Recently a research study said that after a county-wide smoking ban was implemented hospital admissions due to heart attacks decreased 70 percent for non-smokers. But the smoker’s hospitalizations for heart attacks still unchanged. Actually second hand smoke or environmental tobacco smoke (ETS) means the involuntary inhalation of smoke from tobacco products. Evidence exists that experience to second hand tobacco smoke causes death, disease, and disability. Passive smoking is main reason to ban smoking in indoor places. Because second hand smoke causes cardiovascular disease, lung cancer, bronchitis and asthma like as smokers. That reports shows that non-smokers living with partners who smoke in the same home have a 20-30% greater risk of lung cancer, and those exposed to cigarette smoke in the workplace have an increased risk of 16-19%.
The study seems to be the first to explore the effect of public smoking bans on heart attacks in non-smokers. According to the specialists if the non smoker stays with smoker with 30 minutes there is a significant chance to increase the risk for heart attack. Because of tobacco smoke contains carbon monoxide, a known blood vessel constrictor. The effect on carbon monoxide on blood vessels may cause the amount of oxygen carried out in the blood to reduce significantly. In fact this study was done in Monroe County (IN) and Delaware County (IN). Delaware County had not implemented any smoking ban during the study period while Monroe County prohibited smoking in restaurants, bars, retail spaces and workplaces.
