Does CBD Oil Show Up On A Drug Test?

Does CBD Oil Show Up On A Drug Test?

Whether you’re curious about the buzz around CBD and want to try it for the first time, or you’re someone who already uses CBD regularly, you may find yourself worrying about it showing up on a drug test. As CBD grows in popularity, rookie and seasoned consumers alike are asking: does CBD show up on a drug test? The simple answer is that it’s very unlikely to. 

That’s because the majority of drug tests aren’t screening for CBD in your system—they are screening for THC (tetrahydrocannabinol). Since some CBD products contain trace amounts of THC (up to 0.3% by volume is legally allowed), in rare cases consuming a CBD product could lead to you failing a drug test if enough THC is present. 

If you want to enjoy CBD’s various benefits but are concerned about a CBD drug test, it’s important to learn more about the different types of CBD so that you can avoid failing a drug test.

Does CBD show up on drug tests?

Drug tests screen for the presence of certain illegal drugs in your urine, blood, saliva, hair, or sweat. At different points in your life you may be asked to take a drug test by landlords, employers, doctors, and even traffic cops. Since failing drug tests can negatively impact your life, it’s normal to wonder: does CBD oil show up on a drug test? In rare cases, CBD products such as CBD oil can unfairly and accidentally lead to a positive test result. Let’s break down why that happens so that you can learn how to avoid it.

Let’s put some worries to rest: there is no such thing as a CBD drug test. Most drug tests do not screen for CBD, but they do screen for the closely related compound THC. Legally, CBD products can contain up to 0.3% THC per volume. That means that even if you consume or use a CBD product that is labelled or represented as “100% CBD” or “CBD only,” there is the possibility that trace amounts of THC have made their way into your body. The drug testing companies that screen drug samples know that many legal CBD products contain trace amounts of THC, so the detection of a small amount of THC won’t cause you to fail a test. The permissible THC limit varies among drug testing companies, but overall there are measures set in place so that CBD users don’t accidentally fail a drug test.

While CBD products are legal at the federal level, the industry as a whole is not regulated by the FDA (Food and Drug Administration). This makes it hard to know if there is a trace amount of THC in the products you consume and if that amount is above 0.3%. Mislabeling and cross contamination have also been known to occur. If you are unlucky enough to encounter a CBD product that is mislabeled, or if you are a regular user of CBD products, it is possible that these trace amounts of THC accumulate and cause you to fail a drug test. Educating yourself about the different types of CBD can help you make an informed choice about the products you use and how likely they are to cause a failed drug test.

Does CBD oil get you high?

CBD Oil In A Drug Test

Consuming CBD oil or other CBD products does not get you high. That’s because CBD oil does not contain THC, the compound that causes the characteristic high associated with smoking marijuana. CBD oil is a product derived from CBD, which is a cannabinoid naturally found in hemp and cannabis plants. CBD can be added to tinctures, creams, and even to food and drink. One of the most popular CBD products is CBD oil, which can be taken orally (under the tongue), or used in a vape pen. 

CBD offers many positive health benefits, like relieving anxiety and stress, and encouraging relaxation. The relaxation and anxiety relief you may experience after consuming CBD or applying it topically is not equivalent to the psychoactive effects of THC.  The trace amounts of THC sometimes found in CBD products are low and extremely unlikely to make you feel high


While CBD and THC both occur naturally in cannabis and hemp plants, they have radically different effects on your body and mind. The most significant difference is that THC has psychoactive effects, producing the characteristic high that is associated with smoking marijuana. CBD does not produce a high, but can relax the body and relieve stress or tension. 

This difference has to do with the way our bodies interact with CBD and THC after they are ingested. Both CBD and THC interact with cannabinoid receptors in your body, known as the CB1 and CB2 receptors. These receptors are part of your Endocannabinoid System, or ECS for short. The ECS takes part in regulating all kinds of functions in your body: from appetite, mood, sleep, and memory to fertility and reproduction. While THC interacts with CB1 receptors by activating them and producing a sense of euphoria, CBD is a CB1 blocker and actually inhibits any intoxicating effect from taking place. When taken together, CBD can actually block the intoxicating effects of THC.

Types of CBD

Now that you know the difference between CBD and THC, let’s break it down even further and learn about the three most common types of CBD: Full Spectrum, Broad Spectrum, and CBD Isolate.

Full Spectrum

You may have guessed from the name alone, but Full Spectrum CBD contains ALL of the compounds and cannabinoids found in a natural hemp or cannabis plant. These natural plants contain not only CBD, but also CBG, CBN, terpenes, flavonoids, and trace amounts of THC. The benefit of choosing this type of CBD product is experiencing what is commonly known as the “Entourage Effect”: the theory that cannabinoids are most effective when taken together. If you find yourself asking, “does CBD show up on a drug test?”, then this is not a good choice for you. Though the amount of THC found in “Full Spectrum” CBD products is quite low, there are safer CBD options if you have an upcoming drug test.

Broad Spectrum

Broad Spectrum CBD is almost identical to Full Spectrum CBD, but with the trace amounts of THC removed. This is an excellent option for those concerned about THC showing up on a drug test but who still want to benefit from the synergistic “Entourage Effect” found in Full Spectrum CBD products.


As suggested by the name, CBD Isolate is created when CBD is isolated from all the plant’s other compounds. Manufactures undertake multiple processes in order to produce CBD Isolate, which is in crystal form and is 99% pure CBD. The crystals are ground into a powder that can then be made into products. Since CBD Isolate is pretty much guaranteed to contain pure CBD only, it is by far the safest choice when you know you have an upcoming drug test.

What CBD to take if you get drug tested

If you are concerned about a CBD drug test or if you want to know does CBD oil show up on a drug test, your safest option is to consume a product made using CBD Isolate. CBD Isolate is the safest choice because it contains only CBD in its purest form, and drug tests do not test for CBD. Since drug tests are screening for the presence of THC, consuming a CBD Isolate product almost completely eliminates the risk of trace amounts of THC appearing on your test. You can learn more about different types of CBD Isolate in order to avoid failing a drug test.

Final thoughts

As the buzz around CBD grows, more people are trying out CBD products and enjoying the various benefits it offers. If you want to enjoy these benefits without asking yourself does CBD show up on a drug test, do your research beforehand. Buy high quality products from reputable and legal manufacturers that list any trace amounts of THC and do not have a history of mislabeled products. 

A reputable seller will be able to provide information on any trace amounts of THC present in their products, and will differentiate between the three types of CBD: Full Spectrum, Broad Spectrum, and CBD Isolate. To quell any worries about CBD drug tests, choose a product made using CBD Isolate.


High quality CBD products and oils should not contain significant amounts of THC, and should not have psychoactive effects. A quality CBD product will not make you feel high nor impair your judgement in the way consuming THC does. Tests for impaired driving will not test for CBD. However, since CBD can impart feelings of calm and relaxation, it is best to wait a couple hours after consuming before driving so that you are alert.

No, drug tests do not usually check for CBD. Drug test screen for illegal substances such as THC. There is no precedent for you to have to take a CBD drug test. Most drug tests are looking for THC, but since THC and CBD are closely linked, it’s totally normal to be asking, “does CBD show up on a drug test?”
