Summary
Psychedelic therapy shows remarkable promise in treating alcohol use disorder, with patients twice as likely to achieve sobriety or significantly reduce drinking when treated with LSD or similar compounds. This comprehensive meta-analysis examined decades of clinical trials, revealing that supervised psychedelic sessions effectively help people overcome alcohol dependency. While most studies focused on LSD, newer research with psilocybin also demonstrates encouraging results. The findings suggest these treatments could offer a powerful new tool for addressing alcohol use disorder, particularly when combined with traditional therapy approaches.
Abstract
Critique the available systematic review and de novo assessment of the role of psychedelics in the treatment of alcohol use disorder. A systematic literature search of PubMed was completed from 1960 to 9/9/2023. We pooled randomized controlled trials comparing psychedelics to control therapy for the treatment of alcohol use disorder. At the first recorded follow-up, LSD [n = 3, Odds Ratio (OR) 1.99 (95% Confidence interval (CI): 1.10 to 3.61)] and any psychedelic [n = 4, OR 2.16 (95%CI: 1.26 to 3.69)] enhanced the odds of patients achieving abstinence or a substantial reduction in drinking alcohol versus placebo in randomized, double-blind, placebo-controlled trials. When the inclusion criteria were relaxed to include controlled trials without double-blinding or placebo control, LSD [n = 5, OR 1.79 (95%CI: 1.36 to 2.34)] and any psychedelic therapy [n = 6, OR 1.89 (95%CI: 1.42 to 2.50)] still enhanced the odds of patients achieving abstinence or a substantial reduction in drinking alcohol. Four of 6 trials had high risk of bias and other methodological issues. One trial found an instance of suicidal ideation as well as transient increases in blood pressure that requires further exploration before the balance of benefits to harms can be determined. The use of psychedelics to treat alcohol use disorder is promising, but the weaknesses in the literature base preclude making definitive statements about its value. Future trials with greater methodological rigor are needed.
