Slang term for a non-tobacco blunt rolled with that sweet Mary Jane, other wise known as weed. Sometimes used with the slang term factory, meaning; you cant tell the blunt was even split, it looks like a cigar rolled in a factory waiting to be sold at the store.
"Hey Alex you should pick up some sticks from Habib's store and i will twist a factory b-unit."

Cory said to Alex; "boy you best go get them sticks!I want a b-unit!"
