Benocyclidine, also known as benzo​thiophenyl​cyclo​hexylpiperidine (BTCP), is a psychoactive recreational drug of the arylcyclohexylamine class which is related to phencyclidine (PCP). It was first described in a patent application naming Marc Caron and colleagues at Duke University in 1997.[1]

It acts as a potent and selective dopamine reuptake inhibitor (DRI) and a psychostimulant.[2][3] Unlike related compounds like phencyclidine and ketamine, benocyclidine is a pure DRI with negligible affinity for the NMDA receptor, and it therefore lacks any anticonvulsant, anesthetic, hallucinogenic, or dissociative effects.[2][3] It has been used to label the dopamine transporter.[4][5] BCP was used to try to find a common pharmacophore for DRI type stimulants.[6]

More recently, benocyclidine has been found in several ecstasy tablets, sold as MDMA.[7]
