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

There is some research that shows that e-cigarettes are not as safe or effective as regular cigarettes, but there is also some research that suggests they may be safer than regular cigarettes. The jury is still out on this topic and more research needs to be done in order to fully understand the risks associated with e-cigarettes.
