Rictor - no offence taken of course

I guess my anti-smoking side is showing through. Several of my friends are.. heavy smokers. Normally this isn't an issue but from time to time I find myself sitting next to or between a couple of them in a pub. It's amongst the most unpleasent things I've ever endured... I leave with a headache and clothes that reek of smoking.
But enough bashing it. That's not the point of the thread.
Perhaps a better notion on the part of companies would be to severly cripple the health insurance of any high-risk catagories such as smokers and other parties that might willingly damage themselves either in body or mind.
Unfortunately - it's very hard to police this. Even smoking itself isn't clear cut... one man might smoke a single ciggarette at a party if the mood takes him, while another might be on a 10+ pack a day habbit and suffer serious mood swings when he's denied smoking.
This grey area has obvious connotations with health insurance.. for instance: does the man who smokes one at a party fall into the same catagory as non-smokers at this same party? They're passively smoking and therefore damage is being done after all...
And of course on top of it all, there is a certain amount of freedom of rights to this. Where does it stop? If I drink regularly at parties (which may eventually affect my liver) am I in the same risk catagory as a smoker? How do you evaluate it?
So of course it's a very grey area.. both in execution and in the way it affects peoples rights. Myself? I'm tainted toward anti-smoking but then I have drunk heavily and/or smoked cannabis before... so who am I to say for certain.
