Clinical Trials Map

The results of clinical trials suggest that psychedelics could be used for a range of therapeutic purposes, but figuring out how to participate in psychedelic-assisted therapy as either a therapist or a patient can be complicated. BCSP’s clinical trials map, featuring data from, provides a way to navigate past, ongoing and future trials.
