Nope: Not directly, no ... But that's not a reason to avoid the discussion with your doctor about drug use. It's important that you give your physician all of the facts ... So that we all can help you in the best way possible. Hope that helps!

No: If they do not ask for that specific test, it will not be run. Also, in most states, you must pre-authorize a drug screening.
