hoffman-rehab-230.jpgPhilip Seymour Hoffman has completed 10 days in rehab for snorting heroin.

The Oscar winner told TMZ that he had been clean for 23 years, and added that he began with prescription pills and recently graduated to heroin. Hoffman credits "a great group of friends and family" for assistance in getting the necessary help he required.

In 2006, Hoffman opened up about his prior substance-abuse issues on 60 Minutes, which began shortly after he graduated from New York University. "It was anything I could get my hands on ... I liked it all," he said. "I went [to rehab], I got sober when I was 22 years old. You get panicked... and I got panicked for my life. It really was just that."

The 45-year-old actor is reportedly back at work, shooting his next film project in Europe.
