whats the best way to stop smoking ?

Well friend i think that the best way is to control yourself from it and also say your mind that it is bad and you are good and i think if you smoke if is really bad for you and also for your health and you may be near to someone and that someone needs you and don't let your life go atleast for them.So by thinking this i think you may leave it but i know it is very very tough to do it but you must do it for that SOMEONE.
