An expert witness has withdrawn testimony about one of Anna Nicole Smith's doctors massively increasing her methadone doses.
Dr. James Gagne, testifying for the prosecution on Wednesday in Los Angeles, says he misunderstood records kept by Dr. Sandeep Kapoor.
Gagne says he now believes the methadone prescriptions were not a major issue in the case.
However, the witness stood by earlier testimony that Kapoor gave Smith excessive dosages of opiates and sedatives.
Kapoor is one of three defendants charged with illegally funneling drugs to Smith, who died of an accidental overdose in 2007. All have pleaded not guilty.
