duff

The stuff left on the bottom of your weed bags. All the stems, crystals, and leafs. Often used as a cheaper alternative to buds in baking. Though often mistaken as good, and used in joints and bowls. Known to be sold for as cheap as 30-40 dollars an ounce.

Hey bro, got any of that duff? I need to make another's batch of weed brownies.
