Lets think of the danger here...
Energy drinks have so much shit in them they are jokingly thought to make ones perception of time freeze, your body glow in the dark, make you immune to radiation... all sorts of gamer/geek humor, but, for the most part, they're just another "bad drink".
But... according to this article from the +Escapist
, a 14yo boy goes comatose after 4-liters. That is... two 2-liter bottles, approximately four 20oz bottles, or approximately six 12oz cans of soda.
These 4-liters of e-drink were consumed over 16 hours. That's an entire waking day. I can consume that much soda easy. Anyone in a social situation can. 4-liters is not really a lot.
E-drinks are generally considered much much worse than soda (which isn't considered particularly good for you either), but if 4-liters of an energy drink is enough to land a 14yo in the hospital, then whatever energy drink it was better have a serious investigation on it's hands.
What happened to this kid should be the results of years of heavy consumption of this stuff, not a single 16 hour, 4-liter (or twelve 12oz cans) binge.
(To be fair to the e-drinks, however, there is no mention of how heavily this kid consumed these drinks prior to this one 16-hour period. For all we know he could have been drinking nothing but e-drinks since he was 10)
