BZP is a common name for the synthetic drug N-benzylpiperazine, a stimulant that is approximately 10 to 20 times more potent than amphetamine.
BZP tablets, especially those that also contain the hallucinogen TFMPP (1-(3-trifluoromethylphenyl)piperazine), often are sold as MDMA (3,4-methylenedioxymethamphetamine, also known as ecstasy) or promoted as an alternative to MDMA.
BZP is illegal. In March 2004 the DEA designated BZP a Schedule I substance under the Controlled Substances Act.
