What things can happen to your body if you smoke too much?

Smoking too much can lead to a variety of serious health issues, including lung cancer, chronic obstructive pulmonary disease (COPD), and Heart disease. It damages the respiratory system, leading to chronic cough and diminished lung function. Additionally, smoking increases the risk of stroke and can weaken the immune system, making the body more susceptible to infections. Long-term smoking can also cause premature aging and negatively affect oral health.
