Now, the reason you cough is obvious. Inhaling hot, iritating smoke into your lungs. But what I would like to know, is why people say "the more you cough the higher you get". I beleive in this, because it happens whenever I smoke. But, why does it happen? Can some of you experts explain this, or maybe direct me to a thread that will explain this? I didn't find anything when using the search button, thanks.
