CBD can affect a drug test. Some drug tests can have a false positive simply from a small percent of the cannabidiol compounds in your body.  A few people have failed drug tests due to THC being in the CBD oil that they used.


The CBD oil drug test results can show up positively, which can cause a problem for you. Many times, however, CBD oil failed drug tests are not 100% factual.

The test can be affected in a positive way, however. CBD oil can show a false positive result as well.  Being aware of what the test result has concluded is always a good idea, especially if there is not a chance that you have failed your drug screen.

Certain occupations have a specific test limit for the THC levels.  If there is less than 50 ng/ml, one can pass a drug test. If someone fails their drug test, there is a way to get another result.

There is a blood test that will check for 15mg/ml. If you failed your drug test, try another option to retake. THC can stay in the body for 30 days, and CBD oil can cause metabolism to slow down in your body. If you or someone you know is concerned, try speaking to your employer.

If you have any other concerns as far as CBD oil on your drug screen showing up positive, do your research, check your CBD oil branding for percentages of THC that may appear in your urine test. Also, request a blood screen instead, may be a good option.

The best option for those who are taking a drug test in the near future for someone is to refrain from using anything until after you have your drug screen. It’s much better to be safe than sorry, right?
