No, it will not show up in a drug test... Cocaine (cocaine & benzoylecgonine), Marijuana, Opiates (Codeine, Morphine & 6-monacteyl morphine), Amphetamine (Meth/amphetamine & Ecstasy) and Phencyclidine (PCP, angel dust). Are mostly what they test for. Even if they did test for ambien it dosn't take but 1-3 days to clear up out of your system without any help from water, etc
