Psychedelic Experience Survey

Data collection in this survey was completed in March 2021.

The purpose of this online survey was to improve our understanding of the acute and longer-term effects of psychedelics. These effects can be positive in some cases, but rather negative in others, depending on a multitude of factors. With their participation, nearly 2,000 people helped us to better understand the diversity of psychedelic experiences and their effects on the human mind. We sincerely thank all participants.

The results of this study were published in 2022 in the Journal of Psychopharmacology.
