ATLANTA (AP) - A government study suggests that secondhand smoke
is a very serious public health threat.
The study by the CDC says a smoking ban in a Colorado city led
to a dramatic drop in heart attack hospitalizations within three
The study, the longest-running of its kind, showed the rate of
hospitalized cases dropped 41 percent in the three years after the
ban of workplace smoking in Pueblo, Colo., took effect. There was
no such drop in two neighboring areas. Researchers believe it's a
clear sign the ban was responsible.
One of the researchers says the study suggests that secondhand
smoke may be a terrible and under-recognized cause of heart attack
deaths in this country.
At least eight earlier studies have linked smoking bans to
decreased heart attacks, but none ran as long as three years.
