Another interesting fact: nicotine from second hand smoke can be detected in urine, blood, and hair samples from children (or non-smoking adults) of smokers. Infants who die of SIDS have been found to have higher concentrations of nicotine in their blood than healthy infants. Second hand smoke has been shown to cause frequent respiratory infections (especially in children) as well as more ear infections, more frequent and more severe asthma attacks in those with asthma, and more frequent and severe exacerbation/infections in those with Cystic Fibrosis.
Yes, I know what it is. To clarify, I meant what specifically did you want to know if anybody knew about it? Are you wanting more information about what the effects are? Or just seeing what knowledge we all have?
Environmental tobacco smoke and passive smoking are other names of second hand
Measurements of cotinine show that exposure to secondhand smoke has steadily decreased in the United States over time. During 1988–1991, almost 90 of every 100 (87.9%) nonsmokers had measurable levels of cotinine. During 2007–2008, about 40 of every 100 (40.1%) nonsmokers had measurable levels of cotinine. During 2011–2012, about 25 of every 100 (25.3%) nonsmokers had measurable levels of cotinine.
