Treatment for co-occurring PTSD and addiction is trauma-informed integrated care that addresses post-traumatic stress and substance use disorder together, not sequentially. At Radix Recovery in Cedar Rapids, Iowa, one clinical team delivers, prolonged exposure, cognitive processing therapy, and somatic work alongside addiction treatment, with daily psychiatric oversight and non-addictive medication management. Roughly half of adults in addiction treatment meet criteria for PTSD, which makes trauma-competent dual diagnosis treatment essential for durable recovery.

Adults living with PTSD often spend years managing the intrusive memories, hypervigilance, sleep disruption, and physical activation with whatever quiets the alarm system. For many, that becomes a substance. Alcohol numbs the hyperarousal. Opioids dull the emotional pain. Benzodiazepines flatten the panic. The relief is real, which is exactly why the pattern becomes a substance use disorder over time, and exactly why the trauma symptoms eventually return worse than before.
Treating the addiction without addressing the trauma rarely produces lasting recovery, which is why both conditions are treated together from day one.
The link between PTSD and substance use disorder is one of the strongest in the comorbidity literature. Adults with PTSD are two to four times more likely to develop a substance use disorder compared to the general population,[1] and roughly half of adults in addiction treatment also meet criteria for PTSD.[2] The mechanism is the trauma response itself.
PTSD keeps the autonomic nervous system locked in self-protection. Hyperarousal makes rest impossible. Intrusive memories appear without warning. The startle response stays elevated. The physical exhaustion of carrying this load every day creates background suffering that substances temporarily quiet. Alcohol slows the nervous system. Opioids dull emotional pain. Cannabis flattens the activation.
The substance use, in turn, deepens the PTSD over time. Sleep disrupted by alcohol prevents the memory processing the brain needs to integrate trauma. Withdrawal intensifies hyperarousal. Substance use frequently exposes individuals to additional trauma. The two conditions reinforce each other until both are treated together.

Not all trauma presents the same way. The clinical distinction between PTSD and Complex PTSD matters because the treatment approach differs in meaningful ways.
Note: our intake assessment differentiates the two and adjusts the treatment plan accordingly, including the pacing of trauma processing work.
Develops after a discrete traumatic event or set of events: combat exposure, sexual assault, serious accident, natural disaster, sudden loss. The four DSM-5 symptom clusters[6] (intrusion, avoidance, negative mood and cognition, hyperarousal) are the defining features. Standard trauma-focused therapies (PE, CPT) have strong evidence in classic PTSD.[3]
The distinction is made through clinical history and assessment at intake. cPTSD typically requires extended stabilization before active trauma processing begins, while classic PTSD can often move into trauma-trained or prolonged exposure sooner once the resident is stable. The treatment plan is built around which presentation is present.
Each substance quiets the trauma response in a different way, and each one carries a different cost. Select a substance to see how the short-term relief turns into the long-term cycle.
Select a node from the wheel to see how it connects.
Alcohol is the most common substance used to manage PTSD symptoms because it acts quickly on the GABA system to reduce hyperarousal and force sleep. Daily drinking is particularly common in veterans with combat PTSD and in adults with cPTSD.
The cost is severe alcohol disrupts the REM sleep the brain needs to process traumatic memories, which delays recovery even after the drinking stops.
Treating PTSD in alcohol recovery is central to preventing relapse.
Opioids are heavily used in PTSD because they dull both physical and emotional pain. Adults with chronic pain plus PTSD are at particular risk.
Opioid use disorder is a well-documented complication of long-term post-trauma pain management.
The fatal overdose risk in PTSD plus opioid use is elevated.
Daily cannabis use is increasingly common in PTSD, often pursued as self-medication for sleep and intrusive memories.
The evidence is mixed short-term low-dose cannabis may reduce some symptoms, but heavy daily use is associated with worse long-term PTSD outcomes.
Heavy use complicates recovery and the trauma processing work.
Frequently prescribed for PTSD-related anxiety and panic, benzodiazepines produce rapid tolerance and dependence.
Current VA/DoD guidelines do not recommend benzodiazepines for long-term PTSD management.
We do not use them for ongoing PTSD treatment in our recovery population.
Trauma-informed care is a framework, not a buzzword. SAMHSA defines it as care that realizes the widespread impact of trauma, recognizes the signs in residents and staff, responds by integrating trauma knowledge into practice, and resists actively re-traumatizing those it serves.[1] We operationalize all four pillars, and they shape lighting, seating, exit-aware room design, group facilitation, and ongoing staff training across every role.
We realize the widespread impact of trauma and understand potential paths to recovery. Trauma is treated as a likely part of the clinical picture, not an exception.
We recognize the signs and symptoms of trauma in residents, families, and staff, so the response is informed rather than reactive.
We respond by integrating trauma knowledge into policies, procedures, and practice, from how questions are asked at intake to how groups are facilitated and how physical space is designed.
We actively resist re-traumatizing the people we serve. Staff training is ongoing, not a one-time onboarding, and is part of standard credentialing for every role that interacts with residents.
Prolonged Exposure (PE) and Cognitive Processing Therapy (CPT) are two structured, evidence-based therapies developed for trauma processing. They are among the most studied trauma treatments and are both recommended in the APA Clinical Practice Guideline for PTSD and the VA/DoD Clinical Practice Guideline. PE works by helping you gradually and safely approach the memories and situations you have been avoiding, so the nervous system learns they are no longer a present-day threat — while CPT targets the "stuck point" beliefs trauma leaves behind, about safety, trust, and self-blame, and helps replace them with more balanced ones.
We take a careful trauma and substance-use history and map which memories will be targeted. Nothing is rushed, and you are never required to share more than you are ready to.
Before any trauma is touched, we build distress-tolerance and grounding skills through DBT work. This is the stabilization that makes the later phases safe in early recovery.
A specific target memory is identified along with the negative belief attached to it and the more adaptive belief we are working toward.
The memory is held in mind alongside bilateral stimulation, guided eye movements or alternating taps, until the distress it carries begins to drop.
The adaptive belief is strengthened and linked to the target memory, so recall no longer pulls the nervous system back into self-protection.
Because trauma lives in the body, we check for residual physical tension tied to the memory and process anything that remains.
Every session ends with the resident grounded and stable, never left activated. Self-regulation skills bridge the time between sessions.
At the next session we check what held and what still needs work, then plan the next target. EMDR can continue at lower frequency into outpatient care.
In dual diagnosis treatment, trauma processing is integrated into the active treatment phase, not deferred to aftercare. We begin with the resourcing and stabilization phases, build distress tolerance through DBT skills work, and only move into active PE or CPT reprocessing when you are stable enough to do so safely. This work is delivered by trained clinicians on staff, never outsourced or referred away.
Group therapy is part of standard addiction treatment, and for many residents it is one of the most healing components. But for adults with PTSD, poorly facilitated groups can re-traumatize. Hearing detailed accounts of others trauma, being asked to share more than is safe, or sitting in an environment that activates the nervous system can intensify PTSD rather than treat it.
Clear sight lines, consistent seating, and an unblocked exit. The physical room is designed to lower activation, not raise it.
This is what trauma-informed care looks like in practice, day after day.
Radix Recovery treats veterans across our dual diagnosis program, with clinicians familiar with VA-aligned trauma protocols and the specific dynamics that combat exposure, military sexual trauma, and reintegration produce.
We accept TriWest Healthcare Alliance for veteran coverage, alongside our standard insurance partnerships, so cost is not a barrier to trauma-competent care.
Veteran-specific programming, including dedicated programming for veterans-only cohorts and military family support, is covered in depth on our veteran rehab page. This PTSD page is the broader clinical treatment overview; the veteran rehab page is the deep-dive on military-specific care.
Dual diagnosis means finding and treating the conditions that were driving, hiding, or made worse by substance use.
Our team completes a PTSD evaluation, a substance use assessment, medical and trauma history, and a screen for complex PTSD presentation. Both conditions are documented in one integrated chart. Trauma history is taken with clinical care; residents are never required to disclose more than they are ready to.
Transition into PHP, IOP, and continuing care under the same team. Trauma processing can continue at lower frequency into outpatient care. Relapse prevention plans account for trauma anniversaries, triggers, and the situations that activate the nervous system. Medication continues under Radix psychiatry.
SSRIs and SNRIs
Prazosin
Originally a blood pressure medication, prazosin reduces trauma-related nightmares and improves sleep quality in PTSD. Particularly useful in veterans with combat-related nightmares.[3] Not a controlled substance.
Medications we are cautious with
Benzodiazepines are not recommended for ongoing PTSD management per VA/DoD guidelines.[5] Antipsychotics are used selectively and only when clinically indicated. The first-line approach is always the trauma-focused therapies, with medication as a supportive layer.
If trauma has been driving the substance use, treating only the addiction does not address what is underneath. Confidential admissions available 24/7.
