What are triggers of lung disease?

Triggers of lung disease include cigarette smoke or other permanent exposure or irritation of the lungs with air pollutants.^[23]
In allergic asthma, allergic reactions (e.g. pollen, dust mites, etc.) play an important role.^[24]
In non-allergic asthma, triggers may include infections, physical and psychological stress, polluted air, cold, or medications (e.g., diclofenac, ASA).^[24]
