What is MOP on a Drug Test
"MOP" in the context of a drug test refers to the metabolite "3-O-methylmorphine," a derivative of morphine. Morphine is often tested for in drug screenings due to its association with opioids. MOP is one of the markers used to detect morphine and its presence in urine samples. Drug tests aim to identify substances or their metabolites to determine if an individual has consumed drugs. Detection of MOP suggests recent morphine or heroin use.
