The link between cannabis concentrates and psychosis | Guest View

By Lauren Davis, published in the Edmonds Beacon, February 18, 2021

In 2012, Washington voters approved Initiative 502, legalizing cannabis. Back then, the black market was dominated by dried cannabis flower, with a potency of approximately 10%.

Dried cannabis flower is biologically limited to about 30% potency, and I-502 capped the potency of edibles at 10%.

But in an oversight of extraordinary proportions, there was no potency limit established for cannabis concentrates like THC-infused vape oils, shatter, and dab wax. Enter science, industry, business investors, and profit motivation and, today, concentrates with 99 percent potency are readily available at cannabis retailers.

According to researchers, these concentrates are “as close to the cannabis plant as strawberries are to Frosted Strawberry Pop-Tarts.” Cannabis concentrate sales have soared from 14% of the market share in 2015 to 37% in 2019.

I have devoted my professional and legislative career to mental health and substance use prevention, treatment, and recovery.

Spurred by reports of youth with cannabis-induced psychosis filling emergency departments and psychiatric wards and high school students having psychotic episodes after dabbing (inhaling), I began to delve into the research on cannabis and psychosis.

The literature is both definitive and damning. Washington’s leading cannabis experts at the University of Washington and Washington State University recently released a consensus statement summarizing the science:

“High potency cannabis use can have lifelong mental health consequences, which often manifest in adolescence or early adulthood. Daily cannabis use, particularly of high potency products, increases the risk of developing a psychotic disorder, like schizophrenia, and is related to an earlier onset of symptoms compared to people who do not use cannabis.”

During the 2020 legislative session, I introduced a bill to cap the potency of cannabis concentrates at 10%. This figure matched the limit for edibles and was a starting point for negotiation. The bill included an exemption for patients using high potency concentrates for medical purposes.

I had numerous meetings with cannabis industry representatives, and no one was aware of the psychosis link. Though they disagreed with my proposed solution, industry leaders were emphatic in their commitment to coming to the table as thoughtful partners to address this issue.

So, you can imagine my surprise when, instead of proposing more palatable policy solutions as promised, cannabis industry representatives testified before the House Commerce & Gaming committee that the research implicating cannabis in psychotic disorders is unfounded.

Borrowing from the well-worn playbooks of their forefathers, big tobacco and opioid manufacturers, cannabis business leaders attempted to poke holes in the science and offer alternative explanations.

In 1957, tobacco industry director Clarence Cook Little wrote: “No one has established that cigarette smoke, or any one of its known constituents, is cancer-causing to man.”

Sixty-three years later, cannabis industry leaders testified to our legislature that “cannabis use [is] not independently associated with psychosis.”

Modeling after Purdue Pharma, the opioid maker that wrote that addiction “is not caused by drugs … it is triggered in a susceptible individual by exposure to drugs,” the cannabis industry tried to offer a counter theory – that it is people who have a genetic predisposition for psychotic disorders who are developing them and then using cannabis to self-medicate.

That theory has been debunked by studies that account for family history and still show a significant increase in psychotic disorders from cannabis use.

I never anticipated the cannabis industry would enthusiastically agree to a low potency limit. I only expected them to make good on their word – to show up as earnest partners in addressing their product’s role in one of the largest emerging health crises of our time.

When the industry’s opening move is to spit on the consensus of the scientific community in the spirit of climate deniers, it’s difficult not to question the sincerity of their espoused commitment to public health.

I’ve introduced House Bill 1463, which caps the potency of cannabis concentrates at 30% and raises the age of purchase for concentrates from 21 to 25. Washington’s cannabis industry now has a second chance to act with integrity and come to the table as problem solvers.

It is only the fate of our children with which we are gambling.

Updates on the Marijuana Psychosis Link

Researchers at the University of Pittsburgh and Rutgers University have issued a correction to their original report that teen marijuana use had no effect on the development of a psychotic order by age 36.

Meanwhile, a hospital in Washington, the first state to legalize marijuana, reports 1-2 new cases of admissions for marijuana-induced psychosis each day.

The full length version of their published correction, which can be purchased for ~$11 online, reveals that in fact their data showed a trend towards a 2.5-fold greater prevalence of psychotic disorders in the marijuana users, a trend which reached significance in a “one-tailed” statistical test.  Such a test is generally deemed appropriate if abundant prior studies have shown the same degree and direction of effect, as is the case here.

Civil Rights, Drug Wars, Policy, Washington, DC

(Part 2 , see Part 1 – Our first article is about why African-Americans are less supportive of legalization than outsider groups who are trying to impose it on Washington, DC and elsewhere.)

Discussion of marijuana legalization centers mainly on personal freedom, flaws in the criminal justice system, and a theory that government can regulate it and take profits away from cartels and criminals.  There is no evidence that it is possible to regulate marijuana, and black markets persist in Washington and Colorado.  Since the regulation theory has largely been disproven by the two states and by studies, this article concentrates on criminal justice.

Can anyone truly believe legalizing marijuana would end racial discrimination in America? (Recent evidence in Denver and Seattle after the legalization of marijuana in Seattle suggests that racial discrepancies in arrests don’t end.)  However, these disparities are the main reasons people cite for supporting legalization of pot in Washington, DC.

Taking on the ACLU Positions

Metropolitan Police Chief Cathy L Lanier addressed the racial divide in arrests in the Washington Post.  Some of her comments specifically responded to a American Civil Liberties Union (ACLU) report.

“The ACLU also appears not to understand our city very well,” she wrote. “It is, indeed, a sad fact that blacks represent a disproportionate number of arrestees in the District; the proportions are similar for marijuana arrests, for other narcotics and all arrests.  But this is a complex issue that cannot be boiled down to an allegation that MPD (Metropolitan Police) selectively enforces the law against our black communities.”

Lanier points out that police in certain neighborhoods received a higher volume of calls from residents complaining about drugs, and that 59% of the police officers are black, a proportion higher than the city’s population.  Blacks are arrested more for marijuana because they tend to smoke it in public among groups, unlike whites who more often smoke in the privacy of their residence or clubs.

Cathy Lanier is the most popular citywide public figure in Washington, DC, with an approval rating over 70%.

Drug Policy in General

Chief Lanier emphasized that the police department in Washington, DC, is strongly committed to supporting youth.  The goal is to prevent youths from ending up in the criminal justice system for a minor transgression. Since she has been in the police department for 24 years and chief of police for seven, she has first-hand knowledge which the ACLU lacks.  She realizes that where there is already criminal activity, trying to put the marijuana under regulations may mean that criminals would branch out to other forms of crime and selling other drugs.

Much of the country agrees with rehabilitating drug addicts and drug abusers, rather than punishment.  While states vary, the drug treatment model is becoming more prevalent.   Transforming our drug policy rather than adopting complete tolerance and normalization of drugs  is a wiser policy.  The answer is not legalization.

We need a non-partisan national discussion, that considers all sides of the issue.  Mandatory minimum sentences don’t accomplish the goals desired when they were established. Three strikes laws should be abolished.  Prisons-for-profit aren’t allowed in most of the country, but they could also be banned.

“War on Drugs” Rhetoric

The idea that the “war on drugs” is a war on black and Hispanic communities is too simplistic to explain a situation.   The ACLU, which has had an important stake in legalization efforts in Maine and Washington (2 states with low African-American and Hispanic populations), uses this arguments to press legalization of drugs.

Wealthy white drug dealers can probably afford more expensive lawyers than minority drug dealers, a different matter.  Black males have been disproportionately jailed for violating drug laws.  Michelle Alexander, who wrote The New Jim Crow, supports legalization of all drugs.  However, she is now lamenting that legalization has benefited the white males who are now making all the profits.

The cause of racial problems of the United States and drug violence in Central America shouldn’t be seen as one-dimensional issues.  The argument that the violence of drug gangs and cartels is caused by US policy shows a lack of understanding of the nature of drugs.

The drug policy – violence theory also demonstrates a poor understanding of the nature of humanity.  Gangs and cartels are money-making paths that bring profits quickly.  Anyone can be lured into the profit motive without fully thinking of the harm, particularly when a person is young and risky behaviors make it seem exciting.  There is a certain “high” that comes from evading the law.

Criminal businesses will be always be attractive to both the rich and the poor.  Some cartel leaders are well-educated and even rich.  If it were only about income inequality, many would get out of the drug trade sooner.  We need to foster opportunities for the poor, so they don’t see drug dealing as a route out of poverty.  Regardless of circumstances, they’re hungry for power and wouldn’t lose power over people, if pot became legal. They would branch out to other crimes such as human trafficking, and to other drugs.

 When Drug Wars Occur

Drug wars happen when growers and cartels compete to have the strongest, most potent strains of marijuana.   High-THC plants bring higher profits, but the marijuana industry pretends that government is to blame for the greedy, violent wars between drug cartels.

We can see the violence that comes with the competition in the drug trade in the book and movie, Savages of 2012, with Benicio del Toro.  An earlier movie  Blow, in which Johnny Depp played notorious drug dealer George Jung, tries to illicit sympathy for the criminal who was instrumental in bringing the Columbian cocaine trade to the USA.  It is clear that greed and adventure motivated Jung, without concern about the harmful consequences to others.

Marijuana advocates who say “drug wars don’t work,”  play into current anti-government sentiments.  They say those who don’t agree with marijuana must be taking money from the drug-making companies, the police unions, alcohol industry, the prison or prison guard industry.  Otherwise, how could anyone not believe in their psychotropic drug that has been manipulated — to become stronger and to work medical miracles, as they claim? In their twisted logic, they say the US has created cartel violence in Mexico. Violence of course has many causes including poverty.   On the other hand, there is evidence that cartels have moved out of Colorado into Central America, and are causing our heroin epidemic today.
