Drug tests are designed to detect the presence of certain substances in the body, such as THC, the psychoactive component of marijuana. Unfortunately, the immunoassay used in drug tests can also detect other cannabinoids, such as those found in hemp products, which can lead to a false positive result. Most tests don't measure CBD, so using hemp oil or other related products won't test positive for drugs. However, it is possible to fail a drug test with a CBD product if it is not properly labeled or if it contains trace amounts of THC.
To avoid this, consumers should look for a broad-spectrum or multi-spectrum hemp product rather than a full-spectrum product that may contain THC. These types of hemp products are generally treated to ensure that their final product does not contain THC. In addition, it is important to be aware of the potential for inadvertent exposure to marijuana through second-hand smoke. When choosing a hemp supplement, it is important to look for one that has been proven to be completely THC-free.
It is also important to inform your healthcare professional about any dietary supplements you are taking. By taking these precautions, you can ensure that you won't fail a drug test due to THC-contaminated CBD oil.
