Cannabidiol ( CBD ) should not show up in a drug test. However, many CBD products contain traces of delta-9-tetrahydrocannabinol ( THC ), the main active ingredient in marijuana. If there is enough THC, it will show up in a drug test. This means that, on rare occasions, CBD use can result in a positive drug test. Very small amounts of THC present in the material from which CBD is extracted can enter CBD oil in high enough quantities to give a positive result in a drug test.
This scenario may be more likely to occur when CBD oil is purchased from cannabis dispensaries in places where cannabis is legal, rather than from an online retailer. In most cases, CBD oil is very unlikely to show up in a drug test. Most employment drug tests specifically look for the presence of THC or THC metabolites. Most employers follow the guidelines set by the Substance Abuse and Mental Health Services (SAMHSA), which include screening for THC but not CBD. However, it is highly likely that someone using a CBD oil containing residual THC could test positive on a urine drug test, not because of the CBD itself, but because of THC contaminants present in the oil.
Furthermore, if a CBD product contains THC at a sufficiently high concentration (0. In theory, getting a false positive drug test with CBD oil should be relatively impossible with a pure CBD oil containing less than. News stories are emerging across the country involving famous sports players, corporate employees and others who have tested positive for THC - the psychoactive component of marijuana - despite the fact that CBD oil is said to contain no THC. Hemp-based CBD oils, when used in low doses, are unlikely to test positive because they do not usually contain high enough levels of THC to be detected. However, there have been cases where CBD oil users have failed a drug test due to positive THC results.
As a result of different dosage recommendations and uncertain THC levels, CBD oil consumption carries the risk of a non-negative test result. The first thing to do when an employee claims that a failed drug test is solely due to CBD consumption is to confirm the screening test result using a more sensitive method such as GC-MS or RP-HPLC. Some sources report that, on rare occasions, false test results are due to CBD oil being broken down into very small amounts of THC in the stomach. One study showed that certain laboratory tests can produce identical positive results for THC and CBD.
