The new documentary, How to make money selling drugs, is getting rave reviews for unapologetically delving into the world of drug dealing. In the film, drug dealers and users give a “no-holds-bars” glance into this billion dollar, life threatening industry; one such user is rapper Eminem.

According to the New York Daily News, the popular musician he entered rehab in 2005 having had a sleeping pill addiction. He admits in the film that at one point, he was taking up to 20 Vicodin a day. The 40-year-old shares that because pills were his drug of chose, he didn’t believe he had a problem.

"I don't know what point exactly it started to be a problem. I just remember liking it more and more," he explained.

According to Us Weekly, the rapper (real name, Marshall Mathers) had a brush with death that was never reported in the media. The incident landed him in the hospital and had he been brought in “about two hours later, I would have died,” he says in the film. “My organs were shutting down. My liver, kidneys, everything. They were gonna have to put me on dialysis, they didn’t think I was gonna make it."

Through it all, Mathers has found that there is light at the end of the tunnel. "It's been a learning process. I'm growing,” he explains. “I just couldn't believe that anybody could be naturally happy or naturally function or be just enjoying life in general without being on something. So I would say to anybody, 'It does get better.' You know, it just does."
