It's likely: Is the cough productive? If you are bringing up phlegm (sputum), it is likely to be infection, the chances of which are greatly increased by smoking. If the sputum is yellow or green, or foul smelling, it may be a bacterial infection, although without fever that is less likely. Cut down or stop smoking, at least until it clears, and consider permanent cessation. Your lungs are sending u message.
