NewzA study led by the Institute for Health Metrics and Evaluation (IHME) reports that exposure to secondhand tobacco smoke resulted in 1.66 million deaths among non-smokers in 2023. This figure highlights the persistent global health impact of tobacco smoke on individuals who do not consume tobacco products directly.
Despite the significant mortality rate, the data indicates a 22% reduction in the number of passive smokers compared to 1990 levels. This decline suggests progress in public health efforts to limit secondhand smoke exposure over the past three decades, even as the absolute number of deaths remains substantial.
