Products made with hemp seeds have varying concentrations of cannabinoids, and their ingestion can lead to positive results on urine tests in the workplace and emergency department. Most drug tests detect THC, the psychoactive component of marijuana, which can be detected in a test for a few days after single use or for a month with heavy marijuana smokers. Drug tests don't detect CBD because it doesn't cause intoxication and isn't an illegal controlled substance. However, people who use CBD may not pass a drug test due to contamination with THC or incorrect labeling.
A routine drug test won't detect CBD, so using hemp oil or other related products won't result in a positive drug test. The CBD industry is not strictly regulated in the United States and there is a large gray market in Canada. This means that it's possible to fail a drug test with a CBD product. While these tests don't detect CBD, some products contain low amounts of THC that could theoretically cause someone to fail a drug test.
Additionally, researchers have found that 21% of online CBD and hemp products were mislabeled. The presence of delta9-tetrahydrocannabinol (THC) in these foods has raised concerns about its impact on drug test results for marijuana in the workplace. CBD itself may not cause a positive effect on a drug test or give a positive result, but products that contain higher amounts of THC than the manufacturer claims can cause someone to fail a drug test. CBD-rich products are derived from cannabis or hemp, which contain the full spectrum of cannabinoids, including THC.
Urine drug tests that detect the presence of marijuana look for a single metabolite of THC that is separated from CBD. Drug testing is used to detect the presence of one or more drugs in someone's urine, blood, saliva, hair, or sweat. A study evaluated the impact of prolonged daily intake of THC through hemp oil on the urine levels of its metabolite 11-nor-9-carboxydelta9-tetrahydrocannabinol (THC-COOH) in four different daily doses of THC. The researchers concluded that using hemp-derived products doesn't always guarantee passing a drug test.
According to the Center for Disease Control (CDC), 16% of car accidents are drug-related, with marijuana use being the second most common. The subjects self-administered THC in 15 ml aliquots (20 ml for the 0.6 mg dose) of four different blends of hemp and canola oils. Despite its high popularity, there is still confusion about cannabidiol (CBD) and whether it will appear on a drug test. In many states in the US, CBD oil is legal but is regulated by the Food and Drug Administration (FDA).
