The office of California Gov. Jerry Brown announced on Thursday the pardon of 91 people, and Downey was among them.
Downey was convicted of felony drug possession in Los Angeles County after he was arrested with cocaine, heroin and a pistol in his vehicle. In 1999, he was sent to prison for nearly a year after violating his probation.
While the pardon does not erase the record of conviction, it restores voting rights and is a public acknowledgement that Downey has demonstrated "exemplary behavior," according to the governor's website.
Congratulations, Robert Downey Jr.! Hopefully his story continues to inspire others struggling with drug and alcohol addiction.
