CBD oil is usually marketed as THC-free, but that's not always the case. Full-spectrum CBD oils contain other cannabinoids, which may include THC. Isolate products may be contaminated with THC, as well.
As it turns out, depending on the source of the cannabis that is used to produce the CBD oil, some products do contain traces of THC. This includes low-quality isolates and many full-spectrum tinctures. A full spectrum oil contains other active plant compounds in addition to the CBD.
Drug tests look for tetrahydrocannabinol (THC), which is the element in marijuana that causes a high. CBD oils can have trace amounts of THC even if they're labeled “THC-free.” The FDA does not regulate these products, and mislabeling is common.
Use the utmost caution and do your research when purchasing a quality CBD oil product to ensure its purity, especially if you need to undergo a drug screening.
There are several common reasons a person fails a CBD drug test.
These compounds were derived from a full-spectrum product rather than a CBD isolate product alone. This is one reason that full-spectrum products (those containing THC) are popular.
There are several techniques for extracting CBD oil from the cannabis plant. The extraction method determines whether the CBD oil is an "isolate" or a “full-spectrum oil.”
Study of CBD Oil
The most common reason for a failed CBD drug test is that a person is using a CBD oil product that contains THC. This may be a full-spectrum product. Sometimes, though, it could be a low-quality isolate product that contains a small amount of THC.
For instance, say that someone who had direct contact with marijuana then touched your hair. You could feasibly receive a false positive on a drug screening that tests your hair.
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.
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.)
Taking CBD If You Undergo Drug Tests
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.
