CBD products can still be problematic, however, when it comes to drug testing. Though drug tests screen for THC, not CBD, many CBD products contain a trace amount of THC which will be detected in your bloodstream during a drug test.
Factors in CBD Oil Showing on Drug Screen
The legality of CBD products can be confusing. CBD products made from certain cannabis plant varieties are legal only in states where marijuana is legal, due to the potential THC content. CBD products made from hemp variety plants are legal throughout the United States as long as they contain less than 0.3% of THC and do not make any medical claims. (A hemp plant is defined as Cannabis sativa that contains less than 0.3% THC.)
Taking CBD If You Undergo Drug Tests
Topical products that claim to contain CBD—like shampoos, cosmetics or creams—should not cause any reaction during a drug test because they do not enter the bloodstream. In the case of CBD oils, gummies, teas or transdermal patches, the situation is more complicated. In a test of 84 CBD products obtained online, 18 contained THC.
Different drug tests have different cut-off levels. Legally, hemp products can contain up to 0.3% of THC.
It’s also worth noting that because CBD products are not regulated by the FDA, it’s possible that you could be taking CBD that is mixed with other cannabinoids, which could increase detectability. Also, it’s worth noting that the more frequently you use cannabis products, the wider detection windows become.
Furthermore, some tests are more effective at detecting THC and for longer periods of time. The type of drug screening you’re administered – and how long after you last took CBD – could influence whether it’s detectable.

Regardless of how you take it though, the effects can typically last between one to three hours.
This can be particularly worrisome if you are searching for jobs or need to consent to drug screenings for other reasons (e.g., being on parole). It’s a common misconception that CBD and THC are the same; while CBD is a natural supplement, it’s still possible for the THC metabolites to be detected during drug screenings.

For many people, making the decision to get help can be the hardest part. But you’ll be happy you did, and the sooner you take action, the better.
Urine tests are the most popular and common method of drug screening for employers. The detection-window for THC through urine tests can vary widely.
A CBD isolate is a pure compound with no other active compounds or cannabinoids. The full-spectrum compounds may include other active chemicals, such as cannabinol and cannabis terpenes (the part of the plant that gives the plant its aroma).

Using Product With THC
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?
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 likely to occur when CBD oil is purchased from cannabis dispensaries in places where cannabis is legal.
Does CBD Oil Contain THC?
CBD oil is usually marketed as THC-free, but that's not always the case. Full-spectrum CBD oils contain other cannabinoids, which may include THC. Isolate products may be contaminated with THC, as well.
