Gordon declined to identify which players allegedly used drugs but said D.J. White and two others still on the team were among those who did not.
Gordon, who left after his freshman season and now starts for the Los Angeles Clippers, said some players' drug use led to friction on the team. Then-coach Kelvin Sampson tried to stop it, Gordon told the newspaper, but Sampson "was just so focused on basketball and winning and everything."
"Sometimes it felt like it wasn't even a real basketball team because of all the turmoil that went on," Gordon said.
Former Indiana guard Adam Ahlfeld confirmed drug use by players. He said he was not involved.
Current coach Tom Crean declined to discuss the issue, citing privacy laws.
Indiana started 17-1 last season, but by February the school bought out Sampson's contract as allegations surfaced about a recruiting scandal involving him. Last month, the NCAA put Indiana on three years' probation for recruiting violations.
