I'm personally very against smoking. For ME. I don't care what you do. What DOES bother me is when smokers want special treatment. When people seriously ask if they will get extra work breaks because they're smokers, that's not fighting descrimination, that's expecting a reward. You're right: it's YOUR choice, and you should live with ALL of the consequences, even the ones that affect you in the present.
Sincerely, A Breather.
