Which health risk is associated with smoking any substance?

• A. Decreased risk of respiratory illness
• B. Increased risk for respiratory illness
• C. No health risks
• D. Immunity from infections

Answer: (B)

Smoke inhalation from any substance brings irritants, particulates, and toxic chemicals into the lungs. These substances damage the lining of the airways, impair the tiny hairs (cilia) that help clear mucus, and trigger inflammation. That combination weakens the lungs’ defenses and raises the likelihood of respiratory illnesses such as bronchitis, pneumonia, asthma exacerbations, and COPD. Because of this, the statement that there is an increased risk for respiratory illness is the best choice. The other options—decreased risk, no health risks, or immunity from infections—don’t fit because smoke always introduces harmful substances that harm the respiratory system and immune defenses.
