it's cool if you don't like smoking. just accept that other people happen to like it, and trying to force your opinion upon all these is nothing less but attempted totalitarianism.
and, sorry for your loss, but losing someone close is painful, regardless of what killed him or her. my own father died from throat cancer at 76, likely from smoking 4 packs pall mall with no filter a day for 60 years. so, did tobacco kill him? no. his stupid behaviour killed him.
you see, tobacco, for all i know, was first used by indians on a very social basis, like, when they came home after a long day of, uhm, whatever they did, they'd like sit at the fire and pass around a pipe.
white people copied the habit, then reduced the social and smoked their pipes alone, later reduced the pipes and rolled the tobacco to cigars so that they could have more, and faster, and yet later, made it into cigarettes that they could have yet even more, faster and more often, ending up smoking several packs a day at their desks and dropping dead from lung cancer.
did tobacco kill them? no. their stupid behaviour killed them. or if you want, our society's sick and insane ever more, always faster etc etc. killed them.
would we come home after a day of whatever and pass around a pipe, health effects would be zero point zero.
i know what you're thinking. but think about what i said a sec instead, really.
and one last little something to all you fitness and health fetishists out there: you might not necessarily comprehend this (if you would, you'd not take that stance), but there's things beyond that....
