What diseases are commonly associated with tobacco use?

The association of tobacco use with cancer and upper respiratory diseases is well-documented. Tobacco smoke contains numerous carcinogens, which can lead to various types of cancer, particularly lung cancer, as well as cancers of the mouth, throat, esophagus, and bladder. Additionally, tobacco use contributes significantly to upper respiratory diseases, including chronic obstructive pulmonary disease (COPD), emphysema, and chronic bronchitis, both of which are prevalent among users. The harmful chemicals in tobacco irritate the airways and lungs, leading to long-term respiratory problems and increased susceptibility to infections. This highlights the critical health risks linked with tobacco use, making it essential for both education and prevention efforts focused on smoking cessation.
