Researchers' Institute of Environmental Medicine at the Karolinska Institute in Stockholm along with researchers from the World Health Organization performed a global estimate of exposure to secondhand smoke and the impact of the disease that results in children and adults in 2004. The study, which examined data from 192 countries, just published in The Lancet, shows that the greatest impact was applied to the lower respiratory tract infections in children under 5 years (5 million and 939,000), ischemic heart disease in adults (2 million and 836,000), and asthma in adults (1 million 246 thousand) and children (651,000). Exposure to environmental tobacco smoke was then estimated to be the cause of death of over 600,000 people, 379,000 people for ischemic heart disease, 165,000 lower respiratory tract infections, asthma and 36,900 to 21,400 for lung cancer. see also: EFFECTS OF PASSIVE SMOKING HEALTH
