["Spice"--synthetic cannabinoids with dangerous effects].

Synthetic cannabinoids are a large group of chemicals functionally related to delta-9-tetrahydrocannabinol (THC) found in Cannabis sativa. These compounds are full agonists on cannabinoid receptors, therefore more potent than THC. Products marketed over the Internet intended for abuse usually consist of dried inert plant material sprayed with different kinds of cannabinoids. Smoking is the most common route of administration. In Sweden commercially available products are usually labeled »spice«. A case concerning a young male with convulsions and acute kidney failure requiring temporary dialysis is presented. Other reported serious effects of this group of substances are acute psychosis, unconsciousness, cardiac ischemia, seizures and stroke. The vendors are very aware of the legal situation in each country and adjust their supply according to current narcotics classifications. New, previously unknown cannabinoids are constantly appearing on the market.
