Hard Cough

I smoke, but only about 10 cigarettes a day, and when i breath out (in the same way you do for an asthma test), and when i do you can hear this horrible gargling noise deep in my throat and lungs. I don’t want any useless advice on how smoking is bad for you, i am fully aware of it! But if anyone has a simple cure for it then i would be very grateful! Thanks.

first you need antibiotics , you have a chest infection ,
