Narcotic hypnosis or narcohypnosis is hypnosis induced by narcotics, i.e. anesthetic drugs. Instead of the regular hypnosis induction, the therapist here relies on a narcotic, which creates a state in the client that is similar to the hypnotic trance. Once this has occurred, "normal hypnosis" is performed. Narcohypnosis is not usually used in hypnosis practices today, it had its use especially in the beginning of the 20th century. If a narco-hypnosis is still used today, then by mainly in psychiatric clinics by doctors who have a license to use narcotics.
