Yale Program for Psychedelic Science

Research & Trials

Clinical trials conducted under FDA oversight at Yale School of Medicine. Sending an inquiry does not put you in a study and does not commit you. Whether a study is a fit is decided later, in screening, under an IRB-approved protocol. ENACT is the founding laboratory of the Yale Program for Psychedelic Science.

Our studies run in person in New Haven, and each one is looking for something specific. Other universities and hospitals run psychedelic research too.
