Does CBD Oil Show Up on Drug Tests?

Those who are first approaching the CBD industry are usually curious to know whether or not CBD is able to get you high. Fortunately, this is not a chemical found in the hemp plant that is able to produce the psychoactive effects associated with THC. However, because it is associated with THC, it poses an even more important question: is CBD a substance that can appear during a drug test? After all, CBD is found in the same plant as THC.

This is a question that needs to be answered if you want to avoid being fired from your job or facing repercussions simply for using a CBD product. If you are curious as to whether or not it can appear on your next drug test, take a look at the comprehensive article below to learn more about CBD and its potential impact on your employment.

Does CBD Oil Show Up on Drug Tests?


Will CBD show up on a drug test? The answer to this question is actually no but it may not be for the reasons that you suspect. CBD doesn’t show up on drug tests because there aren’t any drug tests that have been developed to date that are designed to look for it. While your test will be able to pick up most illegal substances, it will never be able to detect any amount of CBD in your system.

In addition to the fact that there is no possibility of detection, there is also the fact that there are no tests out there that could detect CBD if an employer wanted to. If these tests were developed, it would cost employers extra money and it would be doubtful that they would go through the added effort and cost. Overall, it is relatively certain that you will be safe while using CBD and will not get in trouble at work for it.

What This Means for Employers

If you’re an employer and you were wondering if you were able to test for CBD, the unfortunate answer is that it is doubtful that you will be able to. There may be tests out there but, as we said above, it would cost you extra money and time in order to have these tests administered.

CBD is just a chemical compound that is said to help deliver medical benefits and doesn’t carry any of the recreational uses or dangers. 

Can Drug Tests Detect CBD?

Take a moment to think about the last time you took a driving test. Did they ask you about math questions? Did they see if you were still capable of speaking Spanish after taking it in high school? If it was a normal driving test, they probably did not and this is because the tester is only looking for your driving abilities and not any of your other abilities.. In a similar way, drug tests only test for certain substances. These substances are often the highly-addictive, recreational drugs that could pose a danger on the work site or may produce undesirable side effects that could result in less productivity.

Because CBD has not been proven to be a recreational or harmful substance, there has been no need to test for it and, because of this, it will not show up on drug tests. Those who are using CBD can rest assure that the CBD will not show up on their drug tests as long as these tests aren’t looking for them.

What If My Cannabidiol Has a Very Small Amount of THC?

This is the catch and this is where you need to be very careful when you are using CBD. It is important to know that not all CBD is free of THC. If you have enough THC in your substance, you do run the risk of showing up as positive for marijuana in your test. This depends upon the test that your employer decides to administer. Full spectrum CBD will definitely contain THC.

That being said, the chances of extremely low doses of THC in CBD products showing up on drug tests is equally low. However, it may happen and you should be aware of this possibility in case you need to explain to your employer why these results are being produced by your drug test.

Legal THC content in Legal CBD

The best way to ensure that you are less likely to encounter trouble during your drug test is to make sure that your CBD contains a legal amount of THC in it. For those who live in areas where recreational or medicinal marijuana products are legal, you may encounter CBD products that contain higher concentrations of THC for one reason or another. Depending on the CBD to THC ratio, you might see more in your edibles. While these psychoactive levels may help to produce certain effects when they are added to Cannabidiol, they increase your likelihood of showing up as positive on a drug test. Make sure that your products contain a legal THC level when you are shopping for a product, which is typically around 0.3 percent. 


There are several ways to avoid showing up positive on a drug test, even though it is doubtful that this would happen. The rest of this article will explore some of these preventative measures that you can take even before a drug test is coming up.

Full Spectrum vs Isolate CBD

One of the most important things to know is that not all CBD products are made the same. Most lotions, vape juices, cooking oils, tincture oils, and other products are made from a form of CBD known as full-spectrum CBD.

What is full-spectrum CBD?

Full-spectrum CBD is when it also contains other cannabinoids or terpenes in that specific product. The oil that is produced contains not only CBD but other hemp byproducts such terpenes and even possibly THC. These products then all mix together to make the oil that is found in your CBD products and this small amount of THC is what we are worried about here.

If you are truly worried, there is another form of CBD that is much safer. This is known as CBD isolate. It has undergone another filtration process known as winterization. In this process, the CBD is cooled to a point in which it freezes and the pure Cannabidiol active ingredient can then be separated from other substances. This isolate is then packaged and sold by itself as pure CBD, which can serve you better if drug tests are on your mind.


Having a job is really important and it is reasonable to not want to take any risks that could lead to your termination. If you really want to make sure you don’t turn up positive on a drug test, use these valuable tips provided below.

1. Isolates Are the Only CBD That Contain No THC

When it comes to CBD products, the only product that is going to give you an experience that is 100 percent THC-free is CBD isolate. Isolate is CBD in its purest form, separated from all other hemp-based ingredients. This means that not only will you not only get it without THC but you may even get an improved experience due to the fact that it is a far more potent product when compared to normal CBD products. 

2. Check Certificate of Analysis Reports

COA reports, also known as Certificate of Analysis reports, give the consumer a comprehensive overview of the chemical makeup of your product. This analysis shows all of the ingredients like cannabinoids and terpenes that are found in your CBD product. It will also tell you exactly how much THC is present in your mixture. If you’re really concerned about THC levels, taking a look at the COAs before you purchase a product. It will go a long way in making sure that you don’t get caught in a drug test.

3. Check for THC Contamination

The biggest problem with products like CBD is that you can never be exactly sure where it comes from. Not all vendors are reliable as many are allowed to get away with things due to the fact that the CBD industry is still in its infancy. As such, you may have purchased a product that contains way more THC than is actually advertised. Make sure to check for this kind of contamination before you begin using any product regularly by checking out product reviews. There is are a lot of reviews and testimonials people are posting about companies and products

4. Smoking or Vaping CBD After Using Marijuana in It

On a similar note, you can be contaminating your vapor with THC without even knowing it. While the majority of this article has been geared towards users who are looking to steer clear of THC altogether, there may be users who are still interested in indulging hemp flower through a vape. Dry herb vaporizers are generally used for cannabis. When you burn off the resin and inhale the vapor, it can potentially release burned THC.

Plenty of people do this and are safe but you could be putting yourself at risk if you are using the same tools to absorb your THC and your CBD.

If you have refilled your chamber with THC oil and then didn’t properly clean it out or left a small amount of herbal weed then put CBD oil in your vaporizers, you could be vaping both substances at once. It is better to play it safe and to make sure that you always use separate tools for different substances.


Many people ask whether or not CBD is able to produce a high but not many ask whether or not the substance will end up on a drug test, which is equally as important. The truth is that, while CBD does not, certain CBD products may still appear due to the presence of THC in the solution. If you are looking to avoid losing your job over CBD products, make sure to use the information above to use your CBD more intelligently and remain completely clean come test time!
