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 oilyou’ve been taking for pain relief cause you to fail the test?

How cannabis drug tests work

When it comes to marijuana, drug tests typically only screen for THC — the compound in cannabis that gets you “high” — or one of the compounds created when your body metabolizes it. And by law CBD products can only contain up to 0.3% THC.

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.

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.

So you’re in the clear, right? Not quite. There are two ways you could hit that 50 ng/mL mark.

Why CBD might cause you to fail a drug test

First, THC is fat-soluble, so when you ingest it — especially via edibles or a drop of oilunder the tongue — it’s absorbed along with other fats and can be stored in your body’s fatty tissue.

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.

Second, there’s a good chance that the CBD product you’re using contains more than the .3% THC legally allowed. In fact, when Penn Medicine researchers bought CBD products online and then analyzed their ingredients, they found that about one in five contained up to 6.4 mg/ML of THC — high enough to cause impairment.

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 marijuanacommonly known as Spice and K2.

If you have to take a drug test and use CBD

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.
