Michael Douglas' son pleads guilty to drug possession

(CBS/AP) Cameron Douglas has plead guilty to possessing illegal drugs while in prison. Michael Douglas' son is currently in custody for charges stemming from possession of methamphetamines with the intent to distribute.

"God knows I'm sorry about this situation," the 32-year-old told the judge during the proceedings.

Michael Douglas, who did not appear in court, issued a statement saying that his son's new offense was for a smaller amount of drugs.

"Cameron accepts full responsibility for his conduct," his father said. "While he has made much progress, he is still not cured. Most people and their families are able to address this illness privately and outside the spotlight. Unfortunately this has not been possible here -- for reasons completely outside of his control. He thanks those that have rooted for his recovery and looks forward to the day when he will not disappoint."

Two weeks ago, Cameron Douglas had served as a government witness against a co-defendant facing drug charges. It was part of his plea bargain to reduce his original sentence to five years instead of a maximum of 10.

Authorities found items testing positive for cocaine and heroin in his cell. People magazine reported that according to a court transcript, Assistant U.S. Attorney Justin Anderson said one of the substances tested positive for methadone, which he described as "something that people take when they're coming off a heroin addiction in order to facilitate the withdrawal."

The charge can carry up to 20 years in prison, but prosecutors are recommending up to 18 months in custody. His sentencing is set for Dec. 21.
