What is Passive smoking?
{{no sources|date=December 2023}} [[File:Smoke-by-a-window-in-a-pub.jpg|thumb|Smoke in an [[Ireland|Irish]] [[pub]], before a smoking ban in pubs came into effect. ]] Someone [[smoking]] a [[Pipe (smoke)|pipe]] or a [[cigarette]] will [[wikt:exhale|exhale]] tobacco smoke. People who are physically close to the smoker will [[wikt:inhale|inhale]] the smoke. This is called '''passive smoking'''. Even though passive smokers don't smoke themselves, they are still affected by the smoke. The effects of inhaling tobacco smoke are similar to those of smoking. These effects were first studied in the 1970s. Since then, many countries have made [[Law|laws]] that limit who is allowed to smoke, and [[smoking room|where smoking is allowed]]. As an example, many countries made laws that made smoking in [[Restaurant|restauarants]] [[illegal]], to protect the [[Employee|staff]] against the effects of passive smoking. {{Stub}} [[Category:Smoking]]
