There is no risk-free level of exposure to secondhand smoke, according to a new report issued by the US Surgeon General.
Non-smokers exposed to secondhand smoke at home or work increase their risk of developing heart disease by 25 per cent to 30 per cent and lung cancer by 20 per cent to 30 per cent, the report says. Nearly half of all non-smoking Americans are still regularly exposed to secondhand smoke.
Exposure to secondhand smoke also causes of sudden infant death syndrome, respiratory problems, ear infections, and asthma attacks in infants and children, according to the report. (pi)
