Lysergic acid diethylamide (LSD) is a potent hallucinogen active at very low doses, making its detection and quantification difficult in body fluids and especially in hair. This review examines the challenges of LSD hair analysis, noting that only ten published cases provide data on LSD concentrations in hair. Interpretation of results is complicated by possible pubic hair contamination from urine and limited understanding of how LSD incorporates into and remains stable in head and pubic hair. The absence of LSD in head hair does not rule out consumption, and positive results cannot reliably distinguish single from repeated use. Even a positive pubic hair result does not formally prove repeated LSD use.
