### Patient: Doctor, I have been coughing a lot recently, and I feel like I become excessively angry very quickly. Also, it hurts when I breathe in deeply. What could be the cause of these symptoms?
### Doctor: It seems like you may have a smoking or tobacco addiction. These symptoms can be caused by the irritation and damage that smoking or inhaling tobacco can cause to your respiratory system and overall health. Have you been smoking or using tobacco products?
