More than a decade after electronic cigarettes became broadly available in the United States, their merits are still being debated. Do these products help people quit smoking? How serious are the health risks associated with these products? In a two-part series, we hear from two researchers in tobacco control about their views. In part two, Stan Glantz, the Truth Initiative Distinguished Professor of Tobacco Control at the University of California San Francisco talks with Dr. Josh Sharfstein about his research into the harms of electronic cigarettes and the dangers of "dual use" of electronic cigarettes and traditional cigarettes. In an epilogue, Public Health On Call audio producer Matt Martin talks with Lindsay Smith Rogers about his personal history of tobacco use – including his efforts to quit with electronic cigarettes.
