Born in Veracruz, Salvador Roquet was a beloved psychiatrist who worked with different shamans and healers throughout Mexico between the years of 1967 and 1974; he trained many psychedelic therapists in his approach, and worked with over 1,700 patients. He developed very intense methods of conducting group psychedelic sessions with powerful impact. He was known to sometimes use adverse stimuli to induce psychologically difficult states of mind in his patients while they were under the influence of various psychedelics including psilocybin-containing mushrooms, peyote, datura, ketamine, and LSD. In 1974, Roquet was charged with drug trafficking and crimes against the health of his patients. The charges were dropped on April 30, 1975, after a Supreme Court trial. Following this incident, Roquet began to instead work with his own drug-free spin on the humanistic Psychosynthesis therapy first developed by Roberto Assagioli. Roquet combined this with increased sensory stimulation, Gestalt therapy, psychodrama, the creation of art, bioenergetics, Reichian massage, and other processes.
