Benzylpiperazine (BZP)

(United Kingdom) The Medicines and Healthcare Products Regulatory Agency (MHRA) warns the public about benzylpiperazine (BZP), also called Pep Love, Cosmic Kelly and The Good Stuff. Drug dealers are selling the stuff in pill form with promises of an "herbal high."

In actuality, the drug is an anti-worming agent which can cause vomiting, abdominal pain, seizures, abnormal heart rhythms and there is an outside chance of death.
