It's true. I'd take up smoking again just to blow a little at you (I'm not trolling here). I feel quite strongly about the whiney ****y self righteous sanctimonious better than thou attitude displayed by a lot of people in this thread, and to a lesser (lacking balls) extent, the irl anti-smoking brigade.
I've personally felt the negative health effects of smoking, in a fairly serious sense. So I choose not to smoke. But I still defend the right of a person to smoke, and I can still understand why a person might smoke. In the same way that I can understand why a person might stick a needle in their arm, or eat junk food or drink a little too much on Friday night, or work out too hard or take a risk crossing a road to catch a bus blahblah.
My stance is thus; if I don't want to be around smokers, I move away. If I don't want to smell, or smell of smoke, I move away. It's really that simple.
Catch a grip duders!.
