The first step to stop smoking is to want to stop more than you want to continue...a lot more. Until they get to that point, nothing can or will change. Willpower plays a key role in breaking any habit, and nicotine addiction is a most powerful habit. You can make breaking this addiction less painful though. I quit about 15 years ago. My method was gradual, nearly painless, as far as withdrawal goes, but very inconvenient (in that lies its strength). It requires you to go out of your way, take the longer tiresome route, and be more stubborn than the habit. Basically it involves using an Amerindian herbal tobacco called 'kinnikinnik' to gradually taper off real tobacco. As said, its very inconvenient, so until they are highly motivated to quit, this method will not work for them...no method will work for them, and there is nothing anyone can do to make them want to quit.
