Health Behavior Change Through Psychedelics:


An International Survey

This is a retrospective study of the relationship between psychedelic experiences and changes in physical activity, diet and several other health-related behaviors.


We are interested in investigating the characteristics of planned or unplanned changes in these behaviors and the circumstances in which they occurred, in relation to past psychedelic experiences. Anyone who has taken a psychedelic substance can participate by filling out a single online questionnaire.

This study is being conducted in partnership with researchers from the Center for Psychedelic and Consciousness Research at Johns Hopkins University, the Unit of Cognitive Psychology at Leiden University, the Center for Psychedelic Research at Imperial College London, and Columbia University.


This study is part of a Doctoral Dissertation and has received approval from the Faculty of Human Kinetics' research ethics committee.

Why participate?

Data from this study will contribute to a better understanding of the behavioral and psychological effects of psychedelic experiences.


We need input from a wide variety of people, across the world, who have used psychedelics.
