PainRelief.com: What is the background for this study? What are the main findings?
Response: Cannabis and hemp products that contain CBD as the primary constituent have become widely available in the U.S. and are often used for various therapeutic purposes. However, there is presently little research to understand how such products could impact drug testing for cannabis which is commonly conducted in workplace, criminal justice, and other settings.
Drug testing for cannabis targets a common metabolite of THC called THCCOOH; THC is the primary psychoactive component of cannabis. Our results suggest that single use of a product that contains pure CBD would not produce a positive result on a standard urine drug test. However, we found that 2 of 6 participants tested positive for cannabis after they used a CBD-dominant strain of cannabis that contained a very low concentration of THC: only 0.39% THC.
