Today is a big day for CVS as the drugstore giant pulls all tobacco products from its stores. 

CVS Caremark announced its decision earlier this year to stop selling cigarettes and other tobacco products at all of their 7000 stores despite the estimated $2 billion cut in sales that would result from it. It's the first large retail drug chain to stop selling tobacco and it says it's doing it because it's "the right thing to do for our customers." The move also coincides with the company changing its corporate name to CVS Health.
