I am 61 and I have smoked since I was 18 and like many others I tried many times to quit. I have been using the e-cigs since Thanksgiving 2009. I went to Alaska on a plane and I used it, no one complained, a lot of people asked me questions about them and I wrote down the web site address for several of them. Every where I go I am asked about them and I give all the info I can. My husband loves the fact that I don’t smoke in the Tahoe , he doesn’t mind the vaporing. I have used them in restaurants, doctors offices, and Walmart. I think I might need to go to work for them. Thank you for allowing me tell you how great they are.
