Use the utmost caution and do your research when purchasing a quality CBD oil product to ensure its purity, especially if you need to undergo a drug screening.
For instance, say that someone who had direct contact with marijuana then touched your hair. You could feasibly receive a false positive on a drug screening that tests your hair.
A study conducted at the internationally known Lautenberg Center For Immunology and Cancer found that CBD was more effective at treating inflammation and pain when used with other cannabis plant compounds.
You have to be proactive to avoid failing a drug test if you're taking CBD oil. Most important: Ensure that you're using a pure product made by a reputable company.
A Word From Verywell
These compounds were derived from a full-spectrum product rather than a CBD isolate product alone. This is one reason that full-spectrum products (those containing THC) are popular.
There are several common reasons a person fails a CBD drug test.
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, but they are two different plants.
CBD Oil Breakdown in the Digestive System
Although most manufacturers claim their products do not contain THC, this is not always the case.
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 finding.
Depending on how much CBD (and thus THC), you consume, how often you consume it, your body weight and your diet, it’s possible for THC to accumulate in your body in as little as four to six days and trigger a positive drug test. Research has found that THC can be detectable in your system for up to 30 days, but it’s usually only present in heavy cannabis users after the first week.
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?
While the information here suggests CBD won’t make anyone fail a drug test, there’s no way to guarantee that. The only way to ensure you will pass a drug test is to abstain from using any sort of CBD product.

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.
And in 2018, the CDC released a report that found that more than 50 people in Utah were poisoned by CBD products that actually contained synthetic marijuana commonly known as Spice and K2.
How cannabis drug tests work
Drug tests don’t screen for CBD, but that doesn’t mean you’re in the clear.
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.
