Does CBD Show up on a Drug Test?

CBD craze sweeps the nation

Since the CBD craze sweeps the nation, some users might wonder if the cannabis extract can cause them to fail a drug test. Does CBD show up on a drug test? Preliminary research suggests that the answer is”no” — if the CBD remains pure.

Researchers discovered that CBD, or cannabidiol, did not react with both commercially available tests utilized to monitor for marijuana usage. Yet, another cannabis chemical — cannabinol (CBN) — did.


CBD and CBN are just two of many substances found in cannabis plants. They range from THC, the origin of the marijuana”high.” CBD is present in bud but more abundant in bark — cannabis plants which have very little THC. CBN, meanwhile, is still a THC derivative.

If you think CBD products are suddenly everywhere, you’re correct: There has been an explosion because this past year, when Congress raised a decades-old ban on growing hemp.

Licensed farmers are now able to grow the plant, as long as it contains less than 0.3percent THC. The outcome? CBD is turning up in everything from lotions and oils to java and cookies.

CBD is encouraged for easing anxiety, insomnia and chronic pain, as well as other ailments. The jury remains out on these applications, but there is some science behind the compound. Last year, the U.S. Food and Drug Administration (FDA) declared a medication comprising pure CBD — known as Epidiolex — for healing certain infrequent, acute seizures.

CBN, meanwhile, is far less famous than its cousin, however, it’s employed in products marketed as sleep aids.

Given this context, it’s important to realize how the chemicals interact with medication screening tests, explained Grace Kroner, lead researcher on the new analysis.

She and her colleagues in the University of Utah Health Sciences Center in Salt Lake City elicited three batches of urine samples with CBD, CBN and two other cannabis chemicals — cannabichromene and cannabigerol.

The researchers tested each batch with just two tests normally used for THC screening. CBN reacted with one, while the other three chemicals triggered no false-positives.

Why did only 1 test pick up CBN?

The tests are known immunoassays — which means they use insecticides to detect drugs. Kroner clarified that there are minor differences in the embryo which test manufacturers use — so it’s possible to find unique results.

While the findings may be a relief to some CBD users, there is a major caveat: The researchers used pure CBD. In the actual world, CBD products are largely unregulated and may contain different chemicals because of processing.

According to Robert Fitzgerald, a professor in the University of California, San Diego’s Center for Advanced Laboratory Medicine,”It would depend on the purity of the product.”

On the flip side, he noticed, immunoassays are only screening evaluations. They would be followed by”confirmatory testing” that does differentiate THC from other compounds. But you could still have a problem if your cannabis product was contaminated with THC, Fitzgerald explained.

Legally, Kroner mentioned, CBD products must only be generated from hemp plants with no greater than 0.3percent THC. But there is no way for consumers to understand for sure what’s in the products they buy.

A 2017 study found that approximately seven out of 10 CBD products didn’t contain the amount of cannabidiol stated on the label. And about one in five included THC.

A false-positive on a drug test could have consequences for people on the job, and in their own healthcare. For example, some health care organizations do not permit patients to begin opioid painkillers should they use marijuana.

Everything points to the value of accepting”cross-reactivity” into consideration when a drug screening test comes back positive,” Kroner explained.

“Confirmatory testing should be done before any clinical decisions are made,” she said.

What do you need to do if you utilize one of these products and also have a drug test coming up?

The simplest path would be to refrain for some time, according to Kroner. But she advised being up front on your CBD or even CBN use — or any supplement usage, for that matter — so your evaluation results can be interpreted in that light.

Kroner reported the findings Monday at the annual meeting of the American Association for Clinical Chemistry in Anaheim, Calif.. Studies demonstrated at meetings are generally considered preliminary until they are printed in a peer-reviewed journal.
