MICHAEL Douglas thinks prison will be a "really good learning experience" for his drug-prone son.
Cameron Douglas was sentenced to five years in jail last month after pleading guilty to dealing in methamphetamine and cocaine - and now the Wall Street: Money Never Sleeps Hollywood star wants his family to move on with their lives.
Michael told New York magazine: "The things that are going on with Cameron are done with now. He's gotten sentenced, so the tough part was the year before."
Cameron, 31, was recently moved to a minimum-security prison camp in Lewisburg, Philadelphia, after being held at Manhattan's Metropolitan Correctional Center since his arrest last August.
Michael recently said he believes prison will save his son's life.
The 65-year-old star thinks the sentence will finally help Cameron overcome his addiction problems and allow him to make a "fresh start" when he is released.
Michael said: "My son has not been sober for this length of time since he was 13 years old.
"So he was going to be dead or somebody was going to kill him, and I think he has a chance to start a new life and he knows that." - Bang
