In its annual report, the UN Office on Drugs and Crime (UNODC) said that in Europe, seizures of new psychoactive drugs had been growing. A number of new synthetic compounds have emerged, the agency said.
The seized drugs included
piperazines, cathinones,
synthetic cannabinoids, tryptamines and phenethylamines. Piperazine was developed for the treatment of parasitic worms and as an anti-depressant. Derivatives of piperazine are often sold as ecstasy. Other examples of "new drugs" are
mephedrone, often touted as a legal alternative to amphetamine or cocaine, and "spice", a synthetic product that emulates the effect of cannabis.
