This document reviews literature on the use of psychedelics like LSD, MDMA, ibogaine, and ketamine in the treatment of chemical dependency. It finds that psychedelics can contribute to successful treatment outcomes when "set and setting" are properly controlled, through better screening, preparation of clients, and environment during drug experiences. Psychedelics act as vehicles to bring unconscious contents into awareness, allowing users to gain insights and bypass ego defenses, but lasting benefits depend on individuals choosing to integrate new perspectives post-experience. More research is needed to better understand and measure psychedelic experiences and their potential while balancing Eastern and Western therapeutic approaches.
