Outpatient Buprenorphine Induction With Psilocybin for Opioid Use Disorder

High-dose psilocybin (30 mg) session will be administered following standard-of-care outpatient buprenorphine induction to evaluate its effect on drug abstinence, quality of life, craving, tobacco use, and treatment retention in healthy participants with an active OUD diagnosis.

A very low dose (1 mg) psilocybin session following standard-of-care outpatient buprenorphine induction will be used as a comparator arm to the high-dose psilocybin arm in evaluating psilocybin's effect on drug abstinence, quality of life, craving, tobacco use, and treatment retention in healthy participants with an active OUD diagnosis.
