New Study of National Heart Attack Admissions and Mortality Finds No Evidence of a Short-Term Effect of Smoking Bans

Researchers from the RAND Corporation, the Congressional Budget Office, the University of Wisconsin, and Stanford University have just published a study showing that smoking bans do not reduce heart attack rates in towns that impose them.

"The most important finding of this study is that there are just as many smoking ban communities in which heart attack admissions and mortality have increased in comparison with control communities as there are smoking ban communities in which heart attacks have decreased relative to control communities. The mean difference was found to be zero."

A similar study by David Kuneman and Michael McFadden reached the same conclusion five years ago.
