"Piperazines are frequently sold as ‘ecstasy’. Some of the generic names for these substances include, ‘pep pills’, ‘social tonics’ or simply ‘party pills’. The latter term was used to commercialize BZP in New Zealand.64 Other street names include Jax, A2, Benny Bear, Flying Angel, Legal E or Legal X, and Pep X, Pep Love or Nemesis.65 MCPP is known as 3CPP, 3C1-PP or CPP.
"Piperazines are usually available in the form of pills (regularly pressed with logos similar to ecstasy pills), capsules or loose powders, and are mainly consumed by ingestion. Liquid forms are rarely seen, but injection, smoking and snorting is also possible."
