Psilocybin-assisted therapy for alcoholism

There is growing evidence from small-scale clinical trials and case reports that suggest psilocybin therapy can help individuals overcome their alcohol addiction.

There are several ways in which psilocybin is believed to potentially help treat alcoholism:

  1. Psychological effects: Psilocybin has been found to have profound psychological effects, including increased feelings of well-being, spiritual experiences, and a sense of interconnectedness. These effects may help individuals struggling with alcoholism gain a new perspective on their behavior and motivations, and may help them overcome the negative patterns that led to their addiction.

  2. Reduction of alcohol cravings: Psilocybin has been shown to reduce cravings for alcohol in some individuals. This may be due to its ability to activate the serotonin 2A receptor, which has been linked to the regulation of addictive behavior.

  3. Neuroplasticity: Psilocybin has been shown to increase neuroplasticity, or the brain's ability to adapt and change. This may help individuals with alcoholism to overcome the negative effects that alcohol has on the brain and may help to reverse some of the damage caused by long-term alcohol abuse.

Latest Clinical Research

A significant study published in JAMA Psychiatry in August 2022 involving 93 participants with alcohol dependence found that two doses of psilocybin combined with psychotherapy led to:

  • Reduced drinking: An 83% reduction in heavy drinking days on average for those who took psilocybin compared to a placebo group after eight months.

  • Increased abstinence rates: The same study also showed that nearly half (48%) of those who received psilocybin therapy stopped drinking entirely eight months after the first dose, compared to only 24% in the placebo group.

Research into psilocybin-assisted therapy for alcohol use disorder has continued to expand in recent years, with several clinical trials investigating whether psilocybin may help reduce heavy drinking, cravings, and relapse risk when combined with psychotherapy and psychological support.

A 2025 open-label clinical study published in the Journal of Psychopharmacology reported that a single high dose of psilocybin, combined with psychological support, was associated with reductions in heavy drinking days, alcohol cravings, and overall alcohol consumption in participants with severe alcohol use disorder. Participants also reported increased confidence in their ability to remain abstinent.

Another 2025 randomised clinical trial investigated psilocybin-assisted psychotherapy in patients with both alcohol use disorder and depressive symptoms. Researchers reported that the treatment approach was feasible and generally well tolerated, with encouraging early signs of reduced relapse risk and improvements in mood symptoms.

Researchers have also continued to investigate whether psilocybin-assisted therapy may produce longer-term psychological changes associated with recovery from addiction. A 2025 study published in the American Journal of Psychiatry found that participants receiving psilocybin-assisted therapy demonstrated lasting reductions in impulsiveness and neuroticism, alongside increases in openness and emotional wellbeing.

At the same time, some recent studies have reported more mixed results. A 2025 phase 2 randomised clinical trial found that a single dose of psilocybin combined with brief psychotherapy did not significantly reduce relapse rates in a small group of patients with severe alcohol use disorder following withdrawal treatment, although researchers noted that larger studies are still needed.

Overall, these studies have strengthened scientific interest in psilocybin-assisted therapy as a potential future treatment option for alcohol use disorder, particularly for individuals who have not responded adequately to conventional approaches.

Important Note

Psilocybin-assisted therapy is typically combined with structured psychotherapy and psychological support, rather than being used as a standalone treatment.

While early results have been encouraging, psilocybin-assisted therapy for alcoholism remains an emerging area of research and has not yet been established as a standard treatment.
