### input:
After 13 years of smoking, my boyfriend has just recently quit cigarettes.  However, he has replaced them with black and milds which is a type of cigarillo.  He was up to smoking about 20 cigarettes a day before he quit and now inhales about 3 black and milds a day, he will not smoke the entire cigarillo in on sitting he usually puffs on it a few times, puts it out and in about an hour repeats the process.  It adds up to about 20 smoke breaks a day, so clearly he has replaced on habit with other.  I wanted to provide you with some background information but here is where my problem lies.  For the last month he has been coughing nonstop and sometimes the coughing spells are more violent than others.  It is usually a dry cough, but sometimes he does spit up black stuff.   I became increasing worried last night when the coughing prevented from being able to sleep.  He also began wheezing and complaining of shortness of breath.  He refused to go to the doctor and still does, against my better judgment I allowed him to use my albuterol inhaler, I am an asthmatic, to provide him with some relief.  He seems to be doing okay today.  He has been trying to convince me that this normal for a person who has just quit smoking.  Am I panicking or could something really be wrong?

### output:

Hi, as it is a normal symptom of wheezing, shortness of breath and cough. The cough is called as a smokers cough. Due to the physiological changes appearing in the lungs there will be weeks in the lung tissue leading to the wheezing and shortness of breath. Also, the weakness of Respiratory muscle will not produce effective coughing to expel the sputum. Performing regular breathing exercises there are various types of it will help improve the cellular functioning and also improve the strength in the respiratory muscles. Also, doing some regular cardio respiratory training slowly will improve the overall health and reduce the toxic levels in the body with the grace of God I wish a good health
