Secondhand smoke affects 2.7 billion people and kills 1.66 million per year, study reveals

ZAP Notícias8 September 2026 at 10:30

About 2.71 billion people are exposed to secondhand smoke worldwide, including 767 million children under 15 years old. This exposure was responsible for 1.66 million deaths in 2023, according to a study that analyzed the issue.

The research authors highlight that exposure to secondhand smoke constitutes a globally recognized health risk for which there is no safe inhalation level. The study analyzed all scientific papers published on the PubMed platform, an online library managed by the United States National Institutes of Health, referring to the period between 2010 and 2025.

The objective of the research was to assess the impact of secondhand smoke on nine distinct health areas, although the article appears cut off and it is not possible to identify all these areas. The study represents a comprehensive review of the existing scientific literature on the effects of exposure to tobacco smoke in non-smokers.
