Ricky Williams routinely smoked marijuana on the evening before NFL games, according to former teammate Channing Crowder.

“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.”

NFL players are tested for marijuana just once per year.
