To tell you the truth, I don't believe that even the most creative anti-smoking advertisement can make you quit smoking after you see it. It's just not how the things work.
When a smoker runs into another anti-smoking ad, often the reaction is - "yes maybe it is cool, but it won't make me quit - it's a waste of time and money". Well of course, one single ad won't change your mind in a second, but it does create the awareness that smoking is a BAD thing, and when a message is being repeated over an over again - it finds its place somewhere deep inside your unconscious mind.
It takes time, but some day it may build up, and it will seem as though as YOU have an idea - "smoking is really a stupid thing to do, I quit!" What may seem as your own idea, could be a huge job of those creative antismoking ads you used to see everywhere.
