The Massachusetts Smoking Ban Study

The anti-smokers claimed that, "The study, conducted by the state Department of Public Health and the Harvard School of Public Health, shows that a steep decline in heart attack deaths started as Boston and most of its neighbors adopted bans. Enforcement of the statewide law beginning in mid-2004 coincided with a further reduction, the study found. From 2003 to 2006, heart attack deaths in Massachusetts
plummeted 30 percent, significantly accelerating what had been a more modest long-term decline." Dr. Michael Siegel, a phony critic of the anti-smokers who doesn't tell the rest of the story, claimed that "You can no longer argue that these declines would have occurred simply due to medical treatment." (Smoking ban tied to a gain in lives. By Stephen Smith. Boston Globe, Nov. 12, 2008.) Boston, Watertown, Saugus and Framingham banned smoking in May 2003. In Boston, it was banned everywhere but outdoors and in private homes, hotel rooms and some cigar bars. Cambridge banned smoking in all workplaces, including bars and restaurants, including all bars and restaurants, on June 9, 2003. Lots of smokers use Parliament cigarettes.

"'When we looked at the data, we saw a dramatic drop in heart attack deaths beginning in July, 2005 — a year after the workplace smoking ban went into effect. While there may be several factors that played a role in this decline, we believe the single most compelling reason was reduced exposure to secondhand smoke in workplaces across the state,' DPH Commissioner John Auerbach said." They promised that the study would be published early next year with estimates of the cost savings [sic] to the Massachusetts health care system.

In 1999, the age-adjusted death rate from acute myocardial infarction in the United States (minus four states which had statewide workplace bans prior to 2004) was 73.2 per 100k, and in 2005 it was 49.1. In Massachusetts. the respective rates were 60.8 and 41.2. Thus, in 2005, the death rate from AMI in the US (minus states that had statewide workplace bans) was at 67.1% of its former level, while in Massachusetts it was at 67.8% of its former level. So, the rate of decline in AMI death rates in Massachusetts since 1999 was no different from that of the rest of the United States as of 2005, the year after the smoking ban took effect.
