The Psychedelic Research Group (PRG) of Imperial College London, in collaboration with Psychedelic Survey (,) is excited to announce the launch of three large-scale online survey studies on the effects of psychedelic drugs.

Watch this promo video about our new surveys and then please do come back and read on

With these three new surveys, the Imperial team hopes to advance our understanding of the effects of psychedelics, and so help maximise safety, awareness, and wellness.

All surveys are anonymous, reaching out to people who intend to take a psychedelic drug in the near future, but each has a different focus:

  1. Global Psychedelic Survey: Are you planning a psychedelic experience using a classical psychedelic (e.g. LSD, ayahuasca, psilocybin) or related drug (e.g. Iboga/Ibogaine, salvia or Ketamine) in any kind of setting apart from an organized retreat or ceremony? Then Imperial’s Global Psychedelic Survey is your survey! For more information and to sign up, visit
  2. Microdosing Survey: Are you planning to begin a course of microdosing soon, i.e. taking very small amounts of a psychedelic over a given period of time e.g. 4 weeks? Then check out Imperial’s microdosing survey
  3. Ceremony Survey: Are you planning on participating in an organized psychedelic ceremony or psychedelic drug retreat sometime soon? If so, please consider signing up for the Psychedelic Ceremony Study, which will collect data on the psychological effects of psychedelic use in these unique settings. For more information and to sign up, visit

Thanks a lot for your support!
