Treatment with Ketamine or ECT in the current episode is also exclusionary.

Patients will be followed for 12 weeks following the psilocybin exposure. The initial screening visit is about 3 hours, the psilocybin exposure day will be 8 hours and all other visits will be between 30min and 3 hours long. Seven psychotherapy sessions will be conducted as part of the psilocybin treatment. There is the possibility an 8-month extension follow-up phase after the 18-week study. Study will provide $50 compensation per study visit.
