People who used psychedelics during the COVID-19 pandemic showed improvements in mental health. A study found that psychedelics and marijuana users showed improvements in depression, anxiety, and overall mental health. Another study found that high doses of LSD led to greater reductions in depression.

Psychedelics Lead To ‘Improvements In Anxiety And Depression During Global Crisis Times’ Like COVID Pandemic, Study Shows

People who used psychedelics during the peak of the COVID-19 pandemic
showed “improvements in mental health,” supporting the idea that
“beneficial effects on mood and anxiety associated with these substances
may extend beyond controlled conditions” that can also apply in moments of
“global crisis,” according to a new study.

Researchers at Imperial College London set out to investigate how the use
of various drugs impacted mental health outcomes amid the pandemic, drawing
on survey data from UK residents from 2019 to 2022.

On average, people who consumed drugs “had worse average mental health
scores relative to drug-naive individuals at all timepoints,” the study
found. But people who used psychedelics and marijuana “showed average
improvements in depression, anxiety and overall mental health from
pre-pandemic to January 2022, becoming on par with the drug-naive group.”

Interestingly, the study, which received support from the UK
government-funded National Institute for Health Research, said those
improvements did not appear for “cannabis-only users, whose worse mental
health scores persisted.”

“Those who used psychedelics may have experienced some improvements in
mental health across the pandemic timeframe, which supports the idea that
beneficial effects on mood and anxiety associated with these substances may
extend beyond controlled conditions,” the study authors said.

The findings were based on surveys involving 377,678 respondents between
December 2019 and March 2022. They were disaggregated into six clusters:
People who used cannabis only, cannabis and cocaine, cocaine only,
psychedelics and cannabis, poly-drug and no drugs.

“Naturalistic use of psychedelics is associated with longitudinal
improvements in anxiety and depression during global crisis times.”

“Mental health in most drug use clusters remained stable over time, except
for the psychedelics and cannabis cluster,” the study found. “At follow-up,
this cluster showed significant within-subject improvements. Comparing
pre-restrictions data to January 2022, individuals in this group had
significantly worse depression and mental health composite scores than
drug-naive individuals at baseline, but these differences diminished over
time, with no significant differences relative to drug-naive individuals
remaining at follow-up.”

“Anxiety scores also dropped significantly in this cluster, though the
differences from drug-naive individuals did not reach statistical
significance at either baseline or follow-up,” it said. “Further analyses
suggest this might be due to individuals in this cluster generally using
fewer drugs by January 2022 relative to their pre-pandemic baseline. By
contrast, cannabis-only users consistently showed poorer mental health
across all symptoms compared to drug-naive individuals, suggesting the
change in mental health scores might be related to the additional use of
psychedelics within that cluster.”

The researchers said the observation on psychedelics “accords with previous
findings that link naturalistic use of psychedelics to improved mental
health.”

The study also lays out “several pertinent explanations” for the trend.

“At the population level, drug users have worse mental health than
drug-naive individuals–and it could be that (novel) use of psychedelics,
albeit less drug use more generally, during crisis times, normalises those
differences,” it says. “Another possible explanation is that the context is
more influential in driving the effects of psychedelics than it is in
driving the effects of other drugs.”

There are limitations to the study, however. including the fact that it was
“fully automated online” so researchers “did not conduct the sorts of
interviews that are sometimes used to provide comprehensive baseline data
on participants’ drug use histories, which limits our ability to assess the
influence of prior drug use on mental health.”

“For instance, we did not collect data pertaining to dosage, frequency or
context of drug use, which are likely important in determining mental
health outcomes, nor have we gathered specific information on other drugs
individuals may use in the UK, such as amphetamines,” they said.

“Future research should investigate whether the observed changes in mental
health within the psychedelics and cannabis cluster are driven by
alterations in the use of cannabis, psychedelics or their combined effects,
particularly given their prevalent concurrent use; or whether they are a
product of other synergistic or independent factors (such as the quality of
interpersonal relationships, concurrent treatment for mood disorders or
lifestyle changes),” the study concludes.

Meanwhile, another recent study found that taking a high dose of LSD,
coupled with assisted therapy, led to “greater reductions in depression”
among patients compared to those who received a low dose of the psychedelic.

A separate scientific review on psychedelics as a possible treatment for
substance use disorders found that psilocybin-assisted psychotherapy “showed
significant reductions in alcohol consumption and high smoking cessation
rates” and has potential to lessen opioid dependence.

In 2023, meanwhile, the National Institute on Drug Abuse (NIDA) announced a $1.5
million funding round to further study psychedelics and addiction.

Other recent research has also suggested that psychedelics could unlock
promising new pathways to treat addiction. A first-of-its-kind analysis in
2023 offered novel insights into exactly how psychedelic-assisted therapy
works for people with alcohol use disorder.

Last year, meanwhile, the National Center for Complementary and Integrative
Health (NCCIH), which is part of the National Institutes of Health, identified
the treatment of alcohol use disorder as one of a number of possible
benefits of psilocybin, despite the substance remaining a Schedule I
controlled substance under U.S. law.

The agency highlighted a 2022 study that “suggested that psilocybin may be
helpful for alcohol use disorder.” The research found people who were in
psilocybin-assisted therapy had fewer heavy-drinking days over 32 weeks
than the control group, which NCCIH said “suggests that psilocybin may be
helpful for alcohol use disorder.”
