A recent study published in The Lancet Public Health found that in 2023 alone an estimated 2.7 billion people globally were exposed to secondhand smoke, including 767 million children under 15. After decades of anti-smoking campaigns and awareness-building about the dangers of secondhand smoke, why are billions of people still breathing in contaminated air? In conjunction with World Lung Day on the 25th of September, we’re joined by Prof Dr Anna Marie Nathan, consultant paediatric pulmonologist from Universiti Malaya Medical Centre to clear the air about the short- and long-term health consequences of secondhand smoke, why children are especially vulnerable to secondhand smoke in the home, as well as what we can do to help smokers quit to create a smoke-free environment for all.
