Welcome to Pathways of Public Science: Interviews Documenting the History of Research on Addiction and Psychoactive Substance Use Disorders Basic and clinical research on substance use disorders has been a public science since its inception in the 1920s. Historians Nancy D. Campbell and Joseph Spillane interviewed dozens of scientists and clinicians who identified as contributors to the science of substance use disorders. These oral history interviews offer a roadmap to the field as it was experienced and remembered in 2003-2008. The selection of interviewees was made within the context of annual meetings of the College on Problems of Drug Dependence, with additional site visits to important laboratories such as the Treatment Research Institute in Philadelphia (now PHMC Research and Evaluation Group)) and Virginia Commonwealth University. All interviews were conducted by Nancy D. Campbell and/or Joseph Spillane, co-PIs on NSF Award 618902, “The Social Organization of a Public Science: Mapping the Changing Topography of Substance Abuse Research.” Our goal is to make these interviews available for purposes of documenting the history and public significance of this multidisciplinary science. Interviewees describe their pathways into science, career milestones, views on drugs, drug policy, human and animal research ethics, and public engagement efforts. Each interview offers a unique window on a scientific life. All were interviewed with fully voluntary informed consent. We offer transcribed and lightly edited interviews as primary sources for understanding the history of the science of substance use disorders. The interviews include expression of conflicting views, values, and priorities. We hope that these will be understood within the social, political, and economic contexts within which they were generated.
