I've been hearing a lot about the dangers of e-cigarettes. Is there a lot of research to back up these claims?

Yes, there is quite a bit of research on e-cigarettes and their safety. There are many studies that show that e-cigarettes can be used as a harm reduction tool for smokers who want to quit smoking or reduce their smoking habit. In addition, some studies suggest that e-cigarettes may have positive health benefits compared to regular cigarettes.
