Psychedelic substances such as psilocybin, ayahuasca, LSD, and MDMA are gaining renewed medical interest due to the need for new psychiatric treatments and promising study results. This viewpoint reflects on the Royal Australian and New Zealand College of Psychiatrists' Clinical Memorandum on Psychedelics and notes regulatory developments, including applications for down-scheduling and access approvals. The authors argue that rigorous research is needed to assess benefits, safety, and therapeutic mechanisms. They summarize recent findings on mechanisms of action and the psychedelic-assisted psychotherapy model, suggesting medicinal psychedelics could become a new class of psychiatric treatments when used under medical supervision with psychotherapeutic support. However, sufficiently powered trials and safety protocols are required before clinical use, and untrained practitioner access could be harmful.

Psilocybin, a psychedelic drug, is gaining attention as a potential treatment for depression due to its mechanism of action, benefits in early trials, and relatively low side effect burden. This viewpoint outlines key unresolved issues for its clinical use: identifying which patients are most likely to benefit or experience adverse effects, understanding longer-term outcomes, and clarifying the role of psychotherapeutic support alongside the drug. There are also opportunities to better understand the neurobiology underlying its effects.

A randomized controlled trial will test the feasibility of adding behavioral activation therapy (BAT) to oral ketamine for treatment-resistant major depressive disorder. The study aims to recruit 60 adults aged 18–65 years, randomizing them to eight weeks of oral ketamine with BAT or oral ketamine alone. Feasibility will be measured by attendance, acceptability, and retention. The primary efficacy outcome is the Montgomery-Asberg Depression Rating Scale, assessed weekly during treatment and fortnightly during 12 weeks of follow-up. For a definitive trial to be recommended, the study must meet recruitment targets and show a greater than 20% reduction in relapse rates favoring the combined treatment arm.
