Graphic PSAs: Effective tools, or too shocking?

(CBS News) Cigarette smoking kills more than 400,000 Americans every year, including deaths linked to secondhand smoke.

So the Centers for Disease Control and Prevention is pulling out all the stops to try to get people to stop smoking.

It's just released some very graphic ads it hopes will help people quit, or turn off others from even starting.

The $54 million campaign is as shocking as it is controversial - it tries to scare smokers into kicking the habit.

In England, another ad is tackling the difficult subject of "teen date rape" in an equally graphic manner. It's called, "If You Could See Yourself."

The question is: Do ads like these really work, or go too far?

"CBS This Morning: Saturday" co-hosts Rebecca Jarvis and Ben Tracy screened some of the ads with "CBS This Morning" contributor Lee Woodruff and Matt MacDonald, executive creative director of JWT Advertising, one of the world's largest advertising agencies.
