The feature article about CBD supplement use in the February Talk Greenville magazine described the growing use of CBD products. As an occupational medicine physician, I see a different side of CBD related to workplace drug testing.
It’s important to understand that CBD supplements almost universally are made from hemp oil, which contains small but measurable amounts of THC (tetrahydrocannabinol), the psychoactive part of marijuana/cannabis. This THC is detectable in users at the tiny, part-per-billion level employed by lab testing in DOT and Drug-Free Workplace Testing programs, and there is no way to tell the difference between the sources of THC.
So if THC is in your body from CBD or by using marijuana and you’re tested, the lab likely will find it. Consequently, CBD users are at high risk for having a test result report of „positive for marijuana.” I see positive drug screen cases like this almost weekly in my drug test medical reviews.
