Piperazines

BZP can come in different coloured pill form and is also sold as an off-white powder, in capsules and as a liquid. It is therefore usually swallowed.

The stimulant effects of BZP are similar to ecstasy but dose for dose BZP is not as potent. Effects can last for 6 – 8 hours. With decreased appetite and sleeplessness. Users often suffer a severe hangover-like reaction that can last for up to 24 hours.

Short term:

Agitation, vomiting, stomach pain, fits, irregular heart rhythms, diarrhoea, allergic reactions and fever have all been reported.

Long term:

BZP is a stimulant drug, which makes it particularly risky if taken by anyone suffering from high blood pressure or heart condition. Perfectly healthy young people can have a fit or heart attack after taking stimulant drugs. And you may not know that you have a pre-existing heart condition.

Mixing BZP with amphetamines (like ecstasy and speed) and alcohol can be very dangerous. In rare cases users may suffer from serotonin syndrome, which can cause high blood pressure and may be fatal.

Benzylpiperazine (BZP) and related compounds such as mCPP, DBZP, TFMPP and others are Class C controlled drugs. This means that it is against the law to possess them, to give them away or to sell them. Possession can get you up to two years in prison and/or an unlimited fine. Supplying someone else, even your friends, can get you up to fourteen years in prison and/or an unlimited fine.
