NOTE: I really don't want this to come across as putting anyone down.
I use to smoke for about 3 years. I quit when I met Dave and became a CNA. I quit for several reasons:
1) my own health, Dave's mother died of cancer just before I met him. She was a heavy smoker and only in her 40's. I don't want MY children to have to go through that.
2) I couldn't stand that smell on my clothes when I was taking CNA classes and bending over a bed to work on a patient.
3) I didn't want to be a hypocrite when I started nursing school or became licensed. I didn't want to have to tell my patients they shouldn't smoke, that they needed to quit and then turn around and go puff one myself. Lead by example!
