Over 1.66 million people died globally in 2023 due to exposure to second-hand tobacco smoke, with women and children facing the highest health risks.
According to a global study published in The Lancet Public Health, around 2.71 billion people suffered from the harmful effects of passive smoking during the same period.
The research revealed that nearly one-third of the global population was exposed to tobacco smoke from others in 2023.
This exposure led to the loss of approximately 44.8 million healthy life years worldwide.
Researchers evaluated data across 204 countries and territories from 1990 to 2023 to assess the global impact of second-hand smoke.
The findings indicate that global exposure rates dropped by nearly 22 per cent over recent decades.
However, rapid population growth kept the total number of affected individuals largely unchanged. Exposure rates rose significantly in Sub-Saharan Africa, North Africa, and the Middle East.
The study highlighted that nearly 767 million children aged zero to 14 suffered from second-hand smoke exposure in 2023. Researchers noted this exposure caused around 5.2 million lower respiratory infection cases among children.
For adults, coronary heart disease emerged as the leading cause of death linked to passive smoking.
