Psilocybin therapy shows promise for rapid and lasting clinical benefits when paired with psychological support, but the field lacks standardized therapeutic guidelines. A systematic review of 22 recent trials across conditions like depression, substance use, and obsessive-compulsive disorders found broad consistency in the structure of therapy sessions—before, during, and after psilocybin administration. However, trials varied widely in therapeutic intensity, diagnostic adaptations, and use of evidence-based psychotherapies. Fewer than half reported standardization measures such as manualized procedures, specific training, or adherence monitoring. These gaps undermine replicability and generalizability, and until support protocols are clearly defined, mechanistic understanding and clinical adoption will remain limited.
