does cbd show up on a drug test?

You take CBD oil regularly and are feeling great. But now you have a drug test coming up for a new job or a random check that could be required at any time, and you’re wondering if CBD can show up on a drug test. The short answer is no, CBD probably wouldn’t show up on a drug test. However, that’s not the entire answer. Read on to learn more about whether or not CBD can show up on a drug test.h


To better understand whether CBD will show up on drug tests, you need to know the difference between THC and CBD. Both CBD and THC come from cannabis, a family of plants that include marijuana and hemp. These plants are bred to contain different amounts of THC. Marijuana contains high amounts of THC, while hemp contains higher amounts of CBD. The THC is in the compound in marijuana that produces the “high” users experience. It’s THC that drug tests are looking for, not CBD. CBD is non-psychoactive and does not produce a “high,” so it’s not concerning to administrators of a drug test.

Hemp-derived products are high in CBD and low in THC. In fact, hemp products are federally required to contain less than 0.3 percent THC content. Hemp-derived CBD can be sold in all 50 states because of the low levels of THC it contains.

However, some states have legalized medical marijuana, and in those states, it’s possible to sell marijuana-derived CBD. Marijuana-derived CBD can have far more than 0.3 percent THC, especially if it’s marketed as full-spectrum. Full-spectrum CBD contains more of the plant compounds, including terpenes, flavonoids, and other cannabinoids, such as THC. Not all manufacturers disclose where their CBD is derived from, so it can be difficult to assess how much THC a product contains.

It stands to reason that if there’s a large amount of THC in your CBD oil, then it’s possible that it could show up on a drug test. Therefore, you need to thoroughly research your CBD product and determine how long CBD stays in your system. If you’re unsure where the company derives their CBD from, reach out and ask. Also, be sure to discuss the levels of THC present to assess whether it contains less than the federally-accepted 0.3 percent THC.

How Much THC Must Be Present to Show Up on a Drug Test?

how much thc must be present to show up on a drug test?

But if even hemp-derived, fully-legal-in-all-50-states CBD contains 0.3 percent THC, can you test positive for THC if you take enough of it? Let’s take a look at how much THC must be present to show up on a drug test.

In 2017, the Mayo Clinic established cut-off values in regard to drug testing when it comes to the U.S. federal guidelines. That means that even though you may have a tiny amount of a substance in your system, it would still indicate a negative drug test if the amount present is under those established thresholds.

  • Urine testing. Urine testing for cannabis is probably the most common type of drug test. However, it’s also the least precise. THC is only detectable in your urine for a few days to a few weeks. You’d have to consume over 1,000mg of CBD oil per day for it to even show up on this test. To meet the U.S. federal guidelines as a positive test, THC must be present at a concentration of 50 nanograms per milliliter or higher. However, different employers may have specific requirements and may test for different cut-off concentrations.
  • Blood testing. Blood tests are far less common for THC testing because THC is only detectable in the bloodstream for up to five hours. That’s why blood testing is most often used in cases of drivers suspected of driving under the influence. You’re just as unlikely to fail a blood test as a urine test by using CBD products (and won’t display other signs of impairment), unless you use a CBD product with a high enough THC content.
  • Saliva testing. Saliva testing is rare when it comes to drug testing, but THC is detectable in saliva for about 72 hours. No cut-off guidelines have been established for THC concentration in saliva testing.
  • Hair testing. Testing hair is not common, but it is accurate, as THC is detectable in the hair for up to 90 days. There are currently no established cut-off limits for hair testing.

Can CBD Trigger a Positive Drug Test?

The bottom line is that CBD cannot show up on a drug test. Drug tests look for THC, not CBD. However, if you use CBD products with a high enough THC content, it can trigger a positive drug test. That’s why it’s important to research the company that manufactures any CBD product before purchasing. Be certain that the company you buy from meets federal guidelines and regulations. If you use a hemp-derived product that meets all the current guidelines, then you’ll be in the clear.
