The present paper is called "Addiction and Trauma - Trauma as the Origin of subsequent Alcohol Dependence". It elaborates on the link between traumatic life experiences and later alcohol addiction. After a detailed theoretical discussion of the relevant concepts, the work shows the association between trauma and addiction by using scientific studies. Furthermore, the focus is especially placed on issues such as violence experiences, re-victimisation, self-medication with addictive drugs, dependence and social work as well as therapeutic measures. Thus, the sum of different experiences of life stimulating addictive behaviour and the possibilities of reactions thereon can be understood as the core of the work.
