Nah don't do it with joints. What you do is line the inner side of a blunt with a slight layer of honey. Roll blunt. Put blunt in freezer for 30min to an hour. When you smoke, it will burn extremely slowly...I've had blunts to the head go for way longer than an hour doing this. You can also put the honey on the outside after you roll it, but it can get messy that way.
