Smoking in public places can negatively impact those who do not smoke through secondhand smoke exposure. Secondhand smoke contains over 7,000 chemicals, many of which are carcinogenic. Exposure to secondhand smoke has been linked to various health conditions like heart disease, lung cancer, and asthma attacks. Many communities have implemented restrictions to protect citizens from secondhand smoke in public places like restaurants, parks, and buildings. However, more regulations may still be needed to achieve truly smoke-free environments for all.
