A record number of Americans have decided not to drink at all; why?

A record number of Americans have decided not to drink at all. A Gallup survey of 1,200 adults living in all 50 states has found that 54% of them do consume alcohol, the lowest reading since the polling organization started tracking Americans’ drinking habits in 1939. Do you drink?  Have you quit or drink less than before? Nicholas Gilpin, Professor of Physiology and Director at the Alcohol & Drug Abuse Center of Excellence at LSU Health New Orleans, joins Dave Cohen to talk about those trends.
