Global Tobacco Control Updates
The Cochrane Collaboration recently assessed the impact of smoking bans in indoor public places and workplaces on health outcomes and exposure to secondhand smoke. The assessment is based on 77 studies from 21 countries published through until February 2015. Of the 77 studies, 44 examined smoke-free effects on cardiovascular health, 21 on respiratory health, 7 on perinatal health, and 11 on tobacco-related death. Participants in the 77 studies included smokers and nonsmokers.
- 33 of the 44 studies examining effects of smoking bans on cardiovascular health found that smoking bans significantly reduced heart-related events, such as heart attacks.
- 5 of the 6 studies examining effects on strokes found smoking bans significantly reduced stroke events.
- Of 21 studies examining effects related to respiratory health, 6 found that smoking bans significantly reduced hospital admissions for chronic obstructive pulmonary disease and 7 found that bans significantly reduced hospital admissions for asthma.
- Of 11 studies examining effects on smoking-related death, 8 found that smoking bans significantly reduced smoking-related death.
- There is no safe level of exposure to secondhand smoke. Exposure to secondhand smoke causes disease and death.
- Comprehensive smoke-free laws for all indoor public places and workplaces improve public health and save lives.
- All countries should enact and implement comprehensive smoke-free laws to protect non-smokers from the harms of secondhand smoke and help smokers to quit.
