"Spice" refers to a wide variety of herbal mixtures that produce experiences similar to marijuana (cannabis) and that are marketed as "safe," legal alternatives to that drug. Sold under many names, including K2, fake weed, Yucatan Fire, Skunk, Moon Rocks, and others — and labeled "not for human consumption" — these products contain dried, shredded plant material and chemical additives that are responsible for their psychoactive (mind-altering) effects.
