I have smoked since the age of 16. At least 25 years of my life as a pack a day smoker. I have tried the patch, gum, pills etc. and they helped with the cravings but I always went back to cigs. I did quit twice in my life, once when I was pregnant and the other time I got really sick and couldn’t smoke. Both times I quit cold turkey. The first time, I quit for about a year and a half, and the second time for 5 whole years. When starting smoking after being a quitter for 5 years it was stress related. I kept telling myself I was going to quit ( on Monday). That went on for 2 years. I started seeing these electronic cigs an vaporizers more and more often, and talked to people who had success with them, so I decided to give it a try. That was all she wrote. I almost seamlessly transitioned from analog cigs to a vaporizer type e cig. I use a battery and clear tank that you fill with e liquid. I actually, like many smokers enjoy smoking. However you can’t exactly enjoy the idea of cancer, emphysema etc.. Each time you exhale, not to mention how disgusting cigarettes smell. I know that the studies of health effects from e cigs are still pretty new. But so far there hasn’t been any serious negative reports. I think it was a great trade off. I love my vaporizer, I don’t really care about the nicotine level so much. I started out at 16mg about 8 months ago which helped me get off the cigs. Now I am at 6 mg and I’m perfectly fine with it and expect to be nicotine free within the next few months. I know at least 4 other people that were heavy smokers that have started vaping and were able to quit smoking right away. Anyway I absolutely love it. I still get the satisfaction of smoking with out the smell, the tar and other nasty chemicals and I feel good. I highly recommend it as a smoking alternative.
