A grandaddy joint is a marijuana cigarette produced during times of desperation, made of many already-smoked spliff ends or roaches from previous smoking sessions. It is called a grandaddy because it is an old
ass decrepit and sour joint reminiscent of the smell of elderly
people, these spliffs are particularly difficult to inhale and are almost unenjoyable to smoke.
Grandaddy ingredients may include the following:
weed, hash, stale tobacco, dust, keef, dead
skin flakes, and any other dirty ashtray contents.

"you know times are tough when you
don't even have endies for a grandaddy"
