NPR's Debbie Elliott reports an official for Philip Morris says the tobacco company is willing to open a dialogue on the possibility of some government regulation of tobacco. The announcement represents a shift from the tobacco company's long-time opposition to government oversight. Philip Morris says it's willing to discuss regulating cigarettes in such areas as sales to young people, research on safer products and disclosure of ingredients. But it still opposes regulation of tobacco as a drug - an issue that is currently the subject of a case before the Supreme Court. Anti-smoking groups greeted the announcement with skepticism about Philip Morris' motives.
