Welcome to the ehealthforum and I am glad to help you out.
Given your history of smoking, it looks like hemoptysis which is expectoration (coughing up) of blood or of blood-stained sputum from the bronchi, larynx, trachea, or lungs. You need to get a CT scan of the lungs at the earliest to rule out any lung malignancy.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
