Cameron Douglas entered the plea Wednesday in Manhattan federal court. The son of the Oscar-winning actor was arrested in July 2008 at a Manhattan hotel.

He was originally put under house arrest. But he was thrown in jail after his girlfriend allegedly tried to smuggle heroin to him in an electric toothbrush.
