What does your doctor say? Went to my cardiologist a couple of weeks ago, EKG and review of my echo, I had some e-cigs with me. (Even if I can't use them in a public or medical building, for example, is no reason for me not to carry them.) But apparently not many people do carry them. The Doctor got very excited, took out his i-phone and asked if he could take a picture of them to show to some of his other patients. (He had heard about e-cigs, but I guess none of his patients had ever had any to show him) That makes three physicians I've seen lately that think I'm on the right track vaping rather than smoking.
