When we think about addiction, we often focus on the substance or behavior itself—alcohol, drugs, gambling, or compulsive shopping. But addiction is rarely just about the substance; it’s about the why. Why does someone feel the need to escape, numb, or seek control? One of the most overlooked answers is unresolved trauma. Trauma and Addiction are often linked together but many people struggling with addiction are unable to have success in recovery without addressing their traumas.
Understanding Trauma: “Big T” vs. “Little t“
Trauma comes in many forms, and not all traumatic experiences are the same. Experts often distinguish between Big T Trauma and Little t Trauma to better understand the impact of different experiences:
- Big T Trauma refers to major life-threatening or deeply distressing events, such as physical or sexual abuse, violent assaults, natural disasters, combat exposure, or severe accidents. These events often result in post-traumatic stress disorder (PTSD) and can have lasting emotional and physiological effects.
- Little t Trauma refers to less obvious but still deeply impactful experiences, such as chronic stress, emotional neglect, bullying, parental divorce, or feelings of abandonment. While these experiences might not seem catastrophic at first glance, they accumulate over time and can significantly affect a person’s mental health.
Both types of trauma can create emotional wounds that, if left unaddressed, increase vulnerability to addiction as a coping mechanism.
How Trauma Rewires the Brain and Leads to Addiction
Trauma and the Brain’s Stress Response
When someone experiences trauma, their brain shifts into survival mode. The amygdala, the brain’s fear center, becomes overactive, while the prefrontal cortex (which helps with reasoning and impulse control) becomes less effective. This dysregulation makes it difficult for a person to calm down, process emotions, and feel safe.
For someone with unresolved trauma, the brain stays in a heightened state of stress, leading to chronic anxiety, hypervigilance, or emotional numbness. To escape these uncomfortable states, many turn to substances or compulsive behaviors that provide temporary relief.
Self-Medication for Emotional Pain
Trauma survivors often feel overwhelming emotions—guilt, shame, sadness, or fear. Substances like alcohol and drugs artificially flood the brain with dopamine, creating a short-lived sense of relief or pleasure. Unfortunately, over time, the brain becomes reliant on these substances just to feel normal, leading to dependence and addiction.
Addiction and Emotional Dysregulation
Unresolved trauma makes it difficult for people to regulate emotions. This can lead to impulsive behaviors, unhealthy relationships, and a constant search for external validation or relief. Since substances offer an immediate escape, they become an easy but dangerous coping strategy. People often think of addiction as substance abuse or alcohol abuse; however, many people have process addictions.
Process addictions, also known as behavioral addictions, involve compulsive engagement in activities that provide a sense of pleasure or relief but ultimately lead to negative consequences. Here are five common types:
- Gambling Addiction – An uncontrollable urge to gamble despite harmful consequences, often leading to financial, emotional, and relational distress.
- Sex and Pornography Addiction – A compulsive engagement in sexual behaviors or pornography use that interferes with daily life, relationships, and mental well-being.
- Food Addiction – An unhealthy relationship with food, characterized by compulsive overeating, binge eating, or emotional eating to cope with stress, sadness, or trauma.
- Shopping Addiction (Compulsive Buying Disorder) – An obsession with shopping that leads to financial problems, emotional distress, and a cycle of short-term pleasure followed by guilt or regret.
- Internet and Social Media Addiction – Excessive use of social media, gaming, or online activities that interferes with real-life responsibilities, relationships, and mental health.
Each of these process addictions shares similarities with substance addiction, as they trigger dopamine release in the brain and create cycles of craving, temporary relief, and negative consequences.
Shame and Isolation Fuel the Cycle
One of the biggest hidden effects of trauma is shame. Many trauma survivors blame themselves for what happened or feel weak for struggling. This self-blame leads to isolation, which is a major risk factor for addiction. Without a healthy support system, people often turn to substances for comfort, reinforcing the addiction cycle. Trauma and addiction are deeply rooted in shame. Working with a licensed counselor will be helpful to resolve this connection to shame.
Healing Trauma to Overcome Addiction
If unresolved trauma is at the root of addiction, then true healing comes from addressing the trauma itself, not just the substance use. Here’s how:
- Trauma-Informed Therapy: Therapies like Eye Movement Desensitization and Reprocessing (EMDR), Cognitive Behavioral Therapy (CBT), and somatic experiencing help individuals process trauma and addiction in a way that reduces its emotional hold.
- Developing Healthy Coping Strategies: Learning mindfulness, meditation, journaling, or engaging in supportive communities can help regulate emotions without relying on substances.
- Rebuilding Connection: Trauma often isolates people, and addiction thrives in isolation. Seeking therapy, support groups, or trusted relationships can help rebuild a sense of safety and belonging.
There is Hope for Healing Your Trauma Responses
Addiction isn’t about a lack of willpower or moral failing. It’s often a response to deep, unresolved pain. By understanding how trauma and addiction —both Big T and Little t—affects the brain and emotions, we can shift the focus from judgment to healing. If you or someone you know is struggling with addiction, addressing the underlying trauma can be the key to breaking free.
Healing is possible. It starts with recognizing the pain, seeking help, and taking small, brave steps toward recovery.
