best way to do it would be to begin by tearing off the filter. then work the cig in your hands/fingers trying to make it looser. if you have tweesers try pulling the tobacco out. if not, use something to poke it out. with tweesers this can be done in like 5 minutes. but if you ahve no tweesers it can take a while. so once you empty the cig out, pinch one end and begin to fill the joint with finley ground bud and pack it down in there, with a pen or something, not too tight but tight enough to make it firm.
