Nothing is harmless. To have a conversation that isn't just scare mongering and opinion pushing you have to actually mention risk factors. From everything I've read, e-cigs are so almost harmless that it doesn't even bear mentioning. Studies like this show that e-cigs are harmful on about the same level as eating too much kale is harmful. People that fixate on the small but technically true fact that it is "harmful" are doing much more harm to people's health than e-cigs, because each comment to that effect potentially dissuades another smoker from making the switch.
