YitzchokM, Although I oppose your position on this topic, I agree that in order for a discussion to be intelligent it must be dispassionate.
It is true that Rav Moshe stopped just short of outright prohibiting smoking, however…
This conversation is incomplete without mention of Rav Moshe’s Psak [the same Rav Moshe – this Teshuva is in Choshen Mishpat 2:18] that even if smoking is permitted, the fact that it is damaging, or even bothersome, or simply annoying, to others can not be discounted. He therefore rules that you may not even smoke in your own home if the secondhand smoke will damage, or bother, or even simply annoy, your neighbor.
