Health risks of second-hand smoke
Second-hand smoke is a major source of indoor pollution and there is now clear evidence that environmental tobacco smoke damages the health of non-smokers.
Immediate effects of exposure to second-hand smoke for non-smokers can include:
- eye irritation
- headache and
- respiratory symptoms.
Adults with asthma can experience a significant decline in lung function.
Long term exposure to second-hand (passive) smoke causes lung cancer, heart disease and respiratory illness among adult non-smokers. It is a cause of respiratory disease, cot death, middle ear infection and asthmatic attacks in children.
A review carried out in 2004 by the UK Government-appointed Scientific Committee on Tobacco and Health (SCOTH) estimated that non-smoking adults exposed to second-hand smoke were 24 per cent more likely to develop lung cancer and 25 per cent more at risk of heart disease.
The Committee concluded that second-hand smoke is a serious public health risk.
