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.
Factors in CBD Oil Showing on Drug Screen
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.
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.
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:
“2 of 6 participants tested positive for cannabis after they inhaled CBD-dominant cannabis vapor.”
During a recent conversation, postdoctoral fellow Tory Spindle, Ph.D., a researcher in the Behavioral Pharmacology Research Unit at the Johns Hopkins Bayview Medical Center, explained how we drug-test for cannabis.
And this is what Johns Hopkins Medicine researchers set out to do in recent months, publishing their findings at the Journal of Analytical Toxicology this week.

In his and his colleagues’ opinion, these results have important implications for consumers of CBD products.
After dosing, they provided urine samples to determine whether they would test positive for cannabis using common drug testing standards.
And, while some studies have suggested drug testing at work is a thing of the past, this is not the case for all jobs. Some jobs, as well as criminal justice and addiction treatment proceedings, among others, still require drug testing.
With legal cannabis and hemp hitting the mainstream hard, and expanding rapidly across the U.S. and the rest of the world, the availability of products containing CBD in considerable proportions is exploding.
While some CBD oils claim to be isolates, they may be full spectrum oils and actually contain more cannabinoids (such as THC) than they claim.
However, the distinction between full spectrum oils and isolates make all the difference if you are being tested for drug use.
1. Using Product With THC
A more likely secondhand exposure scenario is a positive marijuana hair test, resulting from direct contact with marijuana paraphernalia or from another person having THC on their hands.
In fact, one study discovered that almost 70 percent of the CBD products sold online were not labeled properly, “causing potential serious harm to its consumers.” The reason for this widespread mislabeling is that CBD products are not strictly regulated by the FDA.
Cannabis is the umbrella term describing hemp and marijuana plants—two different varieties of the cannabis genus. Both marijuana and hemp can be described as cannabis plants; however, it is important to note that they are still two separate plants.
