Wanna show how many people have been injured or killed by an E cig in the last 10 years ?
Im willing to bet the only ones you will find are people hurt by the cheap shit gas station variety.
Any brand name ecig company have saftey blocks in their e cigs to keep batteries from over heating and exploding. Reputable studies that actualy say how they tested the e juice come back with no harmful toxins.
So, so far to me, if the consumer is smart and looks and buys a brand name e cig and e juice from a reputable company they are pretty safe. On the other side of it, if they try and cheap out then they get what they pay for, just like any other product on the market.
