I have smoked cigarettes on and off (mostly on) for 33 years. one would think being diaganosed w/t COPD a couple years ago would be incintive enough to quit, it was not. I could not quit despite all I know about the health implications. I felt those cigaretts killing me. I felt every cigarette drain my energy, make me feel like shit, make me cough and stink up my new Corvette. My husband brought me the Joyetech electronic cigarette. I have not touched a traditional cigarette since. I also have stopped hacking up a lung in the morning when I wake up. my constant cough has gone away, I have a little more energy every day. I am looking foward to getting on with my tobacco free life. Vape on!
