A new study from Scotland provides what US public-health experts say is the strongest evidence yet that public bans on smoking improve health by reducing exposure to secondhand smoke.
Published in the latest issue of the
New England Journal of Medicine, the study finds that hospital admissions for heart attacks and acute coronary problems fell 17% overall, and even more for nonsmokers, in the year after Scotland banned smoking in
public places.
“There has long been a claim from smokers that they are affecting their own bodies, and why should the public care?” asked David Cohen, director of cardiovascular research at Saint Luke’s Mid America Heart Institute in Kansas City, Missouri, who wasn’t involved in the study. “This shows that the public should absolutely care…that is an incredibly powerful finding.”
The study found that nonsmokers accounted for 67% of the overall reduction in heart disease hospitalizations, said Jill Pell, the University of Glasgow professor who led the study. Nonsmokers saw a 20% reduction in their hospital admissions following the ban. Smokers’ admissions were down 14%.
