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:
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.
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
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.
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 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.
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.
When consuming pure CBD, there is evidence you’ll be missing out on some health goodies conveyed by the entourage effect if you chose a full- or broad-spectrum CBD product instead. But it’s the only way to be certain there’s no THC in your CBD, and the only way to buy CBD in states with highly restrictive laws.
Upon inhalation, active THC can be found in the bloodstream within a matter of seconds and can be detected in plasma for several hours, depending on the frequency of use and dosage. According to a 2004 review published in the journal Therapeutic Drug Monitoring, the plasma concentration of THC peaks just three to eight minutes after inhalation and then decreases quickly with a half-life of about 30 minutes. The study claims that THC is detectable in blood for about five hours, but the THC metabolite THC-COOH has a detection time of up to 25 days.
How to read a CBD label
For example, if someone smokes a joint and exhales near someone who doesn’t consume cannabis, THC can be transferred to the non-smoker’s head or body hair. The same study found that, after giving participants 50 milligrams of THCA every day for one month, no THC was found in the hair specimen samples, but THC-COOH was still detected. As for the detection period, the hair follicle drug test timeline is much broader than with urine and blood tests, sometimes detecting the presence of THC up to 90 days after use.
To obtain a CBD drug test, an entity would have to pay a testing company to develop a CBD test and to change their testing regimen to include it. When you consider that this non-intoxicating compound won’t get you high or impair your ability at work, there’s really no need for a CBD drug test.
Whichever method, or methods, you choose, be sure to buy from a reputable source and check the label carefully. Since the Food and Drug Administration (FDA) hasn’t established guidelines for CBD products, it’s buyer beware. Avoid any product making health claims like that it cures or treats anything specific. Most reputable CBD producers typically include the following information on their product labels:
