Hi Nusrath. You would probably need to undergo further diagnostic investigations, like a sputum test, to identify the cause. As you can see from the article above, there are many possible causes of the phlegm. It could be from the nose or from the lower airways and even the lungs. There is no way to say for sure. You should consult with a doctor who can assess you. Once the diagnosis is reached, the appropriate treatment will be then prescribed.

the mucus (mouth) from my chest sometime are in brown or rusty color even if i dont have cough. i do have sinus problem and i dont smoke. It happens rarely. there is also sometime little black particles in the phlegm. what does this means?

“did you know one joint is equivalent in tar to 118 cigarettes?”

Come on misti, never go full retard!

that is 100% false

Hi Kylea. That’s a difficult question to answer. Some people do and some don’t. A similar situation applies to tobacco smoking. Some people will develop lung disease and even cancer sooner than others and there is no specific reason why this happens. There are many factors at play such as how often you smoke, the quantity and the quality of the plant. Nevertheless it is not advisable to continue with this habit.
