Former NFL running Ricky Williams has never been shy about his marijuana use.

But one of his ex-teammates is shedding some light on how prevalent Williams' smoking was. While appearing on WQAM radio in Miami, former Dolphins linebacker Channing Crowder discussed Williams' use before games.

"Remember that Buffalo game, the 200-yard game?" Crowder said. "Smoked the night before. Talk to Ricky. He was doing it, that's what he did. Ricky has social anxiety, and he smoked weed. Ricky's marijuana didn't affect the team until he got caught smoking. . . . Him smoking weed, sitting at his house smoking weed, didn't affect anybody but Ricky. He got high and then he sobered up and then he went to practice the next day."

Williams tested positive for marijuana multiple times during his 11-year career. He also played for the Baltimore Ravens and the New Orleans Saints during his career and rushed for 10,009 yards and led the league in rushing with 1,853 yards in 2002.
