CBD (cannabidiol) oil is a popular product for everything from pain control to anxiety to promoting sleep. However, with the rise of CBD comes the concern about failing a drug test due to detection of CBD oil. News stories are emerging across the country involving famous sports players, employees of companies, and others who have gotten positive drug screening results for the presence of THC—the psychoactive component of marijuana —even though CBD oil is said to be THC-free.
What are the odds that CBD oil users will test positive when subjected to illicit drug screenings, and what can be done to prevent it?
Does CBD Oil Contain THC?
When a drug test is performed, the active chemical in marijuana that gets detected in a positive screening is THC. However, most people are under the impression that CBD oil is THC-free.
As it turns out, depending on the source of the cannabis that is used to produce the CBD oil, some products do contain traces of THC (including low-quality isolates and many full-spectrum tinctures).
Breakdown of Cannabis
Cannabis is the umbrella term describing hemp and marijuana plants—two different varieties of the cannabis genus. Both marijuana and hemp can be described as cannabis plants; however, it is important to note that they are still two separate plants.
CBD is one of many active chemical compounds in the cannabis plant. One reason it’s gaining momentum in popularity is because it is said to lack the component of the plant that causes a person to get high, which is called THC (tetrahydrocannabinol).
The primary difference between hemp and marijuana is that hemp is nearly void of THC. In fact, a cannabis strain must contain less than .3 percent THC to be classified as hemp. This is the reason hemp can be legally sold as various products.
Most CBD products are made from hemp, not marijuana.
There are many distinctions between marijuana and hemp that relate to CBD oil. Marijuana contains both THC (the psychoactive component) and CBD, whereas hemp contains CBD and only trace amounts of THC. Hemp contains many cannabinoids—CBD is only one example.
There are several techniques for extracting CBD oil from the cannabis plant. The extraction method determines whether the active CBD compound gets processed as a “full spectrum oil” or an “isolate.” A CBD isolate is a pure compound with no other active compounds or cannabinoids at all. A full spectrum oil contains other active plant compounds in addition to the CBD such as CBN (cannabinol) and cannabis terpenes (the part of the plant that gives the plant its aroma), and more.
Study of CBD Oil
While some CBD oils claim to be isolates, they may be full spectrum oils and actually contain more cannabinoids (such as THC) than they claim.
In a study conducted by researchers from the Lautenberg Center, researchers discovered that CBD was more effective for treating inflammation and pain when used with other cannabis plant compounds derived from a full spectrum product over a CBD isolate product alone. This is one reason that full spectrum products (those containing THC) are popular.
However, the distinction between full spectrum oils and isolates make all the difference if you are being tested for drug use.
Reasons for Failing a CBD Drug Test
There are several common reasons a person fails a CBD drug test.
1. Using Product With THC
The most common reason for a failed CBD drug test is that a person is using a CBD oil product that contains THC. Sometimes, this may be because a person purchases a low-quality product that does contain a small amount of THC—most manufacturers will claim their products do not contain THC, but this is not always the case.
2. Cross Contamination of THC
Very small amounts of THC present in the material that CBD is extracted from can get into the CBD oil in high enough amounts to result in a positive drug test. This scenario may be more apt to occur when CBD oil is purchased from cannabis dispensaries in places where cannabis is legal, as opposed to an online retailer.
3. Mislabeling of Products
CBD oil extracted from hemp is not supposed to have any more than .3 percent of THC. However, it’s not uncommon for sellers to mislabel their products as THC-free hemp when in reality, it’s a low-quality oil extracted from marijuana, which does contain THC.
In fact, one study discovered that almost 70 percent of the CBD products sold online were not labeled properly, “causing potential serious harm to its consumers.” The reason for this widespread mislabeling is that CBD products are not strictly regulated by the FDA.
4. Secondhand Exposure to THC
Inadvertent exposure to marijuana (via secondhand smoke) is unlikely to be enough for a person to get a positive drug test result, but it is possible. Being in a room with heavy pot smokers for several hours may cause the inhalation of enough THC containing smoke to result in a positive test.
A more likely secondhand exposure scenario is a positive marijuana hair test, resulting from direct contact with marijuana paraphernalia or from another person having THC on their hands.
For instance, if someone who had direct contact with marijuana then touched your hair, you could feasibly receive a false positive on a drug screening that tests your hair.
5. CBD Oil Breaks Down in The Digestive System
Some sources report that in rare cases, false positive test results have come from CBD oil that breaks down into very small amounts of THC in the stomach. Other studies, however, have refuted this.
The conclusion is that it’s still theoretically possible for traces of THC metabolites to be present in the stomach acid in the instance where “less-purified CBD productions” are ingested.
How to Avoid a Positive CBD Drug Test
If you take CBD oil, there are measures you can take to try to prevent failing a drug test.
- Do thorough research to ensure the CBD product you’re using is pure and that the company is legitimate.
- Ensure that the CBD oil is an isolate product extracted from a viable industrial hemp supply, and is not a low-quality tincture.
- Ask questions about product processing techniques and the possibility of cross-contamination.
- Avoid secondhand exposure to marijuana use via pot smoking or hair contact from THC users.
A Word From Verywell
In theory, getting a false positive on a drug test from CBD oil should be relatively impossible from pure CBD oil containing less than .3 percent THC. However, because CBD oil is not very well regulated, there is no guarantee that a product contains pure CBD oil, or that its concentration is at a safe or effective level. It is best to use utmost caution and do your research when purchasing a quality CBD oil product to ensure its purity, especially if you need to undergo drug screenings.

Cannabidiol (CBD) has recently surged into the therapeutic spotlight for its perceived anti-inflammatory, anti-anxiety, pain-relieving, and seizure-suppressing properties. It can be found in health and wellness aisles across the world — perhaps even at your local Walgreens or CVS — and comes in many forms, some of which include CBD oil, tinctures, edibles, elixirs, and more.
CBD is a non-intoxicating compound found in cannabis, which some say provides the benefit of relaxation without the high that THC provides.
Although hemp-derived CBD products are available in states where recreational cannabis isn’t legal, some people might worry whether their use of CBD oil will show up on a drug test. Even in states where it is legal to buy THC-heavy cannabis from a retail store, some employers still screen employees for cannabis use. It’s a valid concern considering that even CBD products derived from hemp are legally permitted to contain traces of THC, 0.3% or less to be exact, perhaps leaving some consumers to wonder whether there’s a small amount of THC in their CBD oil — and whether that will show up on a drug test.
“I think that people who are afraid of testing positive should use isolate that is third-party tested to have no THC or extremely minute trace amounts that result in no THC. That’s the simple and safest thing,” said Dr. Joseph J. Morgan, Professor of Cannabis Education at the University of the Sciences in Philadelphia and medical adviser.

While there are certain CBD products, such as distillate and crystalline, that contain zero THC, the fears of inexperienced consumers may still persist. Like most things in the constantly evolving cannabis space, there are a number of factors to consider.
Should you worry about CBD oil showing up on a drug test?
In most cases, it’s highly unlikely that CBD oil will show up on a drug test. Most employment drug tests specifically look for the presence of THC or THC metabolites. Most employers abide by the guidelines set forth by the Substance Abuse and Mental Health Services (SAMHSA), which includes detection for THC but not CBD.
But what if your CBD oil contains small traces of THC? Many top CBD manufacturers have products with no presence of THC. Although hemp-derived CBD products are legally allowed to contain a maximum of 0.3% THC, some prospective consumers may still be reluctant to try CBD that contains even a small amount of THC. Thankfully, there are ways to create hemp-derived CBD products without any hint of the intoxicating cannabis compound.
For instance, producers can isolate CBD compounds after the oil is extracted from the stalks and seeds from hemp plants. This process leads to pure CBD, effectively eliminating any THC and other plant-based constituents from the end product. Once isolated, the CBD can be mixed with liquid oils that contain fatty acids to improve absorption.
But how can you tell how much THC, if any, might reside inside your CBD oil? Can you really trust everything the label on the side of the bottle? The safest bet is to look for well-known CBD products that are independently tested.
“Buy from reputable forms that are third-party tested that have batch numbers, lot numbers, and retained batch samples. If they claim that either that their plants are genetically engineered for no THC or they use methods that purge THC, to make sure that that’s third-party validated,” Morgan said.

There are also different types of drug tests that can be used, all of which present different detection thresholds. For instance, a hair test is made to detect habitual substance use, so it will probably not raise any red flags even if you are consuming CBD oil that has low levels of THC.
Urine and oral drug screenings have a lower threshold for detection, so there is slightly more risk with these tests, according to a December 2018 article published in Vice. While it’s possible that the small amounts of THC that exist within a CBD product could accumulate and show up in a drug test, it’s still highly unlikely.
Under the SAMHSA framework, the cutoff limit for the presence of THC is 50 nanograms per milliliter. Following these guidelines, if an extremely high dose of 2,000 milligrams of CBD oil that contains 0.3% THC was consumed, there’s a slim chance of receiving a “false positive” result on a urine screening.
Is there such a thing as a CBD oil drug test?
While it may be uncommon for anyone to screen for the presence of CBD, does a CBD oil drug test even exist? Technically, since CBD is a chemical that your body metabolizes, a specific test can be developed to detect it. But the average drug test will not identify any usage of CBD oil.
To obtain a CBD oil drug test, an employer or entity would have to pay a testing company an additional charge to change their testing regimen to include CBD. When you consider that this non-intoxicating compound won’t get you high or impair your ability at work, there’s really no need for a CBD oil drug test.
If you’re concerned that using CBD-infused products will cause you to fail a drug test, there are certain precautions you can take to ensure that no THC enters your system. Look for producers who create high-quality CBD products that contain zero THC, such as distillate or crystalline products.
