Benzylpiperazine, often abbreviated as BZP, is a chemical compound that belongs to the piperazine family. It is primarily known for its use as a recreational drug, where it is sometimes marketed as a legal alternative to MDMA or ecstasy. BZP acts as a stimulant and can produce effects similar to those of amphetamines. In addition to its recreational use, benzylpiperazine has been studied for potential therapeutic applications. Research has explored its effects on the central nervous system, but its safety and efficacy for medical use remain under investigation. Due to its psychoactive properties, BZP is regulated in several countries.
