I'm sorry that you have this problem. When I hear things like this I am always lucky to have a family that doesn't smoke. I feel bad for you and for your mom that its so hard to break away from smoking. It's definatley something that is one of the hardest things for someone to get away from.

I would think that the guilt trip might work if you keep going at it, and start showing her all the things that cigarettes do to your body. Tell her you want her to be around when you are older and have kids.

But I don't know what else you could do, I will pray for your mom that someday she can beat her addiction!
