A systematic review and meta-analysis of 126 articles found that psychedelics—psilocybin, ayahuasca, LSD, and MDMA—reduce symptoms of depression and anxiety. Psilocybin showed the strongest therapeutic effect, followed by ayahuasca, MDMA, and LSD. Limited evidence also supports benefits for tobacco addiction, eating disorders, sleep disorders, borderline personality disorder, obsessive-compulsive disorder, and body dysmorphic disorder. The most common adverse event was headache; nearly a third of articles reported no lasting adverse effects. The findings suggest psychedelics have potential efficacy in substance-use disorders and PTSD.

A review sponsored by a public-private partnership addresses clinical trial design for new opioid use disorder (OUD) treatments that target systems other than the μ-opioid receptor. The authors present consensus recommendations for evaluating novel therapies such as cannabinoids, psychedelics, sedative-hypnotics, and immunotherapeutics. Key design elements include specifying the treatment stage (e.g., early abstinence, long-term recovery), defining the treatment's role (adjunctive or independent), selecting patient-informed primary outcomes that assess opioid use patterns, retention, and quality of life, and monitoring adverse events like relapse or overdose, especially when patients are not on maintenance opioid agonist or antagonist medications. Incorporating input from people with lived experience is urged to accelerate development and uptake of effective therapeutics.
