Does CVS "really care" about lung cancer or rather the boost of its reputation and stock? And is a sales stop enough to reduce the number of smokers to prevent lung cancer?

CVS announced today to stop selling cigarets. Read the news from several sources here:

Is a stop of selling tobacco cigarets enough for lung cancer prevention? Wouldn't be education more effective, and something we'd need more? 

And here is an interesting statement: "CVS Caremark's stock price was down 55 cents, or a little less than 1 percent, to $65.56 in midday trading." Read more here:
