A common term refers to the visible cloud produced by the combustion of tobacco within a cigarette. This particulate matter comprises various chemicals and byproducts resulting from the burning process. For example, a person lighting and inhaling a cigarette will exhale this visible emission.
Understanding the composition and effects of this emission is crucial for public health initiatives and individual well-being. Historically, the understanding of its detrimental effects has driven the development of smoking cessation programs and stricter regulations on tobacco products. The health consequences associated with exposure, both direct and secondhand, are well-documented and remain a significant concern.
