I smoked cigarettes for for over 40 years before trying an e-cig. My first were the type were the not very effective cigarette sized models. Then when I got my first Ego style battery, it got a lot better and I could skip my morning real smoke. Now I am using a tank system that has nearly gotten me off the ‘stinkies’ completely, most days 1 or 2, others none. I was a pack a day smoker(or more) and had a bad smokers hack Now I feel much better, and can breath deeply. I would highly recommend anyone who smokes to give these a try, they will change your life for the better.
