Phencyclidine or phenylcyclohexyl piperidine (PCP), also known in its use as a street drug as angel dust among other names, is a dissociative anesthetic mainly used recreationally for its significant mind-altering effects.[1][4] PCP may cause hallucinations, distorted perceptions of sounds, and psychotic behavior.[4][7][8] As a recreational drug, it is typically smoked, but may be taken by mouth, snorted, or injected.[4][5][7] It may also be mixed with cannabis or tobacco.[1][4]
Adverse effects may include paranoia, addiction, and an increased risk of suicide, as well as seizures and coma in cases of overdose.[7] Flashbacks may occur despite stopping usage.[8]
