Does CBD Show Up on a Drug Test?

Cannabidiol (CBD) is a naturally occurring chemical compound derived from the cannabis plant, but doesn’t cause a “high” like its intoxicating cousin, delta-9-tetrahydrocannabinol (THC). 

You’ll usually find CBD in a variety of tobacco products like vapes, edibles, and smokables. And, though commonly sold in stores around the U.S., you may be concerned that the small amount of THC in CBD products could make you fail a drug test.

Whether you have to undergo testing for an employment opportunity, a medical diagnosis, or any other reason, it may be pertinent to know whether or not CBD could affect the test outcome. With that being said, let’s explore the burning question: will CBD show up on a drug test?

Will CBD Make You Fail a Drug Test?

CBD is not likely to make you fail a standard drug test. However, it depends on the type. Isolate CBD products contain no THC, so it will not show up on a drug test. Full-spectrum CBD, however, contains up to .3% THC. In this case, it is possible to test positive for marijuana in some rare instances. However, it depends on the amount and quality of hemp you’re ingesting.

Metabolism, weight, diet, and frequency of use all contribute to how long CBD or THC lingers in your system, and differs from person to person. However, a compilation of studies published in Frontiers in Pharmacology found evidence that the estimated half-life of CBD was two to five days after chronic oral administration and one to two days for smoking.[1]

Another factor that can affect the level of THC reported is the way in which the test is administered. For example, a hair sample can detect repeated drug use up to three months before the test, whereas a urine sample normally captures drugs used only a few days or weeks prior.

While there are no specific studies demonstrating how long CBD is detectable in urine, a commonly referenced study from 1991 shows that the average person can expect CBD to be completely out of their bloodstream in about a week. So, it’s safe to say that you should give yourself about a week before getting drug-tested to be sure there is no THC in your urine sample.

Finally, it should be noted that since the majority of CBD products are classified as a supplement by the FDA, there is more relaxed oversight on the purity of such products. In other words, there may be risks of cross-contamination with THC, especially from companies that also produce marijuana-based products. This risk simply depends on the certain manufacturer’s methods of production.

Consuming CBD Risk-Free

If you’re nervous about failing a drug test, but still want to take advantage of the many benefits of CBD, there are a of couple tips you can follow:

  • Use only CBD isolate products that contain no THC and may be consumed on their own. The only way to truly be sure about passing a drug test is to not ingest THC and marijuana products.
  • Since THC is stored in fat cells, regular exercise and a healthy diet over the course of a few weeks has been shown to slightly shorten the amount of time the cannabis compound stays in your system.

One final note – you should always understand your rights. For example, while there are no legal actions you can take to avoid pre-employment drug screening, current employees who are forced to undergo testing may be able to challenge specific requests. Reach out to a legal professional in your state or locale for information about your unique situation.

Overall, CBD products shouldn’t show up on common drug tests. As long as you properly prepare yourself with the right information, you can take steps to avoid failing a drug test and continue enjoying the benefits of CBD.
