Ask most people in long-term recovery when their substance use actually started making sense to them, and a striking number will point back to something that happened before the addiction: a loss, an assault, combat, a chaotic childhood, an accident. Trauma and addiction show up together often enough that treating one without addressing the other tends to explain why so many people cycle through treatment and relapse anyway.

Here’s why the connection matters clinically, not just narratively, and what treating both actually looks like.

The Real Connection Between Trauma and Substance Use

Trauma can change how the brain and nervous system respond to stress. After trauma, the body may remain on high alert long after the danger has passed. Some people experience hypervigilance, while others feel emotionally numb or disconnected. Some move unpredictably between both states.

Substances can provide temporary relief from these symptoms. Alcohol may quiet an overactive nervous system, while opioids can numb emotional pain. Stimulants may temporarily counter the exhaustion or emotional flatness that sometimes follows trauma.

These patterns often develop because the nervous system is searching for relief from overwhelming emotions and physical responses. Substances may provide that relief temporarily, which can reinforce continued use. Lasting recovery requires more than stopping substance use. Treatment should also address the trauma, triggers, and emotional distress that contributed to substance use in the first place.

Why Treating Only the Addiction Often Doesn’t Hold

Traditional addiction treatment that focuses solely on the substance, without addressing underlying trauma, frequently produces a familiar pattern: someone achieves sobriety, feels stable for a period, and then relapses when a stressor triggers the unresolved trauma response the substance used to manage. Without the substance, the nervous system has to find another way to handle that response, and if trauma hasn’t been addressed, there often isn’t one yet.

This is part of why relapse gets misread as a failure of commitment. More often, it’s a sign that the underlying driver was never actually treated, only the symptom on top of it.

Why Treating Only the Trauma Doesn’t Work Either

The reverse is also true. Trauma therapy alone, without addressing active substance use, runs into a different problem: many trauma-processing approaches require a level of nervous system stability and emotional tolerance that active substance use disrupts. Some trauma therapies can even be destabilizing if someone doesn’t yet have the coping skills to manage what surfaces, which can inadvertently increase the urge to use as a way to cope with what’s been stirred up.

This is why sequencing and integration matter as much as the content of either treatment.

What Integrated Treatment Actually Looks Like

Effective treatment for co-occurring trauma and addiction typically follows a structure rather than tackling both simultaneously with equal intensity from day one:

Stabilization First

Early treatment focuses on physical safety, reducing acute substance use risk, and building basic coping skills, distress tolerance, emotion regulation, and grounding techniques, before trauma processing begins in depth. This is where approaches like dialectical behavior therapy are often introduced, since DBT’s skills training gives someone tools to tolerate difficult emotional states without the substance, which trauma work will eventually stir up more directly.

Trauma Processing, Once There’s a Foundation

Once someone develops enough stability and coping skills, therapy can begin addressing the trauma more directly. Treatment may include trauma-focused cognitive behavioral therapy, EMDR, or somatic approaches. The right approach depends on the person’s needs, comfort level, and available treatment options.

Ongoing Integration

As trauma processing continues, treatment increasingly focuses on integrating what’s been addressed into daily life, relationships, and long-term relapse prevention, recognizing that the two threads (trauma and substance use) will continue to interact well beyond formal treatment.

Why This Matters When Choosing a Treatment Program

If trauma is part of the picture, and for a substantial portion of people in addiction treatment, it is, a program that only addresses substance use is treating half the problem. Questions worth asking a potential treatment provider include whether trauma is assessed as part of intake, whether clinicians are trained in trauma-informed care, and whether the program has a structured way of sequencing stabilization and trauma work rather than doing neither, or doing both without the necessary groundwork.

Not everyone with a substance use disorder has significant trauma history, and not every co-occurring trauma requires intensive trauma-focused therapy during early treatment. But when trauma is present and goes unaddressed, it tends to resurface, often at exactly the moment sobriety starts to feel stable.

If You Recognize This Pattern

If past treatment focused only on substance use, it may have missed an important part of recovery. Repeated relapses can sometimes follow the same underlying emotional or behavioral patterns. Unaddressed trauma may also continue to influence substance use and increase the risk of relapse.

Before starting treatment again, discuss these patterns directly with a provider. A thorough clinical assessment should explore both your substance use and trauma history. This broader picture helps clinicians create a treatment plan that addresses the factors driving substance use.

Redemption’s outpatient programs combine trauma-informed care with DBT and other evidence-based therapies. Treatment addresses the underlying factors contributing to addiction, not just the substance use itself.
