Survey on Psychedelics and Synaesthesia

Survey on Psychedelics and Synaesthesia

This is an invitation for people to take part in a survey on the use of psychedelics (and other psychoactive substances) and synaesthesia. We are looking for people who have used psychedelics and other psychoactive substances, whether or not they have had experiences of synaesthesia, and we are looking for people who have synaesthesia, whether or not they have used psychedelics and other psychoactive substances.

Synaesthesia can be defined as experiences in which there is a blending of the senses, such as shapes having a particular taste, sounds having a particular shape, or numbers having a particular colour.

Depending on how many types of synaesthesia experience you have had, and how many different substances you have consumed, we expect this survey to take anywhere upwards from 5 minutes to complete (perhaps taking as long as 30 minutes in the extreme), although on average we expect that for most people it will take about 10-15 minutes.

Participation in this survey is completely anonymous, and has been approved by the University of Greenwich Research Ethics Committee. Please follow this link for further details and the survey:

This research may be important in helping to establish the role of psychedelics in understanding unusual perceptual phenomena and neurobiological processes involved in consciousness, so thank you for taking part. Please forward this invitation to anyone else who may be interested in responding.

If you have questions about this study please direct them to Dr David Luke:
