Jacob Sullum on Scottish Smoking Ban and Heart Attack Study

As usual, Jacob Sullum has an insightful commentary on the Scottish smoking ban and heart attack study. He also comments on the Wales study and correctly points out that many locations that adopt smoking bans are invariably going to see declines in heart attacks in subsequent months or years. You can't focus only on those locations. What is needed is a systematic study of multiple locations (like that conducted by Dave Kuneman and Michael McFadden, which found no significant immediate effect of smoking bans on heart attacks).
