It looks like Florida has come up with a law that prohibits doctors from prescribing on the basis of a questionnaire alone.

If you look at #3 in the above article, there is a provision for emergency doctor-patient relationships. I have no idea how that's going to be applied in practice, though. I sure hope the Florida OP's can adapt!
