What diseases are commonly associated with tobacco use?

Tobacco use is primarily linked to an increased risk of several serious health conditions, notably cancer and heart disease. Smoking is a major cause of lung cancer, which is one of the deadliest cancers worldwide. It also contributes to cancers of the mouth, throat, esophagus, bladder, and other organs. Furthermore, tobacco smoke has a detrimental effect on cardiovascular health by promoting the development of heart disease. It damages blood vessels, increases blood pressure, and leads to the buildup of plaque in arteries, which can result in heart attacks and strokes.

The other options list conditions that may have some association with tobacco use but are not as directly or significantly linked as cancer and heart disease. For example, while skin diseases can be influenced by various factors including smoking, they do not represent the primary or most severe consequences of tobacco use. Similarly, while respiratory infections and diabetes can be affected by tobacco, their connection is not as strong or established when compared to the clear evidence linking smoking with cancer and heart disease.
