The link between PTSD (Post-Traumatic Stress Disorder) and substance use is one of the most robust findings in addiction research. Studies consistently show that people with PTSD are 24 times more likely to develop a substance use disorder and people presenting for addiction treatment have PTSD at rates far above the general population.
Understanding this connection explains why treating the addiction alone is often insufficient for lasting recovery.
What Is PTSD?
PTSD is a mental health condition that develops after exposure to a traumatic event or series of events. It is characterised by:
- Intrusive symptoms: flashbacks, nightmares, intrusive memories that recreate the sensory and emotional experience of the trauma
- Avoidance: deliberately avoiding thoughts, feelings, or external reminders of the trauma
- Negative alterations in cognition and mood: persistent negative beliefs (“I am damaged”), emotional numbing, estrangement from others, persistent guilt or shame
- Hyperarousal: hypervigilance, exaggerated startle response, irritability, sleep disturbance, difficulty concentrating
PTSD affects approximately 10-20% of people exposed to trauma. Risk factors include severity of the trauma, lack of social support, prior trauma history, and individual neurobiological vulnerability.
The PTSD-Addiction Cycle
How PTSD Drives Substance Use
Substance use often begins as an attempt to manage PTSD symptoms:
- Alcohol reduces hyperarousal and dampens the nervous system’s reactivity. Many PTSD sufferers drink to sleep, or to prevent nightmares.
- Opioids produce a sense of calm and emotional distance from traumatic memories
- Cannabis may temporarily reduce anxiety and hypervigilance
- Benzodiazepines suppress the panic and anxiety responses associated with trauma triggers
This self-medication produces short-term relief. But it comes at a significant cost:
- Substances prevent the natural emotional processing that helps trauma resolve
- Substance use worsens PTSD symptoms over time, particularly depression and emotional numbing
- The substance becomes its own trauma adding shame, relationship damage, and health consequences to the existing burden
How Addiction Worsens PTSD
The relationship is bidirectional: substance use also worsens PTSD:
- Alcohol worsens sleep quality and increases the intensity of nightmares
- Stimulants increase hyperarousal
- Withdrawal produces anxiety and panic that mimics PTSD symptoms
- The chaos and consequences of addiction add new traumatic experiences
Common Trauma Types We See at Anker Huis
The combination of trauma and addiction presents across many different trauma backgrounds:
| Trauma Type | Common Substance(s) |
|---|---|
| Childhood physical/sexual abuse | Alcohol, opioids |
| Domestic violence | Alcohol |
| Combat trauma / security sector | Alcohol, cannabis |
| Accident/injury | Opioids, benzodiazepines |
| Sexual assault | Alcohol, benzodiazepines |
| Bereavement | Alcohol |
| Occupational trauma (first responders) | Alcohol, stimulants |
Why Treating Only the Addiction Is Insufficient
Consider someone with alcohol use disorder and underlying PTSD who completes a detox and standard addiction rehabilitation programme. They leave:
- Sober
- Still experiencing intrusive memories and nightmares
- Still hypervigilant and unable to relax
- Still avoiding situations that trigger memories
- Without the substance that was managing these symptoms
The relapse risk is predictably high not because the person has failed, but because the driver of the alcohol use has not been addressed.
Integrated treatment of PTSD and addiction treating both simultaneously consistently produces better outcomes.
Anker Huis: Integrated PTSD and Addiction Treatment
At Anker Huis, PTSD is assessed as part of every client’s comprehensive assessment. For those with PTSD and addiction, our integrated treatment plan includes:
Trauma-Informed Environment
Our environment is designed for safety: consistent staff, predictable structure, clear boundaries, and a culture of respect. For trauma survivors, safety is the prerequisite for healing.
Stabilisation First
Trauma processing work begins only after physical stabilisation from withdrawal and establishment of adequate coping resources. Opening trauma before someone is stable can be retraumatising.
Trauma-Specific Therapies
Our therapists are trained in:
- EMDR (Eye Movement Desensitisation and Reprocessing)
- Trauma-Focused CBT
- Somatic approaches for body-held trauma
Parallel Addiction Treatment
Addiction treatment proceeds alongside trauma work, individual therapy, group therapy, relapse prevention planning, and aftercare.
Psychiatric Support
Many clients with PTSD and addiction benefit from pharmacological support for PTSD symptoms (SSRIs, prazosin for nightmares), for sleep, and for any co-occurring depression.
FAQ: PTSD and Addiction
Can PTSD be treated while also treating addiction? Yes, and evidence supports doing both simultaneously rather than sequentially. Integrated treatment produces better outcomes.
Is it common to have PTSD and addiction at the same time? Very common. Studies show 25-50% of people seeking addiction treatment meet criteria for PTSD.
Does Anker Huis provide EMDR therapy? Yes. EMDR is available as part of our individual therapy offering for clients where trauma is a clinical focus.
