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.
A 2005 review published by the National Drug Court Institute states that THC detection times rarely exceeded 30 days. According to a May 2017 review published in Mayo Clinic Proceedings, weed can be detected in urine for up to three days in occasional users, five to seven days in moderate users, 10 to 15 days in daily users, and more than 30 days for chronic users who consume multiple times a day.
There is no such a thing as a CBD drug test
If you’re vaping or dabbing your CBD, it’s the same advice as above — look for concentrates made with isolate or crystalline to avoid THC completely. (If you smoke or vape flower, you’ll be consuming whatever level of THC is present in the bud, which is at least 0.3% even for hemp plants.)
Recognized as the preferred method for cannabis drug testing, urine screenings are often used as a benchmark to detect for cannabis use. Most urine tests utilize a specific sensitivity for the cutoff concentration of THC-COOH. The most common cutoff concentration point is 50 nanograms per milliliter (ng/mL), as suggested by the Substance Abuse and Mental Health Services Administration (SAMHSA).
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:
In most cases, it’s highly unlikely that CBD will show up on a drug test. Usually employment drug tests look for the presence of THC or THC metabolites. Most employers abide by the guidelines set forth by the Substance Abuse and Mental Health Services (SAMHSA), which includes detection for THC but not CBD. Tests generally look for THC but how much and how long THC sticks around depends on what’s being tested.
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.)
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.
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.
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.
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 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.
The most common reason for a failed CBD drug test is that a person is using a CBD oil product that contains THC. Sometimes, this may be because a person purchases a low-quality product that does contain a small amount of THC—most manufacturers will claim their products do not contain THC, but this is not always the case.
CBD (cannabidiol) oil is a popular product for everything from pain control to anxiety to promoting sleep. However, with the rise of CBD comes the concern about failing a drug test due to detection of CBD oil. News stories are emerging across the country involving famous sports players, employees of companies, and others who have gotten positive drug screening results for the presence of THC—the psychoactive component of marijuana —even though CBD oil is said to be THC-free.
Very small amounts of THC present in the material that CBD is extracted from can get into the CBD oil in high enough amounts to result in a positive drug test. This scenario may be more apt to occur when CBD oil is purchased from cannabis dispensaries in places where cannabis is legal, as opposed to an online retailer.
3. Mislabeling of Products

However, the distinction between full spectrum oils and isolates make all the difference if you are being tested for drug use.
CBD oil extracted from hemp is not supposed to have any more than .3 percent of THC. However, it’s not uncommon for sellers to mislabel their products as THC-free hemp when in reality, it’s a low-quality oil extracted from marijuana, which does contain THC.
While some CBD oils claim to be isolates, they may be full spectrum oils and actually contain more cannabinoids (such as THC) than they claim.
