For anyone who hasn't read the links in this string yet. It is helpful to understand the dangers of smoking so you can fully appreciate the gift you have given yourself for quitting. The articles in this string give a pretty good overview of smoking induced problems. What should be understood by all is that quitting help reverse most of these problems. With the exception of emphysema, which is the result of destroyed lung tissue which doesn't regenerate, or actual lost heart tissue or brain function from a previous heart attack or stroke, or an amputation that has already occurred, they body repairs itself quite will. The trick was to quit before sustaining such permanent damage. The earlier the better. You can't alter your past smoking, but you can erradicate all future smoking by always remembering to never take another puff!
