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.
If you prefer CBD oil, tincture, gummies, or other ingestible forms, go with a product made from CBD isolate or crystalline CBD. These use 99% pure CBD so you don’t have to worry about THC or anything else being in there.
CBD is a non-intoxicating cannabinoid found in cannabis plants, and some say it provides the benefit of relaxation without THC’s high.
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.)
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.
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.
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.
What should you do if you use any of these products and have a drug test coming up?
Given that context, it’s important to understand how the compounds interact with drug screening tests, said Grace Kroner, lead researcher on the new study.
Researchers found that CBD, or cannabidiol, did not react with either of two commercially available tests used to screen for marijuana use. However, another cannabis compound — cannabinol (CBN) — did.
CBN, meanwhile, is far less famous than its cousin, but it is used in products marketed as sleep aids.
CBD is promoted for easing anxiety, insomnia and chronic pain, among other ailments. The jury is still out on those uses, but there is some science behind the compound. Last year, the U.S. Food and Drug Administration (FDA) approved a drug containing pure CBD — called Epidiolex — for treating certain rare, severe seizures.
She and her colleagues at the University of Utah Health Sciences Center in Salt Lake City spiked three batches of urine samples with CBD, CBN and two other cannabis compounds — cannabichromene and cannabigerol.
A 2017 study found that about seven out of 10 CBD products did not contain the amount of cannabidiol stated on the label. And about one in five contained 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.
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
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 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:
