This reading and study group will meet weekly for 12 weeks, and maintain the same membership for the 12 week period. The group will have a syllabus with papers or chapters that participants are expected to read. The format will include a short review of a selected paper by the group leader, followed by discussion of the content and related matters. This group will not be a forum for case presentations or extended sharing, either personal or clinical. The group is open to all, but will assume that members are interested in studying the academic literature on psychedelics from clinical, psychological, anthropological and philosophical points of view. We are asking Reading Group members to commit to the full 12-week series upon registration.
