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.”
A more likely secondhand exposure scenario is a positive marijuana hair test. This results from direct contact with marijuana paraphernalia or from another person having THC on their hands.
Using Product With THC
You have to be proactive to avoid failing a drug test if you're taking CBD oil. Most important: Ensure that you're using a pure product made by a reputable company.
CBD (cannabidiol) oil is a popular product for everything from pain control and anxiety to promoting sleep. However, with the rise of CBD use comes a concern about failing a drug test.
How to Avoid a Positive CBD Drug Test
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, but they are two different plants.
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:
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 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.
Taking CBD If You Undergo Drug Tests
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.
