tobacco smoke

Tobacco smoke is a complex mixture of chemicals produced when tobacco is burned. It contains thousands of substances, many of which are harmful. The key components include nicotine (which is addictive), tar (which can damage the lungs), and carbon monoxide (a toxic gas). Smoking can lead to serious health issues like lung cancer, heart disease, and respiratory problems. Additionally, secondhand smoke can affect non-smokers, particularly children, leading to similar health risks. Overall, tobacco smoke poses significant dangers to both smokers and those exposed to it.
