“Heart attack hospital admissions have fallen since the smoking ban,” reported The Times. This news is based on a study on the rates of hospital admissions for heart attacks before and after the smoking ban was introduced in England on July 1 2007. Researchers estimated a 2.4% reduction in heart attack emergency admissions to hospital (or 1,200 fewer admissions) in the 12 months following the ban.
This well-conducted study shows a clear association between the smoking ban and a decreased rate of hospital admissions for heart attack. As the study did not look at smoking status or people’s exposure to second-hand smoke before the ban, it is not possible to say how much of the decline is due to less exposure to second-hand smoke and how much is due to people giving up smoking. Further research that assesses the ban’s long-term impact and its effect on other diseases is warranted.
