The clip where he speaks on it is above. From AllHipHop:
On his Shot97 Radio show, Star reveals that Jay Z once sold him cocaine to him back in the 80s.
Star states he’s “not trying to play Jay Z out” by revealing these stories about Jay Z drug past. According to Star, the man with 13 #1 album had a quality product in the 80s, but competition was stiff:
“Back in the late ‘80s, I went to this man on a few occasions, hand-to-hand. He had the good sh*t. Now his sh*t wasn’t as popping as the West Indians over in the 90s and in Flatbush. Them Shower Posse n*ggas must have had that shit shipped in from Columbia or some f*ckin’ where.”
Star does say Jay Z was a generous drug dealer “extended credit to a coke head in the wee hours” when Star was short on payment.
