Smoke-free laws are regulations that prohibit smoking in certain public places to protect people from the harmful effects of secondhand smoke. These laws often apply to areas like restaurants, bars, workplaces, and public transportation. The goal is to create healthier environments for everyone, especially for children and individuals with respiratory issues. Many countries and cities have implemented smoke-free laws as part of public health initiatives. These laws not only reduce exposure to secondhand smoke but also encourage smokers to quit. By promoting smoke-free environments, communities aim to improve overall health and well-being for their residents.
