A July 13, 2007 article by Michael Siegel notes skepticism on HealthFactsAndFears.com about some claims made about smoking bans' benefits:
A study of trends in annual heart attack admissions through the emergency room by state refutes the conclusions of the Helena, Pueblo, Piedmont, and Bowling Green studies which concluded that smoking bans cause immediate, drastic declines in heart attacks. The study was conducted by Michael J. McFadden and David W. Kuneman. A preliminary version of the study appeared online in November 2005, while the final version, discussed on the American Council on Science and Health (ACSH) FactsAndFears blog, confirmed and strengthened the original findings.
