Eminem has ended his silence on his drug-addicted past. The rapper participated in the newly released documentary How to Make Money Selling Drugs giving a testimonial of his own experiences with drugs. While the documentary is controversial, Eminem’s story is cautionary.

The rapper initially denied his addiction, arguing that he wasn’t using hard drugs like crack and, therefore, didn’t have a problem. He entered rehab the first time in 2005 to deal with an addiction to sleeping pills, but quickly relapsed. He became addicted to Xanax, Vicodin and Valium and overdosed in December 2007.

“My organs were shutting down. My liver, kidneys, everything,” explained Eminem, “They were gonna have to put me on dialysis, they didn’t think I was gonna make it.”

Eminem recovered slowly, undergoing therapy for speech and basic motor skills and has been fighting his addiction ever since, mostly to ensure that he can be there for his three children.
