Smoke-free policies are regulations that prohibit smoking in certain areas to protect public health. These policies are often implemented in places like restaurants, offices, and public parks to reduce exposure to secondhand smoke, which can harm non-smokers. By creating smoke-free environments, communities aim to promote healthier lifestyles and reduce smoking rates. Many countries and cities have adopted smoke-free laws, which can vary in scope. Some policies may ban smoking in all indoor public spaces, while others extend to outdoor areas. These regulations are part of broader public health initiatives to decrease the prevalence of tobacco use and improve air quality for everyone.
