From what I remember its blows with the "s" for h. Last time I got any Chi dope it was from a "rocks or blows" dude who had fire caps. This was like 3-4 years ago as I met the dude who copped Chi dope in edwardsville where I went for university. Every holiday break he'd bring down some straight fire. Then he got expelled when his roommate found his ass OD'd in the bathroom with blood all over cuz he smashed his head on the sink when he fell :/ he's still alive I believe though, hopefully cuz as I said I ain't seen him in some years.
