Three studies highlight passive smoking risks

New research shows that passive smoking leads to an increased risk of death, heart attacks, and can mean the slower healing of wounds.The British Medical Journal online published research that showed for non-smokers who live with a smoker, there is a 15% higher risk of death. It also published research which found that the number of heart attack admissions in a city in the US fell by 40% during a ban on smoking in public places and workplaces in 2002. The ban was later overturned.
