This anthology provides an overview of the actual impacts of drug addiction and drug substitution, as well as the feedback processes on child development, and offers insight into the severe risks for children stemming from their parents' drug addiction. It demonstrates how the care of drug-affected family systems can be ensured by professional helpers.
