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.

Can Hemp Oil Make You Fail Drug Test?
Like it or not, many job applicants are required to take drug tests. It is mandatory for government employees but some private companies as well. Below we discuss whether hemp oil can make you fail a drug test.
Hemp oil has been dubbed the super supplement because it’s rich in essential fatty acids, minerals, and vitamin E. Plus, this oil is known to help with a variety of conditions, including cardiovascular disease, skin disorders, and menopause symptoms.
In general, there is almost no risk of failing a drug test from using hemp oil. Most of these oils don’t contain any cannabinoids (CBD, which means no THC), so you don’t need to worry about the drug test. Still, it would make sense to know more about the oil to be absolutely sure.
What is Hemp Oil?
Hemp oil, also known as hemp seed oil, comes from industrial hemp, a strain of Cannabis sativa. The plant itself contains very low levels of THC and relatively high levels of CBD. But hemp oil is obtained from industrial hemp seeds which contain even lower amounts of all cannabinoids.
The producers use the cold press method to extract the oil from hemp seeds. The process involves removing the outer husk and de-shelling, before chilling and squeezing what’s remained to get the extract. The dark green oil is not refined and features a full profile of bioactive compounds and nutrients.
More importantly, the final product doesn’t contain any cannabinoids and is not psychoactive. This you can be sure of as the manufacturers want to sell the oil in all 50 states. It’s like get a G rating for a moving versus NC-17. You are certain to make more sales.
Hemp Oil vs. CBD Oil
Both types of oil are derived from industrial hemp, but they shouldn’t be confused. Unlike hemp oil, CBD oil is extracted from the stalk, leaves, and flowers of the plant. It contains cannabinoids and might cause you to fail a drug test – this would depend on the level of THC, the psychoactive cannabinoid.
In fact, CBD oil is behind the wave of marijuana legalization in the US. The various CBD compounds have medicinal purposes but not THC, which is only for getting high. Many opponents of marijuana legalization have accused the proponents for using the medicinal properties of CBDs to push marijuana through, when you really don’t use marijuana to treat diseases – you only need CBD oil.
CBD oil a potent antioxidant, pain reliever, and anti-inflammatory agent.
But, can hemp oil make you fail drug tests?
Hemp oil and Drug Tests
The common urine screening utilizes an immunoassay with antibodies that confirm the presence of THC and other banned substances.
The test looks for 11-nor-delta9-carboxy-THC (THC-COOH), which is one of the main THC metabolites. The threshold amount is 50ng/mL of THC, over which the test will show positive. To make sure that it’s not a false positive, the lab will use a gas chromography/mass spectrometry (GC/MS) test to confirm the results.
Professionally done drug test samples are always split into A and B samples. If you test positive, you can request the lab to test your B sample. If the lab happens to lose your B sample, they will not be able to confirm the positive. By rule, they will have to give you a passing grade.
In theory, people who consume between 1,000 and 2,000mg of hemp oil every day might fail the first urine tests. These are very rare cases and they indicate a false positive if certain non-THC metabolites trigger the immunoassay reaction. However, the following GC/MS test is going to be negative.
When all is said and done, you need to source high-quality hemp oil and stick to the recommended intake. This way it is highly unlikely to fail a drug test.
Hemp oil can be used orally or topically. For topical use, apply a generous amount of oil directly onto the affected area a few times a day.
When it comes to oral use, one or two tablespoons a day are enough to help inflammations, digestion, and heart health. The dosage may vary depending on your age, weight, and exact medical condition.
fail a drug test from hemp oil?
The bottom line is that there is no risk of failing a drug test as long as the hemp oil doesn’t contain any THC or CBD. Even if there are some cannabinoids in the oil, the concentration is far below the amount required for you to test positive.
The important thing is to find a reliable full-spectrum hemp oil and follow the recommended dose. And if you are not sure about the application or dosage, consult your physician.
In general, there is almost no risk of failing a drug test from using hemp oil. Most of these oils don’t contain any cannabinoids
