Smoke inhaled from the burning tobacco products or others.
Smoke that goes directly into the air from burning tobacco.
The smoke produced by the smoldering tip of a cigarette, cigar, or pipe, as well as the smoke exhaled by the smoker, constitutes what is commonly referred to as second-hand smoke. This term encompasses both the emissions from the burning end of tobacco products and the smoke exhaled by individuals who smoke. Second-hand smoke poses health risks to those who are exposed to it, as it contains various harmful substances and compounds.
