Introduction: Phencyclidine, a dissociative anesthetic with hallucinogenic effects, is commonly abused as a recreational drug. Phencyclidine analogs are compounds produced by substitutions of the phenyl and piperidine rings of phencyclidine. Illegal use of phencyclidine and its analogs has symptoms such as addiction, confusion, and increased tendencies toward violence.
