I have had a chronic cough since November last year.  Doctors say that he thinks I had whooping cough to begin with that just wasnt treated early enough.  i have tightness of chest, headaches, lethargy, aching joints.  I have been smoking marijuana regularly with a friend and have found out tonight that they had made their bucket with plastic stuck under the cone....I have been breathing burnt plastic for about three months!!!! Is this bad??? Could this be the cause of my cough?
Respected user, HiT hanks for using Chat Doctor.come have evaluated your query thoroughly.* Definitely this will cause chronic cough by injuring your bronchi, alveoli & other tissues of the respiratory tract along with the detrimental effects of Marijuana.* Now as you have become aware about your lungs, it is time to decide to QUIT CONSUMPTION OF ALL ABUSE SUBSTANCES INCLUDING MARIJUANA for rest of the life. Hope this clears your query. Always welcome for any further assistance. Regards dear take care.
