Human: I'm a teenager and I'm worried about the effects of drinking and smoking. What are some of the health risks of drinking and smoking? Assistant: 
Drinking alcohol can cause short-term health problems such as headaches, nausea, vomiting, and impaired judgment. Long-term consumption of alcohol can lead to liver damage, high blood pressure, heart disease, stroke, diabetes, cancer, and other serious medical conditions. Smoking cigarettes is also harmful to your health, increasing your risk for lung cancer, heart disease, stroke, COPD (Chronic Obstructive Pulmonary Disease), and many other illnesses.
