One of the most effective things that I have found when explaining to people about the benefits of vaping is talking money. That, for some reason, is what people will really listen to.
I usually give them a very brief explanation of "It's an e-cigarette. It works by vaporizing liquid that has nicotine in it, which you inhale. The initial kit/set-up that I got was about $60.00. The real cost savings is that you can spend only $30.00 a month on the e-liquid, compared to say $180.00 for a pack-a-day habit of traditional cigarettes. That combined with all the other bonuses like I'm not out of breath, not having the tobacco "scent" on me all the time, and being able to quit traditional cigarettes made it a great choice for me. IF you are interested, I can give you a card with some information, and my email address if you like. I'm always happy to help others quit smoking traditional cigarettes and save money."
I've only converted family members and close friends, but I'm always willing to talk with folks about them, but I try not to press. I have handed out the cards I made, but have never had anyone email me. I can only hope that they make their way to ECF and become analog free.
