For someone who has smoked as long as Dave has... there's no way in hell he smokes 1-2 cigarettes a day. In the opening sequence of the latest issue Dave's yucking it up and then displays the most typical smokers cough I've seen, heard and performed myself. No matter how long one has smoked... quitting will have benefits especially to one's throat and lungs which are vital to a singer's ability to perform. Switching to e-cigarettes will make a huge difference. I can say so... I'm almost 8 weeks tobacco free and it's amazing the improvements.
