DO you think you can easily stop your habit of smoking?

I am not a smoker but I bvelieve you can stop it. It is not easy to quit smoking. I also not sure this few method work or not, I just heard from a friend of my boy friend. He smoke for around 6 years but he have quit it recently. These are thetips that he told me. 1) get ready some sweet in your pocket, eat it when you few like want to smoke. There are some antismoke sweet is better. 2) Always do exercise 3) Find something to do and don't let yourself too free. This will let you forgot to smoke.
