'The Osbournes' was using the painkiller OxyContin...

JACK OSBOURNE admitted himself into rehab because of his use of the painkiller OXYCONTIN, he has said.

Jack checked himself into a Californian hospital earlier this year. In his first interview since leaving the hospital, the ’Osbournes’ star has revealed he was taking the painkiller OxyContin and it became too much for him.

“I took myself out of the picture for a second and I looked around at every single person in the room, at who they were, how old they were and what they had going on in their lives,” Osbourne told MTV of his time in rehab. “A lot of them were near 30, unemployed, living off their parents. There were heroin addicts, there were the world’s biggest couch potatoes. And it was like, ‘I don’t want to be like that. I don’t want my life to be controlled by a drug.'”

Jack also revealed how he told his family he needed help. He added: “I want to be in control of my life. I was really loaded and I just sat on my mom’s bed and I just said, ‘I am going to go pack my bags, I’m ready to go. I want to go, I need to go.'”
