BZP, or benzylpiperazine, is a synthetic compound that belongs to the piperazine family. It is often used as a recreational drug due to its stimulant effects, which can include increased energy, euphoria, and enhanced sociability. BZP is not approved for medical use and is classified as a controlled substance in several countries. The compound was first synthesized in the 1970s and gained popularity in the early 2000s as a legal alternative to other stimulants like MDMA. However, its safety profile is not well established, and users may experience side effects such as anxiety, insomnia, and increased heart rate.
