How Long Does CBD Oil Stay in Your System?

How Long Does CBD Oil Stay in Your System?

There’s a lot of buzz surrounding CBD oil products. And there’s no wonder why: it has been shown to relieve pain, inflammation, depression, and nausea as well as fight off cancer cells and manage epileptic seizures.

But there are still a lot of questions being asked about CBD. Two that come up often are, “does CBD get you high?” and “does CBD show up on a drug test?”

Does CBD get you high?

To start with, let’s tackle the first question since it’s important for answering the second question. CBD (cannabidiol) is one of many Cannabinoids found in Cannabis. It is extracted from hemp rather than marijuana. CBD does not give a “high” feeling. 

THC, found in marijuana, is responsible for the feeling of being high. Since hemp contains less than 0.3% THC, hemp-derived CBD products contain little or no THC. Although trace amounts of THC can sometimes be found in CBD products, there’s not enough to affect your body. Moreover, CBD has a natural ability to block THC’s ability to activate CB1 receptors in cells. The activation of these receptors is what causes a high feeling. So the ratio of THC to CBD in hemp products are not going to produce a psychoactive effect. But, will you pass a CBD oil drug test?

Does CBD show up on a drug test?

Many employers require drug testing. Sometimes it’s to ensure maximum productivity and safety in the workplace. Other times it’s required by law or simply a matter of avoiding any legal risks that may come along with someone who is impaired at work.

Employers are primarily concerned about impairment. CBD does not cause any psychoactive effects, so it does not cause impairment. Since drug tests are designed to detect drugs that cause impairment, they usually do not test for CBD, you will most likely not have to take a CBD oil drug test (there are some exceptions which we will talk about later). 

As we talked about earlier, hemp-derived CBD products can still contain trace amounts of THC. Many may be concerned that this will show up on a drug screen. There are two common types of drug screens: a ten-panel screen and a five-panel screen. Both of these types of tests do check for THC-COOH—which is metabolized THC—as well as non-metabolized THC. 

It is possible that large amounts of CBD-product consumption (1,000-2,000 mg each day) could contain enough THC to show up on a test and produce a false-positive result. However, it is highly unlikely. Even with heavy CBD use, the THC levels would not meet the federal limit which is 50 nanograms THC metabolite per milliliter of urine.

There is no specific CBD oil drug test. When they do test for CBD it is for general CBD, not just CBD oil. 

If the CBD product you use contains 0% THC, you would not test positive on a drug test (unless there’s an error with the test) because drug screens do not usually check for CBD. There are CBD oil drug tests being developed for employers, but most don’t care about their employees using CBD. If you’re not sure if your employer is testing for CBD, it’s best to be upfront with your employer and let them know about CBD usage, so there are no surprises. Be clear as to why you use CBD and make sure they are aware that it is a natural non-psychoactive supplement. 

Medical drug tests

Not all drug screening is done by employers. There are also many cases where tests need to be given by medical professionals. While an employer’s goal for a drug screen is often to ensure they have productive employees, a medical professional’s goal is to keep you safe. When administering drugs, it’s important to know that there are no other drugs in the patient’s system that could cause a bad reaction when mixed with other medications. For this reason, when undergoing a procedure, you may be required to take a drug test. In this case, it will most likely test for CBD in the bloodstream. If you know that you are going to undergo a procedure, it’s important to consult your doctor a week or two beforehand. They may require you to stop using CBD for a week before the procedure. 

How long does CBD stay in the bloodstream?

If you know you will be tested for CBD ahead of time, the best course of action may be to stop using it beforehand. So how far ahead do you need to stop using CBD oil, and how long will it stay in your system?

The answer to the question isn’t quite straightforward. It can depend on many factors including how much is used, how it is used, and your bodies ability to filter it out. Moreover, this topic has not yet been extensively studied—so it’s not entirely clear. 

One study done in 1991 looked at 14 Huntington’s disease patients who took large amounts of CBD for a six-week period. After taking 700mg of CBD each day during the six weeks, they stopped taking CBD altogether. After one week without any CBD, their blood was tested for any amounts CBD. The amount of CBD in their bloodstream was practically untraceable. However, this is dealing with blood—not urine. Although CBD did not show up in their blood, it does not necessarily mean it could not show up in a urine drug test. 

There are currently no studies showing how long CBD will remain in urine. However, many experts of CBD agree that it should take no longer than two weeks for CBD to be undetectable through urine. Of course, this is only speculation, and it has not yet been explored scientifically. 

Final thoughts 

Although CBD is becoming more and more popular for its powerful therapeutic and medicinal uses, there’s still a lot of misconceptions about what it is and what it does. Because it’s often associated with marijuana and THC, many people are reluctant to give it a try. 

All in all, most employers are fine with CBD use. As for the trace amounts of THC, drug tests will more than likely not produce a false positive because of them. But of course, if you’re not sure, ask your employer about their rules and regulations.
