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.
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
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 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.
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.
Some sources report that in rare cases, false positive test results have come from CBD oil that breaks down into very small amounts of THC in the stomach. Other studies, however, have refuted this.
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).
When a drug test is performed, the active chemical in marijuana that gets detected in a positive screening is THC. However, most people are under the impression that CBD oil is THC-free.
How to Avoid a Positive CBD Drug Test
In fact, one study discovered that almost 70 percent of the CBD products sold online were not labeled properly, “causing potential serious harm to its consumers.” The reason for this widespread mislabeling is that CBD products are not strictly regulated by the FDA.
What are the odds that CBD oil users will test positive when subjected to illicit drug screenings, and what can be done to prevent it?
Drug tests look for tetrahydrocannabinol (THC), which is the element in marijuana that causes a high. CBD oils can have trace amounts of THC even if they're labeled “THC-free.” The FDA does not regulate these products, and mislabeling is common.
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.
So you’re in the clear, right? Not quite. There are two ways you could hit that 50 ng/mL mark.
You nailed your cover letter and rocked the interview. All that’s standing between you and an awesome new job is a mandatory drug screening. Will that CBD oil you’ve been taking for pain relief cause you to fail the test?
Drug tests don’t screen for CBD, but that doesn’t mean you’re in the clear.
How cannabis drug tests work
To hit 50 ng/mL of THC, you’d probably have to consume upwards of 2,000 mg of CBD products that contain 0.3% or less of THC, which is much higher than the average person is likely to take. Even in clinical trials and research studies, people are usually only administered 100-800mg/day.

First, THC is fat-soluble, so when you ingest it — especially via edibles or a drop of oil under the tongue — it’s absorbed along with other fats and can be stored in your body’s fatty tissue.
Different types of drug tests have different detection thresholds, but the type you’re most likely to encounter is the “pee test.” To pass a urine drug test, the amount of THC in your body must be below 50 ng/mL. That’s the cutoff recommended federally by the National Institutes of Health and clinically by the Substance Abuse and Mental Health Services Administration, which helps set industry standards for lab certifications.
