There aren't interest groups buying ad time for scaremongering or people beating the drum for moral superiority about the evils of caffeine... no. But energy drinks have gotten a bit of a bad wrap, and four loko with the caffeine and alcohol got banned... and if you have a heart condition or anxiety your doctor is going to advise you to lay off the coffee. Isn't that enough?

Or does it have to become a social evil for it to count?
