Effectiveness and Experiences of Psychedelic-Based Interventions for the Treatment of Alcohol Use Disorder: A Mixed Methods Systematic Review
A mixed-methods systematic review of eight studies (four quantitative, four qualitative) examined the effectiveness and experiences of using psychedelics to treat alcohol use disorder (AUD). Quantitative studies reported an overall increase in abstinence and a decrease in drinking days after treatment, while qualitative studies reported mostly positive experiences. However, the included studies were rated mostly 'poor' or 'moderate' quality, so results should be interpreted with caution. The small number of recent studies, small sample sizes, and heterogeneity of studies limit the strength of conclusions, highlighting the need for further research.
