Reluctant to discuss whether he’s kicked his own smoking habit for good, the world’s most famous smoker signed a bill today that gives the FDA new authority to regulate tobacco. The FDA now has the authority to reduce nicotine levels in tobacco products, outlaw the use of ban candy flavorings and ban labels such "low tar" and "light." Cigarette cartons, according to the Associated Press will now have large graphic warnings. One of the law’s main objectives is to govern marketing campaigns, particularly those aimed at children. "I was one of these teenagers," Obama said. "And so I know how difficult it can be to break this habit when it's been with you for a long time."
