it is really weird for me sometimes i can smoke so much without coughing, but every once in awhile if it is my first hit of the day, but not everytime, ill get into these coughing fits where i cough for honestly five minutes straight and people think im going to pass out, like i cough so much i sweat. but then other times i can take huge hits from bongs or anything else and dont feel a thing as far as a need to cough.
