Former NFL star Ricky Williams shed light on what was happening behind the scenes in the league as guys self-medicated to help diminish the pain they felt from playing football.

Williams, who played for the Miami Dolphins, New Orleans Saints and Baltimore Ravens before calling it a career, was suspended for violating the league’s substance abuse policy multiple times for testing positive for marijuana. 

On Monday, he told USA Today’s "Sports Seriously" show what other guys were doing to treat themselves.

"I played a long time ago, and I played for a long time. So things have changed a lot when I first got into the league," Williams said.

"My rookie year, a Hall of Fame player on the team, he’s in the Hall of Fame now, invited me over to his house and he gave me the speech about how to take care of yourself in the NFL. And he pulled out some cannabis, crushed it up, split a blunt, opened it up, put the cannabis in there, took a Vicodin, crushed it up, sprinkled the Vico in there, rolled up the blunt and passed it to me. That was a vet, teaching me as a rookie, how to take care of myself in the NFL."

Williams entered the league in 1999 after the Saints took him No. 5 overall and gave up to the then-Washington Redskins several picks to move up to get him.

It was not clear who Williams was talking about in that story. He told another one about his final year in the NFL when he was with the Ravens.

"My last year in the NFL, I was playing for the Ravens. And one point we were in the playoffs, and I was leaving the facility and there were guys coming in with a plate full of ‘brownies,’" he said. "They [were] going to go watch film, so yeah…

"And now, because it’s more legal, it’s to the point, why wouldn’t you [use it] if you’re in the NFL?"
