Understanding addiction is no longer just about understanding neurons or genes, broken brain functioning, learning or faulty choices. Oliver J. Morgan provides a fresh take on addiction and recovery by presenting a more inclusive framework than traditional understanding. Cutting- edge work in attachment, interpersonal neurobiology and trauma is integrated with ecological-systems thinking to provide a consilient and comprehensive picture of addiction. Humans are born into connection and require nourishing relationships for healthy living. Adversities, however, bring fragmentation and create the conditions for ill health. They create vulnerabilities. In order to cope, individuals can turn to alternatives, “substitute relationships” that ease the pain of disconnection. These can become addictions. Addiction, Attachment, Trauma, and Recovery presents a model, a method and a mandate. This new focus calls for change in the established ways we think and behave about addiction and recovery. It reorients understanding and clinical practice for mental health and addiction counsellors, psychologists and social workers, as well as for addicts and those who love them.
