I was diagnosed with emphysema last year. I'm only 27. I've been smoking a pack a day for roughly 17 years, but haven't had but 2 or 3 cigarettes in the last month thanks to my new e-cigarette. I feel much healthier and more energised/motivated now. My question is, is this thing harmless, the lesser of two evils, or killing me in some new way?plz help me
