Ive had this problem before man, it was really wierd. It didnt really hurt but it was like i could only inhale half of what i normally do, i told my friends about it and jokingly they said to smoke some dank and itll go away... well i smoked the dank alright, but still had the problem.

it went away in a day or 2 though, so if you are experiencing what happened to me, youll be fine in a day or so
