Phillip Seymour Hoffman treated for heroin abuse after 23 years of sobriety

After 23 years of sobriety, Phillip Seymour Hoffman relapsed into substance abuse, according to the New York Daily News.

A year later, he checked himself in to a 10-day detox in rehab. The abuse started with prescription drugs and escalated to snorting heroin, he told TMZ.

The heroin use only lasted a week, Hoffman said. He checked out of the 10-day stint on Friday.

The "Capote" Oscar-winner is clean again and has returned to a movie set in Europe.
