I had smoked on and off for about 8 years, up to a pack a day until about 5 years ago. I have never had issues with the physical effects of smoking (no nicotine withdrawal/etc). For me, it’s the act of smoking that is/was addictive. When I wanted to quit, I simply quit cold turkey and was only tempted to smoke if I were drinking. (alcohol) About 2 years ago, I was somewhat tempted to pick up smoking again because of stress in regards to work. I really didn’t want to start smoking, though, because of the negative health effects and I think it’s a disgusting habit. So I decided to try electronic cigarettes as I knew that it was similar to the act of smoking (which was my real addiction) but I had the option to get nicotine free products, so the health risk was slight to non-existent. I also liked the idea of all the flavors that were available with vaping. I wasn’t smoking for at least 4 years by the time I decided to try vaping so I didn’t have any changes from vaping. I have had no physical side effects or negative effects of using electronic cigarettes. The only thing that may happen is your mouth can get dry because the glycerin in the liquid pulls moisture from your mouth. (you can get dry mouth from cigarettes too, I did) Drinking adequate water eliminates that. When I smoked cigarettes (analogs), I had horrible chest pain, headaches, sore throat and sometimes nausea. I have a very sensitive body, which is why I smoked smoking. It simply hurt too much. I also didn’t like the way it made me smell. I was rolling my own in the end, so cost wasn’t too much of a factor. Overall, my experience with vaping is highly positive. I have tried nicotine e-liquid a couple times, just to see what it’s like and I don’t like it. It has a strange taste to me and I figure if I’m not addicted to it, why start back up again?
