Cannabidiol (CBD) products are becoming increasingly popular for their potential wellness benefits. At the same time, workplace drug testing is more common than ever, raising an important question: Does CBD show up on a drug test?
Most standard drug tests are designed to detect tetrahydrocannabinol (THC)-the psychoactive compound in cannabis-not pure CBD. However, some CBD products may contain trace amounts of THC, which can trigger a positive or lead to a positive result on certain tests. Even minor inconsistencies in labeling or extraction can affect test results or cause a failed drug test unexpectedly.
In this blog, we’ll explore how CBD interacts with drug testing, the effects of CBD, and how THC metabolites are detected in urine samples. You’ll also learn what to look for in trustworthy hemp plant products and how to avoid potential risks linked to non–FDA-approved CBD formulas.
Understanding CBD and THC
To understand how CBD may affect a drug test, it helps to know what these tests are looking for. Most drug tests are designed to detect drug misuse, which can pose risks to both individuals and workplaces. Employers use these tests to maintain safety and compliance.
CBD enters this discussion because it’s extracted from the cannabis sativa hemp plant, which naturally produces both cannabidiol (CBD) and tetrahydrocannabinol (THC). While these two cannabinoids share a botanical origin, their effects on the body differ dramatically.
THC produces psychoactive effects-the “high” associated with marijuana-whereas CBD is non-psychoactive and doesn’t impair clarity or coordination. Understanding this distinction is key, especially since some CBD oils may contain trace amounts of THC that could trigger a positive drug test depending on sensitivity and use.
The Difference Between CBD and THC
Differentiating between CBD and THC is essential when it comes to drug screening outcomes. Both compounds interact with the body’s endocannabinoid system (ECS), but they do so in distinct ways.
Delta-9-tetrahydrocannabinol (THC) binds directly to CB1 receptors in the brain, producing euphoric or psychoactive effects. Cannabidiol (CBD), however, interacts more indirectly, supporting balance and relaxation without altering perception.
Because THC metabolizes into compounds that remain detectable for weeks, THC metabolites in urine samples can persist for 30 days or longer, depending on metabolism and frequency of use. By contrast, CBD’s byproducts generally clear faster and are not what most labs target.
Still, non–FDA-approved or mislabeled products that are not true CBD isolates may contain trace amounts of THC, which can lead to a positive test result-especially after high doses or prolonged use.
CBD and Drug Testing
Even though CBD itself isn't usually what drug tests look for, using CBD products can sometimes lead to a positive result. This is because some CBD products, while the legality of CBD requires them to have less than 0.3% THC (the part of marijuana that gets you high), might be mislabeled or contain more THC than advertised due to the unregulated nature of the CBD industry.
Regular, high-dose use of CBD also increases the risk of testing positive for THC. Therefore, people using CBD should be cautious and informed about the products they choose to avoid unexpected test results.
Only orally taken CBD products will appear on a drug test. Does CBD or hemp creams show on a drug test? CBD creams and other topicals will not appear on a drug test unless the cream or topical is transdermal and contains THC. So, using CBD products that you have to digest will put you at more risk for drug test failure than a CBD topical would.
Types of Drug Tests
When it comes to detecting cannabis or hemp plant compounds, not all drug tests work the same way. Different methods are used to identify THC metabolites—the chemical traces that remain in your system after using products that contain even trace amounts of THC.
Understanding the types of drug tests is important for anyone who uses CBD, especially if you’re concerned about whether it could trigger a positive result. Below are the most common testing methods used for detecting THC and related substances:
Urine Test
Urine testing is the most common method used to detect cannabis use. These tests identify THC metabolites-the chemical byproducts your body produces after breaking down THC. When a person uses a cannabis product containing even trace amounts of THC, those metabolites can remain in urine samples for days or even weeks.
CBD itself typically does not appear on a standard urine test, but contaminated or mislabeled products may still trigger a positive result. This can happen when non–FDA-approved products contain more THC than the label indicates or when users consume high doses of full-spectrum CBD over time.
The effects of CBD aren’t what these tests are looking for-the focus is solely on detecting THC and its byproducts. However, consistent users should be aware that repeated exposure to even small amounts of THC may build up in the body and lead to a failed drug test.
Blood Test
Blood tests offer precise detection of recent cannabis use by analyzing THC and its metabolites directly in the bloodstream, which the liver processes soon after consumption. A blood sample, taken and lab-tested, can reveal cannabis use within hours to days, depending on usage levels. Although more invasive than urine tests, blood tests provide a more accurate measurement of current cannabis presence.
Saliva Test
Saliva tests quickly reveal recent cannabis use by detecting THC absorbed into the bloodstream and present in saliva. A swab collects the saliva sample, which is then analyzed, offering a non-invasive and rapid way to identify cannabis use within a few hours to a few days.
However, unlike urine or blood tests, saliva tests have a shorter detection window, making them more effective for identifying very recent use.
Hair Follicle Test
Hair follicle tests detect THC and its metabolites deposited in hair follicles via the bloodstream after cannabis use. These substances embed in hair shafts as hair grows, forming a historical record of drug use.
In the test, a small sample, usually from the back of the head, is sent to a lab. The sample, representing the most recent 1.5 inches of growth, allows detection of drug use for up to 90 days or more, offering a historical view less affected by occasional or one-time use than other tests.
Does CBD Show Up On A 10-Panel Drug Screen?
The short answer is it depends. The standard 10-panel drug screen test for the following: Amphetamines, Cocaine, Marijuana (THC), Opiates, Phencyclidine (PCP), Barbiturates, Benzodiazepines, Methadone, Propoxyphene, Oxycodone, and more illegal drugs.
Understanding what type of CBD product you are taking is an easy way to know if it will show up on a drug screen. If you are talking Full Spectrum CBD, which contains THC, then yes, you will test positive. Whereas if you take Isolate or Broad Spectrum CBD that is THC-free, then you shouldn't test positive.
Will CBD Show On A Military Drug Test
The military mainly uses urine tests to check for drug use, and these tests are very thorough. They look for a wide range of illegal drugs and even some prescription medicines. The military has a strict rule against using CBD products.
This is because even small amounts of THC can cause a positive drug test, and the military wants to make sure everyone is ready and able to do their job without any risks from drug use. So, even though CBD might be legal in some places, military members are not allowed to use it.
A failed drug test for minor illicit drugs could mean rank reduction, loss of pay, or non-judicial punishment. For "hard drugs," a service member might face a court-martial, dishonorable discharge, or even confinement.
Understanding CBD Drug Tests Results
Understanding CBD drug test results requires knowledge of the testing methods, cutoff levels, and potential for false positives or negatives. Drug tests have specific thresholds, known as cutoff levels, which determine whether a substance is detected.
Regarding CBD, the focus is usually on THC detection rather than CBD itself. False positives can occur if a CBD product contains higher levels of THC than claimed or if there is cross-reactivity with other substances. On the other hand, false negatives can happen if the cutoff levels are set too high or if the testing method used has limited sensitivity.
It is essential to interpret drug test results cautiously, considering factors like the specific test administered, individual metabolism, product quality, and usage patterns. Confirmatory testing or consulting with a healthcare professional can provide further clarity if there are any concerns or discrepancies in the results.
Sum It Up!
In conclusion, navigating CBD and drug testing can be a complex and nuanced process. While CBD may not always be the primary focus of drug tests, it's crucial to understand the potential risks and factors that can affect the results. Consider the legality and THC content of CBD products, as well as the different types of drug tests commonly administered, such as urine, blood, saliva, and hair follicle tests.

Hi Monica, concerning your other question. There are no known side effects of taking too much CBD. From what studies we have found, as long as there is no THC in the CBD oil your taking, you can’t overdose on it. However, if you take too much CBD, your body may not be able to use all of it, and it could go to waste.
Hi Linda, nano CBD is a good option because the CBD is broken down into smaller particles to be more easily absorbed. However, nano CBD is preferred for products you must digest. If you take an oil like our Broad Spectrum CBD, you place the oil under your tongue and hold it there for 30-60 seconds. This method with this type of CBD oil is just as effective.
Is CBD bad for you if you take too much?
I have MS. Research says nano form would be more easily absorbed. Use 500 mg full spectrum CBD now
