I Use CBD Oil. Will I Flag Positive Currently-Available Hair Testing for Marijuana?

With cannabis gaining broader acceptance in Canada and the United States, more and more people have begun using CBD oil recreationally and as a medical supplement. Some folks ingest drops of CBD oil under their tongue, or suck on CBD-infused candies, or even lather down with a CBD-laden soap in the shower. This raises an important question for those who are expected to submit to pre-employment drug tests: will CBD oil cause you to test positive on the available hair testing for marijuana?

Cannabidiol or CBD is one of two compounds prominent in the cannabis plant, with the other being THC. Importantly, CBD is the non-psychoactive of the two, producing an analgesic and relaxation effect more than anything else. In addition to being used to ease anxiety and insomnia, the FDA recently approved its use for certain forms of epilepsy.

Most common drug tests are looking for cannabis use. However, they usually aren’t looking for CBD.

In short, if you’ve been taking CBD oil, but not ingesting other forms of cannabis, you’ll probably not screen as positive on the currently available hair testing for marijuana.

But it’s not a sure thing.

The typical drug test is designed to screen for THC, which is chemically distinct from CBD. If you’ve been taking pure CBD, there shouldn’t be an THC in your body. Therefore, no positive.

Trouble is, many hemp-based CBD products on the market contain trace amounts of THC. That’s because some researcher believe that small amounts of THC are necessary to enhance or ‘trigger’ CBD’s desirable effects.

That creates the possibility that there is THC in your body and it can come up on your pre-employment drug test. But it’s a pretty small possibility. Trace amounts of THC (0.3% or lower) shouldn’t accumulate in sufficient amounts to come up.

But it has happened. One woman in Atlanta, for instance, failed a THC drug test despite never having used cannabis in her life. The culprit was the CBD oil she’d been taking for anxiety, which had apparently contained enough THC to build up in her body.

Part of the reason why this is a concern is that CBD isn’t tightly regulated yet. Although CBD products generally don’t contain more than 0.30% THC, it isn’t a sure thing; at least not as sure as the ingredients in most supplements you’d purchase at the pharmacy.
