How nicotine is linked wih emphysema?

Nicotine, a primary component of tobacco, contributes to the development of emphysema by damaging lung tissues and promoting inflammation. It leads to the destruction of alveoli, the tiny air sacs in the lungs responsible for gas exchange, reducing lung function. Additionally, nicotine enhances mucus production and impairs the body's ability to clear out toxins, further exacerbating respiratory issues. The overall impact of nicotine and other harmful substances in tobacco smoke significantly increases the risk of developing emphysema and other chronic obstructive pulmonary diseases (COPD).
