I would love to quit. I started as a child sneaking them from my parents. It was much more prevalent back then. It has hindered me through my life, especially when I was involved in martial arts. Out here in Az, one must be extra careful too as everything is so dry a fire could happen if you don't dispose of it properly.
About six years ago I finally quit smoking inside. Not sure how much that will help me in the long run, but non smokers find it more agreeable now.
