A new study published in The Lancet Public Health (The Lancet) found that 2.71 billion people were exposed to secondhand smoke (SHS) in 2023, including 1.49 billion women and 767 million children under 15. While global exposure rates have declined since 1990, the number of people exposed has remained largely unchanged.
This research examined nine SHS-linked health outcomes, including cardiovascular diseases, cancers, COPD, lower respiratory infections, type 2 diabetes, otitis media, and asthma. Ischemic heart disease accounted for 12.0 million disability-adjusted life years attributable to SHS, making it the leading contributor to SHS-related health loss in 2023.
