'Although those afflicted are at high risk of being discriminated against, substance use disorders have been neglected by stigma research for far too long. It is to the editors' credit that they have gathered an impressive group of scholars and people with lived experience, who provide a broad and in-depth analysis of substance use stigma, and how to overcome it.' Matthias C. Angermeyer, Emeritus Professor of Psychiatry, University of Leipzig, Germany
