Jon Lusher (L) and Bret Wagner try different flavors of electronic cigarette vapor as they shop at the Vapor Shark store on April 24, 2014 in Miami, Florida. Brandon Leidel, CEO, Director of Operations Vapor Shark, said he welcomes the annoucement by the Food and Drug Administration that they are proposing the first federal regulations on electronic cigarettes, which would ban sales of the popular devices to anyone under 18 and require makers to gain FDA approval for their products.
