I had been smoking for ten years and atleast one pack a day. I would smoke on weekends up to two packs. I had some friends who turned me on to vaping and I’ve been tobacco free ever since. I do not crave cigarettes, I am actually a little disgusted by the smell of them. Before when smoking i was constantly out of breath and if I did the slightest bit of exercise I could feel it in my lungs. Now even with vaping I feel so much better. I am never out of breath and never feel groggy. I would recommend vaping to anyone who is trying to stop smoking tobacco. Any true smoker can tell the difference within a weeks time.
