Quit Smoking Campaigns Posters

I am designing an anti-smoking campaign for my school, what are the innovative strategies that I could use to win
interest students? My target audience is between 18 to 24 years. What could I do to educate them about the risks of smoking and encourage them to quit smoking? So far, I have thought about placing posters around the school and the start of a Healthy Living Club which acts as a support system. Have you any ideas? If you are / were a smoker would help you quit smoking?
Because of the age your target audience, I would try to link it to sexual performance and reproduction. Not Guy wants to hear about erectile dysfunction and sperm damage; no girl wants to hear about smoker's breath and babies with low birth weight. I'm sure if you search you will find some data show that smoking is injurious to sexuality.
