Birmingham, Alabama Mayor Randall Woodfin Pardons 15,000 Cannabis Offenders On 420

Birmingham, Alabama Mayor Randall Woodfin has used the executive authority of the mayor’s office to issue blanket pardons for all misdemeanor marijuana-related offenses issued by the city from 1990-2020.

His actions were on April 20th, a day adopted by cannabis advocates as their celebratory day, and he Tweeted that,

“Today, I issued a pardon of 15,000 people convicted of marijuana possession in Birmingham between 1990-2020. These pardons are

Feel Like Overturning A Few Elections? Here’s Where It’s Now Happening.

Imagine for a minute, if you can, what it would be like for your elected Representatives and Senators, at either the State, or Federal level to literally “undo,” or attempt to “undo,” an election that was in every way conducted properly (meaning ethically, honestly, and openly, in accordance with all applicable laws), simply because they didn’t “like” the way The People voted – the results or outcome of the election wasn’t to their suiting, or liking.

There was such an attempt at the State level by the former President – the most notably infamous one being an hour-long phone call to the Georgia Secretary of State Brad Raffensperger, of which there is a publicly available audio recording of the entire call (transcript of entire call here), in which the former President said numerous times “I just want to find 11,780 votes” (Joe Biden won Georgia by a margin of 11,779 votes) – trying to enlist Secretary Raffensberger’s assistance in his effort to “find” votes which would dishonestly, unjustly, inequitably, and illegally “throw” the election to himself.

The Fulton County, Georgia District Attorney and the Georgia State Attorney General’s Office are both investigating that matter in order to determine what, if any, election-related laws were broken in the course of that phone call, which may include “the solicitation of election fraud, the making of false statements to state and local governmental bodies, conspiracy, racketeering, violation of oath of office and any involvement in violence or threats related to the election’s administration.”

The audio taped recording of the Trump-Raffensperger phone call is quite likely much worse than any of the numerous covert so-called “smoking gun” audio tapes of Richard Nixon’s presidency. Nixon’s numerous recorded conversations with staff, and others, including of his phone calls, which detailed his involvement in the numerous crimes of the Watergate burglary/break-in, also revealed him to be paranoid.

And cockamamie conspiracy theories aside – especially and particularly the one of “The BIG Lie,” as told by the former President – NO ONE made any overt, or clandestine effort or attempt to “steal” any election from anyone. PERIOD.

But the point of the matter is this:
There are
GENUINELY
now-ongoing efforts
to literally “undo”
the results of honest elections
in the United States.

No, this is NOT a joke… and, NO this is NOT a conspiracy theory.

It is a documented fact.

What does it say for democracy and the democratic process if the expressed will of the people is somehow, overridden, undone, or cancelled?

Yeah… it’s that “cancel culture” thing.

And it is Republicans who are doing it.

Remember the thing about “psychological projection” – a morbid behavior in which people deny or defend in themselves the very characteristic or behavior they abjure and detest in others? It’s a type of “blame shifting,” and a refusal to accept either reality or responsibility.

Marijuana Foes Deploy New ‘Playbook’ To Thwart State Legalization, Upend Election Results

By Jeff Smith

Efforts to thwart voter-approved marijuana legalization in Mississippi, Montana and South Dakota are evidence of a “playbook” that reflects new legal strategies and greater willingness among local government officials to nullify election results, experts say.

Those efforts – led by anti-marijuana politicians and other opponents – threaten to stop or delay the implementation of new medical and recreational cannabis markets that would generate hundreds of millions of dollars in sales a year.

In Idaho, some state lawmakers are

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.

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

Arizona Voters Approve Adult Recreational Use of Cannabis

In November, Arizonans voted overwhelmingly to legalize recreational sales of cannabis to adults.

By a margin of 653,982 votes, or 50.2113%, Arizona voters in that state’s General Election approved Arizona Proposition 207, known as the “Smart and Safe Arizona Act.”

The state’s fiscal analysis stated that “Annual state and local sales tax collections on these purchases may reach $88 million in the next several years. The initiative also requires a one-time transfer from the Medical Marijuana Fund of $45 million for the Department of Health Services, a university tuition program, and an impaired driving program.”

Among other provisions, as stated in its purpose, the “Act permits limited possession, transfer, cultivation, and use of marijuana (as defined) by adults 21 years old or older; protects employer and property owner rights; bans smoking in public places; imposes a 16% excise tax on marijuana to fund public safety, community colleges, infrastructure, and public health and community programs; authorizes state and local regulations for the sale and production of marijuana by a limited number of licensees; requires impairment to the slightest degree for marijuana DUls; transfers monies from the Medical Marijuana Fund; permits expungement of some marijuana violations; and prescribes penalties for violations.”

Distribution of taxes collected upon its sale would be as follows:
• 33.0% to community colleges
• 31.4% to local law enforcement and fire departments
• 25.4% to the state and local transportation programs
• 10.0% to public health and criminal justice programs
• 0.2% to the Attorney General for enforcement

The state estimates that “based on a projected tax base of $1 billion, total state and local tax collections would be $254 million, including $166 million to the Smart and Safe Arizona Fund.”

“In its Medium-Series Population Projections, the Arizona Office of Economic Opportunity (OEO) estimates that Arizona’s population will have reached 7.59 million by 2023. Given the $137 estimate for per capita sales, the OEO population estimate implies Arizona would have $1.04 billion of recreational marijuana sales in 2023.”

$254,391,600

Their revenue and sales estimates are based upon western states experiences, and they wrote that, “Arizona marijuana sales may increase further after the third year. States with more than 3 years of sales data have experienced continued growth in years 4 and 5. In Colorado, Oregon, and Washington recreational marijuana sales grew by a weighted average of 20.5% in year 4. In Colorado, the only state with 5 full years of data, sales grew by another 11.2% in year 5. We do not attempt, however, to project past the third year due to the speculative nature of long-run forecasting.”

The Arizona analysis also examines the cost associated with expungement, meaning the legal elimination of any criminal record associated with whatever record is being expunged. They cited a Pew Charitable Trusts analysis in November 2017, which stated in part that, “California only had 1,506 applications for expungement its first year of legalization and Oregon saw only 1,206 petitions combined between 2015-2017. Furthermore, the 192,000 estimate includes all convictions for marijuana possession, whereas the initiative provides the expungement option only to those who were convicted of marijuana possession of 2.5 ounces or less.”

They also note as well, that “the initiative does provide a revenue source for DPS administrative costs. The initiative authorizes DPS to collect a “reasonable fee determined by the Director” for costs to “correct the petitioner’s criminal history record” unless the individual is indigent.”

Control, or rather, elimination of the illicit black market is also a strong motivator for government in the legalization, taxation, and regulation of cannabis, especially and particularly for Adult Recreational Use. To that end, Arizona’s fiscal analysts wrote that, “If the limited number of retail locations authorized under the initiative is insufficient to meet demand, then current marijuana users may be more likely to continue to purchase illegally or from medical dispensaries, potentially decreasing the size of the legal market.”

Elimination of the illicit black market was also a very strong motivating factor in Oklahoma’s recent liberalization of cannabis laws, particularly and especially for medical use. See “Oklahoma Has Become A Free Market Utopia For Weed,” published 11/2/2020 for more details. Of course as well, an “unintended consequence” for ALL states which have liberalized their cannabis laws, is an INCREASE in private enterprise, and entrepreneurship – the veritable “holy grail” of most Republicans… and Democrats, if folks would be honest about the matter.

Arizona’s fiscal analysts also acknowledge a very important, yet almost-overlooked matter: It is of local regulation. They write that, “the proposition grants

House Banana Republicans Cower From Weed, Senate Slave Driver “Moscow” Mitch McConnell Goes Up In Smoke

Despite numerous polls from various polling organizations showing an increasing desire of a majority of Americans to legalize cannabis, House Banana Republicans have run away from The People’s will and desire to continue to exact increasingly costly tolls upon taxpayers burdened by incarcerating its consumers.

Pew Research Centers latest findings on Americans’ attitudes toward cannabis show that “an overwhelming majority of U.S. adults (91%) say marijuana should be legal either for medical and recreational use (59%) or that it should be legal just for medical use (32%),” and that “fewer than one-in-ten (8%) prefer to keep marijuana illegal in all circumstances.”

Gallup Polling most recently found similar figures.

“The 68% of U.S. adults who currently back the measure is not statistically different from last year’s 66%; however, it is nominally Gallup’s highest reading, exceeding the 64% to 66% range seen from 2017 to 2019,” they wrote on November 9, 2020.

Fifteen states and the District of Columbia have legalized the plant for recreational purposes, while 36 states – plus the District of Columbia, Guam, Puerto Rico, and the U.S. Virgin Islands – have legalized the drug for medical purposes.

Cannabis, also commonly known as “marijuana,” remains illegal under U.S. federal law.
H.R.3884 Marijuana Opportunity Reinvestment and Expungement Act of 2019 or the MORE Act of 2019 (“To decriminalize and deschedule cannabis, to provide for reinvestment in certain persons adversely impacted by the War on Drugs, to provide for expungement of certain cannabis offenses, and for other purposes.”) was introduced by Jerrold Nadler (D, NY-10), had 120 cosponsors, passed through 8 committees: House – Judiciary; Energy and Commerce; Agriculture; Education and Labor; Ways and Means; Small Business; Natural Resources; Oversight and Reform.

Roll Call Number 235 on Roll Call 235, Bill Number: H. R. 3884, was held Friday, December 04, 2020, 01:08 PM EST, in the 116th Congress, 2nd Session.

The bill also makes other changes, including the following:

• • replaces statutory references to marijuana and marihuana with cannabis,
  • requires the Bureau of Labor Statistics to regularly publish demographic data on cannabis business owners and employees,
  • establishes a trust fund to support various programs and services for individuals and businesses in communities impacted by the war on drugs,
  • imposes a 5% tax on cannabis products and requires revenues to be deposited into the trust fund,
  • makes Small Business Administration loans and services available to entities that are cannabis-related legitimate businesses or service providers,
  • prohibits the denial of federal public benefits to a person on the basis of certain cannabis-related conduct or convictions,
  • prohibits the denial of benefits and protections under immigration laws on the basis of a cannabis-related event (e.g., conduct or a conviction),
  • establishes a process to expunge convictions and conduct sentencing review hearings related to federal cannabis offenses, and
  • directs the Government Accountability Office to study the societal impact of cannabis legalization.

House Votes To Decriminalize Marijuana As GOP Resists National Shift On Pot

by Mike DeBonis
December 4, 2020 at 2:34 p.m. EST

The measure is not expected to pass into law, and, due to political skittishness, it was only voted on after the November election and more than a year after it emerged from committee. But the House took a stand at a moment of increasing momentum, with voters last month opting to liberalize marijuana laws in five states — including three that President Trump won handily.

Friday’s vote, however, was largely along party lines, with

Oklahoma Has Become A Free Market Utopia For Weed

Nothing short of amazing!

Other states should take notice.

Oklahoma State Representative Scott Fetgatter (R-16)

Witness the Free Market and Free Enterprise at work collaborating with government with practically nominal regulation.

The primary difference being, is that the heavy hammer of law hangs over the heads of individuals whom violate the law, and licensing/permitting is required throughout the process – from producer to consumer – and, it is taxed.

“Anybody who wants to use marijuana is already using marijuana.
You’re not stopping that.
The goal is to eliminate the black market.”
– Oklahoma State Representative Scott Fetgatter (R-16)

“They’ve literally done what no other state has done: free-enterprise system, open market, wild wild west. It’s survival of the fittest.”

How One of the Reddest States Became the Nation’s Hottest Weed Market

Oklahoma entered the world of legal cannabis late, but its hands-off approach launched a boom and a new nickname: ‘Toke-lahoma.’

WELLSTON, Oklahoma—One day in the early fall of 2018, while scrutinizing the finances of his thriving Colorado garden supply business, Chip Baker noticed a curious development: transportation costs had spiked fivefold. The surge, he quickly determined, was due to huge shipments of cultivation supplies—potting soil, grow lights, dehumidifiers, fertilizer, water filters—to Oklahoma.

Baker, who has been growing weed since he was 13 in Georgia, has cultivated crops in some of the world’s most notorious marijuana hotspots, from the forests of Northern California’s Emerald Triangle to the lake region of Switzerland to the mountains of Colorado. Oklahoma was not exactly on his radar. So one weekend in October, Baker and his wife Jessica decided to take a drive to see where all their products were ending up.

Voters in the staunchly conservative state had just four months earlier authorized a medical marijuana program and sales were just beginning. The Bakers immediately saw the potential for the fledgling market. With no limits on marijuana business licenses, scant restrictions on who can obtain a medical card, and cheap land, energy and building materials, they believed Oklahoma could become a free-market weed utopia and they wanted in.

Chip Baker smokes a joint in his house at the farm where he grows marijuana in Wellston, Oklahoma.

Within two weeks, they found a house to rent in Broken Bow and by February had secured a lease on an empty Oklahoma City strip mall. Eventually they purchased a 110-acre plot of land down a red dirt road about 40 miles northeast of Oklahoma City that had previously been a breeding ground for fighting cocks and started growing high-grade strains of cannabis with names like Purple Punch, Cookies and Cream and Miracle Alien.

“This is exactly like Humboldt County was in the late 90s,” Baker says, as a trio of workers chop down marijuana plants that survived a recent ice storm. “The effect this is going to have on the cannabis nation is going to be incredible.”

Oklahoma is now the biggest medical marijuana market in the country on a per capita basis. More than 360,000 Oklahomans—nearly 10 percent of the state’s population—have acquired medical marijuana cards over the last two years. By comparison, New Mexico has the country’s second most popular program, with about 5 percent of state residents obtaining medical cards. Last month, sales since 2018 surpassed $1 billion.

To meet that demand, Oklahoma has more than 9,000 licensed marijuana businesses, including nearly 2,000 dispensaries and almost 6,000 grow operations. In comparison, Colorado—the country’s oldest recreational marijuana market, with a population almost 50 percent larger than Oklahoma—has barely half as many licensed dispensaries and less than 20 percent as many grow operations. In Ardmore, a town of 25,000 in the oil patch near the Texas border, there are 36 licensed dispensaries—roughly one for every 700 residents. In neighboring Wilson (pop. 1,695), state officials have issued 32 cultivation licenses, meaning about one out of 50 residents can legally grow weed.

“Turns out rednecks love to smoke weed. That’s the thing about cannabis: It really bridges socio-economic gaps.”

– Chip Baker

What is happening in Oklahoma is almost unprecedented among the 35 states that have legalized marijuana in some form since California voters backed medical marijuana in 1996. Not only has the growth of its market outstripped other more established state programs but it is happening in a state that has long stood out for its opposition to drug use. Oklahoma imprisons more people on a per-capita basis than just about any other state in the country, many of them non-violent drug offenders sentenced to lengthy terms behind bars. But that state-sanctioned punitive streak has been overwhelmed by two other strands of American culture—a live-and-let-live attitude about drug use and an equally powerful preference for laissez-faire capitalism.

“Turns out rednecks love to smoke weed,” Baker laughs. “That’s the thing about cannabis: It really bridges socio-economic gaps. The only other thing that does it is handguns. All types of people are into firearms. All types of people are into cannabis.”

Indeed, Oklahoma has established arguably the only free-market marijuana industry in the country. Unlike almost every other state, there are no limits on how many business licenses can be issued and cities can’t ban marijuana businesses from operating within their borders. In addition, the cost of entry is far lower than in most states: a license costs just $2,500. In other words, anyone with a credit card and a dream can take a crack at becoming a marijuana millionaire.

“They’ve literally done what no other state has done: free-enterprise system, open market, wild wild west,” says Tom Spanier, who opened Tegridy Market (a dispensary that takes its name from South Park) with his wife in Oklahoma City last year. “It’s survival of the fittest.”

The hands-off model extends to patients, as well. There’s no set of qualifying conditions in order to obtain a medical card. If a patient can persuade a doctor that he needs to smoke weed in order to soothe a stubbed toe, that’s just as legitimate as a dying cancer patient seeking to mitigate pain. The cards are so easy to obtain—$60 and a five-minute consultation—that many consider Oklahoma to have a de facto recreational use program.

But lax as it might seem, Oklahoma’s program has generated a hefty amount of tax revenue while avoiding some of the pitfalls of more intensely regulated programs. Through the first 10 months of this year, the industry generated more than $105 million in state and local taxes. That’s more than the $73 million expected to be produced by the state lottery this fiscal year, though still a pittance in comparison to the overall state budget of nearly $8 billion. In addition, Oklahoma has largely escaped the biggest problems that have plagued many other state markets: Illegal sales are relatively rare and the low cost to entry has made corruption all but unnecessary.

Bottom left: Chris Hayes snips a tie connecting bamboo supports to a plant before harvesting it. Bottom right: The farm uses soil bags Baker designed to efficiently grow and harvest plants.

All of which has made Oklahoma an unlikely case study for the rest of the country, which continues its incremental march toward universal legalization. Oklahoma is

Mississippi Voters To Decide On Medical Marijuana

If you have family and friends whom reside in Mississippi, the following will be of particular interest to you.

If not, it will still be of significant interest. We’ll explain why momentarily.

First, some background.

This year, Mississippians will have the opportunity to vote on whether, or not, they want to avail themselves, their loved ones, and friends, of the opportunity to use cannabis to treat the symptoms of their diseases.

The bill which would bring Medical Marijuana to Mississippi is called Initiative 65. The bill is fully written, and is not a mere hollow proposal. Establishing a complete infrastructure, Initiative 65 thoroughly lays out the plans by and through which cannabis would become available to medically qualifying Mississippians, including the regulatory agency and mechanism, the taxation structure, prescriptive authority, distributive network, farming and production facilities, product safety testing mandates, and more.

Mississippi, like some other states, has a public initiative process by and through which citizens have the ability to facilitate legislative action outside of their legislature. It is a direct type of democratic involvement, which for them is ensconced in their State Constitution. The Mississippi Secretary of State’s website writes explicitly that, “The Mississippi initiative law affords voters an avenue for addressing important constitutional issues which the State Legislature does not.”

The site further references the qualifying conditions that must be met in order for any prospective measure to be placed on the ballot – and win – by stating that,

“for an initiative measure to be placed on the ballot, a minimum of 106,190 certified signatures must be gathered with at least 21,238 certified signatures from each of the five congressional districts as they existed in the year 2000. Signatures must be certified by county circuit clerks. A completed petition is filed with the Secretary of State’s Office, along with a $500 filing fee. Not only must an initiative receive a majority of the total votes cast for that particular initiative, it must also receive more than 40% of the total votes cast in that election.”

Suffice it to say, the state law establishes a very high standard which prospective initiative measures must meet in order for them to be placed on the ballot, and then to pass. Whereas in most other states, a simple majority is often all that’s required for any candidate or measure to win, or to pass, in Mississippi, that state’s Initiative Law requires that IN ADDITION TO meeting all other qualifying conditions, it must be voted upon by AT LEAST 40.1% of all voters/ballots cast.

For purposes of illustration – if there are 100 TOTAL voters/ballots cast in an election, and only 30 out of the 100 voters voted on the measure (called an “undervote,” a condition in which all voters do not bother to vote on a particular race or measure), and voted for it to pass, and the nay votes were -0- (zero), despite the 30-0 victory margin, it will NOT pass, because it did NOT “receive more than 40% of the total votes cast in that election.”

Again, despite the fact that more voters voted FOR the measure to pass, than voted against it (which in this example would be zero -0-), or did NOT vote upon it, the measure still would not be considered to have passed.

Enter Mississippians for Compassionate Care.

Comprised of 76 diverse individuals from a variety of backgrounds including Physicians, Nurse Practitioners and Professors, Registered Nurses, Republican and Democratic politicians, Party Executive Committee members, State Legislators, and Local Officials from both major parties, Ministers, retired Military Service members, Business Owners and Executives, District Attorneys, retired Law Enforcement Officers, and more, they are the members of the steering committee which are guiding the measure called Initiative 65 which, if approved by voters, would establish a Medical Marijuana Law in Mississippi.

Initiative 65 is a well-though-out bill, one which is thoroughly considered, and the bill for the prospective measure contains practically every aspect of consideration which would be involved in establishing an entire infrastructure for Medical Marijuana.

The bill MS Initiative 65 Proposed Measure may be read/downloaded here.

Enter the Mississippi State Legislature.

Over the years, in over 20 attempts, the state’s legislators quashed every effort to help the people, and not once did they ever

QUESTION: CB1 receptors are expressed by neurons in the brain, especially in the cerebral cortex, basal ganglia, cerebellum, and hippocampus. Are CB1 receptors expressed in other parts of the nervous system? Are CB1 receptors present on cells outside of the nervous system?

ANSWER: In addition to being expressed by neurons in the brain, CB1 receptors are also expressed in parts of the peripheral and autonomic nervous system. CB1 receptors are also expressed on several other tissues, including heart, lung, reproductive organs, thymus and spleen.

–––

QUESTION: Does the consumption of THC and CBD via vaporization impair driving ability?

ANSWER: A recent study published in JAMA examined the magnitude and duration of driving impairment following vaporization of cannabis containing various concentrations of THC and CBD. The results of the study indicated that the impairment of driving after consuming vaporized THC-dominant and 50:50 THC/CBD cannabis compared with placebo was significantly greater at 40-100 minutes but not at 240-300 minutes after vaporization. There were no significant differences between CBD-dominant cannabis and placebo found, but the doses tested may not represent common usage.

–––

QUESTION: To which receptor do cannabinoids bind that impact pain sensation?

ANSWER: In addition to acting on cannabinoid receptors (CB1 and CB2), cannabinoids may modulate pain by interacting with the G protein-coupled receptor 55 (GPR55) and GPR18 and other G protein-coupled receptors such as serotonin and opioids receptors. Cannabinoids also interact with TRPV-1 receptors. CBD and THC (along with the endocannabinoid, Anadamide) activate glycine receptors, and as a result, lead to analgesia in inflammatory and neuropathic pain.

–––

QUESTION: Does the anti-fungal agent ketoconazole interact with cannabinoids?

ANSWER: Yes. Ketoconazole Inhibits the metabolism of THC and CBD and can significantly increase concentrations of THC and CBD. In contrast, drugs such as rifampicin, carbamazepine and St John’s Wort induce cytochrome enzyme activity and lower THC and CBD concentrations.

–––

QUESTION: If a patient is allergic to tomatoes or tobacco, is the patient a good candidate for medical marijuana therapy?

ANSWER: Patients who have previously experienced an allergic reaction to tobacco or tomato are at increased risk for developing an allergy to the products from the cannabis plant.

–––

QUESTION: Is a “full spectrum” product the same as a “whole plant” product?

ANSWER: No. “Whole plant” products contain fats, waxes and fibrous materials not found in “full spectrum” products.

–––

QUESTION: What does “full spectrum” marijuana mean? What does “broad spectrum” mean?

ANSWER: Full spectrum means that the product contains all of the original compounds found in the flower of the cannabis plant (cannabinoids, terpenes and flavonoids). In contrast, broad spectrum products are processed in such a manner as to ensure that the final product does NOT contain THC.

–––

QUESTION: Describe the exact mechanism of action of Epidiolex.

ANSWER: According to the Epidiolex FDA Approved Package Insert, (Greenwich Biosciences, Inc.), the precise mechanism(s) by which Epidiolex exerts its anticonvulsant effects in humans are unknown. It does not appear to be through cannabidiol receptors.

–––

QUESTION: Have the results of studies examining the impact of maternal marijuana use identified a unique phenotypic congenital anomaly?

ANSWER: Studies evaluating maternal use of marijuana have not found a unique phenotypic signature of prenatal exposure of marijuana. There does appear to be an increased risk of congenital anomalies, particularly gastroschisis, though.

–––

QUESTION: In 2018, Epidiolex was approved for the treatment of seizures associated with two rare and severe forms of epilepsy, Lennox-Gastaut syndrome (LGS) and Dravet syndrome (DS). Has the FDA approved Epidiolex for any other conditions since 2018?

ANSWER: Yes. On July 31, 2020, the U.S. Food and Drug Administration approved Epidiolex (cannabidiol or CBD) oral solution for the treatment of seizures associated with tuberous sclerosis complex (TSC) in patients one year of age and older.

–––

QUESTION: Does the use of cannabinoid-based products impact female sexual function, including desire, arousal, lubrication, orgasm, satisfaction, and pain?

ANSWER: According to a study published in the journal Sexual Medicine, an increased frequency of marijuana use is associated with improved sexual function among females. (i.e. – sexual desire increased, arousal increased, orgasm domain increased, and sexual satisfaction increased.) Interestingly, it was noted that chemovar type and method of consumption did not impact outcomes, though.

–––

QUESTION: Does consuming a high fat/high calorie meal at the same time as you take liquid CBD orally impact the amount of CBD absorbed into the bloodstream?

ANSWER: Yes. According to studies performed by a pharmaceutical company that manufactures an FDA- approved CBD product, a high fat/high calorie meal can increase CBD absorption by up to 5 fold.

–––

QUESTION: Did the United Nations Commission for Narcotic Drugs vote in December 2020 to accept the World Health Organization’s (WHO) recommendation to remove cannabis and cannabis resin for medicinal purposes from Schedule IV of the 1961 Single Convention on Narcotic Drugs?

ANSWER: Yes, and it was a close one (27 to 25), with the United States and many European nations in favor. The US published a statement about its rationale for the vote – “The vote of the United States to remove cannabis and cannabis resin from Schedule IV of the Single Convention while retaining them in Schedule I is consistent with the science demonstrating that while a safe and effective cannabis-derived therapeutic has been developed, cannabis itself continues to pose significant risks to public health and should continue to be controlled under the international drug control conventions. Further, this action has the potential to stimulate global research into the therapeutic potential and public health effects of cannabis, and to attract additional investigators to the field, including those who may have been deterred by the Schedule IV status of cannabis.”

QUESTION: The House of Representatives approved the MORE Act. Is marijuana legal now?

ANSWER: The House of Representatives approved the bill called the MORE Act on December 4, 2020, but marijuana is not legal at the federal level. The bill must go to the Senate, and then the White House for the President to sign. Until the President signs it, it’s not a law – it’s just a bill.

QUESTION: The findings of multiple randomized controlled trials (RCTs) indicate that cannabinoids effectively treat chronic pain. Do cannabinoids effectively treat the chronic pain associated with fibromyalgia?

ANSWER: No. According to a Cochrane systematic review published in 2016 on the use of cannabinoids to treat fibromyalgia, there is no convincing, unbiased, high-quality evidence suggesting that a cannabinoid-based medicine (nabilone) is of value in treating people with fibromyalgia. Furthermore, the tolerability of nabilone was low in people with fibromyalgia. Also, the results of a 2019 study where 4 varieties of pharmaceutical grade marijuana were administered by single shot vapor to fibromyalgia patients indicated that none of the 4 marijuana varieties had an effect greater than placebo. (Note: The data from the 2019 study could not be used to extrapolate the long-term effects of cannabinoids on fibromyalgia-associated 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: 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: 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: 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: 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: 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: The 2017 National Academies of Sciences, Engineering and Medicine’s (NASEM)review on the health effects of cannabinoid-based medicines concluded that there was conclusive or substantial evidence for the use cannabis or cannabinoids for the treatment of pain in adults. Do other national regulatory bodies have similar conclusions to the NASEM’s conclusion?

ANSWER: Actually, no. The Health Products Regulatory Authority of Ireland does not support the use of cannabinoid-based medicines for the treatment of chronic pain. Also, the European Pain Federation’s recent position paper recommended cannabinoid-based medicines be considered for chronic neuropathic pain only as a third line agent. Furthermore, the European Pain Federation found that the results of the studies examining chronic non-cancer pain indicated that there was insufficient evidence for the use of cannabinoid-based medicines for the treatment of non-neuropathic chronic non-cancer pain.

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.

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
