CVS Caremark plans to stop selling tobacco products at its more than 7,600 drugstores nationwide, according to NBC News. CVS, the second-largest drugstore chain in the country, said Wednesday that selling cigarettes side-by-side with medicine undermines the mission of promoting good health. The chain will lose about $2 billion in revenues annually by halting sales of tobacco, but the CVS Pharmacy president said the move makes sense for a brand now positioning itself as a health care company. U.S. Health and Human Services Secretary Kathleen Sebelius said the ban was "an unprecedented step in the retail industry" and urged others to follow CVS' lead.
