Currently sick with bronchitis. recently quit smoking. smoked 25 yrs. the bronchitis seems to be pulling a ton o black sputum up. how much is normal?

Great you quit: Years of smoking can beat down tiny hairs on cells that move mucus up and out of your lungs. When some people quit smoking, some of these cells start working better and can get rid of some of the gunk that was in your lungs. This can cause a temp. increase in phlegm. But, black sputum is not normal and a sample should interest your Dr., maybe for tests.

? 25 years worth. In: medical school gross anatomy lab, some had bodies donated by people who had smoked. Seeing either outer or inner lungs the difference (vs. non-smokers) was blatantly obvious. Non-smoker lungs (despite no blood&embalming fluid) looked similar to other organ tissues. But not smokers; Their lungs looked like coal from all the microscopic inhaled & retained smoke particles.
