20-clinician Global Task Force on Dosing and Administration of Medical Cannabis in Chronic Pain used a modified Delphi process. Among their recommendations:

• Treat the majority of patients along the “routine” scale. This means

Contradicting Tennessee Governor Bill Lee On Abortion

I’d like to address this entry to Governor Lee, and to every other person who, for whatever reason, opposes abortion – though opposition to the procedure is mostly religious-based, and that itself presents a Constitutional problem, insofar as our nation is not established upon any religion, and I mean specifically to refer to the “Establishment clause” of the First Amendment. I am NOT going to argue religion, that is for theologians, and I am not making a theological argument.

First, it is a very dangerous precedent to write a law that not only eliminates one’s ability to make an independent, and informed decision (about that, or any other private matter), but mandates that the government tell you (or anyone) what to do in your private life. That is the essence of what is happening with this type of argument. Proponents are: 1.) Forbidding exercise of Constitutional rights and freedom to make a free-will decision, and; 2.) Essentially forcing the pregnant woman to give birth to the child.

Regardless of whether one agrees, or not, that abortion should be discouraged, or even made illegal, the essence of what is happening is that, when government gets involved in a personal, private matter, there is no longer just a woman, and her physician, in that private treatment room, but 535 other people – 435 Representatives, and 100 Senators. And that’s just too many people in one small room.

Whenever government steps in and makes decisions for you, you no longer have freedom, you no longer have liberty. And whether they realize it, or acknowledge it, or not, that’s what the anti-abortion activists want – for government to make your decision, or more accurately, to deny you the ability to make a decision… one with which they disagree with upon religious grounds. Not only is that is the VERY antithesis of so-called “smaller, less intrusive” government (something about which GOP types have clamored about), but it is “Big Brother” government, another thing about which most right-wing, and GOP-type folks complain.

Second, contrary to the claims made by

“Just say ‘NO’” has never worked. Here’s what does.

Freedom.

What a concept, eh?

The very idea that you have a brain, and therefore, can think independently to decide FOR YOURSELF what you want, or ought, to do, continues to frustrate others who think that they know better than you do what personal decisions you should make for yourself!

It’s an adult decision.

Why, it’s nothing short of… LIBERTY!

ENOUGH! of the “Nanny State”!

Take your religion home, and GET IT OUT OF GOVERNMENT!!

Practice it PRIVATELY, with your family, friends, and other like-minded individuals. STOP forcing your PRIVATE religious ethics and morals upon others by writing public laws that mirror your private interpretation of your religion.

Thomas Jefferson wrote a letter to the Danbury Baptists that cited the establishment clause of our nation’s Constitution, which as he wrote, erected a “a wall of separation between Church & State,” or as we now say, between government, and religion.

Religious nuts have been trying to tear it down, ever since.

And they’re STILL TRYING TODAY!

‘Drug Use For Grown-Ups’ Serves As An Argument For Personal Choice

If you grew up scared of what illicit drugs could do to you — hearing about all the horrors that could befall you from everyone from Nancy Reagan to your parents — the threat may have felt very real: If you actually took a puff off that joint that the kid who slept through math class offered you, it could lead to failed relationships, chronic unemployment, self-destruction.

The shame would outlive you.

But drugs are a more complicated matter than they’ve been made out to be, according to Dr. Carl L. Hart. In his new book Drug Use for Grown-Ups, the Columbia University professor of psychology and psychiatry zealously argues that drug use should be a matter of personal choice — and that, in more cases than not, personal choice can lead to positive outcomes. His positions may seem quite extreme to some but they also, by and large, make a lot of sense — and are backed up by ample research.

A major reason drugs have such a negative public image, Hart asserts, is racism. He notes that after the Civil War, some Chinese railroad construction workers smoked opium and, sometimes, established “opium dens” to do so. Over time, more and more white Americans visited these dens to smoke opium too. That in turn led to broader, bigoted social fear among whites, like, for example, the sentiments captured in H.H. Kane’s 1882 report:

“The practice spread widely…Many women and young girls, as also young men of respectable family, were being induced to visit the dens, where they were ruined morally and otherwise.”

Then there was the post-Civil War use of cocaine among some Black day laborers, something Hart writes was at first encouraged by white employers because of the productivity it could promote. Soon enough, however, articles appeared widely that tried to make a connection between African American cocaine use and criminality. One particularly egregious article in The New York Times in 1914, cited by Hart, even reported that some police in the South “who appreciate the vitality of the cocaine-crazed” were switching to higher-caliber weaponry capable of “greater shocking power for the express purpose of combating ‘the fiend’.”

But horrifying history aside, one of the book’s most eye-opening aspects is its challenge of the long-running association between drugs and addiction. First the basics: Addiction, according to the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM – 5), must be a source of distress for a drug user. It must also interfere with a person’s job, parenting or personal relationships. Other indications of addiction may be

A COVID-19 vaccine was ready January 13, 2020 – long before the pandemic began.

Margaret Keenan, a 90-year old Irish-English grandmother, was the world’s first to receive a coronavirus vaccination.

While the world is crowing about Margaret Keenan, a 90-year old Irish-British grandmother of four, being the first in the world to receive a coronavirus vaccine yesterday, on Tuesday, December 8, 2020, around 0630 local time (GMT) – she received the version collaboratively developed by the American company Pfizer and German company BioNTech – the American biotechnology company Moderna, in Massachusetts, had long had a vaccine developed.

Moderna had already designed a COVID-19 vaccine – mRNA-1273 – by January 13.

It was only recently, on  November 16, that they reported a 94.5% efficacy rate.

Moderna developed their vaccine only two days after the genetic sequence had been publicized internationally by Chinese researcher Professor Dr. Yong-Zhen Zhangm Ph.D. His humanitarian act of scientific generosity resulted in him being temporarily forced out of his lab.

Professor Dr. Zhang believes science holds the key to predicting viral outbreaks with similar accuracy as with which we now anticipate typhoons and tornadoes. He said, “If we don’t learn lessons from this disease, humankind will suffer another.”

Moderna’s vaccine design only took one weekend to develop at their Massachusetts facilities.

In fact, Moderna had completed development of their COVID-19 vaccine mRNA-1273 before the Chinese government had acknowledged the disease was transmitted by human-to-human means, and more than a week before the first confirmed coronavirus case in the United States – January 21.

And by the time the first American coronavirus death was reported a month later, on February 29, Moderna’s mRNA-1273 coronavirus vaccine had already been manufactured and shipped to the National Institutes of Health to begin its Phase I clinical trial.

All of that was long before the President had made any announcement about his “Operation Warp Speed,” the public-private partnership to develop a coronavirus vaccine, and yet even 2 months before Bloomberg News reported on April 29 that such a plan was in the works.

Regarding the announcement of the first known coronavirus-related death, it should be noted that, following autopsy results in mid-to-late April, the Santa Clara County California Medical Examiner’s office reported on April 21 that the first known COVID-19 related death occurred in United States on February 6. The first death was previously thought to have occurred in Kirkland, Washington on February 29. The New York Times reported that, “The virus has an incubation period of 14 days and people who die of it are often sick for at least three weeks, so the individual who died on February 6 could have been infected — and transmitting the infection to others — in early January, experts said.”

In essence, what that means, is that for the entire time the COVID-19 coronavirus pandemic has infected well over 15 million – and counting – in the United States, we had the tools we needed to prevent it, as well as the death of over 250,000 Americans… and counting.

So, that begs the question: If Moderna had a vaccine ready in January, why has it taken until now – December, very nearly a year later – to have a vaccine readily available?

Moderna, a publicly-traded company (stock symbol: MRNA) with operations and headquarters in Massachusetts, is a biotechnology firm focused exclusively upon development of vaccines using mRNA – messenger RNA. Their vaccine is the first in the history of vaccine development to use mRNA.

Drs. Emmanuelle Charpentier-L & Jennifer A Doudna-R, are 2020 Nobel laureates, and creators of the CRISPR/Cas9 gene editing tool

Vaccines made using mRNA are fundamentally different from any other vaccine ever made. The history of vaccination began on May 14, 1796, when a country doctor from Gloucestershire, England, Dr. Edward Jenner, MD, first took some fluid from a cowpox blister and scratched it into the skin of James Phipps, an 8-year-old boy.

Dr. Jenner developed his vaccine while he was still a medical student, after noticing that milkmaids who had contracted a disease called cowpox, which caused blistering on a cow’s udders, did not catch smallpox. However, unlike smallpox, which caused severe skin eruptions and dangerous fevers in humans which often led to death, cowpox led to few ill symptoms in those women.

Science has come a very long way since then. While traditionally, vaccines were first made using active, live, then attenuated, then inactivated, or dead cells from the organism or virus. Throughout the history, the process of making vaccines used chickens’ eggs for the protein they contained, and were literally injected into the shell of an egg. Some are still made that way.

Most recently, two women have forever changed health, medicine, and many other life sciences, which gives hope to millions, and holds untold promises. Dr. Emmanuelle Charpentier, Ph.D., Director of Infection Biology at the Max Planck Institute, and Professor Dr. Jennifer A. Doudna, MD, Ph.D., Professor of Chemistry, Biochemistry & Molecular Biology, Li Ka Shing Chancellor’s Professor in Biomedical and Health at the University of California Berkeley, in October 2020 won the Nobel prize in chemistry for the development of the revolutionary CRISPR/Cas9 gene editing tool which has been described as enabling “rewriting the code of life.”

Drs. Emmanuelle Charpentier-L & Jennifer Doudna-R, are the 2020 Nobel laureates in chemistry, and creators of the CRISPR/Cas9 gene editing tool.

Cas9 is a type of modified protein and acts like a pair of scissors that can cut parts of DNA strands. CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats, in essence, a repeating mirrored DNA sequence in genomes that repeats. The technology has worked in most every organism that it has been used on, including plants, animals, microbes and humans.

By using the gene editing platform CRISPR, which could be thought of as cut-and-paste, the idea is to remove parts of a genome using RNA as a means of guiding to a particular place within a genome, genes can then be modified to eliminate mutated, or harmful parts.

The ability to use such sophisticated gene splicing technology holds enormous promise.

As it relates to the coronavirus, the gene splicing technology uses a very small portion of messenger RNA (mRNA) from the coronavirus genome, and produces a gene that codes for the spike protein – the characteristic protruding part seen on images.

The coronavirus has 4 proteins, the spike is 1, and is the part that enables the virus to invade cells. By using only that part of the virus, it causes the body to produce antibodies that neutralize that spike protein. RNA vaccines cause the body to make only that spike protein. Then, encased in a fat molecule mRNA then enters cells, and sends a coded message to the body to make the protein, which in turn causes an immune response.

RNA vaccines have many advantages, which, unlike other vaccines produced other ways, they stimulate the production of killer T-cells which stop the coronavirus from replicating. And because mRNA vaccines are produced in test tubes or tanks, rather than being cultivated in cells (such as in eggs), they should be relatively quick and easy to produce.

The use of mRNA to treat disease, even genetic-based disease, such as cystic fibrosis, is brand new, but holds exciting possibilities. Moderna is perhaps one of the most promising mRNA therapeutics research firms in the world. And under the leadership and direction of Chief Science Officer Dr. Melissa Moore, Ph.D., Moderna has developed, and publicized, the scientific blueprint for a unique form of cancer therapy using mRNA which when used used, ensures its mRNA is made only inside cancer cells. Ryan Cross reported in Chemical and Engineering News on September 3, 2018 in “Can mRNA disrupt the drug industry? Messenger RNA technology promises to turn our bodies into medicine-making factories. But first Moderna—and a long list of old and new competitors—needs to overcome some major scientific challenges.” and wrote in part that, “Moderna scientist Ruchi Jain designed an mRNA that causes cancer cells to self-destruct but is recognized by, and destroyed in, healthy cells.”

Dr. Moore has a distinguished scientific pedigree, and

The Direction America Should Go In, Is…

Most polls which ask the question “Do you think America is headed in the right direction?” find that an exceeding majority of respondents answer “NO” to that very simple, straight-forward question.

Since January 2009 to today (October 13, 2020), those who believe the country is on the wrong track has ranged from a high of 76.5% to a low of 45.8%, with the majority occurring in the 60% range for most of that time, who think the country is headed in the wrong direction. That’s according to the averaged aggregate polling data collected by RealClearPolitics from a variety of polling organizations.

About the President, some have intoned sarcastically, “Poor ol’ Trump is the only President that has ever made mistakes.”

No, of course not, and it’s easy to understand the tenor and gist of such sarcasm.

Flooding by Hurricane Katrina in New Orleans

I can say, have said, and will say this, however, and it is that, to date, in our nation’s history, he is the ONLY President whom has NEVER held any office of Public Trust of any kind, whatsoever – neither elected nor appointed – nor has he EVER volunteered for or with any kind of Public Service in ANY capacity with any public policy or public service-based organization. And for that reason, he is as unfit for duty as his bone spurs made him during Vietnam.

While many criticize and make political hay out of regarding a candidate’s “inexperience,” and tout that as being a strong point of benefit, there is this to consider – which I’ll explain using analogy.

Most people are employees. They have a job to do, and do it well. But they’ve never owned, nor run a company of any kind.

So it would be utterly preposterous, absurd, and even stupid, to imagine that just anyone would be able to step into Jeff Bezos’s shoes (Amazon’s Founder, President, CEO) and perform his job at least as good as he does.

We would be utter failures… just like the President is.

Another part of that problem is that the President’s “mistakes,” or “failures,” as they’re properly called, affects 330,441,455 people, and the world’s LARGEST economy.

And on that note, I’ll make this observation:

As the world’s 3rd most populous nation, to China and India, respectively, each with over 1 BILLION MORE people than we have, it is the height of absurdity and preposterousness to imagine for even a moment that somehow, with that many people and STILL GROWING, that we should somehow have a “smaller” government is not merely stupid, it is moronic.

Analogously again, it’s like imagining that you should wear smaller clothes the bigger you get. It’s nonsensical on the order of Alice in Wonderland.

VERY few people want to talk about it, and even FEWER want to hear it, but… because our elected officials

It’s time to TAKE OUT THE TRASH IN NOVEMBER!

In an uncharacteristic move, The New England Journal of Medicine recently took a step which they have not since their 1812 founding.

 

A scathing editorial signed by all 34 editors of the publication – physicians, scientists, health researchers, and medical experts – acknowledged that in response to the COVID-19 pandemic, the President and his administration have “taken a crisis and turned it into a tragedy.”

The group minced no words in their scorching criticism of the President and his administration for their abysmal, still-ongoing failures which have claimed at least 212,466 lives, and counting, by writing that “Instead of relying on expertise, the administration has turned to uninformed ‘opinion leaders’ and charlatans who obscure the truth and facilitate the promulgation of outright lies.”

Solution being carefully poured into a petri dish that sits under a micro scope. A medical scientist wearing glasses can be seen concentrating as he pours from the glass flask. Selective focus.

Noting that physicians and other healthcare professionals face the possibility of lawsuits, and loss of license for such malpractice, they acknowledged that the nation’s solitary recourse for political malfeasance is to vote him out of office, and wrote that, “Anyone else who recklessly squandered lives and money in this way would be suffering legal consequences. Our leaders have largely claimed immunity for their actions. But this election gives us the power to render judgment.”

They cited America’s Trump-led failures and wrote that in comparison to other nations, “We have failed at almost every step. We had ample warning, but when the disease first arrived, we were incapable of testing effectively and

His hypocrisy marks a 180° reversal from the weekend when Trump pushed for negotiators to reach an agreement, telling them to “GET IT DONE.”

The SOB in Chief just cut his own throat -and- that of every other GOPer in every down-ballot race in America.

He CONTINUES to shoot himself in the feet, and America in the head and back – execution style.

Expect a🌊BLUE🌊TSUNAMI🌊in November!!

By his intransigence, he has now set America on a guaranteed one-way course to GREAT DEPRESSION II.

And that EVEN AFTER Federal Reserve Chairman Jerome Powell warned of PERMANENT economic damage if additional support was not forthcoming.

The move marks a risky gamble

Scientific, Peer-Reviewed Study: Conservative-Only News Consumers Ill Informed, Believe COVID-19 Conspiracy Theories

No surprise there.

There’s a reason why Fox News is monikered Faux Noize.

The Republican party is NO LONGER the “Grand” Old Party.

It’s NOT the “party of Lincoln,” and hasn’t been for quite some time.

Since circa 1964, it’s been the party of the Ku Klux Klan, the John Birch Society, libertarians, and other radical elements. And, it was seriously ushered in during the Reagan administration when in his first inaugural address, the B-movie actor and longtime GE mouthpiece said in part that, “In this present crisis, government is not the solution to our problem; government is the problem.”

It’s easy to understand that if “government is the problem,” the solution to that problem is elimination of it. And that is anarchy. And yet, in his carefully crafted address, that was precisely what he was intimating – the abolition of government. For in his next sentence, he said, “From time to time we’ve been tempted to believe that society has become too complex to be managed by self-rule…”

It’s not difficult to see that his slashing of the Top Personal Income Tax bracket for the wealthiest Americans from 70% to 50%, and then to 28%, in conjunction with reductions in Capital Gains tax rates, and the “Paris Hilton Tax Cuts,” also monikered as the “Death Tax,” which is properly known as the Estate Tax, which only wealthy Americans have ever paid, was purposely designed to eliminate government, rather than to refine its operations, increase efficiency, or reduce fraud, waste, and abuse at any level.

When he said, “It is time to check and reverse the growth of government, which shows signs of having grown beyond the consent of the governed,” it could not have been made any more clear that his was a “starve the monster” approach to an alleged, though imaginary, and non-existing problem, that government was too big and the “monster” was the government.” And that was despite what he said in that same address that “Now, so there will be no misunderstanding, it’s not my intention to do away with government,”
because it couldn’t have been made more clear what his ultimate objectives were.

He again clearly identified government as being an evil monster when he said, “It is no coincidence that our present troubles parallel and are proportionate to the intervention and intrusion in our lives that result from unnecessary and excessive growth of government.” Hardly anyone could have done a better job of setting up a Straw Man Argument, for afterward, he beat that government straw man to a pulp.

Again, it is beyond the scope of the pale to imagine that a more populous nation would need fewer laws, or fewer people to efficiently and effectively conduct operations to provide for the demands and needs of more people. For that would be an inversely proportional relationship, that somehow a larger (more populous) nation, with more inventions, more businesses, more works of art, science, and other forms of creativity, would need fewer laws to govern their behavior and operations, and at some point in time, would eventually disappear.

The contradictions in his speech were blatant, and his intentions were fully uncloaked. Bluntly stating that “It is my intention to curb the size and influence of the Federal establishment,” he set about using his skills as an actor reassuring the people in a grandfatherly way that he had their best interests at heart, despite what he said otherwise.

The notion of “self-rule” is one which is emphasized by the ultra-radical group headquartered in Auburn, Alabama known as the Mises Institute, which promotes a heterodox economic world view, which includes anti-government sentiment, and the belief in the idea of anarchy – a world without government – and a “free market only” solution to everything as a one-size-fits-all solution to all problems.

Again, while Reagan was a B-movie actor, he was an actor nevertheless, and in his years on the stump for General Electric nationwide, he honed his public persuasion speeches to a fine edge, and was able to parlay that into a run for the White House which he won twice being monikered as the “Great Communicator.” But the language he used, while delivered quite well, was “dog whistle” language for anti-governmental radicals, all whom he welcomed into the GOP’s “Big Tent.”

The ground had earlier been ploughed at the 1964 Republican National Convention at Cow Palace in Daly City, CA (immediately adjacent and SOUTH of San Francisco) when then-NY Governor Nelson Rockefeller was granted 5 minutes to address the delegates to request adoption of language in the official party platform which would “repudiate here and now any doctrinaire, militant minority, whether Communist, Ku Klux Klan or Bircher which would subvert this party to purposes alien to the very basic tenets which gave this party birth.”

He was booed for over 16 minutes.

The language was simple, and read as follows:

Mayo Clinic to have COVID-19 Antibody Test by Monday

“How can I know if I’m FULLY recovered from COVID-19 novel coronavirus?” is a question that gets asked by many, particularly by those who have been infected by COVID-19.

Unfortunately – to this point, at least – the answer to that question has been “We don’t know.”

Fortunately, however, researchers have rapidly doubled-down on their research, intensified their efforts, and are becoming fruitful.

Here’s a brief story about one such effort.

Mayo Clinic expects COVID-19 antibody test to be ready Monday

Mayo Clinic Expects COVID-19 Antibody Test To Be Ready Monday

Pedestrians cross the street as they leave Mayo Clinic’s Gonda Building in Rochester, Minn., in 2016. Mayo researchers say they’re close to releasing tests that would tell whether a person has had and recovered from COVID-19.Alex Kolyer for MPR News file (Minnesota Public Radio)

Researchers at Mayo Clinic expect to release a test that would tell whether a person has had and recovered from COVID-19 on Monday. The Minneapolis Star Tribune reports the University of Minnesota is also narrowing in on an antibody test.

The tests would help public health officials understand the scope of the outbreak and identify people who could safely be in public to help with relief efforts. They would also help in an effort to treat critical COVID-19 patients with plasma from individuals who have recovered.

Elitza Theel is director of the Mayo Clinic lab testing COVID-19 antibody tests. She spoke with MPR News host Tom Crann Wednesday.

You can listen to the interview by clicking on the audio player above, or read the transcript below, which has been edited lightly for clarity and length.

Q: Tell us first, what is an antibody?

A: Antibodies essentially recognize the virus and can help inactivate and kill it.

It’s important to know that these types of tests are different than all of the molecular tests that are being done off of nasal swabs or throat swabs. Those tests detect viral genetic material [to show whether the coronavirus has infected that person].

These [blood serum] antibody tests are detecting a person’s immune response to that virus. It takes, in some cases, 10 to 11 days for a person to mount an immune response and produce these antibodies, so these tests aren’t going to be used as a diagnostic in patients that are presenting with two or three days of symptoms.

Q: Tell us how soon they’ll be ready

A: At Mayo, we hope to have it available as early as next week. We will be doing kind of a slow roll out because, similar to the situation with molecular tests, there’s a limited supply of these tests. We’re hoping that commercial manufacturers will ramp up here in the next few weeks so that we can make it available much more widely.

Q: Then it can go straight to to doctors, public health departments, or is FDA approval needed? How does that work?

A: FDA approval is not needed at this time. However, laboratories that are offering these tests have to go through a very rigorous verification process to make sure that the tests they’re offering provide the right results.

Clinicians will be able to order this in individuals who they think having are a result for would be helpful to either guide return to work [decisions] or further quarantining.

Also, you may have heard about the convalescent plasma treatment trials. As we wait for antivirals and vaccines to be developed and deployed, we need some sort of bridging therapy. So, the idea here is to identify individuals who have recovered from COVID-19, collect their plasma, make sure that it has the antibodies, and then use that plasma to treat acutely ill patients. We’re basically providing somebody else’s antibodies to ill patients who maybe don’t have an immune response mounted yet, and these antibodies would essentially help to fight off the virus.

Q: How close are we on plasma treatment?

A: Clinical trials are starting very soon, both here at Mayo Clinic as well as many other locations across the U.S.

Q: Why is it important to have this information about how many people have been infected, even if they are recovered?

A: There’s a couple of reasons. One, we know there’s a significant number of individuals who have been infected without symptoms. So, knowing the true number, the true denominator of individuals who have been infected with COVID-19, would allow us to determine the true case fatality rate. And then the other reason this is important is identifying when, as a community, as a region, as a nation, we’ve reached herd immunity status.

QUESTION: How should a clinician monitor the outcome of cannabinoid-based therapy?

ANSWER: As suggested by the Australian Centre for Cannabinoid Clinical and Research Excellence, monitoring should initially involve reviewing the patient weekly in person, and via phone if required in the interim between clinical reviews.
“There are three areas of outcomes that should be considered:
1.) Symptom control
“A pre-defined measure of success should be negotiated with the patient prior to commencement of therapy. This can be measured by using a validated tool, for example by the Palliative Care Symptom Assessment Scale.”
2.) Drug adverse events
“Careful monitoring of patients for adverse events and the need for a change in dosage is important. Adverse events may become apparent after commencement or after change in dose… Adverse events may be related to other concurrent medications. Doses of these medicines should be adjusted as appropriate.”
3.) Pathology monitoring
“Drug concentrations of drugs where there is a potential or actual drug-drug interaction may be important. Cannabidiol may cause hepatocellular injury. Patient’s liver function biochemistry should be monitored prior to initiation and periodically as clinically indicated.“

QUESTION: Some patients use cannabinoid-based medicines to treat nausea and vomiting. Is one of the side effects of cannabinoid-based medicines nausea/ vomiting?

ANSWER: Yes. The adverse event profile of cannabinoid-based formulations is dependent upon the ratio of CBD:THC, the presence of other cannabinoids and terpenes, and the dose consumed. The known common adverse effects of cannabinoid-based medicines include sedation/somnolence, dizziness, anxiety, cognitive dysfunction, nausea, vomiting, diarrhea, vertigo, increased or decreased appetite and dry mouth.

QUESTION: Even if an individual employs the same mode of administration over time, the effects of cannabinoids may change for that individual. Provide some reasons why this may be so.

ANSWER: The effects of cannabinoids may change over time due to multiple factors, including:
• Tolerance to the cannabinoids may develop
• A change in the patient’s health status/ medical condition may change over time and lead to physiological changes in the endocannabinoid system (For example, inflammation impacts the ECS. Also, impaired G.I./liver function affects the absorption and metabolism of cannabinoids.)
• The patient may start or stop taking a medication that interacts with cannabinoids or affects the metabolism of the cannabinoid-based product.
• Physiologic changes in the endocannabinoid system take place as patients age.

QUESTION: The effects of cannabinoids are dependent upon the route of administration, the health of the consumer and other factors. There is also interindividual variation. Provide some reasons why the effects of cannabinoids vary among individuals.

ANSWER: There are many reasons why the effects of cannabinoids vary among individuals. SOME of the reasons are: diet, age, health of the patient, and co-administered medications may impact metabolism and efficacy of cannabinoid-based products. Also, some patients have a genetic profile such that they are predisposed to experience side effects (for ex., exacerbation of a psychotic disorder/schizophrenia) after exposure to THC. In addition, patients that have been consuming cannabinoid-based products long-term react differently than patients who have never consumed cannabinoid-based products.

QUESTION: How should the cannabinoid-based therapy be withdrawn?

ANSWER: According to the Health Canada document entitled “Information for Health Care Professionals – Cannabis (marihuana, marijuana) and the Cannabinoids,” “If intolerable adverse effects appear without significant benefit, dosing should be tapered and stopped. Tapering guidelines have not been published, but the existence of a withdrawal syndrome suggests that tapering should be done slowly (i.e. over several days or weeks).” Note: When discontinuing cannabidiol therapies used for the treatment of seizure disorders, the dose should be decreased gradually. As with all antiepileptic drugs, abrupt discontinuation should be avoided when possible, to minimize the potential risk of increased seizure frequency and status epilepticus.

QUESTION: What are some of the more common reasons dermatologists recommend cannabinoid-based medicines?

ANSWER: According to the results of a survey of 145 dermatologists, 91 % of dermatologists were in support of medical cannabis use and 13.8 % have recommended it for a dermatologic condition. Atopic dermatitis (45 %) and psoriasis (40 %) were the most common. The most common form of administration was topical (75 %). The main reasons for not recommending medical cannabis were limited knowledge (56 %) and lack of experience (48 %).

QUESTION: Has the use of a transdermal gel for regional and systemic delivery of CBD been evaluated for the treatment of epilepsy?

ANSWER: Yes. A transdermal gel for regional and systemic delivery of CBD (Zynerba Pharmaceuticals) is in clinical development for treatment of epilepsy, developmental and epileptic encephalopathy, fragile-X syndrome, and osteoarthritis. NOTE: As of September 2021, the company’s website indicates that the product is not yet approved by government regulatory bodies, including the United States Food and Drug Administration (FDA) and other agencies, and must be tested to see if it is an effective and safe treatment.

QUESTION: Have human studies evaluated the effects of cannabinoid consumption on cortisol levels?

ANSWER: Yes – Human studies have demonstrated that the consumption of cannabinoids modulate cortisol release. Acutely, the consumption of cannabis (or THC) by naive or infrequent cannabis users may increase the secretion of cortisol. In chronic cannabis users, the stimulatory effect of THC on cortisol levels is blunted. This blunted response suggests that a tolerance develops. Some studies have reported that chronic cannabis users exhibit elevated basal cortisol levels, but that stress- induced activation of the axis is blunted in chronic adult and adolescent cannabis users.

QUESTION: Do endocannabinoids impact insulin release?

ANSWER: Yes. Endocannabinoids act in an autocrine and paracrine fashion to mediate the activity of the pancreas and mediate insulin secretion. – It has been shown that endocannabinoids influence basal as well as glucose-induced insulin release. Also, endocannabinoids have been shown to have an effect on β cell proliferation and survival. (Pancreatic β cells are the cells that synthesize and secrete insulin.)

QUESTION: Can children with developmental and epileptic encephalopathies tolerate adjunctive cannabidiol (CBD) transdermal gel, and is CBD gel associated with reduced seizure frequency?

ANSWER: Yes, CBD is well tolerated, and is associated with a reduction in seizure activity – frequency and intensity – in children, including improvements in alertness, energy, improved sleep, and in cognition or concentration. According to a JAMA Open Network article published in September 2021, in a “nonrandomized controlled trial, CBD transdermal gel was well tolerated over 6.5 months of treatment, with 60% of patients experiencing a treatment-related adverse event, 96% of which were mild or moderate. A 43.5% reduction in seizure frequency was observed in focal impaired awareness seizures and tonic-clonic seizures.” Also, the researchers stated that “Parents and caregivers noted improvements in social or interpersonal engagement and irritability (33 of 43 [77%] participants); alertness, energy, and sleep (23 of 43 [53%]); and cognition or concentration (20 of 43 [47%]).”

QUESTION: What influences chronic pain patients’ use of medical cannabinoids?

ANSWER: The British Medical Journal recently published results of a systematic review that explored values and preferences towards medical cannabis (MC) among people living with chronic pain. The results were as follows: “High to moderate certainty evidence showed that patient’s use of MC for chronic pain was influenced by both positive (eg, support from friends and family) and negative social factors (eg, stigma surrounding cannabis use). Most patients using MC favoured products with balanced ratios of THC and CBD, or high levels of CBD, but not high THC preparations. Many valued the effectiveness of MC for symptom management even when experiencing adverse events related to concentration, memory or fatigue. Reducing use of prescription medication was a motivating factor for use of MC, and concerns regarding addiction, losing control or acting strangely were disincentives. Out-of-pocket costs were a barrier, whereas legalisation of MC improved access and incentivised use.”

QUESTION: Do cannabinoids affect the male reproduction system?

ANSWER: Yes. Cannabinoid receptors are located in multiple parts of the male reproductive system, including the hypothalamus, pituitary, Leydig cells, and sperm. The binding of cannabinoids to cannabinoid 1 receptors may lead to a reduction in plasma testosterone, LH and FSH.

QUESTION: How does anandamide’s activation of CB1 receptors on sperm cells impact sperm cells?

ANSWER: Activation of CB1 receptors on sperm by anandamide – a fatty acid neurotransmiter endocannabinoid, or THC, leads to reduction of sperm survival and motility, and inhibition of fertilization capacity by hindering the capacitation-induced acrosome reaction needed to penetrate the zona pellucida.

QUESTION: How do endocannabinoids differ from many other neurotransmitters?

ANSWER: Endocannabinoids are very lipophilic and therefore cannot be stored in vesicles like many other neurotransmitters. The precursors of endocannabinoids are present in lipid membranes and, upon activation of some G-protein coupled receptors, these precursors are released into the extracellular space. Endocannabinoids are synthesized on demand in post-synaptic structures and travel retrograde through the synaptic cleft to cannabinoid type 1 receptors located presynaptically. Activation of cannabinoid type 1 receptors leads to inhibition of neurotransmitter release.

QUESTION: Polycystic ovarian syndrome (PCOS) is a syndrome associated with hyperandrogenism, menstrual irregularities, and polycystic ovaries. Is there any evidence that the endocannabinoid system is involved in the development of PCOS?

ANSWER: Yes. In a human study that evaluated the possibility of a link between the endocannabinoid system and PCOS, the researchers found that the endometrium of PCOS patients exhibited reduced levels of fatty acid amide hydrolase, (the catabolic enzyme for anandamide), compared to women without PCOS. This finding correlated with increased levels of anandamide in patients with PCOS. Also the activation of the ECS and overexpression of CB1 receptors may be associated with insulin resistance in women in PCOS.

QUESTION: When the endocannabinoid system was originally discovered in the 1990’s, it was described as a neural communication system. Does the endocannabinoid system have functions other than neural communication?

ANSWER: Yes. The endocannabinoid system can be found in almost every cell/ tissue and this system plays an important role in the normal functioning of many organ systems.

QUESTION: How do exogenous cannabinoids (phytocannabinoids or synthetic cannabinoids) affect physiologic systems like the endocrine system?

ANSWER: Exogenous cannabinoids bind to endogenous cannabinoid receptors in various organs, and may also modulate cannabinoid receptor expression. As a result, exogenous cannabinoids may alter endocannabinoid target effects and organ function.

QUESTION: True or false? Cannabinoid type 1 receptors are G-protein coupled receptors found in multiple organ systems, including the nervous system, skeletal system, lungs, cardiovascular system, musculoskeletal system, gi tract, and the lymph system, as well as in many endocrine organs, including the hypothalamus, pituitary, thyroid, adrenals, uterus, ovaries, testes, and placenta.

ANSWER: The statement is true, but the density and level of expression of cannabinoid receptors varies in the different organ systems.

QUESTION: On what cell surfaces are cannabinoid type 2 receptors typically found?

ANSWER: Cannabinoid type 2 receptors, like type 1 receptors, are G-protein coupled receptors; the type 2 receptors are primarily on the surface of the immune system cells, tonsils, the gi tract, bone, and peripheral nerve endings. Expression is highly inducible and is most often expressed when there is active inflammation or injury.

QUESTION: Does short term treatment with THC rich cannabis induce clinical remission and improve quality of life in patients with mild to moderately active ulcerative colitis?

ANSWER: Yes, according to a recent study. However, these beneficial clinical effects were NOT associated with significant anti-inflammatory improvement in the Mayo endoscopic score or laboratory markers for inflammation. These results were derived from a double-blind, randomized, placebo-controlled trial, – 32 patients received either cigarettes containing 0.5 g of dried cannabis flowers with 80mg THC or placebo cigarettes for 8 weeks. Parameters of disease including Lichtiger disease activity index, C reactive protein (CRP), calprotectin, Mayo endoscopic score and quality of life (QOL) were assessed before, during and after treatment.

QUESTION: Efficacy and safety of add-on cannabidiol (CBD) to treat seizures associated with Lennox Gastaut Syndrome (LGS) was demonstrated in two randomized controlled trials (RCTs). Have the long-term effects of CBD use to treat the drug resistant seizures of LGS been evaluated?

ANSWER: Yes. 366 patients enrolled in a long-term open-label extension trial. The results are as follows: “Adverse events (AEs) occurred in 96% of patients, serious AEs in 42%, and AE-related discontinuations in 12%. Common AEs were convulsion (39%), diarrhea (38%), pyrexia (34%), and somnolence (29%). Fifty-five (15%) patients experienced liver transaminase elevations more than three times the upper limit of normal; 40 (73%) were taking concomitant valproic acid. Median percent reductions from baseline ranged 48%–71% for drop seizures and 48%–68% for total seizures through 156 weeks. Across all 12-week visit windows, 87% or more of patients/caregivers reported improvement in the patient’s overall condition on the Subject/Caregiver Global Impression of Change scale.”

QUESTION: How does THC impact the gastro-intestinal system of a patient with IBD?

ANSWER: Cannabis might be a mediator within the gastrointestinal system, affecting inflammation, motility and the secretory response. Also, some cannabinoids increase appetite. A thorough 2021 review article summarized the current research evaluating the relationship between cannabinoid-based medicines and the treatment of IBD. A summary of their highlights include the following: “Patients with IBD often experience pain, nausea, and decreased appetite. As described here, in multiple studies, patients with IBD reported a significant improvement in symptoms and quality of life metrics with the use of cannabis. While initially promising, additional double-blind, placebo-controlled studies have found that even though CBD may improve perceived symptoms, it does not reduce inflammation or address underlying disease activity. These studies failed to demonstrate that when given cannabis, patients with IBD had an improvement in inflammatory markers [including CRP and calprotectin] or mucosal healing on endoscopy compared to patients with IBD in placebo conditions.”

QUESTION: Has the terpenoid caryophyllene, which is found in the cannabis plant, been found to significantly reduce craving to cigarettes?

ANSWER: Yes, according to one study with significant findings (P <0.01). Forty-eight cigarette smokers participated in a 3-h session conducted after deprivation from smoking overnight. The subjects were randomly assigned to one of three conditions: one group of smokers puffed on a device that delivered a vapor from essential oil of black pepper (black pepper contains caryophyllene); a second group puffed on the device with a mint/menthol cartridge, and a third group used a device containing an empty cartridge. Subjects puffed and inhaled ad libitum from the device throughout the session during which no smoking was allowed. Reported craving for cigarettes was significantly reduced in the pepper-containing device group relative to each of the two control conditions. Also, it was noted that negative affect and some somatic symptoms of anxiety were alleviated in the pepper-containing device group relative to the unflavored placebo. The authors suggested that one possible mechanism is via CB2 receptor agonism, with caryophyllene being a CB2R agonist.

QUESTION: CB1 receptors are abundant in the CNS, including areas involved in pain transmission. CB2 receptors are mostly located on peripheral tissues and immune cells. Are CB2 receptors involved with pain transmission?

ANSWER: Yes. When activated, CB2 receptors may modulate peripheral afferent pain fiber activity and immune-mediated neuro-inflammatory processes. For example, CB2 activation may lead to the inhibition of prostaglandin synthesis and/or mast cell degranulation; both of these cellular activities can precipitate and maintain chronic pain states.

They are actually produced on demand; they are synthesized from arachidonic acid of the membranes of post-synaptic neurons, and then they are released directly into the synapse and bind to receptors on the pre-synaptic neuron. In other words, they act in a retrograde fashion.

QUESTION: Some NFL players strongly believe that it’s safer for them to use marijuana to treat pain than to take prescription medication. What has the NFL done in response to this claim?

ANSWER: For years, the NFL suspended a player if the player tested positive for marijuana multiple times. That changed due to an agreement approved in 2020. Now, the pain management committee of the NFL and the NFL Players Association will provide $1 million in funding for research into pain management and cannabinoids. Specifically, the research is evaluating marijuana as a potential alternative to opioids. Also, the NFL is investigating how using cannabis-based products and CBD to treat pain affects performance in elite athletes.

QUESTION: A common adverse effect of chronic recreational marijuana use is cannabinoid hyperemesis syndrome. In fact, cannabinoid hyperemesis syndrome is a near daily diagnosis in many Canadian emergency departments. Anecdotal evidence supports the use of haloperidol to treat cannabinoid hyperemesis syndrome. Is haloperidol more effective than odansetron for the treatment of the nausea and vomiting associated with cannabinoid hyperemesis syndrome?

ANSWER: According to the results of a randomized controlled trial involving 33 patients with cannabinoid hyperemesis syndrome, haloperidol (0.05 mg/kg or 0.1 mg/kg) was superior to odansetron 8mg for average reduction from baseline in abdominal pain and nausea at 2 hours, and was associated with the need for fewer rescue antiemetics and shorter time to ED departure. In this study, there were 2 haloperidol and 6 ondansetron return ED visits for ongoing nausea/vomiting, as well as 2 return visits for acute dystonia, both in the higher dose haloperidol group.

QUESTION: Cannabinoids are metabolized by many of the same cytochrome P450 enzymes as warfarin. In fact, THC, CBD and CBN can inhibit the hydroxylation of warfarin, and thus lead to an increase in INR. Do cannabinoids also affect the metabolism of heparin? Is the metabolism of direct oral anticoagulants (DOACs), including rivaroxaban, edoxaban, and apixaban, impacted by cannabinoids?

ANSWER: While cannabinoids do not alter the metabolism of heparin, cannabinoids may impact the metabolism of DOACs. DOAC levels may increase, leading to an increased risk of bleeding.

QUESTION: Does CBD interact with receptors other than CB1 or CB2?

ANSWER: Yes. CBD has cannabinoid receptor-independent properties. For example, CBD is an agonist at the TRPV1 receptor and has agonist properties at the 5-HT1A/2A/3A serotonergic receptors. CBD is also a capsaicin analog. CBD has antagonist activity on alpha-1 adrenergic and μ-opioid receptors, too. In addition, CBD has been found to inhibit synaptosomal uptake of noradrenaline, dopamine, serotonin, and gamma-amino butyric acid. CBD also inhibits anandamide uptake.

QUESTION: Are cannabinoids an effective analgesic agent in the acute pain setting? Are cannabinoids an effective analgesic agent in the chronic pain setting?

ANSWER: According to the results of multiple randomized controlled trials examining the efficacy of cannabinoids to treat acute pain, THC, nabilone and other cannabinoid-based products were not associated with a reduction in pain, but were associated with adverse side effects, including sedation. In contrast to the lack of efficacy in the acute pain setting, cannabinoids are effective analgesic agents in the chronic pain setting. According to 2 systematic reviews involving a total of 29 randomized controlled trials (RCTs), 22 of the 29 RCTs demonstrated that cannabinoids do have a modest analgesic effect in the management of chronic pain.

QUESTION: What is the pharmacokinetic profile of marijuana when it is administered orally?

ANSWER: The psychoactive and physiological effects of orally consumed marijuana typically appear approximately 90 minutes after ingestion, reach their maximum after 2-3 hours and last for about 4-12 hours. However, there is a heterogeneous response to oral marijuana consumption and some individuals may not appreciate the peak effect until 6 hours after consumption.

QUESTION: Does marijuana affect appetite and metabolism?

ANSWER: Marijuana has been reported to stimulate appetite. There is a high concentration of CB1 receptors in the areas of the brain that control food intake and satiety, and these findings suggest that there is an association between marijuana consumption and appetite regulation. Additionally, studies suggest that the endocannabinoid system modulates taste sensation as well as the metabolism of lipids and glucose.

QUESTION: Does the dosing of cannabinoid-based drugs need to be adjusted for patients with hepatic disease?

ANSWER: Cannabinoids are metabolized by the liver and excreted through the GI tract and kidney. When considering cannabinoid therapy for patients with severe liver impairment, the dosage may need to be adjusted. For example, according to the prescribing information for an FDA-approved cannabidiol product, “dose adjustment is recommended in patients with moderate (Child-Pugh B) hepatic impairment or severe (Child-Pugh C) hepatic impairment. It may be necessary to have slower dose titration in patients with moderate or severe hepatic impairment than in patients without hepatic impairment. [This drug] does not require dose adjustment in patients with mild (Child-Pugh A) hepatic impairment.”

QUESTION: Does the endocannabinoid system modulate pain without the being triggered by THC or other phytocannabinoids?

ANSWER: Yes. Neural and non-neural cells of injured tissues produce endocannabinoids, including anandamide and 2-AG, and when these endocannabinoids activate the CB receptors, pain signals are modulated. Note: CB1 receptors are abundant in nociceptive and non-nociceptive sensory neurons of the dorsal root ganglion (DRG), the spinal cord, the brain, mast cells, macrophage defense cells, the trigeminal ganglion (TG), and epidermal keratinocytes. Few CB2 receptors are expressed in these regions, but the density of CB2 receptors increases when peripheral nerve damage occurs.

QUESTION: Other than via pills, capsules and liquid preparations, are there any other vehicles by which medical marijuana can be consumed orally?

ANSWER: In addition to pills, capsules and liquid preparations, medical marijuana can be consumed orally by ingesting marijuana-infused edibles, such as baked goods, candies, gummies, chocolates, lozenges, and beverages. It must be noted that the amounts of the various cannabinoids in edibles may not be consistent throughout a single baked product (a cookie, for example) or across a batch of baked products. As a result, it is difficult to estimate the amount of marijuana contained in each portion of edible product.

QUESTION: Do some cannabinoids reduce spasticity?

ANSWER: Studies have suggested that some cannabinoids effectively reduce the spasticity associated with multiple sclerosis, and, in fact, the federal drug agencies of several countries (but not the US) have approved a cannabinoid-based formula (50:50 THC:CBD) called Sativex (nabiximols) for the treatment of severe spasticity in multiple sclerosis. The cannabinoids act on the presynaptic CB1 receptors, and the receptor activation reduces massive glutamate release and regulates glutamatergic excitability during spasticity. The American Academy of Neurology proposes that the use of oral cannabinoid extracts or an oromucosal cannabinoid spray (1:1 THC:CBD) by MS patients may reduce symptoms of spasticity.

QUESTION: Is marijuana a sedative or stimulant?

ANSWER: Marijuana is a CNS depressant and may cause drowsiness or somnolence. Its CNS depressant effects are additive with other CNS depressants, including opioids. There is moderate evidence that marijuana or cannabinoids are effective for improving short-term sleep outcomes in individuals with sleep disturbance associated with obstructive sleep apnea syndrome, fibromyalgia, chronic pain, and multiple sclerosis.

QUESTION: What is the pharmacokinetic profile of marijuana when it is smoked?

ANSWER: When herbal marijuana is smoked via a cigarette or a pipe, THC, CBD and other phytocannabinoids, as well as terpenoids, are vaporized by the heat of combustion and inhaled. Inhaled constituents quickly pass from alveoli into the bloodstream and readily cross the blood-brain barrier. CNS effects appear within seconds to a few minutes of inhalation, reach a maximum after 15-30 minutes, and taper off within 2-3 hours. It must be noted that the amounts of cannabinoids consumed are, in part, dependent upon the patient’s inhalation techniques, including the quality and efficiency of inhalation, duration of inhalation, and spacing of inhalations.

QUESTION: THC and CBD have significantly different receptor binding capacities, and thus different pharmacological effects. Are the differences in binding capacity due to different chemical compositions?

ANSWER: THC and CBD actually have the same chemical formula, C21H30O2. They are structural isomers. The key structural difference between the two molecules is that there is an oxygen-containing closed ring in THC that is open in CBD. This one structural difference leads to significantly different receptor binding capacities and thus different pharmacological effects of the two substances.

QUESTION: What is Rick Simpson oil (aka RSO)?

ANSWER: Solvent-based concentrates are made by extraction of the plant matter with chemical solvents. In this method, cannabis is soaked in the solvent and then the cannabis is removed by straining. Then, the solvent is boiled off, and a sticky cannabis resin remains. These extracts are often a very dark color (green to black) and contain residuals from the solvents used. These products are sometimes referred to as Rick Simpson Oil (RSO), named after the individual that made this type of extraction popular.

–––

QUESTION: Some people consume cannabinoids via “dabbing.” Describe this method of consumption.

ANSWER: Basically, with dabbing, a cannabis concentrate is applied to a hot platform and the cannabinoids are volatilized. The vapor then passes through a water-pipe device and is inhaled by the consumer. The hot platform (commonly called “the nail”) is usually constructed from quartz, ceramic or titanium. This nail is heated, often with a blow torch, and after the nail is hot, a small amount of cannabis concentrate is applied. Vaporization of the cannabinoids is immediate. Inhalation by the consumer during application of the cannabis concentrate draws the vapors from around the nail into the water pipe.

–––

QUESTION: Other than butane, what are some of the chemical solvents used to create cannabis concentrates? Other than using solvents to create cannabis concentrates, what other methods to produce cannabis concentrates can be used?

ANSWER: Hexane, isopentane, isopropyl alcohol, acetone, and propane are used to make cannabis concentrates. In addition to using solvents, concentrates can also be manufactured via a dry method, a water-based method or a CO2 based method.

–––

QUESTION: Do all medical marijuana legal states allow the sale of products manufactured through butane extraction and supercritical CO2 extraction?

ANSWER: Supercritical CO2 extraction does not leave residual hydrocarbons, while butane extraction does. As a result, some states will allow the sale of supercritical CO2 extraction products, but not allow the sale of butane extracts.

–––

QUESTION: In addition to butane extraction, supercritical CO2 extraction is another process used to manufacture cannabis extracts. What is the major difference in the end products of the two processes?

ANSWER: Supercritical CO2 extraction does not leave any trace of hydrocarbon solvents in the end product, while butane extraction does. The viscosity of the supercritical CO2 products is less than the viscosity of the butane extraction products. As a result of a lower viscosity, supercritical CO2 extraction process products can be used in vaporizer pens on its own without cutting agents. While products derived from a butane extraction are used in dabbing, products derived from supercritical CO2 extraction are not.

–––

QUESTION: Some patients may use shatter, budder, crumble, pull-and-snap, and/or wax. Are all of these products exactly the same?

ANSWER: All of these products are cannabis extracts, but it is the specific manufacturing/ processing of the hash oil cannabis products that will determine the consistency of the product. Depending upon the consistency and other physical characteristics, the product will be called shatter, budder, crumble, pull-and-snap or wax.

QUESTION: Does short term treatment with THC rich cannabis induce clinical remission and improve quality of life in patients with mild to moderately active ulcerative colitis?

ANSWER: Yes, according to a recent study. However, these beneficial clinical effects were not associated with significant anti-inflammatory improvement in the Mayo endoscopic score or laboratory markers for inflammation. These results were derived from a double-blind, randomized, placebo-controlled trial, – 32 patients received either cigarettes containing 0.5 g of dried cannabis flowers with 80mg THC or placebo cigarettes for 8 weeks. Parameters of disease including Lichtiger disease activity index, C reactive protein (CRP), calprotectin, Mayo endoscopic score and quality of life (QOL) were assessed before, during and after treatment.

QUESTION: The amounts of marijuana in a joint, blunt, spliff or bowl are not standardized. How does a clinician estimate the amount of marijuana being used by the patient?

ANSWER: When trying to assess the quantity of marijuana consumed by a patient, multiple questions should be addressed, including: how often and how much the patient typically purchases, how many bowls (or joints, or blunts or spliffs) the patient smokes each time he consumes marijuana, and how many times he uses marijuana before he needs to purchase again. It must be noted that the total amount of cannabinoids present in marijuana is not equal to the amount that is ingested. (when smoking, an individual typically absorbs about 25% of the cannabinoids present in herbal marijuana mixture.) Also, the concentration of the cannabis-based product must be considered, as well.

QUESTION: In patients 60 years old or older, does long term (3 months) marijuana use impact blood pressure?

ANSWER: According to a recent study that was published in the European Journal of Internal Medicine, amongst adults 60 years or older with hypertension, marijuana treatment for 3 months was associated with a reduction in 24-hours systolic and diastolic blood pressure. At 3 months follow-up, the mean 24-hours systolic and diastolic blood pressures were reduced by 5.0 mmHg and 4.5 mmHg, respectively (p<0.001 for both). The nadir for the blood pressure and heart rate was achieved at 3 hours post-administration. The proportion of normal dippers changed from 27.3% before treatment to 45.5% afterward. No significant changes were seen in the different metabolic parameters assessed by blood tests, anthropometric measurements, or ECG exam.

QUESTION: What is the purpose of urine drug testing?

ANSWER: Urine drug tests typically screen for the patient’s prescribed opioids and the commonly abused drugs: cocaine, amphetamines, alcohol, barbiturates, opiates and benzodiazepines. Although a urine drug test can confirm if the patient is taking the prescribed opioid, it cannot determine if the patient is taking the prescribed dose.

–––

QUESTION: What are the drugs that are inhibitors to cytochrome P450 and therefore decrease the metabolism of cannabinoids?

ANSWER: THC is oxidized by the cytochrome P450 (CYP) mixed-function oxidases 2C9, 2C19 and 3A4 1. Therefore, substances that inhibit these CYP isoenzymes (e.g. fluoxetine, cimetidine, clarithromycin, ketoconazole, verapamil, indinavir, among others) can potentially increase the bioavailability of THC, and thus increase the chance of experiencing THC-related side effects.

–––

QUESTION: Why do NSAIDS relieve pain?

ANSWER: NSAIDs reduce the production of prostaglandin E2 (PGE2) and prostacyclin (PGI2), which mediate pain and inflammation.

–––

QUESTION: Describe the process of vaporization of cannabis.

ANSWER: Vaporization is a smokeless delivery system in which warm air or heat of 180°C to 200°C, rather than a flame, is used to convert cannabinoids and other compounds into a fine mist that can be inhaled. Due to their volatility, cannabinoids will vaporize at temperatures of 180°C to 200°C, but will not combust and therefore few combustion by-products such as soot or polycyclic aromatic hydrocarbons are produced. As temperatures increase, the amount of cannabinoids released increases, and the amount of combustion by-products increases, too.

–––

QUESTION: The pharmacological properties of cannabigerol have been investigated. What have the studies shown?

ANSWER: Cannabigerol (CBG) is the phytocannabinoid precursor molecule, and demonstrates weak partial agonism at CB1 and CB2. In in vitro studies, CBG displays analgesic and anti-erythemic effects. CBG also displays anti-hypertensive activity.

–––

QUESTION: The pharmacological properties of tetrahydrocannabivarin have been investigated. What have the studies shown?

ANSWER: Tetrahydrocannabivarin (THCV) is a CB1 antagonist at low doses, but displays weak agonistic effects at high doses. In obese mice models, THCV reduced appetite, produced weight loss and decreased body fat and leptin concentration.

–––

QUESTION: What is the pharmacologic profile of cannabis when it is vaporized?

ANSWER: The pharmacologic profile of cannabis when it is vaporized is similar to the profile when it is smoked. Psychoactive effects appear within 90 seconds, reach a maximum after 15-30 minutes, and taper off within 2-3 hours.

–––

QUESTION: What is the pharmacologic profile of cannabis when it is smoked?

ANSWER: When herbal cannabis is smoked, the active ingredients in cannabis are vaporized by the heat of combustion and inhaled. Inhaled constituents quickly pass from alveoli into the bloodstream and readily cross the blood-brain barrier. Psychoactive effects appear within 90 seconds, reach a maximum after 15-30 minutes, and taper off within 2-3 hours. This short onset of action makes dose titration possible, by spacing inhalations at 90-second intervals.

–––

QUESTION: The pharmacological properties of cannabichromene have been investigated. What have the studies shown?

ANSWER: Cannabichromene (CBC) is a potent anadamide uptake inhibitor and thus may modulate the endocannabinoid system similarly to CBD. In mice studies, it has been shown that CBC has anti-inflammatory properties and analgesic activity. CBC has other pharmacological properties, as well.

–––

QUESTION: The pharmacological properties of cannabinol have been investigated. What have the studies shown?

ANSWER: Cannabinol (CBN) is the oxidative by-product of THC and appears after long storage. It is a weaker partial agonist at CB1 and CB2 as compared to THC. In in vitro studies, it has been found that cannabinol is anticonvulsant and anti-inflammatory, and stimulates bone formation.

–––

QUESTION: It is the mixture of phytocannabinoids, terpenes and other active components present in a cannabis product that ultimately determines the therapeutic effects and side effects. Does CBD affect THC absorption and tolerance?

ANSWER: CBD has long been thought to influence the effects of THC. This thinking was extended to consider that CBD potentiates some of the beneficial effects of THC, as it reduces the psychoactive effects of THC and thus could improve tolerability. CBD may counteract some of the functional consequences of CB1 receptor activation in the brain. This effect has been used to explain why high CBD:THC cannabis use is less associated with the development of psychotic symptoms compared to low CBD:THC cannabis. Also, CBD is thought to interact with the cytochrome p450 enzymes that metabolize THC and thus may alter the metabolism and influence the effects of the THC consumed. It has been proposed that THC and CBD act synergistically in therapeutic use.

–––

QUESTION: Does methadone alter cardiac conduction?

ANSWER: Yes. Methadone is known to prolong QTc intervals in up to 16% of patients. Studies have shown a linear dose response curve, with higher doses leading to a higher propensity for QTc prolongation. This has led to an FDA “black box” warning for methadone and the recommendation for routine ECG monitoring.

–––

QUESTION: How have medical advances altered opioid use in cancer patients?

ANSWER: Cancer is no longer considered a “terminal disease.” Because of significant advances in surgical, radiation, and chemotherapeutic treatments, more than 50% of cancer patients are living greater than 2 years after the diagnosis of cancer. This allows for more cancer patients to develop chronic pain. All of these factors have led to more cancer patients taking opioids long-term.

–––

QUESTION: What are terpenes (or terpenoids)?

ANSWER: Terpenes are aromatic components produced in the glandular part of the cannabis plant’s flower bud. Terpenes are manufactured by many plants (not just the cannabis plant) and can be found in many food products, including coffee beans, ginger and cinnamon. Often, it is the terpenes that are responsible for a plant’s odor.

–––

QUESTION: Does smoking marijuana impact the metabolism of theophylline?

ANSWER: It may. Reports have indicated that smoking marijuana may increase the clearance of theophylline. Note: this effect appears to be a direct result of the hydrocarbons found in marijuana smoke rather than the cannabis-based products, as there is a lack of evidence for enzyme induction when cannabis-based drugs are consumed via oral ingestion.

–––

QUESTION: Do the hydrocarbons in marijuana smoke impact drug metabolism?

ANSWER: Possibly. Similar to cigarette smoke, the hydrocarbons in marijuana smoke appear to induce the activity of some cytochromes, including CYP1A2.

QUESTION: The International Association for the Study of Pain (IASP) has updated the definition of pain. What is their new definition of pain?

ANSWER: After 40+ years, the IASP has revised their definition of pain to reflect advances in our understanding of pain. The revised definition emphasizes that tissue damage is not required. The updated definition of pain is: “An unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage.” The revised definition also includes 6 notes:
1.) Pain is always a personal experience that is influenced to varying degrees by biological, psychological, and social factors
2.) Pain and nociception are different phenomena, and pain cannot be inferred solely from activity in sensory neurons
3.) Through life experiences, people learn the concept of pain
4.) A person’s report of an experience as pain should be respected
5.) Although pain usually serves an adaptive role, it may have adverse effects on function and social and psychological well-being
6.) Verbal description is only one of several behaviors to express pain, and an inability to communicate does not negate the possibility that a human or a nonhuman animal experiences pain

QUESTION: Rohypnol® is the trade name for the benzodiazepine called unitrazepam. Has this drug ever been approved by the Food and Drug Administration for medical use in the United States?

ANSWER: No, but outside the US, Rohypnol® is prescribed to treat insomnia. Rohypnol® has been referred to as a date rape drug or roofies. Before 1997, Rohypnol® was manufactured as a white tablet, and when mixed in liquids, it was colorless, tasteless, and odorless. In 1997, the manufacturer responded to concerns about the drug’s role in sexual assaults, and reformulated the drug. Now, Rohypnol® is produced as an olive green tablet with a speckled blue core that when dissolved in light-colored drinks will change the color of the liquid to blue. Of note, generic versions of the drug may not contain the blue dye.

QUESTION: Cannabinoids are metabolized by many of the same cytochrome P450 enzymes as warfarin, including CYP3A4, CYP2C9, and CYP2C19. THC, CBD and CBN can inhibit the CYP2C9-mediated hydroxylation of warfarin, and thus lead to an increase in INR. Do cannabinoids also affect the metabolism of heparin? Is the metabolism of direct oral anticoagulants (DOACs), including rivaroxaban, edoxaban, and apixaban, impacted by cannabinoids?

ANSWER: While cannabinoids do not alter the metabolism of heparin, cannabinoids may impact the metabolism of DOACs. DOACs are substrates of P-gp and are absorbed by the gut through the P-gp efflux transporter. Cannabinoids may bind to P-gp membrane transporters and alter DOAC metabolism. DOAC levels may increase, leading to an increased risk of bleeding.

–––

QUESTION: CBD is a CB1 antagonist and a negative allosteric modulator at CB2. Does CBD interact with receptors other than CB1 or CB2?

–––

QUESTION: How do cannabinoids modulate pain sensation? In other words, describe the mechanism of action of cannabinoids.

ANSWER: Endocannabinoids are synthesized in the postsynaptic neuron in response to stimuli such as pain, stress and inflammation. Endocannabinoids travel in a retrograde fashion and activate the presynaptic CB receptors. Antinociceptive effects occur when either endocannabinoids or phytocannabinoids activate presynaptic inhibitory CB1 receptors. Stimulation of CB1 receptors (G protein coupled receptors (Gi,Go)) leads to a reduction of cAMP production via the inhibition of adenylyl cyclase. This results in an action on voltage gated calcium and potassium channels – there is a depression of neuronal excitability and a reduction of neurotransmitter release.

–––

QUESTION: A study by Jamal et al. published in the European Journal of Anaesthesiology reported that marijuana users required a higher dose of morphine s/p abdominal surgery. They estimated that there was a 23% increased opioid dose requirement. Have the results of studies examining the opioid requirements s/p orthopedic surgery also shown that marijuana users require more opioids than patients who do not use marijuana?

ANSWER: In a retrospective study including 3793 patients, patient-reported postoperative outcomes of 155 marijuana users were compared with those of 155 non-users. The results indicate that pre-operative marijuana users had higher pain scores at rest and on movement but did not consume more post-operative opioid analgesics. The cannabinoid users also reported a greater incidence of post-operative sleep impairment.

–––

QUESTION: CBD is a negative allosteric modulator. What does that mean?

ANSWER: A negative allosteric modulator changes the shape of the receptor and, as a result, reduces the binding ability of components that typically bind to the receptor. In the case of cannabinoids, CBD alters the shape of CB1 receptors, and THC along with endogenous cannabinoids do not bind to the CB1 receptor to the same degree as they do when CBD is not present.

–––

QUESTION: Some producers of cannabinoid products will provide a Certificate Of Analysis (CoA) from an independent certified testing laboratory. What information is typically displayed on a CoA?

–––

QUESTION: What are the precursors for the most commonly naturally occurring phytocannabinoids?

ANSWER: The precursors for THC, CBD and CBC are olivetolic acid and geranyl pyrophosphate. These precursors undergo a condensation reaction which results in the formation of cannabigerolic acid (CBGA). A cyclase enzyme converts CBGA into either tetrahydrocannabinolic acid (THCA) or cannabidiolic acid (CBDA) or cannabichromenic acid (CBCA). Then, heat decarboxylates these cannabinoids into THC, CBD or CBC, respectively.

–––

QUESTION: True or false? Cannabinoids impact NMDA, opioid AND gamma amino butyric acid (GABA) receptors.

ANSWER: True. Not only do cannabinoids act at NMDA, opioid AND gamma amino butyric acid (GABA) receptors, but they also have activity at receptors such as adenosine, serotonergic, adrenergic, nicotinic acetylcholine, glycine, and PPAR receptors, and ion channels such as TRPV.

QUESTION: How do cannabinoids modulate pain sensation? In other words, describe the mode of action of cannabinoids.

ANSWER: The endocannabinoid system, consisting of the cannabinoid₁ receptor (CB₁R) and cannabinoid₂ receptor (CB₂R), endogenous cannabinoid ligands (endocannabinoids), and metabolizing enzymes, is present throughout the pain pathways. Endocannabinoids, phytocannabinoids, and synthetic cannabinoid receptor agonists have antinociceptive effects in animal models of acute, inflammatory, and neuropathic pain. CB₁R and CB₂R located at peripheral, spinal, or supraspinal sites are important targets mediating these antinociceptive effects. The mechanisms underlying the analgesic effects of cannabinoids likely include inhibition of presynaptic neurotransmitter and neuropeptide release, modulation of postsynaptic neuronal excitability, activation of the descending inhibitory pain pathway, and reductions in neuroinflammatory signaling. The large body of preclinical evidence in support of cannabinoids as potential analgesic agents is supported by clinical studies demonstrating their efficacy across a variety of pain disorders.

—

QUESTION: EXPERIMENTAL pain studies indicate that cannabinoids may be an effective therapy for acute and chronic pain. Have the results of CLINICAL studies also shown that cannabinoids are effective at alleviating acute and chronic pain?

ANSWER: In contrast to experimental studies, the results of clinical trials with cannabinoids provide only moderate-quality evidence for the relief of chronic pain. Also, the analgesic effects of cannabinoids have not been found to be superior to placebo in acute pain. In addition, pre-operative and peri-operative marijuana use may increase post-operative perceived pain.

Milk… it STILL does a body good!

Food color.

What a compelling subject, eh?

Doubtless, it’s a spell-binding topic, and certainly one bound to keep readers’ rapt attention!

Thrilling and exciting!

Compelling even!

Except that, things aren’t always what they seem.

First, however, you’ll need to be buttered up for this one.

In an unobtrusive article cross-published in Smithsonian Magazine (also at https://www.ZocaloPublicSquare.org/2020/01/15/when-the-government-decided-the-spread-on-your-toast-should-be-pink/ideas/essay/), author Ai Hisano addresses food color.

Instead of being professionally prepared as a chef, restaurateur, food historian, or nutritional anthropologist, author Ai Hisano is Senior Lecturer at the Graduate School of Economics at Kyoto University, Japan, and has been the Newcomen Postdoctoral Fellow in Business History at Harvard Business School, where she most recently authored Visualizing Taste: How Business Changed the Look of What You Eat.

Though her article isn’t difficult to swallow, it was rather bland and under-cooked, because while she did the job fairly well enough sharing some interesting tid-bit details about the history of oleomargarine, she failed overall to address the underlying concern – and therefore the premise of – the rationale for the existence of laws regulating the color of oleomargarine.

Again,
the unspoken and underlying concern
for the color of margarine
– the question
‟Why was it a concern?〞
–  failed to be addressed.

That concern is fraud.

Sadly, food fraud remains a concern today – even in the United States.

For example, producers of plant-based non-dairy imitation milk products such as “almond milk” are rapidly being caught in the cross hairs of public intrigue with their highly-processed, made-in-a-chemistry laboratory pseudo-natural products by making numerous varieties of claims about their product(s), none of which are proven, nor represent any improvement in public health, though their marketing obliquely intimates as much.

It is inherently fraudulent to label a product as being a certain thing when it is not.

That is plain and simple.

And I write this with all sincerity: It makes me

Scandalous!!

Reproduction of an original photograph of Prince George of Greece and Denmark (1869-1957) and Princess Marie Bonaparte (1882-1962). Prince George is sitting to the right wearing military uniform. Princess Marie is standing beside him to the left with her right hand resting on her hip. She is wearing a pale coloured dress and strings of pearls. There is a wooden wall behind them. The photograph is signed and dated. Prince George of Greece and Denmark was the second son of George I, King of the Hellenes. Princess Marie Bonaparte was a descendant of Emperor Napoleon I, an heiress and a psychoanalyst. They married in 1907.

Identify the TRUE statements about Marie Bonaparte (1882-1962), great grand-niece of Emperor Napoleon:

1.) Was anorgasmic.

2.) Was a psychoanalyst.

3.) Helped advance

Why Should I Get The Flu Vaccine?

People that say ‘don’t get the flu vaccine because it’ll give you the flu’ are the equivalent of those who say ‘don’t eat an egg, because you might grow a chicken.’

There’s nothing in the vaccine that can cause influenza.

It’s not even a live vaccine.

It’d sure look funny with a chicken thigh coming out of your ear.

And, there’s no telling where the head and wing would pop up!🤪😂

There’s a “teachable moment” in that bit of humor for those who are “anti-vaxxers.”

You know… just in the case you happen to meet any.

Science: It’s like gravity.

You don’t have to “believe in it” for it to work.
It’s a FACT.

To obtain the fullest immunity from the vaccination takes at least TWO WEEKS for one’s body to build up antibodies to the virus… which is NOT in the vaccine.

“Take Back” Our Schools, Government, and Teach Mythology

For the record, while I receive their emailings, I have NEVER been a part of, nor have I EVER in any way supported the Family Resource Council. The reason I receive them is because it’s always good to know what kind of shenanigans your adversaries are up to. And, I’ve marveled, and continue to do marvel, at their, and other right-wingers’ “take back” this-that-or-the-other diatribes. The only problem with that is that they never say how far back they want to take whatever it is they want to steal. Before 18-year-olds had the right to vote? Before the Civil Rights Act? Before Women’s Suffrage? Before Alabama became the 27th state to ratify the 13th Amendment which outlawed slavery? How far back? They never say.

But you see, by creating an “Us vs Them” mentality, they immediately establish a simplistic either/or “we’re the ‘good guys,’ and you’re the ‘bad guys'” mind set, which then also allows them to couch their the language of their argument as if some evil adversary stole something from them, i.e., “take back.”

How can anyone “steal” public schools? Steal from them by denying tax dollars, or funnel tax dollars to private corporations, I can see. But “steal” them? Hardly possible. Of course, that has never been the case – nor will it ever be the case – because no one stole anything.

Unfortunately, we also see that fallacious and petty mindset in politics, as in

16-Year Study: Medical Marijuana Laws Decrease Underage Use

Results of a large-scale, 16-year anonymized research project found that states with Medical Marijuana Laws (MMLs) and decriminalization statutes, underage cannabis consumption declines, especially among minority youth.

One concern some have regarding legalization of cannabis – whether for Medical (MMJ), or Adult Recreational Use (ARU) – is whether or not it will adversely affect youth. Specifically, a question often asked is, “will legalizing cannabis increase underage consumption?”

Lead Researcher Dr Rebekah Levine Coley said that, “Some people have argued that decriminalizing or legalizing medical marijuana could increase cannabis use amongst young people, either by making it easier for them to access, or by making it seem less harmful.”

“However, we saw the opposite effect,” said Dr Coley, and noted that results of the 16-year-long study show that in states where MMJ is legal, rates of underage consumption of cannabis have declined.

Those findings occurred even after accounting for other variables, including policies on

Teen Grey Matter and Cannabis Use

In a recently published article entitled “Grey Matter Volume Differences Associated with Extremely Low Levels of Cannabis Use in Adolescence,” in the Journal of Neuroscience, 14 January 2019 edition, pp3375-17, researchers wrote in part that “We identified extensive regions in the bilateral medial temporal lobes as well as the bilateral posterior cingulate, lingual gyri, and cerebellum that showed greater GMV in the cannabis users.”

News items related to that newly published research are focusing upon that singular line as if it’s something negative. Since when did INCREASED grey matter become something dangerous, or cause for concern? Colloquially, the term “grey matter” is used to describe the brain, and by extension, brain power. So let’s examine this matter (no pun intended) in more detail.

But before proceeding further, it bears mentioning that adolescents should NOT be consuming cannabis, neither alcohol, nor tobacco. And try as much as we want, we will not ever stop underage consumption of any adults-only substance. The BEST we can do is to educate them, and others, of potential risks involved in its use – especially and particularly underage use – and deny them opportunities to consume alcohol, tobacco, and cannabis. THAT is a strategy which has PROVEN to work, because the trite “Just say ‘no'” has never worked, nor will it ever.

Dr David Robert Grimes is a physicist, cancer researcher and science writer, who was the joint recipient of the 2014 Nature / Sense About Science Maddox Prize and wrote in a brief anti-marijuana article dated 15th May 2017 entitled “The rise of the cannabis cult: don’t believe the hype about medical marijuana” that

Dream A Little Dream Of Me: How Dreams Reflect, And Guide Our Waking Lives

Dreams are a world of surreality, where anything can, and does, happen.

In our dreams, pigs can fly, cats bark, and trees can speak. But more importantly than the seeming peculiarities such as talking telephone poles, or growing houses, is the symbolism of the objects in the dreams. One thing stands for another.

In our dreams, snakes might not necessarily represent the animal, but may represent deception, or danger. Conversely, depending upon the context of the dream, snakes may represent sexuality, or even money. It is the combination of the context of the elements in the dream, their setting, and actions, in conjunction with the events of our waking lives, that may provide useful information, even unique insight, into our waking lives.

Dreams can be thought of a type of guide to our waking lives, because they often reflect what is occurring, sometimes even with imperceptible events occurring behind the scenes, of which we are naturally unaware.

And, our dreams may also forewarn us of events. For example, in the Scriptural account in the Gospel of Matthew, the Magi, popularly called the “Three Wise Men” (though no translation of the story specifies how many there were) who had come to visit the exiled Holy Couple – Joseph, Mary, and the newborn Jesus, who had similarly been warned in a dream to flee their homeland before the child’s birth – returned to their homeland after their visit, because they were warned in a dream to do so. In chapter 2, verse 12 it states that, “And having been warned in a dream not to go back to Herod, they returned to their country by another route.” (NIV)

The narrative doesn’t say what they dreamed, or the elements those dreams contained, it merely states that they used perceptive insight (were cognizant of significance) given to them while (presumably) in a state of unconsciousness – sleep. In other words, their dreams, as they interpreted, provided useful information to give them, giving meaning (and safety) to their lives at a time of unknown peril.

Trump is President. What could possibly go wrong? Could the Electrical Power Grid go down? Ask NIST.

If the GOP and POTUS have their way, your cell phone GPS, cell phone clock, Internet clock, atomic clock, communication satellites, and countless other devices reliant upon accurate timekeeping which are not even owned by you could go awry. Even our power grid could suffer.

Why?

First, some background.

The National Institute of Standards and Technology (NIST) has for many years operated our national Atomic Clock. In fact, in 2014 they “launched a new atomic clock, called NIST-F2, to serve as a new U.S. civilian time and frequency standard, along with the current NIST-F1 standard.”

National Academies #Marijuana Findings @theNASEM

Many have heard or read about United States Attorney General Jeff Sessions’ ignorant remark about marijuana, and many of us have heard or read numerous claims about cannabis, ranging from “it cures cancer” to “it makes you hungry,” and almost everything between. But if you want to make an effective argument for or against anything, you need facts. And the following information from the National Academies of Sciences, Engineering, and Medicine is THE MOST authoritative, up-to-date volume on the subject of cannabis. You would be wise to cite this research when you lobby your local, state or national legislator to legalize (or not) marijuana. (I am a legalization proponent & advocate for the 100% legalization, regulation, and taxation of adult recreational & prescriptive medical use of marijuana.)

Now, with the 2017 release of “The Health Effects of Cannabis and Cannabinoids: The Current State of Evidence and Recommendations for Research” by the Committee on the Health Effects of Marijuana: An Evidence Review and Research Agenda, Board on Population Health and Public Health Practice Health and Medicine Division, A Report of the National Academies of Science, we have one of THE MOST to-date conclusive pieces of EVIDENCE for/against cannabis consumption, either medically, and/or recreationally. It is AUTHORITATIVE, and unbiased. Bear in mind, this is findings of SCIENTIFIC MEDICAL RESEARCH.

An independent examination of the report was carried out in accordance with institutional procedures and all review comments were carefully considered. A committee of experts was convened to conduct a comprehensive review of the literature regarding the health effects of using cannabis and/or its constituents that had appeared since the publication of the 1999 IOM (Institute of Medicine) report.

From their review, the committee arrived at nearly 100 different research conclusions related to cannabis or cannabinoid use and health.

Committee members formulated four recommendations to address research gaps, improve research quality, improve surveillance capacity, and address research barriers.

Categories, including subtopics, are as follows:

Therapeutic effects
• Chronic pain; cancer, chemotherapy-induced nausea/vomiting; anorexia and weight loss; irritable bowel syndrome; epilepsy; spasticity related to multiple sclerosis or spinal cord injury; Tourette syndrome; amyotrophic lateral sclerosis; Huntington’s disease; Parkinson’s disease; dystonia; dementia; glaucoma; traumatic brain injury; addiction; anxiety; depression; sleep disorders; post-traumatic stress disorder; schizophrenia and other psychoses

Cancer
• Lung cancer; head and neck cancer; testicular cancer; esophageal cancer; other cancer

Cardiometabolic risk
• Acute myocardial infarction; stroke; metabolic dysregulation, metabolic syndrome, prediabetes, and diabetes mellitus

Respiratory disease
• Pulmonary function; chronic obstructive pulmonary disorder; respiratory symptoms (including chronic bronchitis); asthma

Immunity
• Immune function; infectious disease

Injury and death
• All-cause mortality; occupational injury; motor vehicle crash; overdose injury and death

Prenatal, perinatal, and postnatal exposure to cannabis
• Pregnancy complications for the mother; fetal growth and development; neonatal conditions; later outcomes for the infant

Psychosocial
• Cognition (learning, memory, attention, intelligence); academic achievement and educational outcomes; employment and income; social relation- ships and other social roles

Mental health
• Schizophrenia and other psychoses; bipolar disorders, depression; suicide; anxiety; post-traumatic stress disorder

Problem cannabis use
• Cannabis use disorder

Cannabis use and abuse of other substances
• Abuse of other substances

Weight Of Evidence Categories for Conclusions are ranked High-to-Low-and-None as Substantial, Moderate, Limited Evidence, and No or Insufficient Evidence to Support the Association for therapeutic effects, and other health effects.

Here are: 
Conclusions—Therapeutic Effects of Cannabis and Cannabinoids

Authoritative Evidence That @TheJusticeDepartment AG @JeffSessions Is Wrong About #Cannabis

“I am astonished to hear people suggest that we can solve our heroin crisis by legalizing marijuana – so people can trade one life-wrecking dependency for another that’s only slightly less awful.”

–United States Attorney General Jeff Sessions, prepared remarks on “Efforts to Combat Violent Crime and Restore Public Safety Before Federal, State and Local Law Enforcement” in Richmond, VA, Wednesday, March 15, 2017

Many have heard or read about US Attorney General Jeff Sessions’ other willfully ignorant remarks about marijuana, such as his testimony before the Senate Judiciary Committee when he was then-president Reagan’s first federal judicial nominee to be rejected:

“I thought those guys [the Ku Klux Klan] were OK until I learned they smoked pot.”
-Jeff Sessions, nominee of then-President Ronald Reagan as Federal Judge of the U.S. District Court for the Southern District of Alabama, to Senate Judiciary Committee, June 1986

The Senate Judiciary Committee rejected on June 5, 1986 the nomination of Jefferson B. Sessions, III to be a Federal District Judge in Alabama. It was the first time one of President Reagan’s judicial nominees was rejected.

In 1986, the Senate Judiciary Committee heard testimony about Jeff Sessions from 21 witnesses over 19 hours, including from Thomas Figures, a Black Assistant U.S. Attorney who had worked with Sessions, and testified that Jeff Sessions had made that remark, and other racist comments to him while Sessions was serving as United States Attorney in Mobile, AL. Sessions denied making racial statements, but Republican and Democratic senators expressed concern over his attitude toward members of minority groups, and especially Sessions’ prosecution of three Blacks who were eventually acquitted on charges of voting fraud.

The Senate Judiciary Committee voted 10-8 against Jeff Sessions’ nomination in June 1986, which made him

Want More #Sex? Smoke More #Cannabis!

NPR recently reported about research that seems to point to one benefit of daily use of cannabis.

Increased sexual activity.

I continue to maintain that:
a.) People NEED & OUGHT to have MORE SEX, and;
b.) Cannabis NEEDS & OUGHT to be legalized, taxed & regulated.

Because:
a.) No one ever had an orgasm while “mad” or “angry,” and;
b.) I’ve neither read nor heard of anyone being “mad” or “angry” while high.

Fact is, research is continuing to show that increasingly, people are ANGRY at/because of many things, some of which are outside the locus of their immediate control, and that correspondingly, people are having sexual encounters less often – including married couples (for the benefit of those who believe that sexual activity belongs only among married couples). STOP ANGER! Get high! Have sex!

There’s SIGNIFICANTLY MORE argument to be made AGAINST ETOH (ethanol alcohol, aka “beverage” alcohol) than against cannabis.

Research: For Older Adults To Get Smarter, They Should Have More Sex

Research Shows Sex Is Good For Your Brain, Cognitive Function & Mental Health

So, Are You Fucking Smarter Every Fucking Day?

Maybe. 

Could you be fucking stupid? If you are, then stop. Fuck someone smarter.

But, there’s a catch.

Fucking stupid may be good for your AND your partner’s brain. So fucking stupid might not be so fucking stupid.

Perhaps that may explain why some people in America are so fucking stupid. They’re not fucking. Hence, they’re fucking stupid.

Statins Have No Primary CVD Prevention Benefit To Older Patients

Takeaway
Statins offer no benefit for the primary prevention of cardiovascular disease (CVD) in adult patients aged ≥65 y.

Why this matters
“[S]tatins may be producing untoward effects in the function or health of older adults that could offset any possible cardiovascular benefit,” say the study authors.

Study design
Researchers conducted post hoc secondary data analyses of patient data from a randomized, open-label clinical trial (N=2867; age, ≥65 y; 49.4% women; all without evidence of atherosclerotic cardiovascular disease); patients were assigned to either a treatment group receiving pravastatin sodium 40 mg/d or a usual care (UC) group.
Funding: National Heart, Lung, and Blood Institute; AstraZeneca; Bristol-Myers Squibb; Pfizer; National Center for Advancing Translational Sciences; The Stroke Foundation.

Key results
Hazard ratios for all-cause mortality in the treatment group vs the UC group were

Rethinking Addiction

Perhaps you’ve studied the 12-Step program, or perhaps you’ve practiced it. I have done both. Practicing it was not as a matter of addiction, or any such thing for myself, but instead, was a part of my personal spiritual growth and development.

Over the years, I’ve heard commentary, or news features which interviewed people with divergent perspectives on 12-Step programs, most notably which were skeptical of them, and were thoughtfully seeking answers themselves for the “whys and wherefores” of substance abuse, whether it’s long-term or temporary, and whether it is a genetic fault, or if it is a personality or character flaw in response to external or internal stressors. In other words, it’s the classic “Heredity vs Environment” argument.

As I have come to view it, there is validity for both sides, but I think the stronger case is made for a combination of environment and character flaw, instead of genetic defect.

“In his recent book, The Sober Truth: Debunking the Bad Science Behind 12-Step Programs and the Rehab Industry, Lance Dodes, a retired psychiatry professor from Harvard Medical School, looked at Alcoholics Anonymous’s retention rates along with studies on sobriety and rates of active involvement (attending meetings regularly and working the program) among AA members. Based on these data, he put AA’s actual success rate somewhere between 5 and 8 percent. That is just a rough estimate, but it’s the most precise one I’ve been able to find.”

In Response to John Goodwin’s FaceBook Post

A man named John Goodwin made a public post on FaceBook, which also included a link to an OpEd published in the Washington Post on November 9, 2016, which was written by Charles Camosy (PhD, University of Notre Dame), and entitled “Trump won because college-educated Americans are out of touch.” Dr. Camosy is an Associate Professor of Theological and Social Ethics at Fordham University, and the author of a book entitled “Beyond the Abortion Wars: A Way Forward for A New Generation.”

Mr. Goodwin’s FaceBook profile is sufficiently ambiguous of himself, though in his public post which is time & date-stamped 9:45AM, November 10, 2016, and ostensibly geolocated from Washington, D.C., he wrote of himself that, “I haven’t posted about the election mostly because 1) I do this for a living and most of you don’t,” which would lead one to suppose that at some level, he works in or with public policy, or more likely, with politicians.

I do not.

However, suffice it to say, that for many, many, many years, I have remained immensely interested in public policy, though I do not now, nor have I ever made my living from it, or influencing, or attempting to influence others in elected office.

In other words, I have taken the high road.

Mr. Goodwin’s public post to FaceBook is linked herein, as is the article upon which he expounded.

In order to fully understand the matter of discussion herein, I encourage the reader to fully read this item following herein, as well as Mr. Goodwin’s post, and the OpEd upon which he opined

I have responded to Mr. Goodwin’s post as follows:
His words appear italicized, and in “quotation marks.”
My commentary follows immediately after.

“…not everyone lives in big cities.”
• That is correct. The United States Census Bureau says that 80.7% of American reside in urban areas. In fact, they report that “the population density in cities is more than 46 times higher than the territory outside of cities.” So that leaves a whopping 19.3% in rural areas.

“I didn’t grow up with money.”
• Money had been invented by the time I was born. But seriously, someone votes for Donald Trump as if the wealthy are advocates for the impoverished or even the average American? C’mon. Mr. Born-With-A-Silver-Spoon-In-His-Mouth? Really?

“…not everyone went to elite colleges.”
• According to the United States Census Bureau, “in 2015, almost 9 out of 10 adults (88 percent) had at least a high school diploma or GED, while nearly 1 in 3 adults (33 percent) held a bachelor’s or higher degree.” I’m in the 33%. So I’m an elite. Thanks!

How TRUE is “largely poor, uneducated, and easy to command”? You’d be surprised… or, maybe not.

Remember how ANGRY some folks got when Michael Weisskopf (b.1946) of the Washington Post wrote on February 1, 1993 (link to original article with the WaPo’s editorial addendum) that the simple-minded evangelical groupies of Jerry Falwell (who himself died in 2007), Pat Robertson (b.1930), et al, that:
“The gospel lobby evolved with the explosion of satellite and cable television, hitting its national political peak in the presidential election of Ronald Reagan in 1980.

“Unlike other powerful interests, it does not lavish campaign funds on candidates for Congress nor does it entertain them. The strength of fundamentalist leaders lies in their flocks. Corporations pay public relations firms millions of dollars to contrive the kind of grass-roots response that Falwell or Pat Robertson can galvanize in a televised sermon. Their followers are largely poor, uneducated and easy to command.

“”The thing that makes them powerful is they’re mobilizable,” said Seymour Martin Lipset (d.2006), professor of public policy at George Mason University. “You can activate them to vote, and that’s particularly important in congressional primaries where the turnout is usually low.”

“Some studies put the number of evangelical Americans as high as 40 million, with the vast majority considered politically conservative.”

[ed. note: The excerpt, which has frequently been distilled to “largely poor, uneducated and easy to command,” is provided here in full proper context with leading and following sentences, not merely excerpted, in order to thoroughly show proper context.]

It’s true.

Folks don’t get mad because of falsehoods.

They get mad because of truth.

It’s true.

According to the United States Census Bureau (USCB), in 2015 (22 years AFTER that was written), 32.5% of the American public aged 25, or older, have a Bachelor’s Degree (Table 1.), which is CLEARLY a minority. Thus, we see automatically the “largely” part of “uneducated.”

The USCB has also performed research on income, which is similarly delineated and categorized by education. For the year 2011 (18 years AFTER the remarks were made), and those aged 25+ with at least a Bachelor’s Degree, the average income was

Criticizing Stephen Hawking

Renown astrophysicist Stephen Hawking appeared on the Larry King Now show June 2016, and was interviewed by the esteemed long-time journalist.

In the interview, among the comments Hawking made was that “We certainly have not become less greedy or less stupid. The population has grown by half a billion since our last meeting, with no end in sight. At this rate, it will be eleven billion by 2100.”

News of the interview was covered by USA Today, and subsequently by The Intellectualist website, both which focused upon Professor Hawking‘s remark as referenced above.

This is worth noting:
The article quoted Hawking as saying,

September 7, 2015
Raising the minimum wage could benefit health, say researchers. 

 A 10% increase in wages leads to a 5% decrease in the rate of smoking. That is especially true for male employees with a low level of education, report scientists from the UC Davis Health System in Sacramento in the “Annals of Epidemiology.” Moreover, the likelihood of quitting smoking increases from 17-20%.

For their study, researchers analyzed data from full time workers aged 21 to 69 in the years 1999 to 2009 and

Meteorology, Mama & Baby -or- How I Was Befriended By Luck

It was Easter Sunday, 2010, and unknown to me, dumb luck had befriended me.

Pure dumb luck.

Even scientists believe in it.

In 1996, Duncan C. Blanchard, a meteorological researcher then affiliated with the State University of New York at Albany, authored a scientific paper entitled “Serendipity, Scientific Discovery, and Project Cirrus” published in the Bulletin of the American Meteorological Society in which he cited Project Cirrus (1947-52), a period and project of research from which “many serendipitous discoveries and inventions were made, opening up areas of research still being pursued today.”

Blanchard’s work was cited a decade later in 2006 by David M. Schultz, who was then affiliated with the Cooperative Institute for Mesoscale Meteorological Studies, University of Oklahoma, Norman, Oklahoma, and the NOAA/National Severe Storms Laboratory, Norman, Oklahoma in a research paper entitled The Mysteries of Mammatus Clouds: Observations and Formation Mechanisms. In it he wrote that what little we know about mammatus clouds was, because of their nature, “obtained largely through serendipitous opportunities.”

In other words, what little we know about the clouds (so named after human breasts because of their appearance), has been obtained by pure dumb luck – although, being prepared, and being in the right place at the right time does account for something.

In conversation recently with a dear, and longtime friend, I shared about

Study: Cannabis Legalization Does Not Increase Underage Use

Consumption Of Marijuana With Respect To The Passage Of Respective State Medical Marijuana Laws

The Lancet Psychiatry – Jul 20, 2015

    The Passage Of Medical Marijuana Laws Could Improvise Medical Usage Of Marijuana, With Due Investigation

 

Background

 Adolescent use of marijuana is associated with adverse later effects, so the identification of factors underlying adolescent use is of substantial public health importance. The relationship between US state laws that permit marijuana for medical purposes and adolescent marijuana use has been controversial. Such laws could convey a message about marijuana acceptability that increases its use soon after passage, even if implementation is delayed or the law narrowly restricts its use. We used 24 years of national data from the USA to examine the relationship between state medical marijuana laws and adolescent use of marijuana.

Evolution is not Contradictory to Scriptural Creation

And God said, “Let there be light,” and POOF! As if by magic, the sun suddenly appeared fully formed and functional!

And God said, “Let the water teem with living creatures, and let birds fly above the earth across the vault of the sky.” And POOF! As if by magic, every bird and fish was fully formed & functional, and there were bazillions of ’em!

Then God said, “Let us make mankind in our image.” And POOF! As if by magic, Adam, the first human, was fully formed and functional.

Sounds ludicrous, doesn’t it?

It should. Yet that’s precisely what it says. Of course, the “And POOF! As if by magic” part was added for purposes of ludicrous illustration.

And, it is equally preposterous to imagine that God is a magician, and that POOF! As if by magic, everything just suddenly appeared.

What we see and understand – if we can use observations of the natural world to guide us – is that
