High Quality Content by WIKIPEDIA articles! Benzylpiperazine (BZP) is a recreational drug with euphoric, stimulant properties. The effects produced by BZP are comparable to those produced by amphetamine. Adverse effects have been reported following its use including acute psychosis, renal toxicity, and seizures. No deaths have been reported following a sole ingestion of BZP, although there have been at least two deaths from the combination of BZP and MDMA. Its sale is banned in a few countries, including Australia, New Zealand, the United States, the Republic of Ireland, the United Kingdom, Romania and other parts of Europe. However, its legal status is currently less restrictive in some other countries such as Canada, with investigations and regulations pending under European Union laws.
