The Boston Globe ran an article on the ban I mentioned yesterday. Scientificaly, this is too smal a population to generalize the effects such a ban would have across the board, but still.....
"Helena's smoking ban was adopted by voters in June and lasted for six months, until enforcement was suspended after a legal challenge. It ''led to an immediate and dramatic decline in the number of heart attacks we saw,'' from an average of seven a month to three, said Dr. Richard Sargent.
Heart attacks climbed back to their usual level after smoking returned to bars, restaurants, casinos, bowling alleys, and other public places in December."
