These kids had negative urine drug screen but were clearly under the influence of "something."
That something was K2 or Spice. at least "that's what the guy who gave it to me said it was." It's a designer drug sold legally in
K2 has an interesting history. It was invented a little over a decade ago by a John Huffman at Clemson University. Clemson's research focuses on the active ingredients in marijuana that can have medical benefits. The chemical compounds he invented -- JWH-018 and JWH - 073. When smoked or orally ingested, these chemicals produce effect similar to pot, with some users reporting dose-dependent side effects of palpitations, anxiety, vomiting and hallucinations. Not surprisingly, these creations have been taken and perverted into mind altering substances and sold legally in stores.
Asked by Chemistry World whether the compounds had any medical uses, Huffman was doubtful. "No, it's like LSD. The only thing it is good for is getting you high."
That, and maybe a visit to your local Emergency Room. Fun!
