Heart attacks plummet after smoking ban imposed

A smoking ban in one Colorado city led to a dramatic drop in heart attack hospitalizations, according to a new study that is considered the best and longest-term research to show such a link. The rate of hospitalized cases dropped 41% three years after the ban of workplace smoking in Pueblo, CO, took effect. There was no such drop in two neighboring areas, and researchers believe it's a clear sign the ban was responsible.
