Someone today in an online game i was playing was asking. "Has anyone ever smoked spice"? Another replied that it made holes in your brain! So i was wondering what is it? a new drug around? so i had to research it:
Synthetic cannabis is a psychoactive herbal and chemical product which, when consumed mimics the effects of cannabis. It is best known by the brand names K2 and Spice, both of which have largely become genericized trademarks used to refer to any synthetic cannabis product. (It is also for this reason that synthetic cannabis is often referred to as spice product, due to the latter.)
It's been around since the mid-'90s, when John Huffman, a Clemson University chemist, synthesized a substance he called JWH-018. The chemical was structurally similar to THC, the active ingredient in pot, and apparently quite a bit more potent. (There's a good explanation of the science here.) Like its illicit cousin, JWH-018 made users mellow and euphoric. Pot enthusiasts picked up on Huffman's work, mixed or bought batches of JWH-018 themselves, and started spraying it onto varying mixes of dried herbs, flowers, and tobacco leaves. The result was K2—a.k.a. "Spice," "Genie," or "Zohai"—which quickly caught on in head shops and on the Internet as a way to get high without breaking the law.
