Ngu NLY, et al. - This study entailed an analysis of the literature data on the link between environmental tobacco smoke and peripheral arterial disease. Researchers also identified the public health implications of the findings. Moderate quality literature evidence supported a link between exposure to environmental tobacco smoke and development of peripheral arterial disease or clinically significant arterial injury in non-smokers. Data suggesting potential detrimental effects offered support to ongoing restrictions on freedom to smoke in public areas, including the workplace and had implications for those exposed in the home environment.
