What Is Trauma? The Trauma-Addiction Connection
Trauma is the lasting psychological and physiological imprint left by an overwhelming, frightening, or distressing experience — one that can override the nervous system’s ability to cope. At Holina Rehab we see it constantly alongside addiction: unresolved trauma often drives the substance use it becomes entangled with, which is why treating one without the other rarely produces lasting recovery.

What Is Trauma?
Trauma is an emotional and physiological response to a distressing event — an accident, crime, natural disaster, physical or emotional abuse, neglect, witnessing or experiencing violence, the death of a loved one, or war. Immediately after the event, shock and denial are common. Over time, unresolved trauma can produce unpredictable emotions, flashbacks, strained relationships, and physical symptoms such as headaches or nausea — and for many people, it becomes a driving force behind addictive behaviour.
Trauma can arise from a single incident or from ongoing experiences over an extended period, and its impact can last a lifetime, varying in severity from person to person. What makes an event traumatic is not the event itself but its lasting effect on the person who lived through it.
Most people will encounter at least one traumatic event in their lifetime. In the U.S., 26% of children experience a traumatic event before the age of four, and two-thirds will face at least one traumatic event before turning 16.

Trauma left unaddressed does not resolve on its own. At Holina Rehab, understanding trauma is the starting point for treating it as part of addiction recovery — not as a separate, standalone issue — through our Dual Treatment programme.
Adults who report four or more adverse childhood experiences (ACEs) are four to twelve times more likely to develop alcohol or drug abuse problems than those with none (Felitti et al., CDC–Kaiser Permanente ACE Study; see CDC, About Adverse Childhood Experiences). A 2019 CDC analysis of more than 144,000 adults found 61% had experienced at least one ACE, and nearly 16% had experienced four or more (CDC Vital Signs, 2019). Among people in treatment for substance use disorders, research places the rate of co-occurring PTSD as high as 20–50% (Van den Brink, European Journal of Psychotraumatology, 2015). Holina’s Dual Treatment programme is built to address both together, not one after the other.
How Is Trauma Connected to Addiction?
Unresolved trauma changes how the brain and body manage stress — and substances often become the fastest available way to quiet that dysregulation. These are the mechanisms our clinical team sees most often linking trauma and addictive behaviour.
Self-Medication
Alcohol or drugs numb intrusive memories, panic, and hyperarousal, offering fast but temporary relief that can escalate into dependence.
Nervous System Dysregulation
Trauma keeps the body’s stress-response system activated long after the danger has passed, and substances are often used to force it back down.
Avoidance Coping
Substance use lets a person avoid places, people, and feelings connected to the trauma — the same avoidance pattern trauma itself produces.
Complex & Childhood Trauma
Prolonged or repeated trauma in childhood carries the strongest documented links to later substance use disorder (see the Clinical Fact above).
Shame & Secrecy
Both trauma and addiction thrive in silence, reinforcing each other and making either one harder to disclose or treat in isolation.
Re-Traumatization Risk
Poorly supported detox or unsupported early recovery can echo the powerlessness of the original trauma, increasing the risk of relapse into old coping patterns.
Disrupted Reward Circuitry
Chronic traumatic stress and substance use both alter the brain’s reward and threat systems, which is part of why the two conditions so often reinforce each other.
Numbing Emotional Pain
Where a traumatic memory hasn’t yet been processed in therapy, substances can become the default way to switch difficult feelings off.
Group & Vicarious Trauma
First responders, military personnel, and caregivers exposed to others’ trauma face elevated addiction risk from the same self-medicating patterns.
What Are the Signs of Unresolved Trauma?
Trauma manifests differently in each person, but certain emotional, behavioural, and physical signs are common — and when substance use appears alongside them, it is often functioning as an unhealthy coping strategy for the trauma underneath.
Signs Worth Taking Seriously
-
Emotional & Psychological Signs
Panic attacks, being constantly on edge or hyperaware, feeling anxious, frightened, resentful, or unsafe, losing interest in everyday activities, irritability, excessive worrying or crying, and symptoms of depression.
-
Behavioural Signs
Avoiding anything that reminds you of the event, withdrawing from loved ones, disturbed sleep patterns often with nightmares, and — significantly — turning to alcohol or drugs to manage these symptoms.
-
Physical Signs
Headaches, fatigue, digestive problems, excessive sweating, a rapid heartbeat, and being easily startled.
If substance use has become part of how you or someone you love copes with a past traumatic event, that is not a moral failing — it is a recognisable, treatable pattern. Our Dual Treatment programme is built to treat exactly this combination.
How Does Holina Rehab Treat Trauma as Part of Addiction Recovery?
Dual Treatment — Addiction and Trauma, Together
Trauma is addressed as a root cause of addiction, not as a standalone retreat. Where unresolved trauma is driving substance use, our trauma therapist integrates trauma-focused psychotherapy and EMDR within the residential programme, alongside the 12-Step model, CBT, and DBT.
All of this is delivered from day one under a single integrated plan — our Dual Treatment programme — so clients are never referred elsewhere for the trauma work their recovery depends on.
Evidence-Based Trauma Therapies
EMDR, somatic therapy, and trauma-informed approaches resolve the experiences that often drive addictive behaviour — without re-traumatising.
Our Trauma Therapist, Marc Rower, integrates 12-step recovery with trauma-focused psychotherapy to uncover the root causes of addictive behaviour, build internal resources, and support lasting relapse prevention.
Our Clinical Team
Treatment at Holina Rehab is led by qualified medical professionals and experienced addiction therapists. Every client is under active clinical supervision throughout their programme.

Trauma and Addiction: Frequently Asked Questions
Is trauma the same as addiction?
No. Trauma is the psychological and physiological injury caused by an overwhelming event; addiction is compulsive substance use despite harmful consequences. They are separate conditions, but for many people in recovery the two are directly linked — trauma often precedes and helps sustain addictive behaviour, so treating the addiction without also addressing the underlying trauma leaves the root cause active.
Why do people with unresolved trauma turn to drugs or alcohol?
Substances can temporarily numb the hyperarousal, intrusive memories, and emotional pain that trauma causes — a pattern often described as self-medication. Over time, this coping mechanism can develop into a substance use disorder, even though it started as an attempt to manage unresolved trauma.
How common is it for people in addiction treatment to have unresolved trauma?
Very common. Research on treatment-seeking patients with substance use disorders finds a substantial proportion also meet criteria for PTSD, and the CDC–Kaiser Permanente ACE Study found that adults with four or more adverse childhood experiences are four to twelve times more likely to develop alcohol or drug problems (Felitti et al., 1998; CDC, 2019 Vital Signs).
What is Dual Treatment and how does it address trauma?
Dual Treatment is Holina Rehab’s integrated model for treating addiction and any underlying behavioural health condition — including trauma — simultaneously, rather than treating one and referring the other elsewhere. Learn more about our Dual Treatment programme.
Can trauma be treated without stopping substance use first?
Trauma-focused work is only safe and effective once a person is medically stable, which is why Holina Rehab begins with a clinical assessment and, where needed, medically supervised detox before trauma therapies such as EMDR or somatic work begin — all within a single residential programme.
What if I’m not sure whether what I experienced counts as trauma?
Trauma is defined by its lasting impact, not by how severe an event might look from the outside. If a past experience is still affecting your sleep, relationships, emotions, or substance use today, it is worth a professional assessment — you don’t need certainty to reach out.
