I have been a heavy smoker for 42 years, two or more packs of cigarettes every day. I have tried to quit numerous times, but could not stay quit and would start back after a few weeks. I had been diagnosed with COPD and my lungs were scarred from numerous bouts with pneumonia. I could not even do my normal household chores without having to stop and rest. A friend of mine suggested I try electronic cigarettes. I was skeptical at first, but decided to do my research. I decided on the type of e cig that allows you to refill the nicotine liquid. I ordered got my supplies and got started. I have not touched or wanted a cigarette since. My breathing ans stamina have improved greatly, blood pressure back to normal, and no cigarette stink. As long as electronic cigarettes are available, I will NEVER touch another tobacco cigarette.
