Study shows secondhand smoke could cause heart attacks

Lighting up in public places is starting to become a thing of the past, and a new study says it’s keeping people healthy.
   
In this edition of Health Report, a study by the centers for disease control says a smoking ban in one Colorado city is the reason for a dramatic drop in heart attack hospitalizations.
   
The study says the number of hospitalized cases dropped more than 40 percent in three years in Pueblo, Colorado, after the city banned workplace smoking.
   
Researchers say secondhand smoke may be an under-recognized cause of heart attack deaths across the U.S.
