Psychedelic therapy refers to therapeutic practices involving the use of psychedelic drugs, particularly serotonergic psychedelics such as LSD, psilocybin, DMT, mescaline, and 2C-B, primarily to assist psychotherapy. As an alternative to synonyms such as "hallucinogen", "entheogen", "psychotomimetic" and other functionally constructed names, the use of the term psychedelic ("mind-manifesting") emphasizes that those who use these drugs as part of a therapeutic practice believe these drugs can facilitate beneficial exploration of the psyche. In contrast to conventional psychiatric medication which is taken by the patient regularly or as-needed, in psychedelic therapy, patients remain in an extended psychotherapy session during the acute activity of the drug and spend the night at the facility. In the sessions with the drug, therapists are nondirective and support the patient in exploring their inner experience. Patients participate in psychotherapy before the drug psychotherapy sessions to prepare them and after the drug psychotherapy to help them integrate their experiences with the drug.
