Migration has not only occurred in large numbers in the history of the Federal Republic of Germany over the past two years but has been a continuous process. All areas of work responsible for the social, psychological-psychotherapeutic, and medical care of individuals are constantly faced with the challenge of ensuring that their services and offerings are equally accessible to newcomers as they are to locals. Are the professional concepts of addiction support suitable for providing adequate care for migrants? What does cultural sensitivity mean? What foundations need to be established for the development of transcultural competencies, for processes of intercultural opening, and for cooperative networking with migrant organizations? This book outlines the discussions surrounding the topics of migration and addiction.
