The most common reason for a failed CBD drug test is that a person is using a CBD oil product that contains THC. This may be a full-spectrum product. Sometimes, though, it could be a low-quality isolate product that contains a small amount of THC.
However, the distinction between full-spectrum oils and isolates makes all the difference if you are being tested for drug use.
Inadvertent exposure to marijuana (via secondhand smoke) is unlikely to be enough for a person to get a positive drug test result. But it is possible. Being in a room with heavy pot smokers for several hours may cause the inhalation of enough THC-containing smoke to result in a positive test result.
Mislabeling of Products
This article explains why a positive drug test can happen with CBD use, which types of CBD are most likely to trigger one, and what you can do to avoid it.
CBD oil extracted from hemp is not supposed to contain more than 0.3% THC. However, it’s not uncommon for sellers to mislabel their products as THC-free hemp when, in reality, it’s a low-quality oil extracted from marijuana. And marijuana does contain THC.
Cross-Contamination of THC
The active chemical in marijuana that gets detected in a positive drug test screening is THC. Most people are under the impression that CBD oil is THC-free, which is generally true. But not always.
CBD (cannabidiol) oil is a popular product for everything from pain control and anxiety to promoting sleep. However, with the rise of CBD use comes a concern about failing a drug test.
Even though the issues surrounding CBD testing in Texas sound troubling, they could still work in your favor. Similar to beating a DWI in Texas, you can use the nuances associated with lab testing to fight for your innocence if you are accused of driving under the influence of marijuana or are fighting against a probation violation due to a false positive result from CBD.
Before we can articulately explain why and how CBD can make you fail a drug test, let’s establish what CBD is and is not, as well as some of the definitions that are helpful to know if you’re worried about failing a drug test.
It’s also important to keep in mind that states have different regulations on marijuana as a whole. If you bring in CBD from another state, this could be problematic for you in Texas (even if it is considered legal in the state you purchased it in).
Current lab testing equipment does not differentiate between various levels of THC. This means that the equipment would yield a positive result whether there were trace amounts of THC or extremely high levels of THC.
Packing and labeling may not be entirely accurate
Even though HB 1325 outlines specific safeguards meant to avoid issues with production and packaging, this is still relatively new to Texas as a whole, and there are bound to be problems. Many studies show that CBD products often contain more THC than the packaging claims it contains (even if it claims to have 0% THC).
Some people use CBD to alleviate stress and reduce anxiety, while others use it to help with seizures or ease Cancer-related illnesses. Regardless of usage, CBD is considered a safe, non-psychoactive alternative to THC-heavy marijuana.
Although CBD is legal in Texas (as long as it contains a percentage less than 0.3 THC, more on that later), it can still result in a failed drug test. Let’s talk about why this happens and what you can do if you fail a drug test.
What is CBD: Pure Isolate vs. Broad/Full Spectrum
More specifically, researchers at John Hopkins have found “studies show that THC and its metabolites may accumulate with repeated use” which, over time, could result in a positive drug test.
Can CBD make you fail a drug test? It’s a question on a lot of people’s minds. Today, one-in-five adults aged 18-29 report using CBD regularly and for all kinds of reasons that have nothing to do with getting high.
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.

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.
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.
Why CBD might cause you to fail a drug test
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?
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.
Drug tests don’t screen for CBD, but that doesn’t mean you’re in the clear.
