i was having the same problem, what i started doing was taking a big paper clip, unfolding it til its straight and then putting it inside the joint horizontally when i rolled it. when you finish rolling just pull the paper clip straight out. there is now a small airway through the joint that will allow air through. Also did the same thing for blunts when i used to smoke them all the time, the inside of a ball point pen wil work too for blunts.creates a nice airway:thumbsup:
