Can CBD make you fail a drug test?

While drug tests don’t screen for CBD, there are some things you should be aware of.

When it comes to marijuana, drug tests typically only screen for THC — the psychoactive compound in cannabis that gets you “high”. 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 are most likely to encounter is the “urine test.” To pass a urine drug test, the amount of THC in your body must be below 50 ng/mL. That is 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 would probably have to consume upwards of 2,000 mg of CBD products that contain 0.3% or less of THC. This 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 necessarily. There are two ways you could hit that 50 ng/mL mark.

Why CBD could cause you to fail a drug test.

First, THC is fat-soluble, so when you ingest it — especially via edibles or tinctures (a drop of oil under the tongue) — it’s absorbed along with other fats that 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 is possible for THC to accumulate in your body. This could, in turn, trigger a positive drug test. Research has found that THC can be detectable in your system for up to 30 days, but it is usually only present in heavy cannabis users for the first week.

TL;DR

While it is possible for heavy CBD users to fail a drug test, the conditions are unlikely to occur if the product is well made and used as instructed.
