What is the impact of secondhand smoke on cardiovascular health?
Secondhand smoke has been shown to have a significant impact on cardiovascular health. According to a 2005 study published in Circulation, the cardiovascular effects of secondhand smoke are nearly as large as those of smoking. Other studies, such as one published in the Lancet in 1996, have found an association between combined oral contraceptives and ischemic stroke, as well as an association between combined oral contraceptives and an overall increased risk of stroke. The US Department of Health and Human Services also released a report in 2006 that highlighted the health consequences of involuntary exposure to tobacco smoke.
