Tablets containing mCPP confiscated by the DEA in Vernon Hills, Illinois

meta-Chlorophenylpiperazine (mCPP) is a psychoactive drug of the piperazine chemical class. It acts as a nonselective serotonin receptor agonist. Since the mid-2000s, it has been detected in pills touted as legal alternatives to illicit stimulants in New Zealand, and pills sold as ecstasy in Europe and the United States.

mCPP is known to induce headaches in humans,[1][2] and has been used for testing potential anti-migraine medications.[3] Up to 10% of people who take mCPP will develop a migraine headache, and 90% of individuals who commonly suffer from migraines will have an attack induced by mCPP. This has tended to limit the use of mCPP as a recreational drug.

Based on the recommendation of the EACD, the New Zealand government has passed legislation which placed BZP, along with the other piperazine derivatives TFMPP, mCPP, pFPP, MeOPP and MBZP, into Class C of the New Zealand Misuse of Drugs Act 1975. A ban was intended to come into effect in New Zealand on December 18 2007, but the law change did not go through until the following year, and the sale of BZP and the other listed piperazines became illegal in New Zealand as of 1st of April 2008. An amnesty for possession and usage of these drugs remained until October 2008, at which point they became completely illegal.[7]

Use in research

mCPP has been used to study the effects of the 5-HT2C receptor in the basal ganglia.[8] Studies showed that mCPP administration activates neurons in the substantia nigra pars reticula, and fails to do so in the presence of an antagonist.[9]
