Rolicyclidine (PCPy) is a dissociativeanesthetic that is similar in effects to phencyclidine, but is slightly less potent and has fewer stimulant effects.[1] It instead produces a sedative effect described as being somewhat similar to a barbiturate, but with additional PCP-like dissociative, anaesthetic and hallucinogenic effects.[2] Due to its similarity in effects to PCP, PCPy was placed into the Schedule I list of illegal drugs in the 1970s, although it has never been widely abused and is now little known.
