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.
Occasional marijuana use can appear in your urine for up to 10 days. If you smoke more often, you might leave traces for up to 30 or even 100 days. Cocaine passes through your urine quicker, up to 5 days for infrequent use and up to 10 days if you use more heavily. Either way, youâll need more than water to pass your drug test.
