Nearly 1.7 million deaths linked to second-hand smoke in 2023, study finds

The study found 767 million exposed children and 1.66 million premature deaths, while women and children faced the highest burden.

  • On Tuesday, The Lancet published a study reporting that 2.71 billion people were exposed to second-hand smoke in 2023, contributing to 1.66 million deaths and 44.8 million DALYs globally.
  • People near smokers inhale unfiltered 'sidestream smoke' carrying higher concentrations of toxic compounds, while population growth in Africa and the Middle East has kept exposure numbers stable despite declining smoking prevalence since 1990.
  • Among the 2.71 billion people exposed were 767 million children aged 0 to 14, with exposure causing an estimated 5.2 million respiratory tract infections in children during 2023.
  • Women face disproportionate risks in regions where smoking prevalence is low, with researchers noting that 'Despite this substantial burden, exposure remains rarely acknowledged as a major risk factor for female health.'
  • Tobacco remains a leading cause of disease globally, with 8 million deaths linked to smoking-related illnesses in 2023; the study urged governments to strengthen public and home tobacco controls to protect vulnerable populations.
