An Australian Doctor Who looked after Survivor contestants and has been hired by film and TV companies to work on other productions has admitted buying pharmaceutical cocaine for his personal use, the New York Post reported today. Dr. Adrian Cohen of Sydney is also being investigated for allegedly using patients' names to write prescriptions for cocaine that he used himself and selling some of the drugs on the sets of TV shows. "I have admitted it was inappropriate," Cohen told the Post. "We made money from it, [but] I certainly didn't make myself rich by doing it."
