Piperazine

MBZP is a stimulant1 in the piperazine chemical class and a derivative of benzylpiperazine.2 Its effects resemble those of benzylpiperazine, with slightly weaker stimulation and an apparently lower tendency to cause headaches and nausea. It may be habit-forming. MBZP has been sold as an ingredient in recreational products known as “party pills,” first in New Zealand and later in other countries.
