Well, I don't smoke and never have, but I have a contrary streak (yes, I know that's a shock) and had to reply to this...
I can't imagine deliberately doing something that can out and out kill me. To each his own, but keep it away from me!
...because there are few things out there that *can't* kill you

Driving a car (as opposed to staying home) greatly increases your risk of getting into an accident. Heck, you could drown or be electrocuted while taking a bath... I look at it as a cost benefit analysis -- looking at the risks and deciding if it's worth it to you.
Now, I'm not gonna argue that smoking is healthy <g> but I do think the dangers are somewhat over-emphasized. And that people (adults, anyway) have the right to decide for themselves whether or not to risk it.
