Percentage of Heavy Drinking Days Following Psilocybin-Assisted Psychotherapy vs Placebo in the Treatment of Adult Patients With Alcohol Use Disorder

Key finding

Psilocybin-assisted therapy significantly reduced heavy drinking days compared with active placebo over 32 weeks, suggesting potential for treating alcohol use disorder.

Institution
NYU Langone
Design
Randomized, double-blind, placebo-controlled trial
Sample size
95 participants
Intervention
Two psilocybin doses with psychotherapy vs. antihistamine active placebo
Year
2022
Condition
Alcohol use disorder
Limitations

Functional unblinding likely; the psychotherapy component makes it hard to isolate the drug effect; needs replication in larger trials.

One of the strongest controlled signals for psilocybin beyond mood disorders, extending the evidence into addiction treatment with a relatively large, placebo-controlled design.
