A drug test for marijuana is the analysis of a biological specimen from your body, using urine, blood, hair, sweat or saliva samples to determine how much of the drug is in your system. Testing for marijuana checks for levels of the active ingredient THC, or more commonly for its metabolite THC-COOH.
Drug Test Detection Times. Drug tests detect not only drugs but metabolites as well. Metabolites are the byproducts of a substance after it has run through your system. To determine whether you will pass or not, it is important to know how much of the illicit metabolites are in your urine, as well as the test âcut off,â or Level of Detection (LOD). Usually marijuana tests will have a cutoff of 50ng/mL, but it can be as low as 25ng/mL. Home testing can tell you whether your level at the time of the test is above or below the 50ng/mL level, but it will not tell you the exact level of THC metabolites in your system.
