You seem to make a big deal about smoking? If it's really not a big deal to you then why make it so? My mom and step dad smoked for many years - my mom had to stop after she had her heart attack and my step dad finally got around to quitting after like a zillion years. I'm apathetic about you smoking, your making a thread making me actual post about it.
Do you have people who pressure you to stop smoking? Maybe no one actually cares about YOU quitting, maybe they care about the people quitting who don't know better and would quit if they did. Maybe they care about the people who might want to quit so they don't raise their kids in smoke, who might want to quit for many reasons.
Look at the anti smoking ads that way and stop complaining about them.
