A judge in Manhattan sentenced Kelly Sott to time served for drug possession. She had pleaded guilty last month.

"I learned a good lesson," Sott told the judge. "I just want to leave all that behind me - the drugs. ... Thank you for giving me a second chance."

Sott's lawyer said her time behind bars had given her a chance to kick a drug habit she picked up amid her distress over losing two friends in the September 11, 2001 terror attacks. As part of her sentence, the judge ordered her to undergo drug treatment and counselling for a year after she returns to her home in Pennsylvania.

Sott was arrested last summer after she was caught trying smuggle heroin to Cameron Douglas, an admitted drug addict and dealer who was under house arrest at the time, inside an electric toothbrush.

The son of the Oscar winner was arrested on July 28 last year at the trendy Hotel Gansevoort as part of a Drug Enforcement Administration investigation.

Investigators say Douglas was paid tens of thousands of dollars for trafficking large amounts of methamphetamine - which he referred to in intercepted phone calls as "pastry" or "bath salts".

Cash and drugs were routinely exchanged from US coast to coast through shippers like FedEx, the court papers said.

He pleaded guilty in January to conspiracy to distribute drugs as part of a deal requiring him to co-operate with an investigation of meth suppliers. He also pleaded guilty to heroin possession - a charge stemming from the toothbrush incident - and will be sentenced next month.

Cameron Douglas has acted in movies including 2003's It Runs In The Family, starring his father and grandfather Kirk Douglas.
