How long can LSD be detected in the body?
This varies by the test being used, the detection limit placed on the test, the point of collection and type of the sample fluid, the amount of LSD that was taken, and the individual in question. Assuming the testers are using an RIA screening test with the cutoff set at 0.1 ng/ml and assuming that the user has recently emptied their bladder, then the detection limit for one hit (100 ug) is normally around 30 hours. Each doubling of the initial amount will add about 5 hours. Thus taking 8 hits will leave a user vulnerable for approximately 2 days.
