Dear 100 Hour Board,
Can marijuana be used as a pizza topping?
-THAS NOT OREGANO
Google indicates yes.
I Googled your exact question and was rewarded with a plethora of information and recipes.
Everything can be used as a pizza topping. Even I can be used as a pizza topping, but that is called "cannibalism," my dear children, and is in fact frowned upon in most societies.
