will cbd oil show on a drug test

Cannabidiol (CBD) has recently surged into the therapeutic spotlight for its perceived anti-inflammatory, anti-anxiety, pain-relieving, and seizure-suppressing properties. CBD products can be found in health and wellness aisles across the world — perhaps even at your local Walgreens or CVS — in many forms, some of which include CBD oil, tinctures, edibles, elixirs, and more.

Some concerned consumers may wonder if a CBD-specific test exists. Technically, since CBD is a chemical that your body metabolizes, a specific test could be developed to detect it. But the average drug test is not designed to identify usage of CBD or CBD oil specifically.

How to consume CBD without THC

Although hemp-derived CBD products are available in states where recreational cannabis isn’t legal, some people might worry whether CBD will show up on a drug test. It’s a valid concern considering that even CBD products derived from hemp are legally permitted to contain traces of THC, 0.3% or less to be exact. And even in states where it is legal to buy THC-heavy cannabis from a retail store, some employers still screen employees for cannabis use. This may leave some consumers wondering whether there’s a small amount of THC in their CBD — and whether that will show up on 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.

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.)

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.

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:

A secondhand exposure scenario that is more likely is a positive hair test for marijuana that results from directly contacting marijuana paraphernalia or from someone who has THC on their hands. For example, if somebody who was in contact with marijuana then turned around and touched your hair, you might end up with a false positive drug test, if it was a hair test.

But, CBD products can cause problems when it comes to a drug test. It can be tricky. That is, drug tests screening for THC that have CBD in them might come back positive, since a lot of CBD products do contain trace amounts of THC in them that tests will detect in your bloodstream.

Your best bet is to do your research, and take the utmost caution when buying a CBD product to ensure it’s pure, particularly if you must undergo a drug test.

Reasons for Failing a CBD Drug Test

In rare cases, a false positive test could occur from CBD oil breaking down in small amounts of THC in your stomach. It’s theoretically possible for you to have traces of THC metabolites in your stomach acid when you ingest “less-purified CBD productions.”

Inadvertent marijuana exposure (through secondhand smoke) isn’t likely to be enough for you to end up with a positive result on your drug test. But, if you’re in a room with heavy marijuana smokers for a few hours, it could cause you to inhale enough THC smoke that could result in a positive drug test.

One study suggests as long as the CBD is pure, it won’t show up on a drug test. Researchers of the study found CBD didn’t react with a couple commercially available tests for screening marijuana use.
