A recent study revealed that about 2.7 billion people worldwide are passive smokers, meaning they are exposed to tobacco smoke without being active smokers. This exposure represents a global public health problem.
According to the research, it is estimated that this exposure to secondhand smoke resulted in 1.66 million premature deaths. This number represents a significant part of the total deaths attributable to tobacco recorded in 2023.
In total, tobacco was responsible for eight million deaths in 2023. This means that a small but significant proportion of tobacco-related deaths is associated with secondhand smoke exposure.
