As someone who used to smoke and yes was quite addicted to it let me say it IS a choice. I tried to quit several times but what really did it was getting pregnant and NEVER EVER wanting to have my daughter see me smoking. I had smoked for fifteen years and had a two pack a day habit. It's been over five years now and I've never had another cigarette because everytime I get tempted I picture my daughter. Sorry to say, yes I DO still think about it, but it gets less as time goes on. So I did make a conscious decision to quit which implies I was making a conscious decision to smoke. .
