A psychiatrist who treated Anna Nicole Smith for drug dependency during her pregnancy said she tried to set up a program to wean her off prescription painkillers but found the celebrity model uncooperative and hostile during her stay in the hospital. Dr. Nathalie Maullin was to continue her testimony Tuesday as prosecutors sought to show that the celebrity model was addicted to painkillers supplied by defendants in a drug case. In her testimony Monday, Maullin described her contact with Smith when she checked into Cedars-Sinai Medical Center in April 2006, pregnant and in apparent withdrawal from pain and anti-anxiety medications. She said Smith had decided to “go cold turkey” and stop all drugs when she became pregnant, resulting in withdrawal. Maullin said she suggested a new regimen including hypnosis and acupuncture but Smith wasn't interested.
