Short answer: No.
Long answer: Because there are many companies out there in the CBD industry, there are many different standards of production. With higher quality brands that do extensive testing and formulating, you may be more confident that there will be no THC present. However, in other brands that have different methods of production, you might have to be more careful whether or not THC could be present.
CBD itself will not inhibit a drug test because CBD isn’t a psychoactive drug like marijuana is (which is filled with THC). There is always a chance that a brand could have trace amounts of THC in their CBD products, so it’s important to research and find out as much as you can about how their products are made and what steps they take to ensure a more THC-free result.
