The relationship between trauma and substance use: analysing the link between early trauma and later addiction

Abstract

This literature-based dissertation explores the complex relationship between adverse childhood experiences (ACEs) and substance use disorders, with a focus on how the adversities experienced in early life can shape the patterns of substance use in later life. It provides a clear insight into the link between trauma and substance abuse. The aim of this dissertation is to explore how early trauma contributes to substance use disorders, emphasising the role of social care, coping strategies, and the environment in shaping the outcomes. Research found that individuals who experienced adversity in early childhood are at an increased risk of developing substance use disorders in later life. The severity of this can be influenced by support systems, skills and coping strategies. This review examines key theories such as Bowlby’s attachment theory and the self-medication hypothesis, evaluating how these frameworks can inform treatment and interventions. This study examines existing policies and strategies and identifies gaps within trauma informed care and the integration of substance use treatment. Findings emphasise the requirement for coordinated care that takes a holistic approach. Through the collaboration of social care providers, mental health professionals, and healthcare providers, professionals are able to address the complex needs of individuals impacted by both ACEs and SUDs.
