The question in the title of this post is the headline of this effective new Leafly article, which builds off the research noted in this prior post about the "right" minimum age for legal access to recreational cannabis. Here are excerpts:
When it comes to legal cannabis, the random collection of ages across North America is curious. Every US state that allows recreational cannabis sales requires customers to be at least 21 years old. In Canada the minimum age is 19, except in Alberta (where it’s 18) and Québec (which started at 18 but raised it to 21 earlier this year).
In most jurisdictions, medical marijuana is legal for people age 18 and older, with a doctor’s recommendation.
What difference does it really make if someone is 18, 19 or 21? A research team at Memorial University in Newfoundland, Canada, recently investigated the question. Instead of looking at the immediate health and safety of young adults, they assessed later life outcomes — namely educational attainment, lifetime cigarette smoking habits, and general physical and mental health. In their study, the Memorial University team concluded that the ideal minimum legal age for cannabis was 19....
Health experts cite THC exposure in adolescents causes changes to the brain’s folding patterns, decreased neural connectivity, thinning of the cortex and lower white matter, among other symptoms. However, one recent study suggests any changes to brain structure caused by cannabis use in adolescence cleared up by the time subjects were in their 30s.
Another ongoing study in the Saguenay region of Quebec took MRI scans of over 1,000 adolescent brains in 2002, and the same subjects are currently being re-evaluated as adults — results pending.
If the serious nature of brain health is such a risk, why not just make cannabis illegal until a person’s mid-20s? In the real world, policymakers have to weigh human nature’s penchant for the forbidden with appropriate rules and consequences. In an ideal world, sure — and in this ideal world underage kids never go looking for cannabis from illicit sources, either. In the real world, though, policymakers have to weigh human nature’s penchant for the forbidden with appropriate rules and consequences. In an ideal world, alcohol would also be outlawed for health reasons, but we all know how Prohibition worked out.
Prior to the Oct. 2018 opening of legal cannabis sales in Canada, a government task force took a hard look at the best-legal-age question. That group found that the higher the minimum legal age, the more likely adolescents will seek out unregulated sources, risking both consumption of potentially more dangerous products and also incarceration.

The JAMA Internal Medicine journal has this week published online notable new original research and commentary on roadway fatalities in some states that have legalized marijuana use by all adults (called RCL in the works). Here is the main piece and its main results and conclusions from its abstract:
Implementation of RCLs was associated with increases in traffic fatalities in Colorado but not in Washington State. The difference between Colorado and its synthetic control in the post-RCL period was 1.46 deaths per 1 billion vehicle miles traveled (VMT) per year (an estimated equivalent of 75 excess fatalities per year; probability = 0.047). The difference between Washington State and its synthetic control was 0.08 deaths per 1 billion VMT per year (probability = 0.674). Results were robust in most sensitivity analyses. The difference between Colorado and synthetic Colorado was 1.84 fatalities per 1 billion VMT per year (94 excess deaths per year; probability = 0.055) after excluding neighboring states and 2.16 fatalities per 1 billion VMT per year (111 excess deaths per year; probability = 0.063) after excluding states without MCLs. The effect was smaller when using the enactment date (24 excess deaths per year; probability = 0.116).
Conclusions and Relevance
This study found evidence of an increase in traffic fatalities after the implementation of RCLs in Colorado but not in Washington State. Differences in how RCLs were implemented (eg, density of recreational cannabis stores), out-of-state cannabis tourism, and local factors may explain the different results. These findings highlight the importance of RCLs as a factor that may increase traffic fatalities and call for the identification of policies and enforcement strategies that can help prevent unintended consequences of cannabis legalization.
And here are two follow-up pieces published with this main piece:

Should the public health community applaud shifts from alcohol to marijuana (and support cannabis beverages)?
The question in the title of this post is prompted by this interesting recent Forbes piece headlined "Cannabis Taking A Larger Share Of Alcohol Industry Amid Concern Over Calories And Hangovers." Here are excerpts:
The growing concern over calories and hangovers is driving more millennials to replace alcohol with cannabis in their social life — a trend that pushes investors to increasingly eye the infused beverage industry as an opportunity.
A recent Monitoring the Future research found US millennials drink far less alcohol than previous generations: The percentage of college students who drink alcohol daily declined from 6.5% in 1980 to 2.2% in 2017. By contrast, there was a significant increase in daily marijuana use among young US adults, especially during 2019, the research further revealed, resonating with the gradual legalization of medical and recreational marijuana across the country....
Financial services company Cowen predicts the sales of recreational cannabis in the US will increase more than 700% from $6 billion in 2016 to $50 billion in 2026, prompting beverage companies of all sizes, such as Ceria, to tap into the space to grow their profits. Keith Villa, the creator of Blue Moon Brewing Company, launched Ceria in 2018 – a company produces a cannabis-infused and non-alcoholic craft beer brand Grainwave. Breweries that manufactures similar products include Colorado-based New Belgium Brewing and Dad & Dude’s Breweria, as well as SweetWater Brewing Co. of Georgia. Several mainstream CPG heavyweights, including Coca-Cola, PepsiCo and Mondelēz, also reportedly consider launching infused food products, but nothing so far has materialized.
These existing infused beverages in the market, however, do not appeal widely to consumers who are already frequent cannabis users, at least according to Jake Bullock, co-founder of cannabis-infused social tonic startup Cann. Cann produces cannabis-infused beverage products that are low in calories. “As a result, the mainstream consumer is not entering the market as quickly,” he wrote me via email, stressing the cannabis industry has lagged the growth projections many analysts and companies have made. “It is clear that cannabis is here to stay and will only continue to penetrate existing markets and new states over time,” Bullock added....
The other element that prevents more people from exploring THC-added food is their confusion with CBD products. The other co-founder of Cann, Luke Anderson, notes many consumers who are curious about cannabis turn to CBD to explore the plant, but often time, they don’t know the difference between the cannabinoids. “This has created a lot of confusion in the market, with people thinking they would 'feel something' after trying a CBD-only product and not being able to tell what was physiologically happening versus a placebo effect,” he said.
“This experience may have discouraged people from exploring micro doses of THC, which are quite safe but give you a very palpable buzz. While CBD products play in a crowded health and wellness segment of grocery aisles.”
Anderson said his company has aimed to reshape the alcohol industry with a small amount of THC in each can since it was first launched about a year ago. Cann prides itself in balancing 2 mg of sativa-dominant hybrid THC and 4mg of CBD to provide a “sessionable experience” without high calories and the hangover.
When the modern marijuana reform movement got started, I was often in the habit of saying that it would likely be a "public health win" if a lot of alcohol use was replaced by marijuana use. This article suggest this is already happening, and I presume a growing cannabis beverage market would enhance the number of folks who might substitute cannabis for alcohol. But, as the question in this post title reveals, I am not knowledgeable enough about the public health literature to say for sure that these trends ought to be applauded.

The title of this post is the title of this Hill commentary authored by Elizabeth Long and Diana Fishbein. Here are excerpts:
Despite the billions of dollars, marijuana prohibition has cost society; this strategy has failed to protect communities. Instead, it has caused great harm, particularly for marginalized populations. These adverse outcomes are rooted in policies enacted to tackle this public health problem that has little to do with public health. Marijuana possession continues to be treated as a criminal matter, even though, historically, there are no examples of criminal law solving a public health matter....
While decriminalization of marijuana is projected to have many economic and social benefits, legislation must balance decriminalization with the need to prevent teenage use. Teenage marijuana use can alter the course of brain development and increase risk for dependence and possibly addiction. Heavy use in adolescence has been associated with several developmental delays. Importantly, when teenagers believe using a drug is not harmful, they are more likely to use it....
A substantial body of research justifies reallocating resources from criminal justice to public health policies. A public health approach focuses on the implementation and enforcement of regulations to manage health risks through policy changes, such as taxation, regulation of advertising, and age limits. Several policy recommendations are offered here for consideration:
- Support a detailed, comprehensive, scientific evaluation of the impacts from current laws surrounding both medical marijuana and adult-use to guide future legislation.
- Re-categorize marijuana from Schedule I to Schedule III or IV to be more consistent with its known pharmacological properties and effects.
- Update the regulatory structure by applying uniform standards to the types of products that can be sold or marketed to the public.
- Invest prevention resources in delaying the age of initiation of marijuana use past the period when the brain is still developing (around age 25) to reduce the impact on neurodevelopment.
- Support screening, early detection, and intervention. Focus both on at-risk youth who have not yet initiated to avert pathways to use in adolescence and youth who have already begun using marijuana to avoid negative consequences.

The title of this post is the title of this notable new Washington Post commentary. I am not keen on the headline, but I am keep on the contents, especially because a Democratic Prez Candidate Debate scheduled for tonight makes this piece is a timely must-read. But that is true primarily because it is authored by Keith Humphreys, who I always consider to be a timely must-read. Here are excerpts:
When former vice president Joe Biden asserted over the weekend that marijuana shouldn’t be legal because it might be a “gateway” to hard drug use, pro-legalization critics were quick to paint him as an out-of-touch codger still fighting the last drug war. But the reaction isn’t entirely fair: Yes, the marijuana gateway theory that was omnipresent in the 1980s was at best distorted and at worst dishonest. Nevertheless, gateways between marijuana and other addictive substances are real — and they swing in both directions.
During the heyday of anti-marijuana sentiment in America, fear-based prevention programs warned adolescents that a huge percentage of adults who experienced some horrible drug-related outcome (e.g., becoming addicted to heroin) had used marijuana when they were younger. These statistics were technically accurate, but even as teenagers, most of my classmates and I could see the logical flaws in the implication that marijuana was inevitably a road to ruin. Just because most people who used heroin had previously used marijuana didn’t prove that most people who used marijuana would go on to use heroin.
But strip away that era’s ideological agenda, designed to assign marijuana a unique and powerful role in ruining lives, and a more nuanced underlying truth about gateways reveals itself. People who become users of almost any addictive substance are at higher risk of subsequently using and having problems with other substances. A recent National Academies of Sciences, Engineering, and Medicine report found moderate evidence that this is the case for cannabis, but it’s also true of other drugs, including legal ones such as alcohol and tobacco. At least three causal forces can create such gateways.
First, people can become habituated to particular routes of administering drugs....
Social networks are the second force behind drug gateways. Drug use, like many other behaviors, is very commonly a social activity. This creates gateway effects between drugs in part because classes of behavior (e.g., playing sports, traveling to exotic locales, collecting antiques or, yes, taking drugs) come to seem more normal when your friends all engage in them....
Gateways can also result from users’ desire to combine the effect of a new drug with a familiar one. Established cocaine users sometimes become heavy drinkers (and vice versa) because they find the cocaethylene produced in the body by this drug combination particularly euphoric. Similarly, the fact that many people take the trouble to carve out cigars and fill them with marijuana (known as smoking “blunts”) demonstrates that tobacco and marijuana combined is uniquely reinforcing to some users.
So those who mocked Biden’s claim that marijuana could be a gateway to other drugs thus got the science wrong. There are plenty of ways using the drug can make people more likely to use other substances.
But research also shows that singling out marijuana is wrong; the gateway effect is in fact shared by many substances. If Biden continues to oppose the legalization of marijuana on the grounds that marijuana could lead to other drugs, it is only fair that he should answer another question: Why have we made alcohol and tobacco legal and often subjected them to insufficient restrictions when they are powerful gateways, too?

The title of this post is the title of this new paper recently posted to SSRN and authored by Kathryn Foust, a recent graduate The Ohio State University Moritz College of Law. This paper is the sixteenth paper in an on-going series of student papers supported by the Drug Enforcement and Policy Center. (The fifteen prior papers in this series are linked below.) Here is this latest paper's abstract:
The intersection between marijuana and parenting is both highly controversial and largely unexplored. Despite the trend of legalization (medicinal and recreational) across the country, there is a widening discrepancy between criminal laws and child welfare policies. Even in states where marijuana is recreationally legal, a parent might still be charged with child abuse or neglect as a result of his or her marijuana use. Although second-hand marijuana smoke has proven to be a relatively low risk of harm to children, other areas of concern have not been adequately studied, such as the effects of marijuana use during pregnancy and/or breastfeeding. Despite the lack of reliable scientific studies on the impact of ingestion by children, some initial studies have shown a marked increase in frequency of accidental ingestions and resulting hospital treatment in states that have legalized marijuana. The palatability and attractiveness of “edibles” is likely the cause of this measurable and dramatic increase. Overall, parental marijuana use has been inadequately studied by science, but some reliable data is available which could be used overhaul existing children’s services policies.

The question in the title of this post is the headline if this notable new editorial in the journal Drug Discovery Today authored by Patricia Zettler and Erika Lietzan. (Disclosure/humble brag: Professor Zettler is on the Ohio State College of Law faculty and a member of our Drug Enforcement and Policy Center.) Here are excerpts from the start and end of the piece:
In the last two years the cannabidiol (CBD) market has exploded. Consumers can purchase CBD-containing oils, lotions, gummies, tea, coffee, water, popcorn, and cereal, on store shelves and online. Celebrities and athletes are touting the benefits of these products, and sales are forecast to exceed $20 billion in the next five years. This market explosion has coincided with the U.S. Food & Drug Administration (FDA)’s 2018 approval of the first CBD drug (Epidiolex), for treating seizures associated with two rare and severe forms of epilepsy in children, as well as the 2018 Farm Bill, which removed cannabis with low levels of delta-9-tetrahydocannabinol (THC) — “hemp” — from the federal list of controlled substances. And it comes on the heels of nearly 40 states enacting comprehensive laws to legalize cannabis for medical use (and sometimes recreational use) within their borders.
Yet significant questions remain about the legal status of these widely available CBD products. Most sales of CBD-containing foods and supplements violate the “drug exclusion rules” in the Federal Food, Drug, and Cosmetic Act (FDCA). But FDA has yet to enforce those rules, apart from sending warning letters to a few sellers. The agency is instead considering what approach to take. Several former agency officials — including former Commissioner Scott Gottlieb — have urged FDA to create a sensible, science-based path forward for consumer products. The time is ripe for the agency, lawmakers, health care providers, the drug discovery community, and the public to consider the purpose of the drug exclusion rules and what a different approach — exempting CBD — might mean for consumer and patient access and safety, as well as innovation incentives....
As a practical matter, CBD-containing foods and supplements may be here to stay. Lawmakers or FDA may decide that the drug exclusion rules are unwarranted for CBD, given the federal descheduling of hemp, state legalization of cannabis products, and (eventually) rigorous evidence that CBD products are relatively safe. But FDA should not default into this position simply because a robust, albeit unlawful, market has already emerged. A decision to give CBD special treatment should be made thoughtfully and with public participation, accounting for possible gains in consumer access and choice, as well as the lost opportunity to learn, and harness, CBD’s full therapeutic potential.

The title of this post is the title of this notable new article authored by Elena Andreyeva and Benjamin Ukert published in the Forum for Health Economics & Policy. Here is its abstract:
Growing evidence suggests that medical marijuana laws have harm reduction effects across a variety of outcomes related to risky health behaviors. This study investigates the impact of medical marijuana laws on self-reported health using data from the Behavioral Risk Factor Surveillance System from 1993 to 2013. In our analyses we separately identify the effect of a medical marijuana law and the impact of subsequent active and legally protected dispensaries.
Our main results show surprisingly limited improvements in self-reported health after the legalization of medical marijuana and legally protected dispensaries. Subsample analyses reveal strong improvements in health among non-white individuals, those reporting chronic pain, and those with a high school degree, driven predominately by whether or not the state had active and legally protected dispensaries. We also complement the analysis by evaluating the impact on risky health behaviors and find that the aforementioned demographic groups experience large reductions in alcohol consumption after the implementation of a medical marijuana law.
"Cannabinoids for the treatment of mental disorders and symptoms of mental disorders: a systematic review and meta-analysis"
The title of this post is the title of this notable new article by multiple authors published in The Lancet Psychiatry. Here is its "Summary":
Medicinal cannabinoids, including medicinal cannabis and pharmaceutical cannabinoids and their synthetic derivatives, such as tetrahydrocannabinol (THC) and cannabidiol (CBD), have been suggested to have a therapeutic role in certain mental disorders. We analysed the available evidence to ascertain the effectiveness and safety of all types of medicinal cannabinoids in treating symptoms of various mental disorders.
For this systematic review and meta-analysis we searched MEDLINE, Embase, PsycINFO, the Cochrane Central Register of Controlled Clinical Trials, and the Cochrane Database of Systematic Reviews for studies published between Jan 1, 1980, and April 30, 2018. We also searched for unpublished or ongoing studies on ClinicalTrials.gov, the EU Clinical Trials Register, and the Australian and New Zealand Clinical Trials Registry. We considered all studies examining any type and formulation of a medicinal cannabinoid in adults (≥18 years) for treating depression, anxiety, attention-deficit hyperactivity disorder (ADHD), Tourette syndrome, post-traumatic stress disorder, or psychosis, either as the primary condition or secondary to other medical conditions. We placed no restrictions on language, publication status, or study type (ie, both experimental and observational study designs were included). Primary outcomes were remission from and changes in symptoms of these mental disorders. The safety of medicinal cannabinoids for these mental disorders was also examined. Evidence from randomised controlled trials was synthesised as odds ratios (ORs) for disorder remission, adverse events, and withdrawals and as standardised mean differences (SMDs) for change in symptoms, via random-effects meta-analyses. The quality of the evidence was assessed with the Cochrane risk of bias tool and Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. This study is registered with PROSPERO (CRD42017059372, CRD42017059373, CRD42017059376, CRD42017064996, and CRD42018102977).
83 eligible studies (40 randomised controlled trials, n=3067) were included: 42 for depression (23 randomised controlled trials; n=2551), 31 for anxiety (17 randomised controlled trials; n=605), eight for Tourette syndrome (two randomised controlled trials; n=36), three for ADHD (one randomised controlled trial; n=30), 12 for post-traumatic stress disorder (one randomised controlled trial; n=10), and 11 for psychosis (six randomised controlled trials; n=281). Pharmaceutical THC (with or without CBD) improved anxiety symptoms among individuals with other medical conditions (primarily chronic non-cancer pain and multiple sclerosis; SMD −0·25 [95% CI −0·49 to −0·01]; seven studies; n=252), although the evidence GRADE was very low. Pharmaceutical THC (with or without CBD) worsened negative symptoms of psychosis in a single study (SMD 0·36 [95% CI 0·10 to 0·62]; n=24). Pharmaceutical THC (with or without CBD) did not significantly affect any other primary outcomes for the mental disorders examined but did increase the number of people who had adverse events (OR 1·99 [95% CI 1·20 to 3·29]; ten studies; n=1495) and withdrawals due to adverse events (2·78 [1·59 to 4·86]; 11 studies; n=1621) compared with placebo across all mental disorders examined. Few randomised controlled trials examined the role of pharmaceutical CBD or medicinal cannabis.
There is scarce evidence to suggest that cannabinoids improve depressive disorders and symptoms, anxiety disorders, attention-deficit hyperactivity disorder, Tourette syndrome, post-traumatic stress disorder, or psychosis. There is very low quality evidence that pharmaceutical THC (with or without CBD) leads to a small improvement in symptoms of anxiety among individuals with other medical conditions. There remains insufficient evidence to provide guidance on the use of cannabinoids for treating mental disorders within a regulatory framework. Further high-quality studies directly examining the effect of cannabinoids on treating mental disorders are needed.

"Contribution of Marijuana Legalization to the U.S. Opioid Mortality Epidemic: Individual and Combined Experience of 27 States and District of Columbia"
The title of this post is the title of this new forthcoming research article authored by Archie Bleyer and Brian Barnes. Here is its abstract:
Prior studies of U.S. states as of 2013 and one state as of 2015 suggested that marijuana availability reduces opioid mortality (marijuana protection hypothesis). This investigation tested the hypothesis with opioid mortality trends updated to 2017 and by evaluating all states and the District of Columbia (D.C.).
Opioid mortality data obtained from the U.S. Centers for Disease Control and Prevention were used to compare opioid death rate trends in each marijuana-legalizing state and D.C. before and after medicinal and recreational legalization implementation and their individual and cumulative aggregate trends with concomitant trends in non-legalizing states. The Joinpoint Regression Program identified statistically-significant mortality trends and when they occurred.
Of 23 individually evaluable legalizing jurisdictions, 78% had evidence for a statistically-significant acceleration of opioid death rates after medicinal or recreational legalization implementation at greater rates than their pre-legalization rate or the concurrent composite rate in non-legalizing states. All four jurisdictions evaluable for recreational legalization had evidence (p <0.05) for subsequent opioid death rate increases, one had a distinct acceleration, and one a reversal of prior decline. Since 2009-2012, when the cumulative-aggregate opioid death rate in the legalizing jurisdictions was the same as in the non-legalizing group, the legalizing group′s rate accelerated increasingly faster (p=0.009). By 2017 it was 67% greater than in the non-legalizing group (p<0.05).
The marijuana protection hypothesis is not supported by recent U.S. data on opioid mortality trends. Instead, legalizing marijuana appears to have contributed to the nation′s opioid mortality epidemic.

The title of this post is the headline of this AP article, which started this way:
Public health officials in Oregon said Wednesday that a person who recently died of a severe respiratory illness had used an electronic cigarette containing marijuana oil from a legal dispensary, the second death linked to vaping nationwide and the first tied to a vaping product bought at a pot shop.
Officials have not determined what sickened the middle-aged adult, whether the product was contaminated or whether they may have added something to the liquid in the device after buying it, said Dr. Ann Thomas with the Oregon Health Authority.
Thomas declined to name the brand of the product or the dispensary during the investigation and said it's the only case of vaping-related illness or death in Oregon that authorities know about. "Our investigation has not yielded exactly what it is in this product," Thomas said. "At this point, some of the other states have more data than us."
As of last week, 215 possible cases of severe lung disease associated with the use of e-cigarettes had been reported by 25 states, according to the federal Centers for Disease Control and Prevention. The battery-powered vaping devices can be used to inhale a flavored nicotine solution or a solution infused with marijuana oil.
Illinois officials on Friday reported what they consider the first death in the nation linked to vaping after the person contracted a serious lung disease. They didn't say if the e-cigarette contained marijuana oil or just nicotine. Health officials in some states have said a number of people who got sick had vaped products containing THC, the compound that gives marijuana its high.
That's a critical distinction in the Oregon case, according to the American Vaping Association, which has blamed the recent spate of lung illnesses on illegal vape pens that contain THC.
Wisconsin public health officials said late last month that 89% of the people they interviewed who became sick reported using e-cigarettes or other vaping devices to inhale THC.
In New York state, 32 cases of vaping-related illness have been reported, with a "vast majority" involving people who vape illicit marijuana. None has involved medical marijuana products sold in compliance with state law.
New York officials are focusing their investigation on an additive used in black-market vape oils made from vitamin E. A state health department spokeswoman said a lab has found "high levels" of vitamin E acetate in "nearly all" the marijuana samples involved.

This morning, the federal government weighed in on the health risks of marijuana reforms through this new extended US Surgeon General advisory headed "Marijuana Use and the Developing Brain." Here is how it gets started and some key passages (with lots of cites to research removed):
I, Surgeon General VADM Jerome Adams, am emphasizing the importance of protecting our Nation from the health risks of marijuana use in adolescence and during pregnancy. Recent increases in access to marijuana and in its potency, along with misperceptions of safety of marijuana endanger our most precious resource, our nation’s youth.
Marijuana, or cannabis, is the most commonly used illicit drug in the United States. It acts by binding to cannabinoid receptors in the brain to produce a variety of effects, including euphoria, intoxication, and memory and motor impairments. These same cannabinoid receptors are also critical for brain development. They are part of the endocannabinoid system, which impacts the formation of brain circuits important for decision making, mood and responding to stress....
The risks of physical dependence, addiction, and other negative consequences increase with exposure to high concentrations of THC7 and the younger the age of initiation. Higher doses of THC are more likely to produce anxiety, agitation, paranoia, and psychosis. Edible marijuana takes time to absorb and to produce its effects, increasing the risk of unintentional overdose, as well as accidental ingestion by children and adolescents. In addition, chronic users of marijuana with a high THC content are at risk for developing a condition known as cannabinoid hyperemesis syndrome, which is marked by severe cycles of nausea and vomiting.
This advisory is intended to raise awareness of the known and potential harms to developing brains, posed by the increasing availability of highly potent marijuana in multiple, concentrated forms. These harms are costly to individuals and to our society, impacting mental health and educational achievement and raising the risks of addiction and misuse of other substances. Additionally, marijuana use remains illegal for youth under state law in all states; normalization of its use raises the potential for criminal consequences in this population. In addition to the health risks posed by marijuana use, sale or possession of marijuana remains illegal under federal law notwithstanding some state laws to the contrary.
Marijuana Use during Pregnancy
Pregnant women use marijuana more than any other illicit drug. In a national survey, marijuana use in the past month among pregnant women doubled (3.4% to 7%) between 2002 and 201712. In a study conducted in a large health system, marijuana use rose by 69% (4.2% to 7.1%) between 2009 and 2016 among pregnant women. Alarmingly, many retail dispensaries recommend marijuana to pregnant women for morning sickness.
Marijuana use during pregnancy can affect the developing fetus. THC can enter the fetal brain from the mother’s bloodstream and may disrupt the endocannabinoid system, which is important for a healthy pregnancy and fetal brain development. Moreover, studies have shown that marijuana use in pregnancy is associated with adverse outcomes, including lower birth weight. The Colorado Pregnancy Risk Assessment Monitoring System reported that maternal marijuana use was associated with a 50% increased risk of low birth weight regardless of maternal age, race, ethnicity, education, and tobacco use....
Marijuana Use during Adolescence
Marijuana is also commonly used by adolescents, second only to alcohol. In 2017, approximately 9.2 million youth aged 12 to 25 reported marijuana use in the past month and 29% more young adults aged 18-25 started using marijuana. In addition, high school students’ perception of the harm from regular marijuana use has been steadily declining over the last decade. During this same period, a number of states have legalized adult use of marijuana for medicinal or recreational purposes, while it remains legal under federal law. The legalization movement may be impacting youth perception of harm from marijuana.
The human brain continues to develop from before birth into the mid-20s and is vulnerable to the effects of addictive substances. Frequent marijuana use during adolescence is associated with changes in the areas of the brain involved in attention, memory, decision-making, and motivation. Deficits in attention and memory have been detected in marijuana-using teens even after a month of abstinence. Marijuana can also impair learning in adolescents. Chronic use is linked to declines in IQ, school performance that jeopardizes professional and social achievements, and life satisfaction. Regular use of marijuana in adolescence is linked to increased rates of school absence and drop-out, as well as suicide attempts.

The title of this post is the headline of this new commentary in the New York Times authored by two doctors, Kenneth L. Davis and Mary Jeanne Kreek. Here are excerpts:
It’s tempting to think marijuana is a harmless substance that poses no threat to teens and young adults. The medical facts, however, reveal a different reality.
Numerous studies show that marijuana can have a deleterious impact on cognitive development in adolescents, impairing executive function, processing speed, memory, attention span and concentration. The damage is measurable with an I.Q. test. Researchers who tracked subjects from childhood through age 38 found a consequential I.Q. decline over the 25-year period among adolescents who consistently used marijuana every week. In addition, studies have shown that substantial adolescent exposure to marijuana may be a predictor of opioid use disorders.
The reason the adolescent brain is so vulnerable to the effect of drugs is that the brain — especially the prefrontal cortex, which controls decision making, judgment and impulsivity — is still developing in adolescents and young adults until age 25....
The risk that marijuana use poses to adolescents today is far greater than it was 20 or 30 years ago, because the marijuana grown now is much more potent. In the early 1990s, the average THC content of confiscated marijuana was roughly 3.7 percent. By contrast, a recent analysis of marijuana for sale in Colorado’s authorized dispensaries showed an average THC content of 18.7 percent.
The proposals for legalizing marijuana under consideration in New York and New Jersey allow for use starting at age 21. While society may consider a 21-year-old to be an adult, the brain is still developing at that age. States that legalize marijuana should set a minimum age of no younger than 25. They should also impose stricter limits on THC levels and strictly monitor them. Educational campaigns are also necessary to help the public understand that marijuana is not harmless.
Simply because society has become more accepting of marijuana use doesn’t make it safe for high school and college students. Cigarettes and alcohol, both legal, have caused great harm in society as well as to people’s health, and have ruined many lives. Marijuana may do the same. We must tightly regulate the emerging cannabis industry to protect the developing brain.
UPDATE: Interestingly, not long after blogging about this NY Times commentary, I came across this extended Washington Post piece headlined "Potent pot, vulnerable teens trigger concerns in first states to legalize marijuana." Here is a snippet:
As more than a dozen states from Hawaii to New Hampshire consider legalizing marijuana, doctors warn of an urgent need for better education — not just of teens but of parents and lawmakers — about how the products being marketed can significantly affect young people’s brain development.
The limited scientific research to date shows that earlier and more frequent use of high-THC cannabis puts adolescents at greater jeopardy of substance use disorders, mental health issues and poor school performance.
“The brain is abnormally vulnerable during adolescence,” said Staci Gruber, an associate professor of psychiatry at Harvard Medical School who studies how marijuana affects the brain. “Policy seems to have outpaced science, and in the best of all possible worlds, science would allow us to set policy.”

The leading medical marijuana advocacy group, Americans for Safe Access, has this terrific new resource titled "Patient's Guide To CBD." Though the title of this nearly 50-page report is simple, the contents provide an intricate road-map to the complicated law and science surrounding the status and import of the cannabis-plant compound known as CBD. Here is a section of the publication's introduction:
The Patient’s Guide to CBD was created by Americans for Safe Access (ASA) for the benefit of patients, prospective patients, healthcare providers, consumers, and anyone interested in learning more about CBD. The goal of this guide is to be an informative and useful reference document that will be shared with others so that patients, doctors, and regulators can make informed decisions regarding CBD....
Patients and consumers should also be aware of the legal and regulatory status of CBD products. As of May 2019, 47 U.S. states have passed some type of legislation permitting the use of cannabis or cannabinoids such as CBD; nevertheless, cannabis with THC in excess of 0.3% by dry weight is a Schedule I controlled substance under U.S. Federal law. Therefore, CBD-containing products that were produced from cannabis plants that exceed the federal threshold on THC may be legal at the state level, but are federally illegal. Additionally, even CBD products that are derived from plants containing not more than 0.3% THC by dry weight may violate laws such as the Food, Drug and Cosmetics Act and create further legal challenges for patients and consumers.
The passage of the Agriculture Improvement Act of 2018 (also known as the 2018 Farm Bill) will make industrial hemp (i.e., cannabis with no more than 0.3% THC by dry weight), including CBD-rich industrial hemp, an agricultural commodity in the United States, but the U.S. Department of Agriculture has yet to promulgate federal regulations or approve state regulations regarding the cultivation and processing of industrial hemp. Further, the U.S. Food & Drug Administration has yet to provide a pathway for the introduction of hemp-derived CBD products into the marketplace. Therefore, it is not yet federally legal to market hemp-derived CBD as a drug, dietary supplement, food product, or cosmetic. Patients and consumers are encouraged to stay up to date on these changing regulations to ensure that they, and their products, are in compliance with applicable laws.
Globally, the use of products containing CBD has risen dramatically as more and more people seek alternative ways to improve their health and their lives. The data has shown an increase in the sales of products containing CBD every year, and sales are expected to continue to rise in the coming years.

Long-time readers know I have long been covering the (never-quite-clear) connection between modern marijuana reform and the modern opioid crisis. (Just some of many, many prior posts on this front are linked below.) Today brings notable research news on this front, which is already getting a lot of attention from the mainstream press in articles from CNN, from NBC News, from Newsweek, and from US News & World Report, among others. All these stories are about a new study published in The American Journal of Psychiatry from multiple authors under this catchy title: "Cannabidiol for the Reduction of Cue-Induced Craving and Anxiety in Drug-Abstinent Individuals With Heroin Use Disorder: A Double-Blind Randomized Placebo-Controlled Trial." Here is the study's abstract:
Despite the staggering consequences of the opioid epidemic, limited nonopioid medication options have been developed to treat this medical and public health crisis. This study investigated the potential of cannabidiol (CBD), a nonintoxicating phytocannabinoid, to reduce cue-induced craving and anxiety, two critical features of addiction that often contribute to relapse and continued drug use, in drug-abstinent individuals with heroin use disorder.
This exploratory double-blind randomized placebo-controlled trial assessed the acute (1 hour, 2 hours, and 24 hours), short-term (3 consecutive days), and protracted (7 days after the last of three consecutive daily administrations) effects of CBD administration (400 or 800 mg, once daily for 3 consecutive days) on drug cue–induced craving and anxiety in drug-abstinent individuals with heroin use disorder. Secondary measures assessed participants’ positive and negative affect, cognition, and physiological status.
Acute CBD administration, in contrast to placebo, significantly reduced both craving and anxiety induced by the presentation of salient drug cues compared with neutral cues. CBD also showed significant protracted effects on these measures 7 days after the final short-term (3-day) CBD exposure. In addition, CBD reduced the drug cue–induced physiological measures of heart rate and salivary cortisol levels. There were no significant effects on cognition, and there were no serious adverse effects.
CBD’s potential to reduce cue-induced craving and anxiety provides a strong basis for further investigation of this phytocannabinoid as a treatment option for opioid use disorder.

The question in the title of this post is prompted by this notable story out of Boston headlined "Harvard, MIT share $9 million gift to study marijuana's health effects." Here are the interesting details:
An investor in the cannabis industry has donated $9 million to Harvard and MIT to study the drug’s health effects, in what the institutions describe as the largest private gift to support marijuana research in the United States. The Broderick Fund for Phytocannabinoid Research, announced Tuesday morning, will be shared equally by Harvard Medical School and the Massachusetts Institute of Technology, with the goal of filling vast gaps in the understanding of how marijuana affects the brain and behavior.
“The lack of basic science research enables people to make claims in a vacuum that are either anecdotal or based on old science,” said the donor, Charles R. “Bob” Broderick, an alumnus of both universities. “For generations we haven’t been able to study this thing for various sorts of societal reasons. That should end now, as well as the prohibitions that are falling around the world.”
Broderick has invested heavily in the booming marijuana business, starting in Canada in 2015 and more recently the United States, through his family-run Uji Capital. Although Broderick stands to profit if the studies find benefits from marijuana, the universities and the researchers said the donor will have no say in the work process or its results. They also pledged to publish their findings even if they find marijuana doesn’t help or causes harm.
Broderick recalled the first time he raised the idea of funding cannabis research with a Harvard development officer: “There was silence on the other end. Then she said, ‘I don’t think we do it.’ And I said, ‘That’s the problem.’ ” The official soon called back to say that Harvard researchers studying brain chemicals would be interested in examining marijuana’s effects.
Dr. Igor Grant, a longtime California marijuana researcher who is not involved with the Harvard-MIT project, said the grant “will really let them move forward with research that has been difficult to fund.”
“The work in this area has been very, very slow coming,” said Grant, director of the Center for Medicinal Cannabis Research at the University of California San Diego.
“This is exactly the type of research we need,” said Dr. Peter Grinspoon, a Massachusetts primary care doctor and board member of Doctors for Cannabis Regulation, a group promoting legalization and regulation of marijuana. Whether for or against marijuana, Grinspoon said, “Everybody wants more research.” The marijuana studies to date vary in quality, often have conflicting results, and typically involve either purified extracts or smoked marijuana — not the gummies, cookies, vapor, oils, or highly potent buds that people consume today....
Until recently researchers could work only with marijuana grown at a federal farm in Mississippi, whose plants are less potent than those purchased at dispensaries in states where the drug is legal. But John Gabrieli, a professor of brain and cognitive sciences at MIT and one of the grant recipients, said “a fast-changing regulatory environment” is allowing access to better material.
The MIT researchers intend to use extracts from the plants to tease out the effects of marijuana in people with schizophrenia — about half of whom are heavy cannabis users, Gabrieli said. The researchers want to pursue intriguing evidence that a component in marijuana known as tetrahydrocannabinol, or THC, improves cognitive function in people with schizophrenia. They will look at how THC as well as another key component — cannabidiol, or CBD — affect cognition alone and in combination.
Another MIT researcher will study how chronic exposure to THC and CBD may alter the cell types implicated in schizophrenia, potentially shedding light on why teens who use cannabis are at greater risk of developing schizophrenia and why the drug may be more dangerous for teens than adults.
Other studies at MIT will examine whether marijuana ingredients can help people with autism and with Huntington’s disease, and will study the effects of cannabis ingredients on attention and working memory. It’s been “incredibly hard” to get funding for marijuana research, Gabrieli said. “It’s been illegal all over the place until very recently. Without the philanthropic boost, it could take many years to work through all these issues.”
At Harvard, the $4.5 million gift establishes the Charles R. Broderick Phytocannabinoid Research Initiative, involving some 30 basic scientists and clinicians at the medical school and its affiliated hospitals. The Harvard team plans to study the effects of marijuana ingredients on brain cell function and the connections between brain cells, testing purified ingredients on mice and rats.
Researchers at Harvard have been studying natural brain chemicals known as endocannabinoids, which are involved in a variety of functions, including memory, appetite, and stress response. The grant will enable them to expand that research to encompass cannabinoids derived from plants. “Marijuana has about 100 different cannabinoid compounds. We understand very little about the specific effects of each of them on the nervous system,” said Bruce Bean, Harvard neurobiology professor and one of the project’s researchers....
The research, however, is funded by someone who could profit if the findings are favorable or lose money if new dangers are discovered. Could knowing this somehow, even unconsciously, bias the results? Josephine Johnston, director of research at the Hastings Center, a think tank concerned with bioethics, said such conflicts of interest are commonplace. “In a pure world, you wouldn’t have a situation like this. But it’s pretty much a fact of life of biomedical research in the United States that you have interested parties funding research,” said Johnston, co-editor of a book on conflicts of interest in biomedical research. Institutions can enact safeguards to ensure both that the research is unbiased and that it’s perceived as trustworthy.
Both MIT and Harvard said they have such policies in place, requiring that gifts come without strings attached and that researchers have control over their work and its publication. Grant, the California marijuana researcher, agreed that conflict of interest is an important concern. But, he added, if people profiting from the marijuana boom invest in science, “maybe that’s not a bad thing. They could just as easily buy yachts or do something else.”
Because I am a kind of marijuana researcher (focused on law and social science, rather than medical science), I realize I have a bias when suggesting that everyone involved in the marijuana industry ought to be funding academic marijuana research. Also, as a director of the Drug Enforcement and Policy Center at The Ohio State University, I am sensitive to the concern that research funded by the marijuana industry or investors carries real conflict risks that can come with any private funding of public research.
All that said, this article helps highlight just some of the many reasons why a lot more private funding (and a lot more public funding) is needed for all sorts of marijuana research. There are many times I end up feeling truly overwhelmed by all the important research questions that arise in this space and all the formal and informal barriers to conducting all the needed research. And especially with so many legal and social changes in this space, this period seems like an "all hands on deck" moment. And I do not think it is misguided to believe that everyone involved in the marijuana industry and especially its investors ought to be swabbing the deck as best they can.

"The Effect of Marijuana Use on American Veterans with PTSD, and How the U.S. Department of Veterans Affairs Ought to Respond"
The title of this post is the title of a presentation to be made by one of my students in my Marijuana Law, Policy & Reform seminar this coming week. Here is part of his explanation of his topic and links to some background reading:
Because the U.S. Department of Veterans Affairs (VA) is required to follow all federal laws, the VA is prohibited from prescribing, recommending, or assisting veterans in obtaining marijuana. While veterans may discuss marijuana use with VA providers, VA doctors cannot help their patients participate in a state medical marijuana program and veterans cannot obtain reimbursement funding through the VA when they seek medical marijuana from state programs.
The inability of the VA to prescribe or recommend marijuana to American veterans with PTSD denies former service members an opportunity to receive treatment that many veterans not only want, but which also has the potential to be safer than the VA’s history of doling out addictive prescription drugs such as opioids, antidepressants, and anti-anxiety pills. PTSD is a serious disease that is relatively common among combat veterans — it causes varying symptoms such as flashbacks, nightmares, severe anxiety, and uncontrollable thought about a triggering event.
The medical research in this arena has reached mixed findings. While some researchers have found that the use of medical marijuana by veterans with PTSD has positive results, other studies suggest that marijuana use by those with PTSD may actually make symptoms worse. There simply has not been enough controlled studies to conclusively state whether marijuana is beneficial for those with PTSD. Nonetheless, there is plenty of anecdotal evidence by veterans suggesting that their use of marijuana has improved, or in some cases eliminated, symptoms associated with their PTSD. Fortunately, the first clinical trial of marijuana for American veterans with PTSD is currently underway in Colorado. My presentation will suggest that we need more controlled clinical trials such as this to further identify whether marijuana could (or should) truly be used as a remedy for veterans with PTSD.

"The contribution of cannabis use to variation in the incidence of psychotic disorder across Europe (EU-GEI): a multicentre case-control study"
The title of this post is the title of this important new study appearing in The Lancet Psychiatry. Here is its summary:
Cannabis use is associated with increased risk of later psychotic disorder but whether it affects incidence of the disorder remains unclear. We aimed to identify patterns of cannabis use with the strongest effect on odds of psychotic disorder across Europe and explore whether differences in such patterns contribute to variations in the incidence rates of psychotic disorder.
We included patients aged 18–64 years who presented to psychiatric services in 11 sites across Europe and Brazil with first-episode psychosis and recruited controls representative of the local populations. We applied adjusted logistic regression models to the data to estimate which patterns of cannabis use carried the highest odds for psychotic disorder. Using Europe-wide and national data on the expected concentration of Δ9-tetrahydrocannabinol (THC) in the different types of cannabis available across the sites, we divided the types of cannabis used by participants into two categories: low potency (THC <10%) and high potency (THC ≥10%). Assuming causality, we calculated the population attributable fractions (PAFs) for the patterns of cannabis use associated with the highest odds of psychosis and the correlation between such patterns and the incidence rates for psychotic disorder across the study sites.
Between May 1, 2010, and April 1, 2015, we obtained data from 901 patients with first-episode psychosis across 11 sites and 1237 population controls from those same sites. Daily cannabis use was associated with increased odds of psychotic disorder compared with never users (adjusted odds ratio [OR] 3·2, 95% CI 2·2–4·1), increasing to nearly five-times increased odds for daily use of high-potency types of cannabis (4·8, 2·5–6·3). The PAFs calculated indicated that if high-potency cannabis were no longer available, 12·2% (95% CI 3·0–16·1) of cases of first-episode psychosis could be prevented across the 11 sites, rising to 30·3% (15·2–40·0) in London and 50·3% (27·4–66·0) in Amsterdam. The adjusted incident rates for psychotic disorder were positively correlated with the prevalence in controls across the 11 sites of use of high-potency cannabis (r = 0·7; p=0·0286) and daily use (r = 0·8; p=0·0109).
Differences in frequency of daily cannabis use and in use of high-potency cannabis contributed to the striking variation in the incidence of psychotic disorder across the 11 studied sites. Given the increasing availability of high-potency cannabis, this has important implications for public health.

From the Akron Beacon Journal, "Ohio medical marijuana recommendations coming from clinics, not family doctors"
If you know someone who has received a recommendation to use medical marijuana, odds are the recommendation didn’t come from a family doctor or primary-care physician. The vast majority of recommendations in Ohio come from clinics that employ doctors solely to evaluate patients for medical marijuana, say people familiar with the industry....
“Marijuana-specific clinics fill a huge need,” said Dr. Joel Simmons, who runs the Ohio Herbal Clinic, a Near East Side cannabis clinic. While the clinics, many of which have out-of-state owners, have some critics, patient advocates say primary-care doctors are the ideal source for marijuana recommendations.
Those doctors better understand a patient’s needs and medical history, said Mary Jane Borden, co-founder of the Ohio Rights Group, which advocates for users of medicinal cannabis. When Ohio lawmakers wrote the state’s medical-marijuana law, they hoped that family physicians would be writing most recommendations, Borden said....
Clinics charge between $125 and $200 for an evaluation, which insurance won’t cover. Because the clinics don’t negotiate with insurance companies, they clinics can charge whatever they want, said Emilie Ramach, founder and CEO of Compassionate Alternatives, a Columbus-based nonprofit agency that helps patients pay for medicinal cannabis. Several clinic doctors, including Simmons, said they do their best to keep their prices reasonable.
From the Columbus Dispatch, "High prices keep many Ohioans out of legal cannabis market"
As Ohio’s medical marijuana industry finally takes off, some patients and advocates are griping about costs that put it out of reach for many people. A steep price tag stems partly from the lack of competition, as Ohio only has seven dispensaries spread throughout the state, mostly in rural areas, experts said. Costs are expected to drop as more dispensaries open and the industry finds its footing.
In the meantime, patients openly acknowledge buying the drug on the black market while they wait for prices to come down. And without insurance to cover the expense, some worry that low-income people might never be able to afford medical cannabis....
Several local patients said using marijuana has improved their quality of life, but they must stretch their budgets to pay for it or buy it on the street. “I’m not using as much as I probably need to be using,” said Mary Alleger, 31, of Reynoldsburg, who said she uses cannabis to treat post-traumatic stress disorder (PTSD) and ongoing pain from a botched medical procedure.
Katherin Cottrill, 33, of Newark, has worked with the patient advocacy organization Ohio Rights Group to acquire a medical marijuana card, but said current costs keep her from even getting started. “I would have to pay $200 to $250 (just to get a recommendation),” Cottrill said. “And then I have to drive to a dispensary and pay $50. It’s unreasonable for me to even try.”...
Just under 3 grams of medical marijuana costs about $50. Cannabis clinics charge between $125 and $200, and the state charges $50 in fees. Marijuana is cheaper on the street, patients said.
“On the black market you can buy an ounce for $200,” said Robert Doyle, 61, of Newark, who has a medical marijuana card but still buys the drug on the street due to the cost. There are about 28 grams in an ounce. Doyle said he’s visited dispensaries in Michigan with prices comparable to the black market, making him confident that Ohio’s costs will eventually fall....
But even if prices drop, clinic costs and fees will remain a barrier for some, Cottrill said. “What about low-income people who are desperately seeking medication?” she said. “They can’t even afford to pay $50 to get their card registered.”
