Youth Marijuana Use Remained Stable After States Started Enacting Legalization, Federal Report Finds

Published

on

A new federal report is again challenging the prohibitionist narrative that state-level marijuana legalization leads to increased youth use.

This time, the U.S. Department of Education’s National Center for Education Statistics (NCES) analyzed youth surveys of high school students from 2009 to 2019, concluding that there’s been “no measurable difference” in the percentage of those in grades 9-12 who reported consuming cannabis at least once in the past 30 days.

The report, which relies on data from the Youth Risk Behavior Surveillance System, also found that access remained stable during that time period, with no statistically significant changes in the percentage of youth who say they’ve been offered, sold or gifted illegal drugs on school grounds in the previous 30 days.

What makes the report notable is the timeline.

Cannabis reform opponents frequently argue that enacting adult-use legalization in states spur more underage people to use marijuana. There were no recreational markets in 2009, and that year, 21 percent of high school students reported past 30-day use. The first legal sales launched in Colorado in 2014—and five years after that, 22 percent of teens said they’d recently used marijuana.

The highest percentage of reported past 30-day use in this analysis actually occurred in 2011—again, before any states had legalized for adult use.

Further, there were “no measurable difference between 2009 and 2019 in the percentage of students who reported that illegal drugs were made available to them on school property,” NCES said.

Advocates have routinely pushed back against the prohibitionist argument about the relationship between state-level reform efforts and youth consumption. They maintain that establishing a regulated market, with age limits and ID requirements, allows adults to access products while creating additional barriers for underage people.

And that point has been supported by numerous studies and reports on the issue, including an earlier analysis of the same survey that was conducted by the Centers for Disease Control and Prevention. The agency found that marijuana consumption among high school students declined during the peak years of state-legal recreational cannabis legalization.

There was “no change” in the rate of current cannabis use among high school students from 2009-2019, the survey found. When analyzed using a quadratic change model, however, lifetime marijuana consumption decreased during that period.

A federally funded Monitoring the Future report released late last year found that cannabis consumption among adolescents “did not significantly change in any of the three grades for lifetime use, past 12-month use, past 30-day use, and daily use from 2019-2020.”

Another study released by Colorado officials last year showed that youth cannabis consumption in the state “has not significantly changed since legalization” in 2012, though methods of consumption are diversifying.

An official with the White House Office of National Drug Control Policy’s National Marijuana Initiative went even further last year, admitting that, for reasons that are unclear, youth consumption of cannabis “is going down” in Colorado and other legalized states and that it’s “a good thing” even if “we don’t understand why.”

Past studies looking at teen use rates after legalization have found declines in consumption or a similar lack of evidence indicating there’s been an increase.

In 2019, for example, a study took data from Washington State and determined that declining youth marijuana consumption could be explained by replacing the illicit market with regulations or the “loss of novelty appeal among youths.” Another study from last year showed declining youth cannabis consumption in legalized states but didn’t suggest possible explanations.

Dogs Are Being Exposed To Marijuana Through Human Poop And Pet Owners Should Beware, Study Finds

Published

on

A word of caution to dog owners: apparently some canines are getting intoxicated off marijuana by eating the feces of people who’ve consumed cannabis, according to a new study.

Dogs are natural scavengers, and so the instinct to eat poop—while gross—is just a fact of life. But a team of Australian researchers found that, in some cases, that instinct can become dangerous, warranting the attention of puppy parents.

The study, published in the Australian Veterinary Journal, looked at 15 cases of confirmed THC toxicosis in dogs who were suspected of, or observed to have, ingested human feces in Melbourne from 2011-2020.

The dogs presented symptoms of incoordination, dilated pupils, urinary incontinence and stupor. Urine tests from eight of the dogs showed THC metabolites in their system.

However, study author Clara Lauinger told Marijuana Moment that this shouldn’t necessarily be taken to mean that any level of THC is toxic in dogs.

“The animals in my study had ingested an unknown quantity of feces that contained an unknown concentration of THC and so one would assume this concentration would be at a level that clearly caused toxicity,” she wrote in an email. “However this does not mean that all THC ingestions can lead to toxicity.”

In fact, there are other studies where animals were administered a controlled dosage of THC and “not a single one of them displayed any adverse effects that we might see with toxicity,” she said.

“There are so so many anecdotal reports of the huge benefits that THC administration has on animals, albeit reports are from owners perception rather than peer reviewed research, but this does not mean the industry should disparage THC as a therapeutic agent,” Lauinger said.

Most of the dogs in her new study apparently ate the poop at local parks, while others ingested it at the beach, camp sites and walking trails.

“All dogs survived to discharge. Ingestion of human feces containing THC may lead to marijuana toxicosis in dogs,” the study states. “Veterinary staff and owners should be attentive in regard to using appropriate hygiene measures when managing these dogs.”

The authors said that there are a number of reasons that a dog might eat poop—or, put scientifically, engage in coprophagy. But they floated one possibility for the marijuana-specific feces-eating trend: “It is possible that the presence of marijuana in feces increases its attractiveness for ingestion by altering its scent, texture and/or taste.”

Also, while this study is limited to data on about two dozen dogs in one city of Australia, the authors also said that the habit “might be more common than what owners report,” pointing to Google search results from people reporting a dog ate feces and exhibited signs of lethargy.

The idea of dogs getting high off THC-containing human waste might seem like a stretch on its own, but the study also explains that canines have more cannabinoid receptors than humans, “making dogs more sensitive to the effects of THC.”

“In conclusion, this case series suggests that ingestion of feces produced by a human marijuana user may lead to signs of marijuana toxicosis,” the researchers said. “Clinical signs of toxicosis were similar to those previously reported for dogs with conrmed marijuana toxicosis though gastrointestinal signs were not the most common feature despite coprophagy.”

“Veterinary staff and owners should be mindful of this exposure source to ensure appropriate hygiene measures are taken when managing these dogs,” the study says.

Lauinger said that there “needs to be an industrywide understanding of the fact that there are so many different strains of cannabis and each of these strains has different cannabinoid profiles that have possible potential for beneficial therapeutic effects.”

“These strains could be researched with a focus on what ones are suitable for animals and at what dose rather than blanketing all strains as being toxic,” she said. “I hope the public can be patient and also get behind us researching the dosing more.”

While there are clear concerns about dogs ingesting excess levels of THC, studies have found promising results when it comes to the therapeutic potential of other cannabinoids like CBD for pets.

For example, dogs with epilepsy experience considerably fewer seizures when treated with CBD oil, a study published in the journal Pet Behaviour Science in 2019 found.

The prior year, a separate study determined that CBD can alleviate the symptoms of osteoarthritis in dogs.

The Food and Drug Administration (FDA), for its part, has repeatedly warned pet owners about using CBD to treat firework-related anxiety in pets around the July 4 holiday.

“You should be aware that FDA has NOT evaluated these products and can’t say whether they are safe or effective, how they are manufactured, or whether they contain CBD,” the agency said this year.

Psychedelics Use Associated With 55 Percent Decrease In Daily Opioid Consumption, Study Finds

Published

on

The use of psychedelics like LSD, psilocybin, mescaline and DMT is associated with a significant decrease in illicit opioid consumption, according to a new study.

Researchers looked at data from “three harmonized prospective cohorts of community-recruited” people with substance misuse disorders. A total of 3,813 individuals were involved, including 1,093 who reported illicit opioid consumption and 229 who said they’d used psychedelics in the past six months.

“Recent psychedelic use was associated with 55% reduced odds of daily opioid use,” the Vancouver-based study, published last week in the Journal of International Drug Policy, found.

While there have been numerous studies connecting legal marijuana access to reduced opioid use and fewer overdose deaths, this is “the first longitudinal study to link psychedelic use with lower daily opioid use,” the paper says.

“Over study follow-up after adjusting for a range of potential confounders, psychedelic use remained independently associated with a significantly reduced odds of subsequent daily opioid use,” the study states. “While confirmation in other settings is required, these findings align with growing evidence that psychedelic use may be associated with detectable reductions in subsequent substance use including illicit opioid use.”

While there’s not a clear explanation for the trend—and the researchers urged additional studies—psychedelics like psilocybin and MDMA have been touted as potentially powerful tools in mental health treatment, effectively treating conditions like severe depression, post-traumatic stress disorder and addiction.

“These findings align with growing evidence demonstrating that psychedelic use may be associated with detectable reductions in subsequent opioid use, and warrant further research on psychedelics for opioid and other substance use disorders,” the study’s lead author, Elena Argento of the University of British Columbia, told Marijuana Moment.

“This study found naturalistic psychedelic use to be independently associated with a significantly reduced odds of subsequent daily illicit opioid use among a community-based sample of [people who use drugs],” the study concluded. “More research with controlled trials and longer-term follow-up is required to elucidate the therapeutic potential of psychedelics to augment existing interventions for substance use disorders, including among more diverse populations. Additional qualitative studies would also provide opportunities to improve understanding of the possible psycho-social mechanisms underpinning psychedelic experiences.”

Another recent study found that when people use cannabis together with psychedelics, it was “associated with higher scores of mystical-type experience, ego-dissolution and visual alterations.”

With respect to marijuana alone, a study published earlier this year found that cannabis use is associated with significant reductions in dependence on opioids and other prescription drugs, as well as an increase in quality of life

Another study released last year determined that states with active medical marijuana laws saw certain opioid prescription rates drop nearly 20 percent compared to prohibition states.

Marijuana Legalization In Canada Did Not Result In Increased Traffic Injuries, Study Finds

Published

on

Canada’s move to legalize marijuana did not result in increased traffic injuries, a new study has found.

In a paper published in the journal Drug and Alcohol Dependence, researchers said they sought to investigate claims that establishing the cannabis legalization law, which took effect in October 2018, would make roads less safe, as prohibitionists frequently argue.

But after analyzing Ontario and Alberta emergency department data from April 2015 to December 2019, however, they couldn’t find any evidence to support that hypothesis.

“Implementation of the Cannabis Act was not associated with evidence of significant post-legalization changes in traffic-injury [emergency department] visits in Ontario or Alberta among all drivers or youth drivers, in particular,” the study states.

“Legalization not associated with changes in traffic injuries in all drivers or youth drivers.”

That’s despite the fact that “worldwide momentum toward legalization of recreational cannabis use has raised a common concern that such policies might increase cannabis-impaired driving and consequent traffic-related harms, especially among youth.”

The study’s lead author, Russ Callaghan, said in a press release that his team’s results “show no evidence that legalization was associated with significant changes in emergency department traffic-injury presentations.”

The researcher admitted that the outcome of the study is “somewhat surprising,” adding that he “predicted that legalization would increase cannabis use and cannabis-impaired driving in the population, and that this pattern would lead to increases in traffic-injury presentations to emergency departments.”

“It is possible that our results may be due to the deterrent effects of stricter federal legislation, such as Bill C-46, coming into force shortly after cannabis legalization,” he said, referring to a separate impaired driving bill. “These new traffic-safety laws imposed more severe penalties for impaired driving due to cannabis, alcohol, and combined cannabis and alcohol use.”

While Callaghan said he wasn’t expecting the results that his team ended up with, there is a body of existing research that’s also challenged the idea that legalization leads to increased traffic risks.

A U.S. congressional research body said in a 2019 report that concerns expressed by lawmakers that cannabis legalization will make the roads more dangerous might not be totally founded. In fact, the experts tasked by the House and Senate with looking into the issue found that evidence about cannabis’s ability to impair driving is currently inconclusive.

Other researchers have found on several occasions that traffic fatalities do not increase after a state legalizes marijuana.

A study published in the Journal of the American Medical Association late last year found that small doses of CBD appear to have no significant impact on driving, whereas comparable doses of THC were associated with short-term impairment “modest in magnitude and similar to that seen in drivers with a 0.05%” blood alcohol concentration.

In any case, House-approved report language related to funding for the Departments of Transportation, and Housing and Urban Development addresses drug-impaired driving from substances such as marijuana and urges the National Highway Traffic Safety Administration to take steps to address the issue.
