How does cigarette smoke affect lung health?

1. It strengthens lung capacity

2. It has no effect on lung health

3. It causes long-term respiratory issues

4. It improves oxygen absorption

The correct answer is: It causes long-term respiratory issues

Cigarette smoke has a significant detrimental impact on lung health, which is why the choice that indicates it causes long-term respiratory issues is correct. Smoking introduces a variety of harmful chemicals into the lungs, including tar, nicotine, and carbon monoxide, which can lead to chronic conditions such as chronic obstructive pulmonary disease (COPD), emphysema, and chronic bronchitis. These conditions result from the damage to the lung tissues and airways, leading to reduced lung function over time. Chronic exposure to cigarette smoke can also impair the body's ability to fight off respiratory infections, and it contributes to inflammation and obstruction in the airways. This compounded effect on lung health not only makes breathing more difficult but can also diminish the overall quality of life for smokers and those exposed to secondhand smoke. In contrast, the other options suggest positive or neutral effects on lung health, which does not align with the extensive body of scientific evidence that demonstrates the harmful consequences of smoking. The idea that cigarette smoke strengthens lung capacity or improves oxygen absorption is fundamentally inconsistent with what is known about the physiological impacts of smoking. Moreover, claiming there is no effect overlooks the well-documented risks associated with tobacco use.
