(CNN) "Yessssss!" was my reaction to hearing the news that the U.S. Food and Drug Administration intends to regulate e-cigarettes, hookahs, vape pens, e-pipes and other electronic nicotine delivery products. As a family physician, I often have patients ask me about e-cigarettes. Some have seen advertisements and are wondering what they are; some have simply heard that e-cigarettes are safer than traditional cigarettes and want to know if this is true. E-cigarettes are included in the category of ENDS -- Electronic Nicotine Delivery Systems -- products that use a liquid containing nicotine and varying amounts of flavor, glycerin, propylene glycol and other ingredients. This liquid is heated into an aerosol that users then smoke. It is often referred to as "vaping."Jennifer Caudle says FDA regulation of electronic nicotine delivery systems is overdueMore research needed on long-term effects, especially as youth use skyrockets, she says
