When you get really desperate due to not having bud and pack a cone with the black, burnt substance (resin) found in and around the cp and stem. Resin must be dried out for approximately 2 hours before smoking it. You may also need a stoke (such as a thin stick) as resin is much harder and more heinous to punch. A common way of packing a resin cone is to place a small amount of bacci in the cp and put the resin on top of the bacci.
Louis: FUCK, we got no more uds!
harry: Looks like were having resin cones dude.
