Synthetic cannabis (
synthetic marijuana), or technically
synthetic cannabinoid receptor agonists are
designer drugs that mimic the effects of
cannabis sprayed onto a herbal base material. There are several
psychoactive artificial
cannabinoid families (e.g. AM-xxx, HU-xxx, JWH-xxx, CP xx) that are used as designer drugs sprayed on herbs and sold as natural highs under brand names like
K2 and
Spice, both of which are
genericized trademarks used for any synthetic cannabis product. Synthetic cannabis is often termed
spice product.
