Welcome to Vaping 101. As a physician and a parent, I know that you have questions about vaping. This comprehensive guide was designed to answer all of your questions and more - it will educate you on vaping and arm you with the information you need to educate your family and friends in hopes that they decide to stop or, hopefully, never even start to use electronic cigarettes. This guide contains a review of the latest research and surveys to provide the most accurate information, but more importantly, we break it down into plain language so that you and your teens (or young adults) will both be able to understand why vaping is such a dangerous activity.
