Objectives: This study investigates psychedelic drugs to treat substance use disorder (SUD). Researchers have recently begun conducting clinical trials of psychedelic treatment for SUD. The current meta-analysis investigates the extent of efficacy in alleviating SM behaviours (P) using psychedelic therapy (I), concurrent with determining which psychedelic enables the greatest effect (C) as a treatment tool for reducing SUD (O). Methods: The inclusion criteria in this study include evaluating the efficacy of LSD, psilocybin, ketamine, or ibogaine in human beings with an SUD. The exclusion criteria include studies on rodents, patients with schizophrenia, case studies, incomplete or ongoing trials, and studies with insufficient quantitative data. The search criteria obtained 1278 articles, acquired through PubMed and PsycINFO. After excluding literature, 30 papers were kept in the final meta-analysis. A random-effects model analysis was applied to investigate individual psychedelic interventions, with a corresponding combined psychedelic intervention analysis. Results: The results favoured psychedelics as an SM treatment, with ibogaine evidencing the most prominent. We also found a non-significant difference between the effectiveness of psychedelic treatment paired with psychotherapy and psychedelic treatment alone. This study aims to contribute knowledge to future clinical research on the psychedelic treatment of SUD.
