Hi, i am richard and i smoke hookah every week. Hookah is a pipe with tabacco. In the past summer, i smoked everyday with my friends. One day i started to get phlegm and it wouldnt go away. My first thought was it was a cold but i still have it and it has been almost 5 months. Does anyone know something i would have? I am 20 years old and in college. Please let me know.
