I’m 72 and smoked for over 50 years. I have COPD and was told by the doctor I had to quit smoking. I tried patches and then Nicotine Gum but they were only temporary fixes and I always started smoking again. Three and a half years ago I bought an E-cig kit online and quit smoking immediately. I smoked three cigarettes in the first few months but none since. My doctor was very impressed at how well I can breathe now and I seldom ever use my inhaler. I know I will never return to smoking and have cut down on my nicotine level.
