"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."
