In theory, getting a false positive on a drug test from CBD oil should be relatively impossible from pure CBD oil containing less than .3 percent THC. However, because CBD oil is not very well regulated, there is no guarantee that a product contains pure CBD oil, or that its concentration is at a safe or effective level. It is best to use utmost caution and do your research when purchasing a quality CBD oil product to ensure its purity, especially if you need to undergo drug screenings.
What are the odds that CBD oil users will test positive when subjected to illicit drug screenings, and what can be done to prevent it?
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.
A Word From Verywell
The conclusion is that it’s still theoretically possible for traces of THC metabolites to be present in the stomach acid in the instance where “less-purified CBD productions” are ingested.
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.
Very small amounts of THC present in the material that CBD is extracted from can get into the CBD oil in high enough amounts to result in a positive drug test. This scenario may be more apt to occur when CBD oil is purchased from cannabis dispensaries in places where cannabis is legal, as opposed to an online retailer.
CBD (cannabidiol) oil is a popular product for everything from pain control to anxiety to promoting sleep. However, with the rise of CBD comes the concern about failing a drug test due to detection of CBD oil. News stories are emerging across the country involving famous sports players, employees of companies, and others who have gotten positive drug screening results for the presence of THC—the psychoactive component of marijuana —even though CBD oil is said to be THC-free.
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 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.
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
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 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.
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.
