As mentioned above, it’s natural for hemp-derived CBD oil to contain traces of THC; and these traces may accumulate in your body over time. Taking doses of more than 1000 mg of full-spectrum CBD daily can make you test false positive for THC.

CBD alone won’t make you fail a drug test. These tests aren’t designed to look for CBD. Instead, they check for THC-COOH, which is the byproduct of THC. When your drug test score shows 50 ng/mL of THC in the tested sample, it will show a positive result. This may happen when a person takes very high doses of full-spectrum CBD oil daily (upwards of 1000 mg) for long periods of time. Full-spectrum CBD oil comes with up to 0.3% THC, but when you take regular doses, the risk of failing a drug test is 1-to-500.

Okay, we know we’re repeating ourselves like history, but workplace hair follicle tests are generally designed to check for THC, not CBD. Hair follicle tests are designed to detect that old standby THC-COOH. But then again, consuming high doses of full-spectrum CBD oil may have you end up with detectable traces of THC’s metabolite in your hair follicle. Any CBD product with trace amounts of THC could leave its byproducts in hair, where they can stick around for a while. Hair follicles can ‘store’ a month-long record of THC use, depending on the length of the hair.

How Much CBD Oil Will Make You Fail a Drug Test?

CBD doesn’t show up on a drug test because employers aren’t concerned about testing for it. What they are interested in is THC. It’s the THC — or more precisely, its excess amounts in CBD oil — that can make you fail a drug test.

These numbers tell us that there is about a 1-in-500 chance of failing a drug test after taking normal daily doses of hemp-derived CBD oil. Still, users should always check if their product was third-party tested, as many CBD oil labels out there are inaccurate.

Can CBD Turn into THC in the Body?

Last but not least, there’s a risk of buying a mislabelled product. The CBD market is still unregulated by the FDA, which creates room for fly-by-night vendors who aren’t afraid of churning out low-quality, contaminated products — selling them as a miracle cure. According to one study, almost 70% of the CBD products sold online are mislabelled, causing potential danger to consumers. This is why we always underline the importance of third-party lab testing (3).

Although CBD alone won’t make you fail one – drug tests don’t look for THC — a CBD oil product is capable of it.

Drug tests don’t screen for CBD, but that doesn’t mean you’re in the clear.

How cannabis drug tests work

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 oil under the tongue — it’s absorbed along with other fats and can be stored in your body’s fatty tissue.

Cannabis products in which cannabidiol (CBD) is the primary chemical constituent (CBD-dominant) are increasingly popular and widely available. The impact of CBD exposure on urine drug testing has not been well studied. This study characterized the urinary pharmacokinetic profile of 100-mg oral and vaporized CBD, vaporized CBD-dominant cannabis (100-mg CBD; 3.7-mg ∆9-THC) and placebo in healthy adults (n = 6) using a within-subjects crossover design. Urine specimens were collected before and for 5 days after drug administration. Immunoassay (IA) screening (cutoffs of 20, 50 and 100 ng/mL) and LC-MS-MS confirmatory tests (cutoff of 15 ng/mL) for 11-nor-9-carboxy-∆9-tetrahydrocannabinol (∆9-THCCOOH) were performed; urine was also analyzed for CBD and other cannabinoids. Urinary concentrations of CBD were higher after oral (mean Cmax: 776 ng/mL) versus vaporized CBD (mean Cmax: 261 ng/mL). CBD concentrations peaked 5 h after oral CBD ingestion and within 1 h after inhalation of vaporized CBD. After pure CBD administration, only 1 out of 218 urine specimens screened positive for ∆9-THCCOOH (20-ng/mL IA cutoff) and no specimens exceeded the 15-ng/mL confirmatory cutoff. After inhalation of CBD-dominant cannabis vapor, nine samples screened positive at the 20-ng/mL IA cutoff, and two of those samples screened positive at the 50-ng/mL IA cutoff. Four samples that screened positive (two at 20 ng/mL and two at 50 ng/mL) confirmed positive with concentrations of ∆9-THCCOOH exceeding 15 ng/mL. These data indicate that acute dosing of pure CBD will not result in a positive urine drug test using current federal workplace drug testing guidelines (50-ng/mL IA cutoff with 15-ng/mL confirmatory cutoff). However, CBD products that also contain ∆9-THC may produce positive urine results for ∆9-THCCOOH. Accurate labeling and regulation of ∆9-THC content in CBD/hemp products are needed to prevent unexpected positive drug tests and unintended drug effects.
