As the FDA prepares to ban caffeinated energy drinks, the manufacturers of Four Loko say they will reformulate their drink without the caffeine. Thomas Gould, professor of psychology and neuroscience at Temple, says that would probably make the drink a bit safer: "It takes your body a while to figure out how much alcohol's in there, so if you’re consuming a lot quickly it's easier to get at a toxic level quicker." He says that when alcohol is combined with caffeine, people tend to consume more of it.
