This 10-year population-based study was conducted to determine the effect of anti-smoking legislation in Toronto, Canada on admissions to hospital for cardiovascular conditions, specifically heart attacks, angina and stroke, and respiratory conditions asthma, emphysema, and pneumonia or bronchitis.

The largest decline in hospital admissions occurred after the 2001 ban of smoking in restaurants. This included a 17% decrease in the crude rate of admission for heart attacks, a 33% decrease in rates of admission for respiratory conditions and a 39% decrease because of cardiovascular conditions.
The authors conclude that their findings "are consistent with the evidence that exposure to second-hand smoke i
