According to World Health Organization (WHO) experts, as detailed in The Lancet, secondhand smoke claims the lives of 1 in 100 people worldwide.
Every year, around 600,000 people die globally from secondhand smoke exposure, including 165,000 children. These findings come from a comprehensive study analyzing data from 192 countries in 2004—the latest available at the time of publication.
Heart disease and lung cancer are the leading causes among exposed non-smokers, followed by asthma and other respiratory problems. Globally, 40% of children, 33% of male non-smokers, and 35% of female non-smokers involuntarily breathe in others' tobacco smoke.
Notable: Adult deaths from secondhand smoke occur across all countries, but child fatalities are concentrated mainly in low-income nations. These children are often already compromised by other infections, heightening their vulnerability.
