Does Hemp Oil Show up on Drug Tests?


Hemp oil is a substance from the hemp plant, and is now very popular because of its capacity to heal. Supporters are claiming how they are able to see helpful changes in using hemp oil towards seizures, anxiety, and further health issues. However, this product is currently not yet legalized in all countries around the globe. Even though hemp products states to have below 0.3% THC, these products are still unregulated, which makes its THC levels undependable. 

DEA said in an interview, “for practical purposes, all extracts that contain CBD will also contain at least small amounts of other cannabinoids. Although it might be theoretically possible to produce a CBD extract that contains absolutely no amounts of other cannabinoids, the DEA isn’t aware of any industrially-utilized methods that have achieved this result.”

Hemp oil is indeed going big these days – It’s everywhere right now and even available in stores such as Rite Aid, Walgreens, and CVS. Based on a representative survey done along with Consumer Reports in January 2019, there are over 54 million people who have tried hemp oil and CBD oil, and about 4000 adult Americans are consuming it for anxiety, depression, insomnia, pain, and more health issues. 

The popularity of hemp oil and CBD oil may have one unforeseen side effect, and this is failing a drug test, worst is could even lead a person to lose his or her job. This is the reason why a lot of people are now asking- does hemp oil show up on drug tests, and how long does hemp oil stay in your system? Well, let’s find out the answers as we go on.

Can hemp oil affect your drug test results?

Let’s take into account the experiences of Coni Hass from California and Bianca Thurston from Pennsylvania; they are both using Koi CBD. These two are now claiming how they’ve failed their drug test for using CBD hemp oil that they bought from the company; Thurston even lost her job. A truck operator from New York named Douglas Horn also lost his employment because he took a CBD hemp oil product manufactured by Dixie Elixirs.

Consumer Reports asked a statement from Koi CBD about the complaint. They said, “Koi prides itself on providing the highest quality products while being a leader in the industry. We take claims regarding our products very seriously. We are investigating this matter and the allegations, which at this time, are unproven and unverified. We remain focused on continuing to carefully craft and offer a full array of beneficial cannabinoid products.”

While Dixie Elixirs didn’t answer back to the request for comment. 

Now, how does hemp oil show up on drug tests? According to Barry Sample from Quest Diagnostics, the USA’s largest drug tests administrator, the urine test that is typically used doesn’t hunt for CBD substance but a compound produced by the human body once it absorbs THC. 

“There isn’t going to be a laboratory analytical false positive confusing CBD with a THC metabolite,” Barry said.

He also mentioned how CBD hemp oil and other products could possess more amount of THC than what their labels says. CBD hemp products found online and in local stores should only contain under 0.3% tetrahydrocannabinol or THC, the main compound that could give you the feeling of “high,” typically found in Marijuana. 

Possibly, throughout time, the less quantities of THC that is legalized in CBD hemp products could increase in your body to evident levels. Hemp CBD oils have lesser chances to result in positive in a drug test when you use it in small doses because they lack enough THC level for detection. So, if a person is taking hemp-based CBD, they must consume over 1000mg or 2000mg of CBD, which is really a huge amount, to get positive results. Keep in mind that taking massive amounts of CBD oil can result in a person’s impairment. 

Doses for hemp oil across brands are not standardized, and some vouch for bigger dosage than others. Along with that, CBD hemp oils are not regulated by the FDA, making the products’ publicized THC levels unreliable. The different dose references and the inaccurate THC levels of the CBD hemp products you take could result in having positive drug test results. 

How will you distinguish that the CBD hemp oil is not from Marijuana?

When you test Marijuana, the drug test spot THC and not CBD. However, CBD hemp oils and other products can still have small quantities of THC. Typically, drug tests don’t define the form of component you’ve had, only if you took a product with THC. But, because CBD hemp oils and other hemp products are not regulated, making those THC levels that they write on their labels to be unreliable. So, if you are a person who uses CBD oil derived from the hemp plant, you have to take over 1000mg to 2000mg of CBD to get a positive drug test result. 

How long does hemp oil stay in your system?

When the product you take has THC, even those products from the hemp plants which are low in THC, then hemp oil will stay in your system. The detection gaps for THC may vary on some factors, which includes the weight of the person using it and how it is frequently used. Accordingly, if you consume large amounts of CBD hemp oil, then a drug test will result positively via urinalysis just 30 days succeeding your first use and about 90 days if it’s through hair test. 

Positive drug test results with hemp oil, why does this happen?

Getting a positive result on drug tests is possible even if you merely had CBD products due to the reason of these products will always have a trace of THC. With authorization, hemp oil and other products should only have under 0.3% of THC, and this is still detectable in a drug test, it doesn’t matter how small the amount you’ve taken. This explains why you can get a positive result on a drug test even if you only had full-spectrum CBD hemp oil. 


CBD hemp oil and other hemp products are nowadays very famous due to their medicinal benefits, which include relief from pain, arthritis, seizures, PTSD, and even depression. The fact that it doesn’t partake in any psychoactive effects that give you the feeling of being high (like what Marijuana does) is the best part for a lot of consumers. However, if you take CBD products on a close enough date to your scheduled drug tests, then you may have the possibility of receiving a positive result. On the other hand, how long does hemp oil stay in your system actually depends on your weight, the amount you take, and your age.
