Reality TV star Jack Osbourne credits drug addiction with turning his life around - because it taught him the value of life.
He says, "I don't regret what happened. In a weird way being an alcoholic and drug addict was probably one of the best things I could have done to myself.
"It made me sort myself out, I was out of control. I was so low the week I checked myself into rehab in Los Angeles. I knew if I was to carry on like that I was going to end up dead."
