How long is LSD detectable in your body?

How long a drug is detectable in your blood or urine depends on a number of factors. For example, how often and how much you use and your personal metabolism (the speed at which a substance is broken down by mostly your liver). Drugs are longer detectable in your urine than in your blood. LSD is detectable in the urine up to 48 hours after ingestion. In general, LSD is not tested for in a urine test.
