Apart from the smelly breath and clothes, just remember that person will never have any money, they will get yellow teeth ,develop a cough, and age prematurely , and people avoid you like the plague (even if you do not realise it )
Reformed smoker myself,don't think i could go out with a smoker ever again,the smell and everything surrounding the filthy,stinking,life taking habit is just wrong.
Yes i would, wouldnt stop me in the slightest.. all the anti smoking facists make me chuckle..
