When I first read this story I was thinking thinking, why would a store owner be forced to remove a spice from his shelves? I guess I'm too out of touch, and since I don't have any children, I wouldn't know about these things.
Apparently "Spice" is a fake marijuana. Wikipedia gives a definition of "Spice" as being synthetic marijuana that does not cause one to test positive for marijuana. Makes me wonder if chemicals are involved in this? Marijuana is a plant but how does "Spice" become fake marijuana?
