Novel CBD™ THC Free Hemp-Derived CBD products contain 0.0% THC, so they are safe for those who must take a test for the positive presence of THC. As with all hemp products, using our Full Spectrum products creates the chance that a positive test for THC could be triggered despite there only being trace amounts present in the oil. We recommend you consult with your employer or doctor before taking Full Spectrum products if a positive test for THC is a concern.
