I chain smoked for over 40 years and started using an electric cigarette about two and a half years ago. I haven't had a cigarette since the day I got it. No odor, no carcinogens, no ash, no fire risk and no health risk and I even used it in hospital during recovery from surgery with my Doctors approval and consent. Liberal smoking police can do nothing about it. I love it and highly recommend it to anyone wanting an alternative to cigarettes.
