What drugs will test positive for morphine?

Anything containing opiates or opioids will result in a positive on a drug test. This includes almost all prescription painkillers (vicodin, codeine, percocet, hydrocodone, oxycontin, etc.), heroin, opium, and of course...morphine. Morphine can be detected in your urine for up to four days after consumption, while other opiates may dissipate in only one or two days.
