27 years of 1-2 packs a day and quit in Feb. 2008. In Oct. 2009 the smokers cough came back and wouldn't go away. After different tests they diagnosed me with stage 3 emphysema. Spend one day where any physical activity, or sometimes none at all causes uncontrollable coughing and shortness of breath. Where on a good day you can walk at a slow pace for more than a 100 feet without stopping to breathe and then tell me again how much you enjoy smoking. It wasn't going to happen to me either, just the other guy. And for those on the ecigs, do some indepth research on them as to the safety.
