I quit smoking two months ago today, and i smoked a pack a day since i was 15, and i am currently 21 years old. Vaping electronic cigarettes have helped me dramatically with everything smoking related. I feel healthier, i can run, i can do everything a lot better and easier than when i was smoking cigarettes. If it werent for electronic cigarettes, i would be sicker than ever and still in bad shape. this is a huge improvement in my life. i am so thankful i found electronic cigarettes.
