The Integration of the Psychedelic Experience


Since the psychedelic renaissance gained momentum, the main focus of research has been on unraveling and understanding the acute effects of psychedelics, on the one hand, and on figuring out how best to use psychedelics in the treatment of specific mental disorders, on the other. However, less attention has been paid to the aftermath: how people deal with psychedelic experiences, how they affect and change their lives, and what factors are helpful for successful integration into everyday life. Based on the practical experience as a psychedelic therapist and an informal survey of former patients, the typical course of integration of psychedelic experiences is described, as well as the circumstances and tools that were found to be helpful.
