If you or someone you love is struggling with both trauma and substance use, you are not alone. The connection between PTSD and addiction is well established, and many people face both challenges at the same time. Understanding how these two conditions interact is an important first step toward finding the right kind of help.

Post-traumatic stress disorder, or PTSD, can develop after a person experiences or witnesses a deeply distressing event. Substance use disorders often develop alongside it — sometimes as a way to manage overwhelming emotions, intrusive memories, or physical tension. When both conditions are present together, they reinforce each other in ways that can make recovery feel out of reach.

The good news is that effective, integrated treatment exists. At Milestone Recovery in Phoenix, Arizona, we work with people facing exactly this kind of complex challenge every day. Below, we explain what the research tells us, what treatment can look like, and how to take a meaningful step forward.

Understanding the Link Between PTSD and Substance Use

PTSD and substance use disorders frequently occur together. Studies consistently show that people with PTSD are significantly more likely to develop a substance use disorder than those without it. Similarly, people in addiction recovery often carry unresolved trauma that was never properly addressed.

This overlap is not a coincidence. It reflects how the brain and body respond to overwhelming stress. When a person experiences trauma, the nervous system can become stuck in a state of high alert. Substances like alcohol, opioids, or benzodiazepines may temporarily quiet that alarm — which is why many people reach for them in the first place.

Why People With PTSD Turn to Substances

There are several common reasons why someone with PTSD might use substances:

• To quiet intrusive thoughts or flashbacks that feel impossible to control
• To manage hypervigilance, or the constant feeling of being on edge
• To get to sleep when nightmares and anxiety make rest difficult
• To feel emotionally numb when feelings become too intense to bear
• To reconnect socially when trauma has led to isolation and withdrawal

While substances may bring short-term relief, they often make PTSD symptoms worse over time. Alcohol, for example, disrupts sleep quality and can amplify anxiety. This cycle — where substances temporarily ease symptoms but ultimately deepen them — is one reason integrated treatment is so important.

What Is a Co-Occurring Disorder?

When a person experiences both a mental health condition like PTSD and a substance use disorder at the same time, this is called a co-occurring disorder. It is also sometimes referred to as a dual diagnosis. Treating only one condition while ignoring the other often leads to relapse or worsening symptoms. Because of this, the most effective approach addresses both issues together, using a coordinated and personalized plan.

How PTSD Affects the Brain and Body

To understand why PTSD and addiction so often go hand in hand, it helps to understand what trauma does to the brain. Trauma changes the way the brain processes fear, memory, and emotion. Areas like the amygdala — the brain’s alarm center — can become overactive, while the prefrontal cortex, which helps regulate emotion and decision-making, becomes less effective.

These neurological changes can make a person feel unsafe even in calm environments. They can also make it harder to regulate emotions, make decisions, or resist impulsive behaviors. This is not a character flaw. It is a measurable, biological response to overwhelming stress.

Common PTSD Symptoms to Recognize

PTSD symptoms vary from person to person, but they often include:

• Intrusive memories or flashbacks of the traumatic event
• Nightmares that interrupt sleep and leave a person exhausted
• Emotional numbness or feeling detached from others
• Hypervigilance, or a constant sense of danger or alertness
• Avoidance of people, places, or situations that trigger memories
• Irritability, anger, or sudden emotional outbursts
• Difficulty concentrating or feeling mentally foggy

If these symptoms sound familiar, please know that they are recognized, treatable, and not a sign of weakness. Many people carry these experiences quietly for years before seeking support. It is never too late to reach out.

Evidence-Based Treatment for PTSD and Addiction

Integrated treatment — meaning care that addresses both PTSD and substance use at the same time — is widely recognized as the most effective approach. At Milestone Recovery, we offer a range of evidence-based therapies designed to support healing on every level.

Cognitive Behavioral Therapy (CBT)

Cognitive behavioral therapy is one of the most well-researched treatments for both PTSD and addiction. CBT helps people identify thought patterns that drive distress and compulsive behavior. Through structured sessions, clients learn to challenge unhelpful beliefs, develop healthier coping strategies, and build greater emotional resilience. It is practical, goal-oriented, and grounded in decades of clinical research.

EMDR Therapy

Eye Movement Desensitization and Reprocessing, or EMDR, is a specialized therapy designed specifically for trauma. It helps the brain reprocess painful memories in a way that reduces their emotional intensity. Many clients who have not responded to talk therapy alone find meaningful relief through EMDR. At Milestone Recovery, our trained clinicians use EMDR as part of a broader, personalized treatment plan.

Dialectical Behavior Therapy (DBT)

DBT is particularly helpful for people who experience intense emotional swings or difficulty regulating their feelings. It combines elements of cognitive therapy with mindfulness and acceptance strategies. DBT gives clients practical tools for managing distressing moments without turning to substances. These skills are directly applicable to daily life.

Medication-Assisted Treatment (MAT)

For many people, medication plays an important supporting role in recovery from substance use disorders. Medication-assisted treatment uses FDA-approved medications to reduce cravings, ease withdrawal symptoms, and stabilize mood. At Milestone Recovery, MAT is offered alongside therapy — never as a standalone solution — as part of a comprehensive, individualized care plan.

Ketamine-Assisted Therapy

Milestone Recovery also offers ketamine-assisted therapy for clients experiencing treatment-resistant depression, trauma, and PTSD. Under careful medical supervision, ketamine has shown promising results in reducing symptoms when other approaches have not been sufficient. This option is evaluated on an individual basis and always combined with ongoing therapeutic support.

What Treatment at Milestone Recovery Looks Like

Milestone Recovery offers two structured program levels to meet clients where they are in their recovery journey.

Partial Hospitalization Program (PHP)

Our Partial Hospitalization Program provides a highly structured therapeutic environment with daily group and individual therapy sessions, psychiatric assessments, and medication management. PHP is well suited for clients who need intensive support but do not require inpatient hospitalization. It offers the depth of care needed to address both trauma and substance use in a focused, consistent way.

Intensive Outpatient Program (IOP)

Our Intensive Outpatient Program offers a more flexible schedule for clients who need meaningful support while still managing work, school, or family responsibilities. IOP delivers structured therapy and accountability without requiring a full-time commitment. Many clients step down from PHP into IOP as they progress in their recovery.

Whole-Person Wellness

Recovery from PTSD and addiction involves more than clinical therapy. At Milestone Recovery, we also incorporate nutritional education, fitness, outdoor activities, and mindfulness and grounding techniques into our programs. Our certified therapy dog, Luna, offers a gentle, calming presence that many clients find deeply supportive. We believe that healing the whole person — mind, body, and spirit — leads to more lasting change.
