Will I fail a drug test if I use hemp/CBD Oil?
Although unlikely, it is possible that someone could fail a drug screen when using these products. Drug tests look for elevated levels of the intoxicating molecule, THC. The drug test identifies if a THC level is above a particular threshold. If so, it’s considered positive. Theoretically, you could use enough hemp extract and therefore consume enough THC to truly surpass that threshold and trigger a true positive…but it would be pretty difficult, and expensive.
Also, there is no “magic dose” of CBD oil / hemp extract that you can use and ensure you stay below the THC threshold in a drug screen. Metabolism of THC is highly individualized and depends on many variables, including body composition, activity level, dose, duration of use, etc.
However; what’s more likely is that hemp extract can trigger a false-positive. This is because the most commonly used drug tests, urine and saliva immunoassay tests, are so common because they are quick, cheap, and easy. But unfortunately, they aren’t very specific. That means they can confuse one molecule for another, especially when they look alike. This can happen with CBD and THC, which would trigger a FALSE positive.
