<human>: I've been hearing a lot about the dangers of e-cigarettes. Is there a lot of research to back up these claims?
<bot>: There is some research that suggests that vaping may be less harmful than smoking cigarettes, but it’s still early days and more research needs to be done. It's also important to note that vaping can expose you to nicotine and other chemicals that are not found in regular cigarettes, so it's best to use caution when using any type of tobacco product.
