Can CBD Oil Show Up On a Drug Test?

Can CBD oil show up on a drug test? This is one of the most frequently asked questions I’ve heard as a CBD writer, and it’s a legitimate question for folks concerned about their jobs.

Since taking a big step into the spotlight in December 2018 with the passing of the 2018 Farm Bill, CBD has drawn the attention of much of our country and much of the rest of the world. People are starting to do more research and are trying CBD as a natural health alternative for many things including pain relief, anxiety, and insomnia.

But many people still have questions in their minds that are leaving them feeling a bit wary of CBD. One of these questions is whether or not they would have CBD Oil show up on a drug test. There is still a lot of misconception and rumor out there regarding CBD, and there are people who are worried about even trying CBD Oil for fear that it would show up on a drug test at their place of work.

So let’s unpack this a little bit and see if you have to worry about having CBD Oil show up on a drug test.

What Is CBD Exactly?

CBD, short for cannabidiol, is a therapeutic cannabis extract that provides the many health benefits of cannabis without the psychoactive high.

While you can extract CBD from both cannabis plants–hemp and marijuana–CBD extracted from hemp is the only kind of CBD oil that is currently legal across the country. And one of the biggest and most crucial differences between hemp-derived CBD and marijuana-derived CBD is the amount of THC found in each plant.

THC, or tetrahydrocannabinol, is the element in cannabis that causes the “high” we all know of, and this is the element that caused the demonizing of cannabis plants as a whole and their eventual banning in the Controlled Substances Act of 1970. While THC is present in both hemp and marijuana, the only was that a cannabis plant can be designated as hemp is if there is less than 0.3% THC content in the plant.

When CBD Oil is extracted from hemp, there is little to no THC in the oil, with 0.3% THC being the most that should be in the product.

The main thing that would come into play here is the purity of the CBD Oil. 100% pure CBD would not show up on a drug test, because marijuana drug tests look for signs of THC.

Unfortunately, it’s not necessarily as simple as just that…

About the Drug Test…

And according to the US Drug Test Centers, “While research has shown that it’s unlikely that CBD products alone would lead to a positive result on a drug test, it’s important to note that CBD was found to interact with the body’s metabolism of certain compounds. What this means is that CBD users who also use marijuana may actually show higher levels of THC for a longer period of time than when using marijuana alone. So, it would seem that CBD alone is not enough to raise any red flags on a drug test…”

It’s true: if the product you are taking is 100% pure CBD and you aren’t taking it along with any other drug substances, then it shouldn’t show up on a drug test. The problem with this is that with the newness of the industry, there is very little regulation ensuring that a product is 100% pure CBD if it claims to be.

Legally, hemp-derived CBD products are allowed to contain up to 0.3% THC–the normal amount of THC found in hemp–but they have to disclose it to consumers. While this amount of THC isn’t enough to have any kind of psychoactive effect on a person, there is a chance that even that tiny amount of THC could potentially show up on a drug test, but only if you are taking dosages of 1000-2000mg on a daily basis.

Honesty and accuracy in marketing have become definite problems with a lack of regulation. A study done in 2017 found that roughly 7 out of 10 CBD products didn’t contain the amount of cannabidiol that was stated on the label, and about 1 in 5 contained THC, whether they advertised that or not.

So while pure CBD oil wouldn’t show up on a drug test at all, there is a problem that’s posed to the public: If many of the CBD products that you can find online aren’t being advertised accurately or honestly, how do you know which brands you can trust?

How Can You Safely Proceed Forward?

Third-Party Testing

If you are looking for CBD products for your personal use online, there is a way to know whether or not the product you are purchasing is what you want and what is advertised. Always make sure any CBD product that you buy online is third-party tested. When a product is third-party tested, it means that it has been evaluated by a reputable third-party lab to ensure that the contents of the oil truly are what they are being advertised as.

Third-party testing not only ensures that you are getting exactly what you are looking for, but it also shows the good reputation and intentions of the company that you are purchasing from. ALWAYS check for third-party testing before purchasing a CBD product online. This is a way you can ensure that 

Disclose Your CBD Use to Your Workplace

Many people use CBD on a daily basis as a natural health alternative for an ailment they have.

If you are one of those people that needs to take CBD Oil on a daily basis, you can let your managers at your workplace know in case there is a random drug testing. That way they are in the loop and can take your CBD usage into consideration before jumping to any false conclusions.

Holding Off

If you don’t need to take CBD on a daily basis and you know that you could be drug tested at work in the near future, you could always hold off on taking CBD for the time being as well. 


Theoretically, having CBD Oil show up on a drug test should be relatively impossible if you are using 100% pure CBD Oil or CBD Oil containing less than 0.3% THC.

The one thing to keep in mind is that the CBD industry isn’t very well-regulated yet, so make sure that you are checking products for third-party testing before you purchase them. Do some thorough research and you should be able to find a reputable CBD company with quality, accurately-advertised CBD products.
