The E-cigs have not been proven to be bad for you. It's all conjecture, mostly from the tobacco conglomerate/FDA partnership.
As far as tobacco smoke with or without nicotine, hurting you, look at how it coats your home with a yucky dirty coat. Same thing coating your lungs. It may not be as harmfull to all, as they say it is , but I decided I didn't want it coating me nor my surroundings anylonger.
You're right, you're going to find the pros, cons, scams, truths and lies about everything, when you check Online. But so far, unless Uncle Sam jumps in

, it's still your choice....Do what is right for you, not your neighbor!!
