Although I have been studying electronic cigarettes for several years, sometimes it feels like the same questions keep coming back around: Are e-cigarettes safe? What are the health effects of vaping e-cigarettes? Is vaping better than smoking?

These questions come from parents, policy-makers, reporters, patients and health care workers. However, there are many parents here in La Jolla who could tell you firsthand that e-cigarettes are addictive and dangerous. These parents learned about the dangers of vaping e-cigarettes when their own children became addicts.
