will cbd oil cause me to fail a drug test

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.

Factors in CBD Oil Showing on Drug Screen

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 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.

CBD is one of many active chemical compounds in the cannabis plant. One reason it’s gaining momentum in popularity is because it is said to lack the component of the plant that causes a person to get high, which is called THC (tetrahydrocannabinol).  

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.

Study of CBD Oil

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.

Some sources report that in rare cases, false positive test results have come from CBD oil that breaks down into very small amounts of THC in the stomach. Other studies, however, have refuted this.  

There are several common reasons a person fails a CBD drug test.

CBD is promoted for easing anxiety, insomnia and chronic pain, among other ailments. The jury is still out on those uses, but there is some science behind the compound. Last year, the U.S. Food and Drug Administration (FDA) approved a drug containing pure CBD — called Epidiolex — for treating certain rare, severe seizures.

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

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

It all points to the importance of taking “cross-reactivity” into account when a drug screening test comes back positive, Kroner 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.
