FR-- They're a waste of time for general employment, too. The false positive rate is usually higher than the rate for a true positive. Ehrenreich had some industry numbers that showed it cost about $7000 per person accurately positive since you're spending money testing so many people that are pissing clean; for a piss test, you can be a stone alcoholic, use MDMA, GHB (and other club drugs), hallucinogens, meth/crank/ice/speed, opiates, barbituates, etc. and they will clear your body within 72 hours. Smoke a joint and you'll test positive for weeks to a month because THC's fat soluble. If you're really worried about public safety due to drug use, have your employees do a short reaction time test. Shit, I'd fail that if I had a migraine, which is why I try not to drive with one.
