Cannabidiol (CBD) is a non-intoxicating compound found in marijuana. But can it show up in a drug test for the psychoactive cannabinoid tetrahydrocannabinol (THC)?

To find out if CBD would show on a urine drug test, I consulted employment drug testing expert Barry Sample, who is the director of science and technology for Quest Diagnostics, one of the larger diagnostic testing firms in the U.S.

“If the product contains only CBD and has had the THC removed, then an individual being tested would not be expected to test positive for marijuana or marijuana metabolite,” Sample says via email.

For good measure, I contacted marijuana health and science researcher, Paul Armentano. Armentano says via email: “Not unless those products also contain quantities of THC. Drug tests screen for either THC or the carboxy-THC metabolite, not for CBD.”

Both experts agree: As long as there is no THC in the CBD products, then a urine test would not yield a positive result for THC metabolites.
