|show her pictures of a decayed lung due to smoking.
show her how much money she would save if shes not smoking. smokes arent cheap.
get your doctor to explain to her how smoking is bad for her condition.
..i dont see how withdrawing her aid for college would make her stop smoking...she could just find different ways in paying for school and continue to smoke.
explain to her that smoking is not something thats healthy, it can lead to lung cancer, heart problems, make her unactive, make your skin look like leather, and make you age faster which is not pretty at all. leaves your hair smelling like crap and your clothes smelling the same way.
i know its not much, but it could help..
