Cameron Douglas was arrested last August (09) following a drugs raid on his room at Manhattan’s Hotel Gansevoort.
He pleaded guilty to one count of possession with intent to distribute a controlled substance and one count of possession of heroin in January (10).
The It Runs in the Family star was originally put under house arrest at his mother’s Manhattan address.
However, the 31 year old was thrown back behind bars after he allegedly asked his girlfriend to smuggle heroin to him in an electric toothbrush.
Cameron returned to New York’s Federal Court on Thursday (25Feb10), when his lawyer entered a request for bail so his client could be transferred to a rehabilitation centre to treat his drug addiction.
But the judge denied Cameron’s appeal, ruling he was more likely to relapse if he was let out, reports TMZ.com.
Douglas’ son is due back in court in April (10). If convicted, he faces a minimum 10-year prison sentence.
On Monday (22Feb10), his girlfriend Kelly Sott pleaded guilty to a misdemeanour charge of possessing methamphetamine, which carries a maximum one-year prison sentence.
