Possibility of Positive THC Test Through Exposure to Hemp Products
"Results of the hemp products tested indicate the amount of THC present in commercially available products is significantly less in products available today than those reported in the past (15-22). As a result, the probability that these products will produce urine THC metabolite levels greater than the DoD and HHS confirmation cutoff of 15 ng/mL is significantly reduced and should not be considered as a realistic cause for a positive urine analysis result."
