CVS is planning to stop selling tobacco products in its stores.
The company says it is the first national pharmacy chain to do so.
According to CVS Caremark, the move will cost it two billion dollars a year in lost revenue.
But it wants to support "the health and well-being" of its customers.
The tobacco products are expected to come off the shelves by October.
The White House released a statement from President Obama applauding the move.
