The results were highly instructive: At the 100 ng/mL threshold zero non-smoker positives At the 75 ng/mL threshold zero non-smoker positives At the 50 ng/mL threshold (the DOT initial screening standard) only a single positive occurred, even in a sealed unventilated room with heavy smoke At a 20 ng/mL threshold multiple positives occurred Maximum THC metabolite concentrations for non-smokers by GC-MS ranged from 1.3 to 57.5 ng/mL under extreme unventilated conditions The key takeaway: for someone who does not smoke to fail a drug test due to secondhand smoke, they would need to be exposed to a high concentration of smoke in an unventilated space for a prolonged period
