Transmetron has facilities that can provide testing for the JWH-018 and JWH-073 synthetic cannabinoids which are the ingredients that cause the high created by K2.
K2 and Spice are two compounds typically found in synthetic cannabinoids, also known as the JWH-018 and JWH-073 metabolites, and are generally referred to as "herbal incense" or "legal highs." Some drug users, especially those undergoing drug probation or rehabilitation, have admitted to resorting to K2 or Spice use as an alternative to marijuana.
The compounds, currently not classified as controlled substances, are secretly sprayed on natural herbal blends, which are then legally sold as seemingly innocent products like vanilla or baybean. Synthetic cannabinoid products are manufactured in Asia and then sold in local markets throughout the U.S.—including gas stations, liquor stores, convenience stores, smoke shops, or on the Internet—under the brand names “K2,” “Spice,” “Sence,” “Yucatan Fire,” “Skunk,” or “Genie.”
When smoked or ingested, JWH-018 and JWH-073 can produce marijuana-like effects by acting as primary receptor agonists. The compounds have been found in as many as 25 different herbal blends, and even though they closely resemble marijuana, they still remain undetectable under standardized drug testing.
