Happydriver, smoking on GA flight deck has now moved to "by unanimous consent" of both pilots. There are captains who refused to allow the F/O to smoke, and F/Os who refused to allow the captains to smoke. Throw the PIC is GOD mentality out of the window, those types are no longer welcomed here. No "dirty tricks" on the non-smoking F/O by the captain for insisting to smoke.
