The headline refers to a review of the effects of smoking bans in 21 countries, including England and Scotland. This found fewer admissions to hospitals for heart attacks and strokes following smoking bans. However, the bans didn't appear to encourage more people to stop smoking. Some studies included in the review found a bigger reduction in heart attacks and strokes among non-smokers – who are no longer exposed to smoke in public places – than smokers, who are still exposed to their own smoke.
