unless u have a PhD (no not pretty huge d***) u cant tell. take a break from the blunts if that is what u usually smoke... when i was younger me and the homies would love to smoke blunts... but after a while the throat gets irritated cause blunts are thick and usually soaked in some flavored solution(depends what blunts) but still blunt paper is thick. do some pipe hits or joints. even try to cut back a little so ur throat can heal.
