The sentence was announced by federal Judge Richard Berman in Manhattan. The judge criticized the government for being too lenient on Douglas after he repeatedly violated prison rules by arranging to get drugs. The judge said the violations included four instances in which a lawyer smuggled drugs into prison for Douglas in her bra.

The 32-year-old Douglas asked the judge to give him another chance at treatment. Berman recommended he be sent to a prison facility that can offer him drug treatment and mental health care.

Douglas was first arrested in July 2009 for dealing methamphetamine from a high-end Manhattan hotel.
