Answer:
COPD (Chronic Obstructive Pulmonary Disease) can be triggered by tobacco smoke, mold, and perfumes. COPD is a progressive lung disease that makes it hard to breathe, and it is often caused by long-term exposure to lung irritants, such as cigarette smoke, air pollution, chemical fumes, or dust. Secondhand smoke and exposure to other lung irritants, like mold and strong chemical odors, can also contribute to the development of COPD or make the symptoms worse in people who already have the condition.
