Will Cannabidiol (CBD) result in a positive test for marijuana?

CBS is typically used for medical purposes and is one of the components found in cannabis. It is not regulated by the Federal Drug Administration. Pure CBD does not cause positive test results, however, many products which contain CBD may be contaminated by tetrahydrocannabinol (THC)  which could lead to variable results. Another cannabis compound is cannabinol (CBN) and is a THC variant so if this is in the cannabis used, it may also yield a positive test result.
