I was a smoker for 11-12years. I started vaping in November of 2012. I use a standard electronic cigarette battery with a 900MAH. I started off with a 24 nicotine level I brought my self way down to 18 then 12 and now I am on a 6 nicotine level. I honestly tried to smoke a traditional cigarette because my battery went dead and didn’t have an extra one this was 3 months after not having one and it made me ill with headache and got sick from traditional cigarette but vaping is worse from what some people say don’t understand that one. I walked out of electronic cigarette shop quitting cold turkey which I tried without the vape pen never could this without my vape pen. I tried quitting traditional cigarettes 4 times cold turkey (do not do pills) this worked for only a few months before returning to traditional cigarettes. I currently have been without a traditional cigarette for a year and a half I feel great. Health wise this is a great decision I had chronic bronchitis, raspy voice, chronic sinus infection have not had 1 since vaping normally I had each 2-3 times per year obviously vaping works. I also got my sense of smell and taste back within months of starting vaping. It is way better for environment as well you can recycle a vape pen but can you a cigarette butt?people need to do research before deciding anything you’d be shocked how this changes your life for the better.
