Abstract
Human urine samples obtained before and after active and passive exposure to marijuana were analyzed by Immune kits (Roche, Amerehsm, and Syva) and gas chromatography/mass spectrometry (GC/MS). Seven of eight subjects were positive for the entire five-day test period with one immune kit. The latter correlated with GC/MS in 98% of the samples. Passive inhalation experiments under conditions likely to reflect realistic exposure resulted consistently in less than 10 ng/mL of csnnablnoids. The 10-100-ng/mL cannsblnoid concentration range essential for detection of occasional and moderate marijuana users is thus unaffected by realistic passive Inhalation.This publication has 3 references indexed in Scilit:
