Try putting a roach in it - roll a ice of card into a little tube, it'l put a bit of distance between you and the end of the J. I never roll without one.

Also try a hand bong, make a fist, put the joint between your 3rd finger and your ring finger, stick your thumb of the other hand in the bottom to block any air from escaping and inhale through the top, it will also give you a slightly stronger hit
