How do I get my friend to quit smoking?
One of my best friends is 19. I am 18 and I can't say I've never smoked before, because I have with her. She has been smoking for about a year and she smokes about 3 cigarettes a day. I tell her to quit, and she tried it, but said she NEEDED one after "quitting" for 3 days. How do i get her to realize it is bad for her and that she needs to stop?
you can't, she has to want to quit to be able to have a chance at succeeding. Telling her to quit, telling her about the chemicals in them, showing her pictures of cancerous lungs will not help. She is already addicted, it is too late for an easy quit. At least she is only smoking 3 cigarettes a day, it could be much worse (and probably will be in the future).

I am an ex-smoker who didn't quit or should I say COULD NOT quit until I made my mind up to do it for me (doing it for someone else doesn't work, she has to want to do it).
