A relatively new type of stimulant drug is causing alarm, and people who take them sometimes turn violent and psychotic. The stimulants, "bath salts," are sold legally in many states and can be purchased in some convenience stores because of a label that says "not for human consumption.” They come in powder or crystal form like traditional bath salts, but people take them as recreational drugs, snorting, injecting, or smoking them. The drug, which has turned up in the past year, has already been banned in at least 28 states, mostly in the South and the Midwest.
