Post-traumatic stress disorder and addiction: dual diagnosis

Reviewed by: Dr. Mahmoud El-Sawy Last updated: September 28, 2026 12 min read
The short answer

PTSD and addiction often occur together because people with PTSD turn to alcohol, sedatives, cannabis or opioids to numb memories, get to sleep and calm tension. This brings temporary relief, but it interferes with the processing of the memory and increases nightmares and anxiety once the effect wears off, creating a vicious cycle. The best approach is integrated treatment for both conditions together in a single plan.

  • A person is not required to "recover from addiction first" before trauma treatment can begin; the two can be treated in parallel.
  • Stopping sedatives and alcohol needs medical supervision because of the risk of severe withdrawal.
  • Treating the trauma reduces the drivers of relapse, and treating the addiction makes trauma treatment possible.

Why do people with trauma turn to substances?

What doctors call "self-medication" is usually an attempt to survive unbearable pain rather than a search for pleasure. The person is looking for:

Sleep without nightmares

They drink or take a sedative so they can sleep deeply and not wake up terrified.

Silencing the memories

Numbing intrusive images and sounds, even if only for a few hours.

Calming hyperarousal

Easing the constant tension and being on edge in the body.

Being able to socialize

Getting through social situations and crowded places.

Feeling something

Sometimes breaking through emotional numbness, especially with stimulants.

At first the substance seems like a "successful solution." Then the body needs larger amounts for the same effect, and the symptoms come back stronger when the effect wears off, so the person returns to the substance again.

Which substances are most closely linked to trauma?

Substances commonly used with PTSD
SubstanceWhy people use itHow it makes the problem worse
AlcoholTo sleep, forget the memories and ease tensionDisrupts sleep quality in the second half of the night, increases depression and impulsivity, and withdrawal can be dangerous
Benzodiazepines such as Xanax and RivotrilFast relief from anxiety, panic and insomniaRapid dependence; they may interfere with processing the memory, and stopping them suddenly can cause seizures
Hashish and bangoRelaxation and temporarily fewer nightmaresIncreases anxiety and symptoms in the long term, and can cause psychosis in some people
Opioids such as tramadol and heroinNumbing physical and emotional pain togetherSevere addiction and risk of overdose, especially when combined with sedatives or alcohol
PregabalinCalming anxiety and tensionMisuse is common, and the risk rises when combined with opioids and sedatives

How substances make PTSD worse

Some people with PTSD may turn to stimulants to fight numbness or exhaustion, or to stay alert, but these increase tension, suspiciousness and insomnia, and can lead to psychosis.

How do substances make trauma symptoms worse?

  • Blocking natural processing: numbing the memory stops the brain from digesting it, so it stays vivid and sharp.
  • Rebound symptoms: when the effect wears off, or during withdrawal, anxiety, insomnia and nightmares increase, and withdrawal symptoms may resemble the hyperarousal itself.
  • Worse sleep: alcohol and sedatives produce broken, unrefreshing sleep even though they make you drop off faster.
  • Depression and impulsivity: substances increase sadness and recklessness, and using them to manage symptoms is linked to a higher risk of suicidal thoughts.
  • New traumas: substance use increases exposure to accidents, violence and dangerous situations.

What signs should cause concern?

  • Drinks or takes a sedative every night "so they can sleep."
  • The amount has increased, or they now need it at more times during the day.
  • Becomes angry or tense when they cannot get the substance, or hides their use.
  • Takes sedative medication without a prescription or from more than one doctor.
  • Combines alcohol with sedatives or opioids.
  • Use increases around an anniversary or news that reminds them of the event.

What is integrated treatment for trauma and addiction?

In the past, some programs required patients to stop using substances completely before any discussion of trauma. Today, guidelines, including NICE, advise that a patient should not be denied trauma treatment simply because of an alcohol or drug problem, and that both conditions should be treated in a coordinated way. Integrated treatment includes:

  1. Safe withdrawal from substances under medical supervision, especially alcohol and sedatives because of the risk of seizures, along with regulating sleep.
  2. Stabilization and skills: learning healthy alternatives for coping with memories and cravings, such as "Seeking Safety" programs, which combine trauma and addiction topics.
  3. Trauma-focused therapy: trauma-focused cognitive behavioral therapy or EMDR once the patient is stable enough, and some programs combine it with addiction treatment from the start.
  4. Medication: treatment for accompanying depression or anxiety, and medications that support addiction treatment depending on the substance, without resorting to sedatives that cause dependence.
  5. Relapse prevention: a plan that identifies both trauma triggers and substance use triggers.

Why does treating only one fail?

A person treated for addiction alone who then returns to life with the memories still vivid finds that the reason that drove them to use is still there, so the risk of relapse rises. A person who tries to treat the trauma while deep in substance use struggles to attend sessions and benefit from them. That is why coordination between the two teams, or having both in one place, is the shortest path to recovery.

Why do trauma symptoms get worse when substance use stops?

When the substance that was numbing the memories stops, nightmares, anxiety and hyperarousal return, and may intensify in the first weeks. This is expected and does not mean that stopping was a mistake, but it is one more reason for withdrawal to take place under a team that understands trauma and prepares the patient with calming skills and a sleep plan before and after stopping.

How can the family help?

  • Understand that substance use may be a desperate attempt to ease the pain of trauma, without that meaning you accept it.
  • Speak calmly about the worry you feel, and avoid accusations and threats in moments of tension.
  • Do not keep alcohol or sedatives at home, and do not give your own medication to anyone.
  • Encourage a specialist assessment for dual diagnosis, and offer to go along.
  • Seek support for yourself too, through family sessions or support groups.

Suicidal thoughts or danger to self? Get help now

  • Talking about wanting to die, or that life is no longer worth living, or that others would be better off without them
  • Severe despair and a feeling that the pain will never end, or overwhelming guilt and shame tied to the event
  • Saying goodbye to family and friends, or suddenly giving away treasured belongings
  • Severe detachment from reality, or reliving the memory as if it is happening now, with agitation that does not settle
  • A sudden increase in drinking alcohol or using sedatives or drugs, or dangerous impulsiveness and recklessness

Stay with the person and do not leave them alone, listen calmly without judgment or argument, and ask them directly about their thoughts; asking does not plant the idea. Call ambulance (123) or go to the nearest emergency department, or call the mental health support line 16328, and keep medication and objects that could harm them out of reach until help arrives.

Ask on WhatsApp
Does drinking to forget the trauma mean I am addicted?

Not necessarily, but it is an important warning sign. If drinking or a sedative has become your main way of sleeping or coping with memories, or the amount has increased, this is a good time for a specialist assessment, before it turns into addiction.

Can trauma be treated while I am still using?

Assessment, stabilization and skills can begin right away, and guidelines advise against excluding a patient from trauma treatment because of substance use, but the plan coordinates reducing substances and withdrawing from them safely with trauma treatment.

Why have my nightmares increased since I stopped using cannabis or alcohol?

Because these substances were temporarily suppressing dreams and memories, and when you stop, dreams rebound and become more intense for a while. This is usually temporary, and treatment helps you get through it without going back to the substance.

Is Xanax an appropriate treatment for PTSD?

Benzodiazepines such as Xanax are not recommended for treating or preventing the disorder, because they do not treat it, may hinder recovery and cause dependence, and stopping them requires medical supervision.

Does childhood trauma cause addiction in adulthood?

Exposure to violence, abuse or neglect in childhood clearly raises the risk of addiction later in life, but it does not make it inevitable, and early support and treatment reduce this risk.

What is the Seeking Safety program?

A structured treatment program used with people who have both trauma and addiction. It focuses on building safety and practical skills, without going into the details of the trauma in its early stages.

Is relapse after addiction treatment linked to trauma?

Often it is, if the trauma has not been treated; memories, nightmares and tension remain strong drivers to go back to using, which is why treating both together reduces the risk of relapse.
