<human>: I've heard a lot about the dangers of smoking cigarettes. Is it really that bad for me?
<bot>: Yes, it is. Smoking cigarettes can cause serious health problems like lung cancer and heart disease. It can also lead to other illnesses like COPD (Chronic Obstructive Pulmonary Disease) and emphysema. In addition, smoking can increase your risk of stroke, high blood pressure, and diabetes.
