Post-traumatic stress disorder (PTSD) is a mental health condition that can develop after someone experiences or witnesses a shocking, scary, or dangerous event, such as violence, serious accidents, or natural disasters.(Source) While it is normal to feel afraid or distressed during and after a traumatic event, PTSD involves ongoing symptoms that last for more than one month and significantly interfere with daily life.(Source)

PTSD can affect anyone, at any age. Trauma that may lead to PTSD includes:

• Military combat and deployment
• Serious accidents or injuries (such as car crashes or workplace accidents)
• Natural disasters (such as tornadoes, floods, or hurricanes)
• Acts of terrorism or community violence
• Sexual assault, physical assault, or domestic violence
• Childhood abuse or neglect
• Sudden or unexpected death of a loved one
• Medical trauma, such as life-threatening illness or intensive care stays(Source)

In the United States, an estimated 5–6% of adults will experience PTSD at some point in their lives, and millions are affected in any given year.(Source) Women are diagnosed with PTSD at higher rates than men, although men are more likely to experience certain types of trauma such as combat or physical assault.(Source)

PTSD is not a sign of weakness or a character flaw. It is a treatable medical condition involving changes in how the brain and body respond to stress and threat.(Source)

PTSD affects how the brain processes memories, emotions, and perceived threats. For many people, the brain has difficulty distinguishing between past trauma and present-day experiences, causing everyday situations to feel unsafe or overwhelming.(Source)

Symptoms of PTSD usually begin within three months of a traumatic event, but in some cases they may not appear until months or even years later.(Source) Mental health professionals group PTSD symptoms into four main categories:

1. Intrusive Memories

• Recurrent, involuntary, and distressing memories of the event
• Nightmares or night terrors related to the trauma
• Vivid and intense flashbacks that feel like reliving the event
• Strong emotional distress when reminded of the trauma
• Physical reactions to reminders, such as rapid heartbeat, sweating, or panic(Source)

2. Avoidance

• Avoiding places, people, conversations, or activities that remind you of the trauma
• Trying not to think or talk about what happened
• Numbing out emotionally or feeling detached from others
• Putting off or refusing medical or mental health care because it feels too overwhelming(Source)

3. Negative Changes in Thoughts and Mood

• Persistent negative beliefs about yourself, others, or the world (for example, “I’m broken,” “No one can be trusted,” or “The world is completely dangerous”)
• Ongoing feelings of fear, horror, anger, guilt, or shame
• Difficulty experiencing positive emotions or feeling close to others
• Loss of interest in activities you once enjoyed
• Memory problems related to the traumatic event
• Feeling detached, isolated, or estranged from friends and family(Source)

4. Changes in Arousal and Reactivity

• Difficulty falling or staying asleep (insomnia)
• Feeling jumpy or easily startled
• Irritability, anger outbursts, or aggression
• Trouble concentrating or staying focused
• Hypervigilance (always being “on guard”)
• Self-destructive or risky behaviors, such as binge drinking, drug use, reckless driving, or self-harm(Source)

Without treatment, PTSD symptoms often do not simply fade away. In many people, symptoms can persist for years and may worsen over time, especially when combined with substance use or additional stress.(Source) Early, comprehensive treatment offers the best chance for long-term recovery.

PTSD and substance use disorders frequently occur together. Many people use alcohol or drugs to try to manage overwhelming symptoms such as anxiety, panic attacks, insomnia, or intrusive memories. This is known as “self-medicating.”(Source)

Research suggests that people with PTSD are significantly more likely to develop a substance use disorder than those without PTSD.(Source) Among individuals who have experienced violent or abusive trauma, a large proportion report problematic alcohol use or other substance misuse.(Source)

Several factors help explain the strong connection between PTSD and addiction:

• Temporary relief from symptoms. Alcohol, sedatives, opioids, and other substances can briefly reduce anxiety, numb emotional pain, or help with sleep. However, as the effects wear off, PTSD symptoms often return more intensely, leading to repeated use and increasing tolerance.(Source)


• Changes in brain chemistry. PTSD is associated with changes in stress hormones and neurotransmitters such as serotonin and norepinephrine, which affect mood, arousal, and the body’s “fight-or-flight” response.(Source) Substance use also alters these systems, which can make both conditions more severe and harder to treat.


• Overlapping symptoms. PTSD and addiction share symptoms like sleep problems, irritability, concentration difficulties, and emotional numbing. This overlap can make it difficult to tell where one condition ends and the other begins, and each can mask or worsen the other.(Source)


• Increased risk-taking and exposure to trauma. Substance use can increase the risk of accidents, violence, and other traumatic events, which may trigger new PTSD symptoms or aggravate existing ones.(Source)

When PTSD and substance use occur together, they tend to be more severe than either condition alone. People with both conditions are more likely to experience relationship problems, physical health issues, unemployment, and legal or financial difficulties.(Source) Because of this, it is essential to address PTSD and addiction at the same time through integrated, specialized care.

People living with PTSD may turn to a variety of substances in an attempt to manage their symptoms. Some of the most commonly misused substances include:

• Alcohol: Often used to “take the edge off,” fall asleep, or temporarily escape from distressing thoughts and feelings. Heavy drinking can worsen depression, anxiety, and sleep quality over time.(Source)


• Prescription sedatives or anti-anxiety medications: Medications such as benzodiazepines may be prescribed short-term for severe anxiety or insomnia, but they carry a risk of dependence and are generally not recommended as a long-term treatment for PTSD.(Source)


• Opioids: Prescription pain medications or illicit opioids may be used to numb both physical and emotional pain. Opioid misuse significantly increases the risk of overdose and can intensify depression and suicidal thoughts.(Source)


• Stimulants: Substances like cocaine or methamphetamine may be used to counteract emotional numbness or fatigue, but they can increase paranoia, agitation, and cardiovascular risks.(Source)


• Cannabis and other substances: Some people use cannabis to help with sleep or anxiety, but heavy or frequent use can interfere with memory, motivation, and mood, and may complicate PTSD treatment.(Source)

While substances may seem to offer short-term relief, they do not resolve the underlying trauma and often create additional problems. Over time, the brain adapts to regular substance use, leading to tolerance, dependence, and addiction.(Source) Effective treatment focuses on healthier, evidence-based ways to manage PTSD symptoms and build long-term resilience.

When someone is living with both PTSD and a substance use disorder, this is known as a co-occurring disorder or dual diagnosis.(Source) Treating only one condition—such as focusing on addiction while ignoring PTSD—often leads to relapse, because the untreated trauma continues to drive substance use.(Source)

Dual diagnosis treatment addresses PTSD and addiction together in a coordinated, integrated way. Key elements of effective dual diagnosis care include:

• Comprehensive assessment: A thorough evaluation of mental health history, trauma exposure, substance use patterns, medical conditions, and social support helps create a personalized treatment plan.(Source)


• Integrated care team: Mental health clinicians, addiction specialists, medical providers, and support staff work together to address both conditions at the same time.


• Trauma-informed environment: Staff are trained to recognize the impact of trauma and to create a safe, respectful, and predictable setting that reduces the risk of re-traumatization.(Source)


• Evidence-based therapies: Treatments with strong research support for PTSD and substance use disorders are combined and tailored to the individual.


• Relapse prevention and aftercare: Ongoing support, coping skills, and community resources help maintain recovery after formal treatment ends.

People with co-occurring PTSD and substance use disorders who receive integrated treatment generally have better outcomes, including reduced substance use, fewer PTSD symptoms, and improved quality of life.(Source)

At Cardinal Recovery, we use evidence-based therapies that are shown to help people recover from PTSD and substance use disorders. Your treatment plan is tailored to your unique history, symptoms, and goals.

Some of the most effective therapies for PTSD and co-occurring addiction include:

• Cognitive Behavioral Therapy (CBT): CBT helps you identify and change unhelpful thoughts and behaviors that keep you stuck in cycles of fear, shame, or substance use.(Source) The National Center for PTSD and other expert organizations recognize trauma-focused CBT as a first-line treatment for PTSD.(Source)


• Trauma-Focused CBT Approaches: These therapies, such as Cognitive Processing Therapy (CPT) and Prolonged Exposure (PE), are specifically designed to help people process traumatic memories, reduce avoidance, and challenge negative beliefs related to the trauma.(Source)


• EMDR (Eye Movement Desensitization and Reprocessing): EMDR is a structured therapy that uses guided eye movements or other forms of bilateral stimulation while you recall aspects of the traumatic event.(Source) Over time, this process can help the brain reprocess traumatic memories so they become less distressing and feel more like part of your past rather than your present.


• Dialectical Behavior Therapy (DBT) skills: DBT-based skills training can be especially helpful for people who struggle with intense emotions, self-harm, or impulsive behaviors. Skills such as mindfulness, distress tolerance, and emotion regulation support both PTSD recovery and sobriety.(Source)


• Medication management: Certain medications, including specific antidepressants, can reduce PTSD symptoms such as anxiety, intrusive thoughts, and depression, and may also support recovery from substance use disorders when used appropriately.(Source) Medication decisions are made collaboratively with a licensed prescriber.


• Group and family therapy: Group therapy offers connection with others who understand what you are going through, while family therapy can help loved ones learn how to support your recovery and heal from the impact of trauma and addiction.(Source)

Treatment is always paced to your readiness and comfort level. You do not have to share details of your trauma before you feel safe and supported. Our goal is to help you build skills, reduce symptoms, and regain a sense of control over your life.

The right level of care depends on the severity of your PTSD symptoms, the substances you are using, your physical health, and your home environment. Many people benefit from moving through several levels of care as they progress in recovery.(Source)

Common levels of care include:

• Medical detoxification: For individuals who are physically dependent on alcohol, opioids, benzodiazepines, or other substances, medically supervised detox can help manage withdrawal symptoms safely and comfortably.(Source)


• Residential or inpatient treatment: In a structured, 24/7 setting, you can focus fully on healing from PTSD and addiction without the triggers and stresses of everyday life. Residential care is often recommended for people with severe symptoms, multiple relapses, or unsafe home environments.(Source)


• Partial hospitalization and intensive outpatient programs (PHP/IOP): These programs provide several hours of therapy and support most days of the week while allowing you to return home or to supportive housing in the evenings.(Source)


• Outpatient therapy and continuing care: Once you have stabilized, ongoing individual and group therapy, peer support groups, and medication management can help you maintain progress and prevent relapse.

At Cardinal Recovery, we will work with you to determine which level of care best fits your needs and to create a step-down plan that supports long-term recovery.

It may be time to seek professional help if you notice any of the following:

• PTSD symptoms lasting longer than one month or getting worse over time


• Using alcohol or drugs to fall asleep, calm down, or “get through the day”


• Needing more of a substance to feel the same effect, or feeling unwell when you try to cut back


• Withdrawing from friends, family, work, or activities you used to enjoy
