Brief Summary

This is an open-label pilot trial to assess the safety and feasibility of a novel 8-week psilocybin-assisted psychotherapy intervention to facilitate successful tapering/discontinuation of opioid pain medication in adult patients receiving long-term opioid therapy for chronic pain. Participation will last approximately 8 months and includes one or two psilocybin-assisted therapy sessions. The study will evaluate the incidence and severity of adverse events during and after treatment, the number of participants who drop out of the study for intervention-related reasons, and the self-reported benefits and harms of the intervention.
