Everyone has their own way of quitting. You got to be mad enough at it to hate it. Then attack it with all you have. I would advise not to use chew though. It's maybe better than inhaling, but still gross and can still give you cancer of the mouth.
Stay away from places that encourage smoking, like smoky bars, and friends who smoke. It's so much easier to cheat in those instances, and once you start cheating, it's easy to start back up again.
My dad and his wife and some friends started rolling their own when the price got high enough. I thought, why not just quit? They had wanted to before.
Now he's passed away (heart attack at 58) and she has gone through a very serious cancer period (stage 4 but has managed to get rid of it) and still smokes. At one point there was no reason for her to quit, because she was dying anyway. Now she still smokes probably because she believes her cancer cure will keep it at bay. Quitting will keep it at bay even better, thinks I.
I smoked a bit in high school, but never got hooked, and frankly can't understand it. I can only wish you luck on your goal to quit. I've seen how hard it can be, but also how wonderful you can feel when you do quit.
