If you are concerned that THC in your CBD oil or other CBD product may show up on a drug test, you may be able to reduce the chance of that occurring, though there is no guarantee. Some of the factors that may increase the likelihood of a failed drug test are:
Topical products that claim to contain CBD—like shampoos, cosmetics or creams—should not cause any reaction during a drug test because they do not enter the bloodstream. In the case of CBD oils, gummies, teas or transdermal patches, the situation is more complicated. In a test of 84 CBD products obtained online, 18 contained THC.
CBD has taken off as a natural remedy for a variety of ailments. CBD products like CBD oil can be made from either the hemp plant or the cannabis plant, which are closely related varieties of the same cannabis species, Cannabis sativa. CBD products contain a cannabinoid—a chemical—called cannabidiol, which does not make you high. The substance in marijuana that causes a buzz is a different cannabinoid, called THC, or tetrahydrocannabinol.
Factors in CBD Oil Showing on Drug Screen
CBD products can still be problematic, however, when it comes to drug testing. Though drug tests screen for THC, not CBD, many CBD products contain a trace amount of THC which will be detected in your bloodstream during a drug test.
THC can be detected in a urine test for up to 15 days, depending on how often and how much you use. It leaves the bloodstream in about five hours, but substances your body makes from THC (THC metabolites) can show up for as long as 7 days. CBD tends to stay in the bloodstream from 2 to 5 days, depending on dosage and frequency. If you have been using CBD for a while, it can stay in your body for up to 30 days or more.
The legality of CBD products can be confusing. CBD products made from certain cannabis plant varieties are legal only in states where marijuana is legal, due to the potential THC content. CBD products made from hemp variety plants are legal throughout the United States as long as they contain less than 0.3% of THC and do not make any medical claims. (A hemp plant is defined as Cannabis sativa that contains less than 0.3% THC.)
CBD will not show up in a drug test because drug tests are not screening for it. CBD products may well contain THC, however, so you can fail a drug test after taking CBD products. If you take CBD oil, you should plan accordingly if your work or activities require you to undergo drug testing.
Why did only one test pick up CBN? The tests are known immunoassays — which means they use antibodies to detect drugs. Kroner explained that there are slight differences in the antibodies that test manufacturers use — so it’s possible to get different results.
“Confirmatory testing should be done before any clinical decisions are made,” she said.
While the findings may be a relief to some CBD users, there is a big caveat: The researchers used pure CBD. In the real world, CBD products are largely unregulated and may contain other compounds due to processing.
What should you do if you use any of these products and have a drug test coming up?
She and her colleagues at the University of Utah Health Sciences Center in Salt Lake City spiked three batches of urine samples with CBD, CBN and two other cannabis compounds — cannabichromene and cannabigerol.
CBD can be sourced from marijuana or hemp. In many cases, the oil is extracted to be consumed as a liquid, made into pills, or mixed directly into food. Some people prefer to consume it through vaporizer pens, which — because you’re inhaling it — offers a more or less immediate reaction. (Important to note, though, is that vaporizer pens can carry their own downsides.)
It’s even being explored for its anti-cancer properties — although to be clear, this research is still very much in progress.
What is CBD?
As the medical marijuana industry continues to leave its footprint on the field of medicine, science — and the general population — are exploring new ways of experiencing it. Cannabidiol, or CBD, has stepped into the spotlight as a highly-regarded form of alternative medicine and has gained much traction in the medical marijuana industry. Furthermore, its list of benefits is no longer purely hypothetical. A growing body of research is finding that CBD could be highly beneficial to treat certain medical conditions. That doesn’t mean it’s workplace-friendly, though, which leads to the question: Can you fail a drug test due to CBD?
In fact, CBD can actually counteract the psychoactivity of THC. This makes it an appealing alternative for treating issues such as:
Others prefer to use it topically — for example, with CBD salves or creams that are applied directly to the body. This is a particularly interesting approach because since dermal absorption can’t produce psychoactive side effects, even if there is any THC present in the CBD, you still won’t feel high.
