What health issues are commonly linked to smoking?

Smoking is a significant public health concern due to its well-established links to a variety of serious health issues. The correct answer identifies lung cancer, heart disease, and respiratory problems as common health issues associated with smoking.

Lung cancer is one of the most prominent health risks linked to tobacco use. Cigarette smoke contains numerous carcinogens that can lead to the development of cancerous cells in lung tissues. Heart disease is also closely tied to smoking; it can contribute to the development of atherosclerosis, where the arteries become narrowed and hardened due to plaque buildup. This leads to an increased risk of heart attacks and other cardiovascular complications. Additionally, smoking harms the respiratory system, contributing to chronic obstructive pulmonary disease (COPD) and other respiratory illnesses, making breathing difficult and increasing susceptibility to infections.

The other options include health issues that are not primarily associated with smoking. Diabetes, obesity, and hypertension are influenced more by lifestyle factors such as diet and physical activity rather than tobacco use. Muscle degeneration, arthritis, and insomnia are not directly caused by smoking, although smoking can exacerbate certain conditions or interfere with sleep patterns. Anemia, migraines, and skin disorders may occur in smokers, but they are not the primary health risks commonly discussed in relation to smoking.
