Smoking, as stated time and time and time again, is absolutely terrible for one's health, and the slight high/buzz from smoking, which does affect the pleasure sensing portion of the brain, is certainly not good for one's health and not worth the clear health risks associated with smoking.
Okay, I would be lying if I said smokers were not attractive; it just seems so irrational! I have dated a smoker, and as disgusting as it sounds, I acquired a liking to the smoke taste while kissing. Though, I ultimately convinced my now ex, to stop smoking for health reasons since the few pros are 100% dwarfed by the multitude of cons.
With that said, I have never smoke and I never will.
