LAS VEGAS -- In January 2010, Lt. Gen. Stanley T. Kresge, former commander of the U.S. Air Force Warfare Center, issued a general order banning the use of spice, salvia divinorum, and salvinorin in any form by members of the Nellis and Creech Air Force Base communities. The order prohibits the purchase, distribution or possession and use of any spice product. Spice was legal to sell in the civilian community until Nov. 24, when the Drug Enforcement Administration used its emergency powers to ban spice and other products that mimic the effects of marijuana. Spice is made in many different varieties, all of which have a disclaimer identifying it as incense not for human consumption. (U.S. Air Force photo illustration by Tech. Sgt. Michael R. Holzworth)
