A clinical report from the American Academy of Pediatrics warns that energy drinks --  Red Bull, Monster, Rockstar and many others -- should be off limits to children and teenagers because they contain high levels of caffeine and other stimulants. The AAP report says energy drinks often get confused with sports drinks, and that the beverages are generally understudied and overused. Sales of energy drinks are expected to approach $9 billion in the U.S. this year.
