Trauma & Addiction: Why PTSD & Substance Use Often Go Hand in Hand

Understanding the Connection Between Trauma and Addiction

Is There a Link Between Trauma and Addiction?

Yes, there is a well-documented link between experiencing a traumatic event and having substance use disorder. 

Many people who live with alcohol use disorder (AUD) or substance use disorder (SUD) also live with post-traumatic stress disorder (PTSD). Trauma fundamentally changes how a person’s brain processes stress, making them more prone to substance abuse as they seek out ways to cope with overwhelming emotions.

Luckily, with the right compassionate and holistic support, managing both conditions is possible. The goal is to create a space for healing rather than a cycle of distress.

How Do Traumatic Experiences Affect Mental Health?

Trauma overloads the nervous system, making it hard for the person to manage even some of the most common stressors, often leading them to self-medicate. 

People who have experienced trauma are usually turning to substances for relief, like finding an “off” switch for a horror film you didn’t want to watch.

Traumatic experiences can also trigger long-term mental health conditions like PTSD, severe anxiety, and clinical depression. Each of these is a mental illness that can make daily life feel painful or even dangerous. 

Why Do People Self-Medicate After Experiencing Trauma?

When someone is dealing with intrusive memories and stuck in a constant state of panic, they’ll turn to anything that can help them feel normal for a while, including alcohol and drugs. 

Self-medicating might look like self-destruction, but more often than not, these are people just trying to survive their day. 

The problem is that substance abuse only numbs the pain temporarily. Continued alcohol or drug use ultimately worsens the underlying mental health condition. This creates a feedback loop, making an already addictive substance feel vital to survival.

Understanding PTSD After Trauma

What Is Post-Traumatic Stress Disorder (PTSD)?

PTSD is a mental health condition that can develop after experiencing or witnessing a distressing event. 

Not everyone who goes through trauma will develop PTSD, and trauma itself is relatively common for people to experience at some point in their lives. However, those who end up with nervous systems constantly on high alert could have PTSD, and their body will remain trapped in the past years after the real danger is gone.

What Are the Common Symptoms of PTSD?

PTSD looks different for everyone, but common signs include:

• Flashbacks or nightmares: This is more than just remembering the event. Often, the person physically feels like they’re experiencing their traumatic experiences all over again in the present moment.
• Hypervigilance: Feeling constantly on edge, easily startled, or as if you need to be on guard for hidden dangers.
• Avoidance: Going out of your way to avoid anything that might trigger PTSD symptoms or bring up painful memories. People with PTSD will often do this to their detriment. They even avoid tasks or places that could alleviate their PTSD symptoms for fear of being triggered.
• Mood swings: Experiencing sudden shifts in emotions. This can range from irritability to sadness, and usually without a clear cause. 
• Feeling emotionally numb: A defense mechanism where the brain structure learns to shut down emotional responses entirely. This is theoretically useful for PTSD, and it is meant to be a defense mechanism, but it makes it difficult to feel joy or connect with others.

Can PTSD Develop Years After a Traumatic Event?

Yes. Delayed-onset PTSD happens when symptoms lie dormant for months or years after traumatic events. 

This often occurs when a new stressor triggers the nervous system. Unfortunately, this can also happen when the brain finally feels “safe” enough to process. As the brain unpacks the memories, the body may experience trauma all over again, leading to PTSD symptoms.

How Trauma & PTSD Change the Brain and Increase Addiction Risk

What Are the Top 3 Forms of Trauma That Lead to Addiction?

Three notable forms of trauma are commonly associated with higher rates of addiction:

• Childhood trauma: Abuse or neglect are clear catalysts for PTSD. But even living in an unstable environment can lead to adverse childhood experiences (ACEs) that change the brain.
• Sexual abuse: Assault or exploitation at any stage of life.
• Chronic interpersonal trauma: Domestic violence or emotional abuse over a sustained period.

However, any type of trauma can increase the risk of addiction. Many other experiences, like surviving a severe car accident, surviving natural disasters, or time in a combat environment, are also common risk factors that cause trauma and addiction.

How Do Adverse Childhood Experiences (ACEs) Affect Brain Development?

If a person experiences high levels of toxic stress during childhood or adolescence, their brain can literally change how it grows. 

Adverse childhood experiences (ACEs) happen during the most crucial times for healthy brain development. Impulse control, emotional processing, and stress regulation can all be heavily impacted by these events. This can cause the adult to have a lifelong vulnerability to addiction.

Why Does Trauma Change the Brain’s Stress Response?

Past trauma can lock the brain into a chronic “fight-or-flight” state. 

PTSD already affects parts of the brain that deal with memory, emotion, and fear, especially the amygdala and hippocampus. Alcohol and drugs affect those same areas, making the brain even more sensitive to stress over time.

Over time, substance abuse can:

• Increase depression and irritability
• Make it harder to think clearly
• Cause memory loss and blackouts
• Lead to risky behavior or self-harm
• Lead to more traumatic incidents
• Worsen symptoms for co-occurring disorders

Substances may seem like an escape, but they add fuel to the fire of trauma. Addiction can cause a person to be in situations that cause more trauma, such as legal harm or abusive relationships. It can also deeply disrupt a person’s sense of self-worth and inner peace.

The Cycle of Trauma, PTSD, and Substance Use

What Is the Cycle of Trauma and Addiction?

The cycle of trauma and addiction is a self-reinforcing loop where the impact of trauma drives a person to use substances for relief, which in turn alters brain chemistry, worsens distress, and leads to more traumatic events.

The cycle works as follows:

• The Trigger: PTSD symptoms (like fear, stress, or insomnia) spike. The person turns to substances to self-medicate.
• The Relief: The substance does help, but only with a fleeting sense of calm or numbness that will inevitably worsen symptoms.
• The Rebound: The drink or drug wears off, and the brain’s chemistry rebounds. 
• The Intensification: The PTSD symptoms are even more pronounced.
• The Repetition: The person drinks again, since it technically worked in managing their distress. Unfortunately, this starts the cycle all over again.

How Do PTSD Symptoms Contribute to Substance Use?

Living with flashbacks and hypervigilance is exhausting, making a person feel like they’re trapped in their own body, trying to outrun thoughts that won’t stop coming; substances can offer immediate relief for these feelings.

Why Can Addiction Make PTSD Worse?

Chronic substance abuse or use can cause more intense mood swings and anxiety during withdrawal and prevent healing from occurring. 

Drug and alcohol use might buy a person with PTSD some temporary quiet, but it comes at the high cost of stripping away natural coping mechanisms. This causes the person to reach for more to escape the pain of those emotions. 

Substance use disorder also physically prevents the brain from processing traumatic memories. This practically guarantees that the substance use will continue to be a problem until the PTSD is addressed, and vice versa.

Trauma Responses and Their Role in Addiction Recovery

What Are the 7 Trauma Responses?

Most people are familiar with the “fight or flight” trauma response; however, some trauma experts point to there being seven ways the nervous system can respond to trauma or a traumatic experience:

• Fight: Get aggressive or defensive as a protective mechanism
• Flight: Flee or avoid the situation
• Freeze: Feeling stuck or paralyzed
• Fawn: People-pleasing to de-escalate and stay safe
• Flop: Physical collapse or complete submission
• Friend: Allying yourself with the source of danger
• Attachment (Cry for Help): Looking for help or comfort from others

What Is the Difference Between Healthy and Unhealthy Coping Mechanisms?

Healthy coping skills, like mindfulness, exercise, and talking through your feelings with a professional therapist, give your emotions space and help regulate your nervous system.

Unhealthy coping skills technically work, but only mask the pain and usually leave much larger problems in their wake. This includes avoiding problems or emotions, and substance use is a popular way to accomplish that.

Healthy coping mechanisms often don’t offer instant relief. It’s partially what makes them less appealing, especially to those with mental health problems or a history of drug abuse. But with time and patience, they can help you regulate your nervous system — permanently.

How Can Unresolved Trauma Affect Long-Term Well-Being?

Trauma quietly runs in the background of everyday life, worsening physical and mental health through chronic stress, damaging relationships, and acting as one of the biggest triggers for relapse.

Trauma-Informed Care for Co-Occurring PTSD and Addiction

What Are the 4 R’s of Trauma?

Trauma-informed care is guided by the Substance Abuse and Mental Health Services Administration’s (SAMHSA) “Four Rs”:

• Realize: Understanding just how impactful trauma is
• Recognize: Noticing signs and symptoms of trauma in clients
• Respond: Using this knowledge in all therapies and practices
• Resist Re-traumatization: Ensuring the treatment environment is safe

Why Is Trauma-Informed Care Important in Addiction Treatment?

Trauma-informed care helps addiction and mental health professionals understand the symptoms of trauma, minimizing the risks of re-traumatizing clients.

Once the substance is gone, repressed memories and feelings rush to the surface. Trauma-informed care focuses on teaching a person how to feel safe in their own body again, even when experiencing triggers or anxiety around their traumatic experiences.

What Evidence-Based Therapies Help Treat Trauma and Addiction Together?

Dual-diagnosis treatment programs for comorbid PTSD and substance use disorder use effective treatments such as cognitive-behavioral therapy (CBT) and dialectical behavior therapy (DBT).

In addition to CBT and DBT, trauma-focused therapy and motivational interviewing help clients heal old wounds and learn how to move forward from their trauma. Using a trauma-informed approach with these therapies also helps promote emotional regulation and healthy coping mechanisms.

Choosing the Right Trauma and Addiction Treatment Program

How to Choose a Trauma and Addiction Treatment Facility?

When choosing a treatment facility, it is imperative to ensure they offer dual-diagnosis expertise. 

This is crucial for managing substance use disorder and PTSD within the same person. Treatment centers should also ideally offer trauma-informed care: a specific type of care that respects the person’s relationship with their traumatic experiences every step of the way.

What Should You Expect From a Trauma-Informed Treatment Program?

You should expect clinical assessments, an individualized care plan, integrated psychiatric and behavioral health services, and holistic support. 

The amount of each you experience will depend on your providers and how they design your treatment plan. But the goal is always the same: your program is there to make you feel physically and emotionally secure.
