The research, which was carried out by the Cochrane Tobacco Addiction Group, examined the impact the smoking ban has had on 21 countries, including England and Scotland. It particularly found a decrease in hospital admissions amongst non-smokers, who are no longer exposed to smoke in public spaces.
Researchers examined a total of 77 studies, examining the effect of the ban on areas such as cardiovascular health, respiratory health (conditions such as asthma), the health of newborn babies and the number of deaths from smoking-related diseases.
However, while the evidence suggested positive results in almost every area, it is difficult to know for sure whether the smoking ban is directly linked to the results of the study. For example, researchers may have found a cut in heart attacks thanks to a ban of trans fats in certain countries. It is also important to point out that the study didn't suggest the number of people smoking was dropping, either.
With that that said, even if the only result of the smoking ban is to protect non-smokers from suffering ill-health by being exposed to harmful passive smoking, it is still a positive result.
