N. A third-generation blunt, having nothing to do with tediously stuffing an unbroken blunt wrap full of chronic. To make a grandfather blunt, first one must begin smoking first-generation ("normal") blunts and harvesting roaches. After harvesting enough 'resinated' weed from those roaches to roll another blunt, one would twist up with it, creating a second-generation blunt. One would smoke the second-generation blunt and save the roach, then repeat the process with enough second-generation blunts to roll another blunt. Once this final blunt is rolled, one has a grandfather, or third-generation blunt.
"If it takes the roaches of ten blunts to make a second-generation blunt, and the roaches of ten of those to make a third-generation blunt, then this grandfather blunt we are smoking required the smoking of 110 blunts to create."
"Wow, I'm getting really high."
