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

Is North Korea Behind U.S. Fentanyl Deaths?

Fentanyl-laced marijuana has been found in Connecticut.

This is yet ANOTHER damn good reason to:
1.) Legalize;
2.) Tax, and;
3.) Regulate
cannabis — 100%, for Adult Recreational, and Medical Use.

It should be noted, that in Connecticut, Adult Recreational Use of cannabis (aka “marijuana”) is legal, and like in every other state where it is legal, in one form, or another (as Adult Recreational and/or Medical), is subject to rigorous testing and held to the highest standards… no pun intended.
See: https://portal.ct.gov/cannabis/

The fentanyl-laced marijuana was purchased on the black market, which much like illegally-produced liquor during Prohibition, also caused death, and blindness. Now, home-based beer and wine production, along with distilling and entrepreneurship in spirituous beverage production, is legal nation-wide, and such problems are exceedingly rare.

“This is the first lab-confirmed case of marijuana with fentanyl in Connecticut and possibly the first confirmed case in the United States.”

— Dr. Manisha Juthani, MD, Connecticut Department of Public Health Commissioner

The Connecticut Overdose Response Strategy (CT ORS) and the Connecticut Department of Public Health, Office of Emergency Medical Services, have recently received reports of overdose patients who have exhibited opioid overdose symptoms and required naloxone for revival. These patients denied any opioid use and claimed to have only smoked marijuana.

Recent incidents where only marijuana use was reported but naloxone was required.

• July 2021 – 11 cases
• August 2021 – 9 cases
• September 2021 – 9 cases
• October 1 – 26, 2021 – 10 cases

The reported incidents were dispersed across Connecticut. Several jurisdictions had multiple overdoses with opioid symptoms attributed to marijuana, however, no pattern was detected. In early October 2021, Plymouth, CT, had several overdose incidents where naloxone was required for revival and patients claimed to have only smoked marijuana. At one of these overdose scenes, Plymouth Police Department was able to secure a sample of the marijuana for testing at the state laboratory, which tested positive for fentanyl.

A legal marijuana crop in Uruguay.

But here’s the kicker:
How long before black market fentanyl-laced marijuana makes its way down South, or to other areas of the nation?

And here’s another thought:

EVERYBODY who’s been paying attention knows how lethal fentanyl is, and the numerous deaths that are arising from its deliberate contamination in other street drugs such as heroin, methamphetamine, cocaine, and now, cannabis. And, for a person/group in such a “business” would have to be a fool to distribute a substance that they knew would kill their clientele. It’s just bad for business to destroy your customer base. So, why would any one in their proper mind do that, eh?

I submit to you that NO narcotrafficking cartel would even stoop that low, or be that stupid, to eliminate their customers.

And so, if it’s not a narcotrafficking cartel, who could it be?

It’s just my opinion, of course, but consider the possibility that it actually –might– be America’s enemies, like North Korea, Russia, China, etc. It’d be a fantastic way to eliminate your enemy little-by-little, inch-by-inch, and in that process, demoralize their resolve, and divert resources.

I continue to maintain, for example, that

Conservative Oklahoma Shows States How To Run Medical Marijuana Program

Oklahoma State Representative Scott Fetgatter (R-16)

“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)

Legislators there (in OK) understand at least one thing: A truly “free market” is regulated at a minimum. Of course, some regulation is necessary, and as I’ve often said, regulation makes things operate more effectively and efficiently, much like a fine-tuned automobile engine, or any sports competition. But there is a point of diminishing returns at which increased effort will not increase output.

Another benefit of minimal regulation, is reduced criminal activity.

Many have made the argument that, in a manner similar to America’s Prohibition Era, in which organized crime was born, Nixon’s 50-year failed social experiment known as the “War on Drugs” has created global narcotrafficking cartels.

And indeed, it may, or may not, surprise you know that the Drug Enforcement Administration has offices and agents worldwide. And yet, for all that effort, and money spent, drug abuse has flourished, rather than diminished, and our nation’s prisons, and jails have proliferated populations, which are much more than a mere tax burden upon society, but rob the market economy of labor, and steal husbands and fathers from families. And then, once they’ve fully “paid their debt to society,” they’re further penalized – in essence, given a life sentence – through the legally enforced social stigma of possessing an arrest record, or having served time. Just think about it: When was the last time you saw, heard, or read, of a job advertisement that specifically stated “We hire ex-cons,” or “Former felons encouraged to apply”? Probably never. So much for so-called “corrections programs,” eh?

And then, there’s this prima facie fact as well, that no one in their right mind wakes up one day and says to themselves, “Gee… I think I want to become an addict.” No one.

We human beings are complex creatures, and it is impossible to point directly to one thing, and one thing only as the cause of addiction. Suffice it to say, that there are many factors, some of which include physical (including sexual) and/or emotional abuse, or other trials and tribulations of life. Some, as well, have been victimized by poor medical care, such as over-prescribing of narcotics by reckless, lackadaisical, or greedy physicians, some of whom have operated “pill mills,” indiscriminately dispensing huge volumes of narcotics for profit.

But, even the DEA (a Federal law enforcement agency), and reputable science and medical researchers have acknowledged that “No deaths from overdose of marijuana have been reported.” The same cannot be said of beverage alcohol. It’s literally impossible to die from over-consumption of cannabis, precisely because, unlike opioids, the psychoactive ingredient – THC – does not affect the brain stem (because there are no receptors there for it to attach to), which is where the body’s respiratory drive center is located. That is a finding of science made in 2020. Now, imagine this: Science would never have advanced by learning that seemingly minor fact if “Just say NO!” was effective (and it is not).

If you’d like to know more about cannabis science, I refer you to this science and fact-based page:

Why Red State Oklahoma Is Home To A Booming Medical Marijuana Market

Published June 28, 2021 
By John Schroyer

People outside the cannabis industry might be surprised to learn that the most liberal medical marijuana market in the country isn’t California anymore. Nor is it Colorado, Oregon or another left-leaning blue state.

It’s politically conservative Oklahoma.

The red state has pulled a U-turn on marijuana policy since 2014, when the state’s attorney general – along with his then-counterpart in Nebraska – filed a federal lawsuit to overturn neighboring Colorado’s new recreational marijuana program.
But the U.S. Supreme Court declined to hear the case.

Fast-forward to June 2018, when Oklahoma voters soundly approved one of the loosest medical marijuana programs in the country.

Two months later, Oklahoma regulators began accepting applications for MMJ business licenses.

Sales began that December, by which point the state already had nearly 900 dispensaries, and it’s been pushing the envelope since then when it comes to MMJ policy.

Today, business is booming.

Oklahoma has more than 2,000 dispensaries – the most in the nation. And the 2021 MJBizFactbook projects

America Invented Global Narcotraffickers

Make no mistake, I openly advocate for the wholesale legalization, taxation, and regulation of cannabis similarly as is done for beverage alcohol — though I have not always. And yet, as a licensed healthcare professional, I am under no misguided notion that there are genuine scientific considerations to be had.

Like many others, this is not a simple matter, per se — it is as complex as we human beings, with myriad matters which “Just Say ‘NO!’” has never, nor will ever, satisfy. Science and understanding is not advanced by the word “NO!”

Similarly as well, there is practically no disagreement that historic American jurisprudence on the matter not only had its genesis with deep roots in racism – which remains to this day – but has almost single-handedly created the global criminal cabal of narcotrafficking enterprises that have now become international terrorist organizations. It has now become a matter of national security, and not just for the United States. Global security is predicated upon addressing these concerns.

Jesus Malverde is a mythical figure, allegedly born as Jesús Juárez Mazo on December 24, 1870, just outside Culiacán, the state capital of Sinaloa, whom is said to be the “patron saint” of “narcotraficantes” (drug traffickers), and is known by his devotees as “el ángel de los pobres” (the angel of the poor).
According to legend, he was a lifetime resident of Sinaloa, an historically poverty-stricken area which is now recognized as the de facto headquarters location for a bloodthirsty global narcotrafficking cartel bearing the state’s name, which is infamous for their nefarious misdeeds, cold-blooded murders, and other heinous acts.
The legends, which vary widely, typically assert that Malverde was a “Robinhood” type character, who stole from the wealthy and distributed to the poor. In reality, narco-money has significantly revitalized Sinaloa, and to a large extent, reinforced ancient customs, including the veneration of folk saints as Jesus Malverde.

It is, in fact, fueling the civil sociopolitical upheaval in Central American nations such as

No Smoking, No Joking: Alabama’s Medical Marijuana Law Examined

Flowering bud (female) of the Cannabis Sativa plant, aka “marijuana”

There are 49 other states to which Alabama could turn to examine what works, and what does not, and could emulate the best of the best.

But, Alabama’s gonna’ Alabama, regardless of who, or what party’s in office.

---

Alabama patient advocates may have celebrated following “Guvnah Memaw’s” signature on the “Darren Wesley ‘Ato’ Hall Compassion Act” sponsored by Republican State Senator Dr. Tim Melson, MD (District 1).

But now, reality is about to set in.

The law, like so many others, is a fiasco. Citizens should rejoice the legislature cannot figure out how to connive and wheedle a gambling scheme to benefit themselves, or their “Big Mule” cronies.

Superficially, the “compassion act” sounds good.

That’s where it stops.

The law leaves patients high and dry when it comes to protecting them, and:

• Allows them to be fired without recourse, denied UC benefits, and denied Worker’s Comp benefits “regardless of the individual’s impairment or lack of impairment resulting from the use of medical cannabis.” {page 15, line 20, §20-2A-6(a)(10)} {page 16, line 13, §20-2A-6(a)(11)(c)}

But then, patient abandonment & neglect is Alabama’s forte.

• Allows DHR to remove children from a patient’s household, and states that the agency shall not be prohibited from “considering a parent or caretaker’s use of medical cannabis as a factor for determining the welfare of a child.” {page 16, line 19, §20-2A-6(a)(11)(d)}

• Penalizes diversion much more harshly than trafficking <500lbs of marijuana – 2 to 20 years vs 5 years + $50,000 fine, respectively. {Section 13A-12-231(1)(a)&(b)}

• Automatically suspends the driver’s license of “any person who is recommended a daily dosage of medical cannabis that exceeds 75 mg… regardless of whether he or she holds a valid medical cannabis card.” {page 99, line 9, Section 6}

• Taxes collected, over and above the board’s operating expenses, less 10%, will go to… The General Fund. {page 22, line 18, §20-2A-10(3)(c)}

No surprise there. It’s Alabama’s slush fund.

• Has an even number of voting board members (12), assuring deadlock on

Research: Most Religious Americans Support Broad Cannabis Legalization

A Pew Research Center survey conducted April 5-11, 2021 among 5109 randomly sampled U.S. adults who were all members of Pew Research Center’s American Trends Panel – a group of over 10,000 adults randomly selected from throughout all 50 states who regularly participate in Pew’s surveys – found that most religiously affiliated Americans favor broad cannabis legalization.

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,

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
Published February 18, 2021
https://mjbizdaily.com/marijuana-legalization-foes-aim-to-overturn-election-results/

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.

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

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.

  • 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

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.

You’re not stopping that.
The goal is to eliminate the black market.”

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.

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.

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: 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: 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.

ANSWER: No, the VHA recently recommended that clinicians discuss cannabis with their patients. However, according to a study published in February 2021, VHA clinicians identified several factors that inhibit conversations about cannabis use with their patients including the unfamiliarity with pharmacology, formulations, and dosing of cannabis; and uncertainty regarding VHA policy.

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.

QUESTION: The most well studied endocannabinoids are N-arachidonoyl- ethanolamine (AEA; anandamide) and 2-arachidonoylglycerol (2-AG). Are these two neurotransmitters stored in the presynaptic neurons?

ANSWER: No. Unlike most neurotransmitters, neither AEA or 2-AG is stored within vesicles in presynaptic neuron axons. 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: 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: In some legal states, edibles, such as candies, baked goods, beverages and condiments (butter and oils) containing THC may be sold. Is 2.5mg of THC in an edible a low dose or high dose of THC to be consumed orally?

ANSWER: The dosing of THC always needs to be adjusted on an individual basis. For reference, 2.5 mg is the lowest dose of dronabinol, a synthetic THC that is FDA-approved.

–––

QUESTION: When speaking with their clinicians, patients may use the terms “dabs”, “wax”, or “butane honey oil” – what do these terms mean?

ANSWER: Dabs, wax and butane honey oil are all highly concentrated cannabis extracts of THC. These THC products are often smoked or vaporized. Because these THC products are quite highly concentrated, the consumption of only a very small amount may produce a significant effect.

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 are conduction-based vaporizers?

ANSWER: Conduction-based vaporizers heat herbal cannabis on a surface that is warmed, such as a metal plate, which then allows compounds to passively volatilize. Meanwhile, the consumer generates a steady inhalation, similar to the technique used by asthma patients with metered-dose inhalers or nebulizers to achieve pulmonary administration.

–––

QUESTION: What physiological systems are affected by the endocannabinoid system?

ANSWER: In addition to regulating neuronal excitability and inflammation in pain circuits, the endocannabinoid system has been shown to play a regulatory role in movement, appetite, hypothalamic-pituitary-adrenal axis modulation, immunomodulation, mood, blood pressure, bone density, tumor surveillance, neuroprotection and reproduction. The endocannabinoid system has also been shown to affect sensory perception, cardiac output, cerebral blood flow and intraocular pressure.

QUESTION: What does cannabinergic mean?

ANSWER: Any drug that modifies or interacts with the endocannabinoid system is ‘cannabinergic’.

–––

QUESTION: What is the pharmacological profile of buccally administered cannabinoids?

ANSWER: With buccal administration, a mix of cannabinoids can be sprayed on to the oral mucosa and the medicine is absorbed through the mucous membranes. Peak plasma concentrations usually occur within 2-4 hrs after administration. When compared to inhalation of cannabinoids, buccal administration of cannabinoids is associated with lower blood levels of cannabinoids because absorption is slower, redistribution into fatty acids occurs rapidly and some of the cannabinoids undergo first pass metabolism.

QUESTION: Nabiximols (a cannabinoid medicine containing THC and CBD) is approved in many European countries for the treatment of neuropathic pain, spasticity and bladder dysfunction in patients suffering from multiple sclerosis. What are the potential drug interactions between nabiximols and analgesic medications?

ANSWER: The nabiximols product monograph cautions prescribers against combining nabiximols with amitriptyline or fentanyl because these drugs are metabolized by the same enzymes as nabiximols. Potential drug interactions with other opioids (oxycodone, tramadol and methadone) also exist.

–––

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: 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: 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.

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
