My 26 year old son has smoked since he was 16. He was up to 2 packs a day. Since he was in sales, he knew it wasn't good to smell like cigarette smoke, when he was in meetings, so he tried the e-cigarettes. www.greensmoke.com/christmas I am proud to say that he hasn't had a real cigarette for 13 days. He chose the chocolate flavor and medium nicotine. He said that his taste buds are back already and now he can "vape" where ever he pleases. (Even in those meetings.) There is no smoke, they only give off a water vapor. Since he is an Apple/computer type guy, he likes the designs on the cartridges and having a funny "cigarette" that has to be charged. He does have ongoing costs, but nothing like with analog cigarettes. I know there is a site dedicated to vaping, but I don't have a link.
