A "Non-Smoker" refers to an individual who does not engage in the act of smoking tobacco or other substances. This includes not using cigarettes, cigars, or pipes. Non-smokers may choose to avoid smoking for various reasons, including health concerns, personal preferences, or lifestyle choices. Non-smokers are often less exposed to the harmful effects of secondhand smoke, which can pose health risks to those nearby. Many public places have designated non-smoking areas to protect non-smokers from exposure. Additionally, non-smokers may benefit from lower health insurance costs and a reduced risk of smoking-related diseases, such as lung cancer and heart disease.
