The Associated Press is investigating how the opioid epidemic, once thought to be an American problem, is spreading worldwide. In Australia, reporter Kristen Gelineau spent months trying to get addicts and their families across the country to talk to her—a particularly difficult task because of the stigma around opioid addiction in the country. Those who finally agreed to talk to Gelineau did it for one reason: They wanted others to know about the danger and the pervasiveness of opioid addiction. Gelineau also painstakingly tracked down the role drug companies have played in the crisis in Australia, even as they face scrutiny in the U.S. for their aggressive marketing of opioids.
