Big drop in heart attacks follow smoking bans

The new studies should grab the attention of cities as well as states that still permit smoking in (at least certain sections of) bars, casinos, restaurants, and other public places.

Overall, 32 states and many cities in the United States have passed some type of law prohibiting smoking in public spots. (You can check out the American Nonsmokers' Rights Foundation to find out if your local community has a ban.)

In addition, England, France, Ireland, Italy, Norway, and Scotland have passed such bans.
