The updated Cochrane review containing more up-to-date research found that countries who imposed smoking bans found their populations benefited from reduced exposure to passive smoke, specifically cardiovascular disease.
Researchers found that of the 44 observational studies which specifically assessed cardiovascular disease, 33 of these studies reported evidence of a significant reduction in heart disease following the introduction of these bans. Researchers also found that the greatest reduction in admissions for heart disease following smoking legislation were identified in populations of non-smokers.
Review author, Professor Cecily Kelleher, from University College, Dublin, said: “The current evidence provides more robust support for the previous conclusions that the introduction of national legislative smoking bans does lead to improved health outcomes through a reduction in second hand smoke exposure for countries and their populations. We now need research on the continued longer-term impact of smoking bans on the health outcomes of specific sub-groups of the population, such as young children, disadvantaged and minority groups.”
