A more likely secondhand exposure scenario is a positive marijuana hair test, resulting from direct contact with marijuana paraphernalia or from another person having THC on their hands.
If you take CBD oil, there are measures you can take to try to prevent failing a drug test.
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).
5. CBD Oil Breaks Down in The Digestive System
Most CBD products are made from hemp, not marijuana.
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.
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 plants; however, it is important to note that they are still two separate plants.
The primary difference between hemp and marijuana is that hemp is nearly void of THC. In fact, a cannabis strain must contain less than .3 percent THC to be classified as hemp. This is the reason hemp can be legally sold as various products.
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.)
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.
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.
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:
Topical CBD products like ointments, lotions, or balms don’t enter the bloodstream in a way that would be picked up by a drug test. Even if it contains the federally legal amount of 0.3% THC, topicals are still safe as far as drug testing is concerned.
What drug tests look for
CBD is a non-intoxicating cannabinoid found in cannabis plants, and some say it provides the benefit of relaxation without THC’s high.
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.
THC and its metabolites can also be detected in the saliva of occasional and chronic users. A 2014 study published in the journal Drug Testing and Analysis looked at cannabinoids in oral fluid and found that THC metabolites were detectable in the saliva of occasional users for one to three days and chronic users for up to 29 days.
