Most people can tell you about e-cigarettes and what harm they cause, the controversy. Some will tell you about the good that they do. What is the real difference between a traditional smoke and a vapor?Dr. Laura Dutra, along with a colleague, made an appearance on WAMC. She has authored a study about the correlation between the two types of tobacco and their use among younger kids.Dutra found that kids who had never smoked an e-cig were more likely to be smokers now. Those who were smokers, but smoked traditional cigarettes were more likely to still be smoking. Those who smoked e-cigs were more likely to plan to quit.
