Michael Douglas' son, Cameron Douglas, was released from prison after serving seven years for possession of heroin and selling methamphetamine in 2010, according to E! News.
Cameron, now 37, was originally sentenced to five years in prison, but that sentence was extended when he admitted to smuggling drugs into prison.
He was scheduled to be released in 2018, but according to E! News, Cameron is now living in a halfway house in Brooklyn.
Cameron's father visited him regularly throughout his time in prison.
Michael Douglas has been outspoken about his disappointment in the prison system, according to People magazine.
"I see him twice a month now because he's incarcerated closer to our home," Michael Douglas told People magazine. "He's a drug addict, but he's done more than his fair share of time for it."
Cameron has also shared about his time behind bars. He wrote an open letter, which was published in the Huffington Post in 2013, about the experience.
In that letter, Cameron questioned why non-violent drug addicts are punished by serving a prison sentence.
"This outdated system pays little, if any, concern to the disease of addiction, and instead punishes it more harshly than many violent crimes. And even more exasperating is that many of the people responsible for this tragedy disregard documented medical research and the reality of our country's unsustainable prison overpopulation," Cameron wrote.
