Iowa bans sale of K2

The Iowa Board of Pharmacy has voted ban the sale of K2, a synthetic version of marijuana. The ban takes effect Wednesday. K2 is sold as incense and can cause a marijuana-like high for some users. Experts say it can also cause anxiety, hallucination and seizures. The substance was implicated in the suicide of an Indianola teenager in June. State officials had discussed asking legislators to ban K2 in January. The pharmacy board decided instead Tuesday to act on its own. It passed an emergency measure reclassifying the substance as a Schedule I drug that cannot be legally sold or possessed.
