Can smoking too much cause your throat to close up?

No, smoking does not directly cause the throat to close up. However, smoking can cause a variety of health problems that can indirectly affect the throat and cause it to narrow or become obstructed.

Some of the health problems that smoking can cause include:

- Chronic bronchitis, a condition that inflames and thickens the lining of the bronchial tubes, which can lead to narrowing of the airways and difficulty breathing.

- Emphysema, a condition that destroys the alveoli in the lungs, which can also lead to narrowing of the airways and difficulty breathing.

- Lung cancer, which can cause a tumor to grow in the throat or trachea, blocking the airway.

- Laryngeal cancer, which is cancer of the voice box, can also cause the airway to become obstructed.

In addition, smoking can also cause the development of scar tissue in the throat, which can narrow the airway.

However, it's important to note that smoking is not the only cause of these health problems. Other factors, such as genetics, environmental exposures, and occupational exposures, can also contribute to these conditions.
