The Connection Between Trauma and Addiction
Trauma and addiction are deeply intertwined, often creating a cycle that feels overwhelming and unbreakable. Yet, understanding this connection is the first step toward healing and recovery. Many individuals struggling with substance use have experienced trauma at some point in their lives—whether it stems from childhood adversity, a sudden loss, or ongoing emotional pain. For many, addiction begins as an attempt to numb that pain, but over time, it only deepens the wounds.
At Dunham House, we recognize that healing from addiction requires addressing the underlying trauma as well. With the right support and understanding, transformation is not only possible but within reach.
What is Trauma? Types and Long-Term Effects
Trauma goes beyond a painful memory—it’s a deeply distressing experience that can reshape how we think, feel, and interact with the world. It leaves lasting imprints on our mental, emotional, and physical well-being. Trauma can take many forms, including:
Acute trauma: A single distressing event, such as an accident, natural disaster, or assault.
Chronic trauma: Ongoing exposure to stressful situations, such as abuse, neglect, or living in a high-stress environment.
Complex trauma: Repeated exposure to traumatic events, often in childhood, which deeply affects emotional development and relationships.
Unresolved trauma can lead to anxiety, depression, PTSD, and difficulty forming healthy connections with others. Many who experience trauma struggle to regulate their emotions, leading them to seek relief in harmful ways—including substance use.

Why Trauma Increases the Risk of Addiction
When trauma occurs, the brain undergoes profound changes, altering how we process emotions and respond to stress. The body’s fight-or-flight response is triggered, flooding the system with stress hormones like cortisol. In a healthy system, the body eventually calms down. But for those with unresolved trauma, this stress response remains activated, leading to chronic anxiety, hypervigilance, and emotional instability.
To cope, many turn to substances like alcohol or drugs. This is known as self-medication—using substances to numb emotional pain or regain a sense of control. While substances may provide temporary relief, they ultimately reinforce the cycle of trauma by worsening mental health, increasing dependency, and preventing true healing.
Additionally, studies show that individuals with a history of trauma are at a much higher risk of developing substance use disorders. Research from the National Institute on Drug Abuse highlights that childhood trauma, in particular, significantly increases the likelihood of addiction later in life. The earlier trauma is addressed, the better the outcomes for long-term mental and emotional well-being.

How Trauma Rewires the Brain and Fuels Addiction
Understanding how the brain responds to trauma sheds light on why addiction is so prevalent among trauma survivors. Science shows that trauma rewires the brain, making it more vulnerable to substance use. Key factors include:
Dopamine and the reward system: Trauma can disrupt the brain’s natural production of dopamine, the chemical responsible for pleasure and motivation. Substances artificially boost dopamine, providing a temporary “high” that the brain begins to crave.
Chronic stress and addiction: Repeated exposure to stress alters the brain’s structure, making it more prone to impulsive behaviors, cravings, and dependency.
Fight-or-flight mode: Trauma keeps the body in survival mode, making it difficult to regulate emotions and make rational decisions, which increases the risk of substance abuse.
Additionally, trauma-related changes in brain function can lead to an impaired ability to process emotions effectively. Many individuals who experience trauma struggle with emotional dysregulation, meaning they find it challenging to cope with negative emotions in a healthy way. As a result, substances become a form of escape, perpetuating the cycle of addiction.
How to Heal Trauma and Overcome Addiction: Breaking the Cycle
To achieve lasting recovery, it’s crucial to address both addiction and the underlying trauma. Healing one without the other often leaves the root cause unresolved. Traditional approaches that focus solely on substance use frequently fall short because they don’t tackle the deeper wounds. Instead, trauma-informed care is essential.
What is Trauma-Informed Care?
Trauma-informed care ensures that treatment environments are safe, supportive, and empowering, minimizing re-traumatization and promoting long-term recovery. It acknowledges the impact of trauma and integrates practices that foster healing.
Some of the most effective therapies for healing trauma and addiction include:
Eye Movement Desensitization and Reprocessing (EMDR): Helps process traumatic memories in a safe and structured way.
Cognitive Behavioral Therapy (CBT): Identifies negative thought patterns and replaces them with healthier coping mechanisms.
Mindfulness and meditation: Teaches emotional regulation and stress reduction without relying on substances.
Somatic Therapy: Focuses on reconnecting the body and mind, helping individuals process trauma stored in the nervous system.
Group Therapy: Provides a sense of community and shared experience, reducing feelings of isolation that often accompany both trauma and addiction.
