A smoking ban is a law or regulation that prohibits smoking in certain public places, such as restaurants, bars, and parks. The primary goal of these bans is to protect non-smokers from the harmful effects of secondhand smoke, which can lead to serious health issues. Many countries and cities have implemented smoking bans to promote public health and create cleaner environments. These bans often include designated smoking areas, where smoking is allowed, but they aim to limit exposure to smoke in crowded or enclosed spaces. The effectiveness of smoking bans has been supported by research showing a decrease in smoking rates and improved air quality in areas where they are enforced.
