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.
Because of its short half-life, LSD can be detected in the urine for up to eight hours. This detection window is shorter than that of many other drugs. For example, marijuana can be detected in the urine of heavy cannabis users for up to two months after last use. Upon consumption, LSD breaks down into 2-oxo-3-hydroxy-LSD, a major metabolite of the drug that can be found in urine.
