Smoker's Lungs

Smoking is a major health hazard, causing over 100,000 deaths annually from lung cancer alone. Cigarette smoke contains over 7,000 chemicals, including 69 known carcinogens. Smoking damages lung cilia, leading to chronic coughing and impaired lung function. It also weakens the immune system, making smokers more susceptible to infections. Young people are particularly at risk, as smoking can stunt lung development. Long-term smoking results in irreversible lung damage, emphasizing the importance of never starting smoking.
