Is it back to charging motherfuckers 4 for an O?
I don't know

from Evidence – It Wasn't Me Lyrics on Rap Genius

Meaning

“4 for an O” = $400 for an ounce of weed. In reference to the previous line, if the weed shops are closed, supply goes down, demand stays the same, and the price of an ounce of weed goes back up to $400, which would be a lot in a state that has a marijuana economy as large as Cali’s.
Average price for an ounce of high quality weed in CA: $305.18

An ounce of some pretty good nugs
