KNOXVILLE, Tenn. (AP) - A nurse who was a patient at a now-defunct Maryville pain clinic has testified she lost everything important to her and became dependent on narcotics prescribed for her.

According to The Knoxville News Sentinel (http://bit.ly/QaUiEo ), Kristi Teffeteller testified Tuesday in Knoxville federal court, saying she received massive dosages of opiates with little, if any, medical examination at Maryville Pain Management Consultants.

Federal drug agents shut down the clinic in December 2010 and prosecutors claim owner Tamral "Tammy" Guzman was raking in cash payments of up to $28,000 per day to prescribe powerful painkillers.

Guzman said she put her trust in nurse practitioners she employed and the doctors who supervised them.

Guzman is charged with operating a pill mill, trading cash for prescriptions and, eventually, for the painkillers themselves.
