In spite of gains that anti-smoking agendas have had, I can't see this draconian measure passing final judicial muster, because of the outdoor-public, within-your-own-car and detached-home-only-residence restrictions - not that many lesser restrictions should also not pass, in my view. But, I think these three will take the idea too far for a majority of jurists.
There are LOTS of outdoor places where smoking is now forbidden and frankly, that's insane.
