With the increasing availability and widespread use of CBD containing products in the UK, this question regading CBD and drug test results is coming up more frequently.
What’s the difference between CBD and THC?
The primary difference between CBD (cannabidiol) and THC (tetrahydrocannabinol) lies in their effects on the body and brain, as well as their legal status.
CBD (cannabidiol) and THC (tetrahydrocannabinol) are both cannabinoids found in cannabis, but they differ significantly in their effects and legal status. THC is psychoactive, producing the "high" associated with marijuana, while CBD is non-psychoactive and doesn’t cause intoxication. THC is often used recreationally while CBD is linked to reducing anxiety, inflammation, and seizures. THC is illegal in many countries including the UK, while CBD is widely legal in many places including the UK. Although they are both derived from a common source, and have similarities, they interact with the human body and brain differently.
CBD and THC on drugs tests
CBD (cannabidiol) itself typically does not show up as THC (tetrahydrocannabinol) on a drug test, but there are important considerations to keep in mind:
- CBD products may contain trace amounts of THC: Many CBD products, especially full-spectrum CBD, can contain trace amounts of THC. If enough THC accumulates in the body, it could trigger a positive result on a drug test.
- Quality of CBD products: Some CBD products may be inaccurately labeled, leading to higher-than-expected THC content. Poorly regulated CBD products might contain more THC than advertised, increasing the likelihood of a positive drug test result for THC.
What are the most common types of drug tests that detect THC?
The most common types of drug tests that detect THC are urine and saliva tests. Urine tests are the most widely used, as they can detect THC for between 3-4 days and up to 30 days in some users. Saliva drug tests detect THC within 8-12 hours after use and are often used in roadside or workplace drug screenings. Hair drug tests can also detect THC but are less often used as they are more costly. Hair tests have the longest detection window, sometimes detecting THC up to 90 days after use, but are less frequently used.
Does CBD itself show up on drug tests?
CBD (cannabidiol) itself typically does not show up on standard drug tests in the UK, as most drug tests are designed to detect THC (tetrahydrocannabinol), the psychoactive compound in cannabis. However, there are a few factors to consider:
- Trace THC in CBD products: Many CBD products, especially full-spectrum CBD, may contain small amounts of THC. If you use these products frequently or in large doses, the THC may accumulate in your body and show up on a drug test.
- Mislabeling of CBD products: Some CBD products may contain more THC than advertised, which could increase the likelihood of a positive drug test result for THC.
To avoid issues, you can use THC-free products, such as CBD isolate, or ensure the CBD you use is third-party tested and labeled as containing no THC.
Are there any drug tests that detect CBD?
There are several drug test products from UK Drug Testing including a vape drug test kit which are designed to screen for various substances, including CBD. It features a simple, easy-to-use design and allows for quick testing, which can be helpful for employers or individuals wanting to monitor substance use. The kit is specifically tailored for those who vape, aiming to identify any relevant substances in the user's system.

How long does CBD stay in a persons system for a drug test?
CBD can stay in a persons system for several days to about a week, but it depends on various factors, such as the dosage being taken, frequency of use, metabolism, and body fat. Typically, CBD may be detectable in urine for up to 5 days, but for frequent or heavy users, it can stay longer. However, most standard drug tests currently don’t screen for CBD specifically, only for THC. If you’re using CBD products that contain trace amounts of THC, it’s the THC that could potentially show up on the drug test.
How sensitive are drug tests to THC?
Drug tests are generally very sensitive to THC and can detect it at varying thresholds depending on the sensitivity of the drug test used. For urine tests, the standard cut-off level is usually around 50 ng/mL for initial screening although newer ultra sensitive THC urine drug tests can now detect levels as low as 20ng/ml , with confirmatory lab drug tests often set at low as 5 ng/mL.

If you're concerned about THC appearing on a drug test, using CBD isolate (which contains no THC) or third-party tested products labeled as THC-free may reduce the risk.
