K2 or Spice
K2 or “Spice” is a mixture of herbs and spices that is typically sprayed with a synthetic compound chemically similar to THC, the psychoactive ingredients in marijuana. The chemical compounds typically include HU-210, HU-211, JWH-018, and JWH-073. K2 is commonly purchased in head shops, tobacco shops, various retail outlets, and over the Internet. It is often marketed as incense or “fake weed.” Purchasing over the Internet can be dangerous because it is not usually known where the products come from or what amount of chemical is on the organic material.
