Grandparent Joint

Save the roaches from your joints and combine the resonated pot into a new (more potent) joint. If planned correctly, this technique can be repeated endlessly, producing high-potency grandparent joints and even great-grandparent joints.

"Looks like we've got enough here for a Grandparent joint, anyone down?"

"I have been saving the great-grandparent joint of last summer for my backpacking trip."
