CBS News' 48 Hours investigates the often under-regulated world of human medical testing. According to many critics, research subjects can end up in worse condition than before they began. Drug Money: Correspondent Susan Spencer reports on Richard Borison and Bruce Diamond, two men who set up a fake drug testing operation and deceived patients, drug companies and the state of Georgia. Here To Help? Correspondent Erin Moriarty reports on the case of Shalmah Prince, a manic depressive woman who checked herself into a hospital for treatment. Instead of being treated for that condition, she ended up participating in a study of an experimental psychosis drug.
