Does CBD Show on Drug Tests?

For digestible answers to all your biggest CBD questions, we have our CBD 101 guide, FAQ, and the Highline Blog. But some questions are more pressing than others, like whether or not CBD gets you high (spoiler alert: it doesn’t!). Another one of these more pressing questions is: does CBD show on drug tests?

So, does CBD show on drug tests? The short answer is that it shouldn’t, but depending on the quality of the CBD and potential cross-contamination with THC, it might. The question comes from a place of totally natural concern, so we’re here to break it down a little bit more!

These answers, by the way, are based on the most common type of drug tests that potential employers would use, which are typically for illicit substances like THC and narcotics. While legal in many states, THC is still unfortunately considered an illicit substance on the federal level. Since CBD is federally legal, it’s extremely unlikely you would ever have to take a drug test that would be screening for CBD. To reiterate the main point, CBD would not show up on a drug test unless there is enough THC present to trigger a positive.

Will CBD Show on Drug Tests?

According to a 2021 study in the academic journal Drug Testing and Analysis, pure CBD should not cause you to fail a drug test. Their findings suggest that CBD you consume, such as gummies and oils, is unlikely to elicit positive results on two particular types of tests that screen for THC.

In addition to the type of test, the purity of the CBD also plays a role. The type of test is clearly not in your control, but the type of CBD is! The three most common types of CBD used in today’s vast array of CBD products are full-spectrum, broad-spectrum, and isolate. Read on to learn a bit more about each.

Three Types of CBD

According to Medical News Today, the main difference between the types of CBD has to do with the compounds they contain. Therefore, depending on the percentage of compounds, CBD will fall into one of three main categories.


CBD products which contain numerous naturally occurring cannabis plant extracts like terpenes and other cannabinoids – most importantly, including up to 0.3% THC – fall into the full-spectrum CBD category. Full-spectrum CBD is popular because the compounds complement each other, which helps to increase the potency. The flavor profile is also stronger with full-spectrum CBD, creating a “hempy” taste that may or may not be your cup of tea.


Broad-spectrum CBD, on the other hand, can also contain numerous compounds of the cannabis plant, but is entirely free of THC. Broad-spectrum extraction seeks to maintain as many compounds and terpenes as possible, except for THC. This way, the compounds are still able to complement each other without any effects from THC getting mixed into the picture. If you’re looking for CBD products that you can easily and safely use if you’re worried about passing drug tests, broad-spectrum is your best bet.

CBD Isolate

Isolate is pure CBD, so it’s also completely free of THC. But it’s usually much more processed and typically comes in a crystal form that is then ground up and sold as a powder. The resulting product will be almost entirely CBD, but everything else has been removed, so you’ll receive none of the complementary effects that arise through the presence of other compounds. CBD isolate may be less effective from a potency standpoint, but it is another safe option if you’re worried about passing a drug test.

Do Your Due Diligence

There are three main reasons that CBD would trigger a positive on a drug test: if the CBD is full-spectrum, if the products are mislabeled, or if there has been cross-contamination. The final two points are out of your control, but luckily, it’s pretty simple to steer clear of potential issues resulting from the first point. All you have to do is check the label to find out which type of CBD is contained in the products. Next, always check the third-party lab reports or Certificates of Analysis, known as COAs.

At Highline, we keep the COAs for all our products handy on one page – just click the link or check it out in the footer. These reports will give you a breakdown of all the compounds in the CBD products. For example, our CBD Day Gummies for Focus include 9.580 mg of CBD per serving, while the THC is ND, short for Not Detected. If you see that ND, you’re in the clear!

The Major Takeaway for Will CBD Show on Drug Tests?

The bottom line when it comes to CBD on drug tests is that you should avoid full-spectrum CBD if you have a drug test in the near future. This type of CBD may inadvertently trigger a positive due to the small presence of THC. Broad-spectrum CBD or CBD isolate should not show up on drug tests as they do not contain THC.

At Highline, you can be rest assured that we use broad-spectrum CBD in all our products, from our OG CBD Anytime Gummies to our fan-favorite CBD Night Gummies for Sleep to our classic CBD Oil and everything in between.
