Psychedelics Can Help Patients With Depression And Anxiety, Study Finds

Published

on

Amidst the growing global movement to decriminalize certain psychedelic drugs, a new scientific review found that ayahuasca, psilocybin and LSD may help with two of the most common psychiatric disorders in the world.

“In all studies,” the paper’s authors write, “psychedelic administration caused statistically significant reductions in depression and anxiety symptoms. These findings corroborate the limited previous research conducted in animal studies and healthy volunteers, as well as anecdotal evidence describing improved mood and reduced feelings of apprehension following psychedelic administration.”

“In a supportive setting, ayahuasca, psilocybin, and LSD consistently produced immediate and significant anti-depressant and anxiolytic effects that were endured for several months.”

Researchers in London analyzed seven prior studies with a total of 130 patients who had been diagnosed with depression and/or anxiety. One looked at the effects of ayahuasca for major depressive disorder, one measured how LSD helped with anxiety linked with a potentially deadly disease and five used psilocybin as an intervention for treatment-resistant depression, anxiety and depression associated with life-threatening and advanced-stage cancers.

Here’s what the review’s authors found:

  • In a small study of six patients, a single dose of ayahuasca reduced test scores measuring depressive symptoms by up to 82 percent at one, seven and 21 days after intake.
  • Patients who participated in a study investigating the efficacy of psilocybin for treatment-resistant depression saw their symptoms “significantly improved from baseline to 1 week and 3 months post-treatment, with maximum effect at 2 weeks.” A follow-up study at six months found “the anti-depressant and anxiolytic effects of psilocybin were sustained and remained significant at 6 months post-treatment.”
  • Three more double-blind, placebo-controlled cross-over trials involving psilocybin had similar positive results in reduction of symptoms associated with anxiety and depression linked to life-threatening cancer.
  • In another small study, 12 patients with anxiety associated with the fear that they might die because of a disease were treated with drug-free psychotherapy sessions and two psychotherapy sessions that involved either an experimental dose of LSD (200 micrograms) or a smaller, placebo dose of LSD (20 micrograms). At their two-month follow-up assessment, patients who received the experimental dose reported their symptoms were “significantly reduced,” and these results were still evident at 12 months.

In short: Psychedelics appeared to help patients manage their anxiety and depression better.

“These improvements were consistently observed across a variety of rating scales, and this is suggestive of a genuine therapeutic effect rather than a specific scale’s tendency to show a positive effect,” the study states. “Moreover, the lack of equivalent symptom reduction in control patients indicates that the anti-depressant and anxiolytic effects can be attributed to psychedelic intervention.”

The authors also found that many patients “described the experience as spiritually meaningful, resulting in decreased disease-related demoralisation and hopelessness as well as improved quality of life.”

Importantly, researchers found that the psychedelic treatment “was well-tolerated with no persisting adverse effects.” The most common short-term side effects they reported included transient anxiety, headaches, nausea, in addition to mild increases in heart rate and blood pressure.

“Given the limited success rates of current treatments for anxiety and mood disorders, and considering the high morbidity associated with these conditions,” the study’s authors conclude, “there is potential for psychedelics to provide symptom relief in patients inadequately managed by conventional methods. The novelty of this research means that before psychedelics’ wider-use can be contemplated, the results presented herein need to be replicated in larger studies with a longer followup to determine lasting efficacy and safety.”

The review, published online in the Journal of Affective Disorders last week, comes just two months after the Food and Drug Administration and the National Institutes of Health sent a letter to a senator that acknowledges the potential healing properties of certain psychedelic substances. The federal agencies noted, however, that they have no plans to reclassify any psychedelics currently in the restrictive category of Schedule I, such as psilocybin, LSD and MDMA.

FDA Clears Researchers To Study MDMA Use By Therapists Being Trained In Psychedelic Medicine

Published

on

The Food and Drug Administration (FDA) has already authorized clinical trials into the therapeutic potential of MDMA for patients with post-traumatic stress disorders—but now it’s given the green light to a psychedelics research institute to expand its studies by administering the substance to certain therapists.

Volunteer therapists who are being trained to treat people with PTSD will be able to participate in the Phase 1 trials to gain personal experience with the treatment option. This is a complementary research project that comes as the Multidisciplinary Association for Psychedelic Studies (MAPS) is in the process of conducting Phase 3 trials involving people with the disorder.

The development comes months after Canadian regulators announced that certain therapists would be allowed to take psilocybin in order to gain a better understanding of the psychedelic when treating patients.

MAPS sought permission to proceed with the therapist-specific trials in 2019, but FDA placed them on a 20-month hold because of concerns about the merits, risks and credentials of investigators. MAPS appealed that hold, providing evidence about the study’s scientific value and ability of its staff, and FDA cleared them on Tuesday.

The organization “chose to dispute” FDA’s hold not just because of the impact it had on the planned studies, “but in an attempt to resolve an ongoing issue with the FDA regarding investigator qualifications across studies,” it said in a press release on Wednesday.

“While the term ‘dispute’ may seem adversarial, this process can actually strengthen the relationship and trust between us and our review Division and ensures the Division has support on this project from the [FDA] Office of Neuroscience,” MAPS Public Benefit Corporation (PBC) CEO Amy Emerson said. “This decision demonstrates how our strategic, data-driven strategy in challenging the FDA rulings can be successful.”

Now MAPS is able to launch the Phase 1 clinical trials into MDMA-assisted therapy for therapists.

It will be designed to “measure development of self-compassion, professional quality of life, and professional burnout among clinicians delivering the treatment to patients,” the association said.

Getting personal experience with the substance “is widely considered to be an important element in preparation and training to deliver psychedelic-assisted therapies.”

This will “support the goals of the MDMA Therapy Training Program to provide comprehensive training to future providers,” and it “builds capacity to deliver quality, accessible care to patients, pending approval of MDMA-assisted therapy as a legal prescription treatment,” MAPS PBC Director and Head of Training and Supervision Shannon Carlin said.

FDA first granted MAPS’s request for an emergency use authorization for MDMA in PTSD in 2017. The organization expects to complete its Phase 3 trails in 2022.

The scientific expansion move also comes as the psychedelics decriminalization movement continues to build in the U.S.

Frequent Marijuana Consumers Are Actually More Physically Active Than Non-Users, Study Finds, Smashing Stereotypes

Published

on

In a stereotype-busting new study, researchers found that frequent marijuana consumers are actually more likely to be physically active compared to their non-using counterparts.

For decades, anti-cannabis propaganda has cast marijuana consumers as unmotivated couch potatoes. This government-funded ad is a perfect example:

But a study published in the Harm Reduction Journal on Thursday found the opposite to be true. A nationally representative analysis of accelerometer-measured sedentary behavior showed that people who frequently use marijuana—particularly those aged 40 and older—spend more time engaging in physical activity than non-users do.

“Our findings do not support the mainstream perception of cannabis users as living sedentary lifestyles,” the researchers concluded.

In general, they found that “there’s no significant differences between non-current cannabis users and light, moderate, or frequent cannabis users in minutes per day spent in [sedentary behavior].” The difference came down to the average minutes that each group spent in physical activity.

“After controlling for all covariates, frequent cannabis users engaged in significantly greater amounts of light [physical activity] and [moderate-to-vigorous physical activity] compared to non-current users,” the study states. “In the unadjusted model, moderate cannabis use predicted more minutes spent in [moderate-to-vigorous physical activity] compared to non-current use, but this association was not significant upon controlling for all covariates. Light cannabis users did not significantly differ from non-current users in time engaged in [physical activity.”

“The results suggest that frequent cannabis users engaged in more [physical activity] than non-current users, but spent similar amounts of time in [sedentary behavior],” the researchers said.

While the study indicated that light marijuana use is not associated with a statistically significant difference in time being physically active, those who infrequently use cannabis were more likely to self-report more moderate physical activity compared to non-users.

“In a national, population-based US sample, current cannabis use was significantly associated with accelerometer-measured [physical activity], such that frequent cannabis users engaged in greater minutes of light PA and [moderate-to-vigorous physical activity] compared to non-current users.”

The researchers also looked at the relationship between marijuana use, activity and age, finding that people over 40 who consumed cannabis moderately spent an average of 16 more minutes engaged in moderate physical activity each day than non-users.

To explain that trend, the study suggests that cannabis “is being used for exercise-induced pain recovery, since [physical activity] brings about pain and muscle soreness, and a decreased pain threshold and muscle hypersensitivity have been documented with increasing age.”

These findings “add to the cannabis and physical behavior literature by incorporating objective accelerometer measures,” the researchers concluded. “Further understanding of the association between cannabis use and health behaviors is essential to fully addressing the public health concerns associated with cannabis use.”

Legal Marijuana States See Reduced Workers’ Compensation Claims, New Study Finds

Published

on

Legalizing marijuana for adult use is associated with an increase in workforce productivity and decrease in workplace injuries, according to a new study partly funded by the federal government.

In a working paper published by the National Bureau of Economic Research, researchers looked at the impact of recreational cannabis legalization on workers’ compensation claims among older adults. They found declines in such filings “both in terms of the propensity to receive benefits and benefit amount” in states that have enacted the policy change.

Further, they identified “complementary declines in non-traumatic workplace injury rates and the incidence of work-limiting disabilities” in legal states.

These findings run counter to arguments commonly made by prohibitionists, who have claimed that legalizing marijuana would lead to lower productivity and more occupational hazards and associated costs to businesses. In fact, the study indicates that regulating cannabis sales for adults is a workplace benefit by enabling older employees (40-62 years old) to access an alternative treatment option.

“We offer evidence that the primary driver of these reductions [in workers’ compensation] is an improvement in work capacity, likely due to access to an additional form of pain management therapy,” the study, which received funding from the National Institute on Drug Abuse, states.

The implementation of adult-use legalization seems to “improve access to an additional channel for managing pain and other health conditions, suggesting potential benefits on populations at risk of workplace injuries,” it continues.

The study is based on an analysis of data on workers’ compensation benefit receipt and workers’ compensation income from
2010 to 2018 as reported in the Annual Social and Economic Supplement of the Current Population Survey.

“Our results show a decline in workers’ compensation benefit propensity of 0.18 percentage points, which corresponds to a 20 percent reduction in any workers’ compensation income, after states legalize marijuana for recreational use. Similarly, we find that annual income received from workers’ compensation declines by $21.98 (or 20.5%) post-[recreational marijuana legalization]. These results are not driven by pre-existing trends, and falsification exercises suggest that observing estimates of this magnitude is statistically rare.”

Researchers said that they’ve found evidence that cannabis use increases post-legalization among the age cohort they studied, but no such spike in misuse. Further, they found a decline in post-legalization prescriptions for medications used to treat chronic pain, indicating that some people are using marijuana as a substitute for traditional painkillers.

“We hypothesize that access to marijuana through [recreational marijuana laws] increases its medical use and, in turn, allows better management of symptoms that impede work capacity—e.g., chronic pain, insomnia, mental health problems, nausea, and so forth,” the study says. “Chronic pain management is likely to be particularly important in our context as this is the health condition most commonly reported among medical marijuana users.”

Beyond decreasing workers’ compensation claims and costs, legalization also is a boon to the economy by adding jobs in legal states.

The cannabis industry added more than 77,000 jobs over the past year—a 32 percent increase that makes the sector the fastest in job creation compared to any other American industry, according to a report released by the cannabis company Leafly last week.
