Very small amounts of THC present in the material from which CBD is extracted can enter CBD oil in quantities high enough to test positive 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, as opposed to an online retailer. The researchers found that CBD, or cannabidiol, did not react with either of the two commercial tests used to detect marijuana use. However, another cannabis compound, cannabinol (CBN), did.
Drug tests do not detect CBD because it does not cause intoxicating effects and is not an illegal controlled substance. However, people who use CBD can fail a drug test. Products containing CBD may be contaminated with THC or have incorrect labelling. 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 abide by the guidelines set by the Substance Abuse and Mental Health Services (SAMHSA), which include screening for THC but not CBD. In addition, Spindle points out that "it doesn't take a lot of THC exposure for some people to test positive. In theory, getting a false positive drug test from CBD oil should be relatively impossible from a pure CBD oil containing less than THC.
However, someone using CBD oil containing residual THC could test positive on a urine drug test, not because of the CBD itself, but because of THC contaminants in the oil. Reports are surfacing across the country of famous sports players, corporate employees and others testing positive for THC - the psychoactive component of marijuana - even though CBD oil is said to contain no THC. Since there is no guarantee that the use of CBD oil will not result in a positive result in workplace drug tests, its use should be questioned at this time. No positive urine drug test results were observed in the other testing sessions (pure CBD capsules, pure CBD vape or placebo).
Read on to find out how to avoid a positive drug test result, what to look for in CBD products and more. These results suggest that pure CBD, consumed once by itself, will not cause a positive drug test result, says Vandrey. Some sources report that, on rare occasions, false test results have come from CBD oil breaking down into very small amounts of THC in the stomach. While the risk of a positive test may be low, as a result of this possibility, CBD oil may not be suitable as a pain management strategy for LIUNA members.
In addition, Spindle points out that it does not take a large exposure to THC to test positive in some people. Although hemp-derived CBD products are available in states where recreational cannabis is not legal, some people may be concerned about whether their CBD oil use will show up on a drug test.
