If you burn it you get stoned
Your grandparents.
A crackhead buys crack so he can put it into his pipe and burn it. A John pays so that he can put his pipe into a crack that might burn him.
Because if your burn it, it gets you stoned
The stone to throw the lights out, the flashlight to check if the lights are really out
In potholes.
Pothead plants.
