Question

Quizplus · Accepted Answer

6-monoacetylmorphine is a metabolite of heroin that is only present in urine for a short period of time after use, making it a specific and reliable marker for recent heroin use. Morphine and codeine are also metabolites of heroin, but they can also be present in urine as a result of other drug use or prescription medication, making them less specific indicators of heroin use. Morphine-6-glucuronide is a metabolite of morphine, not heroin.
