I can almost see teenagers across America, as well as white-collar workers on Wall Street, foaming at the mouth because of this statement. I admit, I'm not an energy drink buyer, period, but I can understand their mass appeal now. What I feel will do them in will be the ever-broadening scope of the Food and Drug Administration. At the moment the FDA is working its way under the tobacco industries' skin and could find its way into regulating certain aspects of energy drinks including safety, ingredients, and manufacturing, within the next decade. That could be a crushing blow for energy drink giant Monster Beverage, which generates more than 90% of its sales from its energy drinks.
