YOu can't scare someone into quitting. My sister saw me while I was on breathing machines and on my death bed (not from smoking but from ARDS) and she will still not quite even though empesma and chronic bronchatitis runs in my family. I might not have been sick from smoking but it's these machines she could end up on if she doesn't stop. Don't kill yourself trying to save someone else for it's not going to work. You can be supportive and give her reserach on smoking, but that's about all hon.
