"The United States Drug Enforcement Administration (DEA) exercised its emergency scheduling authority to extend, by six months, control of five chemicals (JWH-018, JWH-073, JWH-200, CP-47,497, and cannabicyclohexanol) used to make so-called “fake pot” products," states the D.E.A. in a release Fed. 29.
JWH and company are burly synthetic cannabinoids created in labs, manufactured in China and un-tested on humans. People are using them to get high and pass a drug test, especially groups regularly drug tested for marijuana, like servicemembers, athletes, and as the D.E.A. relates below, teens and young adults. Their maker, chemist John W. Huffman has said "people who use it are idiots".
