how long lsd last in urine
How Long Does LSD (Acid) Stay in Your System? 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.
