Missouri has become the latest state to ban products containing synthetic cannabinoids, with Gov. Jay Nixon signing into law this week a bill making them and products containing them controlled substances in the state. The law goes into effect August 28.
K2, Spice and similar products began appearing in Europe in 2006 and started showing up in this country last year. They are now banned in most European countries, but not in the US, although the DEA has labeled JWH-018 a "drug of concern."
An increasing number of states are not waiting for the feds to act. This year, K2 was criminalized in Alabama (the same law also outlawed salvia divinorum), Arkansas, Georgia, Kansas, Kentucky, Louisiana (effective August 15), North Dakota, and Tennessee. Similar legislation has been proposed in several more states, including Florida, Illinois, and New York.
