End of 'tips from former smokers' PSA

The public service announcements from the CDC's tips from Former Smokers campaign are set to stop at the end of the month. The agency has run these PSA for the past 13 years. Real stories from real people about the harms of smoking. Joining us to discuss the significance of this cancellation is doctor and Professor Robert Jackler, founder of the Interdisciplinary Research Group at Stanford, which looked into the impact of tobacco advertising.
