The IMPRINT Survey at University College London: Integrating Meditation and Psychedelic Research Initiative
"The IMPRINT survey marks the beginning of a research programme interested in deepening and refining the dialogue between meditation and psychedelic research. The data we collect will further our understanding of the relationship between meditation practice preferences, personality traits, and the use of psychedelics. No psychedelic experience is required for participation." See here to participate and for further information.
