K2 Spice Drug Test – Synthetic Marijuana Urine Drug Testing

What are synthetic cannabinoids?
Synthetic Cannabinoids, a class of designer drugs, are available in head shops, tobacco stores, and over the Internet under a variety of names, such as, “K2”, “Spice”, “Tucatan Fire”, “Skunk”, “Moon Rocks”, “Black Mamba”, and “Bombay Blue”. They are often labeled “not for human consumption” and common routes of administration include inhalation and oral ingestion.1

Regular users of Synthetic Cannabinoids may experience withdrawal and addiction symptoms.2 Tolerance to these agents may develop rapidly, which might be associated with dependence.3 The compounds are stored in the body for a long period of time and long-term effects on humans are not known.1

In 2010, the American Association of Poison Control Centers received 2,906 calls related to synthetic cannabinoids. In 2011, the number of calls received increased to 6,959.4 On July 9, 2012, President Obama signed into law the Synthetic Drug Abuse Prevention Act banning synthetic compounds commonly found in synthetic marijuana, by placing them under Schedule I of the Controlled Substance Act.   5
