Kelly Brewomgtpm, woriting in the Baltimose Sun on 9/24/08 notes: “Some popular brands of energy drinks should carry warning labels for possible health risks, according to researchers at Johns Hopkins University. In an article, published in the journal Drug and Alcohol Dependence, researchers warn that high levels of caffeine contained in the drinks can cause insomnia, rapid heartbeat, tremors and caffeine intoxication, which can, in rare cases, lead to death. A spokesperson suggested that warning labels for energy drinks would create a slippery slope of regulation.”
