Psychedelic art is any art inspired by psychedelic experiences known to follow the ingestion of psychoactive drugs such as LSD and psilocybin. The word "psychedelic" (coined by British psychologist Humphry Osmond) means "mind manifesting". By that definition, all artistic efforts to depict the inner world of the psyche may be considered "psychedelic". In common parlance "psychedelic art" refers above all to the art movement of the late 1960s counterculture.
