PTSD Residential Treatment With Substance Use Disorder in Tennessee
Post-Traumatic Stress Disorder, or PTSD, can affect far more than memories of a traumatic event. It can change sleep, relationships, concentration, emotional regulation, physical stress responses, trust, behavior, and a person’s sense of safety even after the original danger has passed.
Experiencing trauma can affect the body, mind, relationships, and everyday functioning. For some people, alcohol or drugs become a way to sleep, numb painful memories, reduce hyperarousal, feel less afraid, disconnect from emotions, or avoid thinking about what happened. The short-term relief may reinforce continued substance use while withdrawal, intoxication, disrupted sleep, and the consequences of addiction can make PTSD symptoms more difficult to manage.
Brooks Healing Center provides integrated care for adults experiencing PTSD alongside substance use concerns. Located between Nashville and Chattanooga in Normandy, Tennessee, Brooks can provide substance-use detox and stabilization when appropriate, residential dual-diagnosis treatment, individualized behavioral therapy, psychiatric and medication support when clinically appropriate, and continued care through our Partial Hospitalization Program and recovery housing options.
Treatment begins by understanding the complete clinical picture. PTSD symptoms can overlap with withdrawal, stimulant intoxication, depression, panic, dissociation, bipolar disorder, substance-induced psychosis, sleep deprivation, traumatic brain injury, medications, and other mental-health or medical conditions. Effective treatment needs to distinguish those problems rather than assuming every symptom has the same cause.

Key Points About PTSD and Addiction
- PTSD is a trauma- and stressor-related disorder, not simply a normal emotional response to something difficult. A qualifying trauma, specific symptom patterns, duration, impairment, and other diagnostic requirements all matter. VA National Center for PTSD
- Most people who experience trauma do not develop PTSD. VA estimates that approximately 6% of U.S. adults will experience PTSD at some point during their lifetime. VA National Center for PTSD
- PTSD symptoms fall into four major groups: intrusive or re-experiencing symptoms, avoidance, negative changes in thoughts and mood, and changes in arousal or reactivity. VA National Center for PTSD
- PTSD and substance use disorders frequently occur together. A large national epidemiological study found that 44.6% of people with lifetime PTSD also met criteria for an alcohol use disorder or another substance use disorder. VA National Center for PTSD
- Having a substance use disorder does not automatically mean PTSD treatment must wait. Current VA/DoD guidance states that patients with PTSD and SUD can benefit from evidence-based treatment for both conditions. VA National Center for PTSD
- Trauma-informed care and trauma-focused therapy are not the same thing. Trauma-informed care shapes how treatment is delivered; trauma-focused therapies such as CPT, PE, and EMDR directly address traumatic memories, beliefs, and avoidance.
- Current PTSD guidelines place the strongest evidence behind Cognitive Processing Therapy, Prolonged Exposure, and EMDR. These trauma-focused therapies are recommended over medication as first-line PTSD treatment when clinically appropriate. VA National Center for PTSD
- Medication can still be useful. Sertraline, paroxetine, and venlafaxine have evidence for PTSD, while prazosin may be considered specifically for PTSD-associated nightmares. VA National Center for PTSD
- How Brooks helps: Brooks addresses PTSD symptoms and substance use together through integrated dual-diagnosis treatment, residential structure, trauma-informed care, individualized therapy, substance-use relapse prevention, medication support when appropriate, PHP, supportive housing, sober living, and continuing recovery planning.
PTSD & Dual-Diagnosis Treatment at a Glance
| Treatment Component | What It Addresses | When It May Be Important |
|---|---|---|
| Substance-Use Detox & Stabilization | Withdrawal, intoxication, sleep disruption, medical concerns, psychiatric symptoms, and determining how substances may be affecting PTSD symptoms. | When alcohol, benzodiazepines, opioids, or another substance requires structured withdrawal support before the longer-term clinical picture can be evaluated more clearly. |
| Residential Dual-Diagnosis Treatment | PTSD symptoms and substance-use patterns within a structured 24-hour recovery environment. | When relapse risk, PTSD symptoms, substance use, impaired functioning, or the recovery environment makes lower-intensity treatment difficult to maintain. |
| Trauma-Informed Behavioral Treatment | Safety, coping, emotional regulation, avoidance, triggers, relationships, cravings, and relapse prevention. | Throughout treatment while substance use and PTSD symptoms are being addressed together. |
| Psychiatric & Medication Support | Depression, anxiety, nightmares, sleep, mood symptoms, medication response, and other psychiatric needs. | When medication is clinically appropriate within the individualized treatment plan. |
| Partial Hospitalization Program (PHP) | Intensive daytime treatment with increasing independence outside clinical hours. | Following residential treatment or when substantial clinical structure is still needed. |
| Sober Living | Substance-free housing, routine, accountability, peer support, and increasing independence. | For eligible individuals who benefit from continued recovery structure after more intensive treatment. |
What Is Post-Traumatic Stress Disorder?
Post-Traumatic Stress Disorder is a mental-health condition that can develop after exposure to actual or threatened death, serious injury, sexual violence, or certain other qualifying traumatic events.
Exposure can occur through directly experiencing trauma, witnessing it, learning that a violent or accidental trauma happened to someone close, or repeated professional exposure to disturbing details, such as may occur among some first responders or other professionals. VA National Center for PTSD
PTSD is not simply the memory of something frightening. Someone with PTSD may continue to experience a strong sense of threat even when the immediate danger has ended.
Symptoms can affect:
- Sleep
- Concentration
- Memory
- Emotional regulation
- Relationships
- Trust
- Work
- Physical stress responses
- Ability to relax
- Substance use
- Sense of safety
- Everyday routines
The Brooks dual-diagnosis program approaches PTSD symptoms in the context of the person’s substance use, current functioning, psychiatric needs, and recovery environment rather than treating the diagnosis as an isolated label.
Trauma Does Not Automatically Mean PTSD
A traumatic event and Post-Traumatic Stress Disorder are not the same thing.
Many people experience significant distress after trauma. They may:
- Feel frightened
- Have difficulty sleeping
- Think repeatedly about what happened
- Feel angry
- Become more alert to danger
- Avoid reminders
- Have temporary difficulty concentrating
These responses can occur during the normal recovery period after trauma.
Most people improve with time and do not develop PTSD. Current VA estimates suggest that about 6 out of every 100 U.S. adults experience PTSD at some point in their lives even though trauma exposure itself is far more common. VA National Center for PTSD
PTSD becomes the appropriate diagnosis only when the complete clinical requirements are met.
What Are the Symptoms of PTSD?
The DSM-5-TR organizes adult PTSD symptoms into four major symptom groups. The actual diagnosis requires a particular combination of symptoms, but understanding the categories can help explain why PTSD looks so different from person to person. VA National Center for PTSD
Intrusion and Re-Experiencing Symptoms
Someone may feel as though the traumatic experience continues to intrude into the present through:
- Unwanted memories
- Recurring distressing dreams
- Flashbacks
- Intense emotional reactions to reminders
- Physical stress responses when something resembles the trauma
A reminder may be obvious, such as returning to the location where something happened, or seemingly unrelated until the connection becomes clearer.
Avoidance Symptoms
Avoidance can involve trying not to think or feel anything associated with the trauma.
Someone may avoid:
- Certain places
- People
- Conversations
- News
- Sounds
- Smells
- Situations
- Thoughts
- Feelings
- Activities connected with the experience
Avoidance can temporarily lower distress, which makes the behavior feel useful.
Over time, however, a person’s world may become increasingly restricted.
Negative Changes in Thoughts and Mood
PTSD can affect the way someone interprets themselves, other people, and the world.
Symptoms can include:
- Persistent guilt or shame
- Excessive blame
- Feeling detached from other people
- Loss of interest in previously meaningful activities
- Difficulty experiencing positive emotions
- Persistent fear, anger, or sadness
- Negative beliefs about oneself
- Negative beliefs about safety or trust
- Difficulty remembering important aspects of the traumatic experience
These changes can contribute to isolation and may make alcohol or drugs feel like one of the few ways to temporarily escape painful thoughts.
Changes in Arousal and Reactivity
The body’s threat system can remain highly activated.
Symptoms may include:
- Hypervigilance
- Being easily startled
- Irritability
- Angry outbursts
- Difficulty sleeping
- Difficulty concentrating
- Reckless behavior
- Self-destructive behavior
- Feeling constantly “on edge”
Alcohol, stimulants, benzodiazepines, cannabis, and other substances can further complicate these symptoms because intoxication and withdrawal can affect sleep, arousal, judgment, anxiety, and mood.
How Long Do PTSD Symptoms Have to Last?
PTSD symptoms must persist for more than one month and create clinically significant distress or impairment.
Symptoms also cannot be better explained by a medication, substance use, or another medical condition. VA National Center for PTSD
That last point is especially important in dual-diagnosis treatment.
Someone actively withdrawing from alcohol, benzodiazepines, opioids, stimulants, or another drug may experience:
- Nightmares
- Anxiety
- Insomnia
- Irritability
- Concentration problems
- Hyperarousal
- Depression
- Paranoia
Those symptoms may overlap with PTSD without necessarily proving that PTSD is present.
Acute Stress Disorder vs. PTSD
Acute Stress Disorder, or ASD, can occur during the first month after a traumatic experience.
It shares many symptoms with PTSD but differs partly in timing and diagnostic structure.
Acute Stress Disorder: symptoms occur from approximately 3 days to 1 month after trauma.
PTSD: qualifying symptoms persist beyond one month.
Someone can develop PTSD without first meeting criteria for Acute Stress Disorder, and having ASD does not guarantee that PTSD will later develop. VA National Center for PTSD
This distinction prevents normal early trauma reactions from automatically being labeled chronic PTSD.
How Is PTSD Diagnosed?
There is no blood test, brain scan, or single online questionnaire that independently diagnoses PTSD.
A qualified clinician considers:
- The traumatic event
- Intrusion symptoms
- Avoidance
- Changes in thinking and mood
- Hyperarousal and reactivity
- Duration
- Functional impairment
- Substance use
- Withdrawal
- Medications
- Medical conditions
- Depression
- Anxiety
- Psychosis
- Dissociation
- Previous trauma
- Suicide and safety risk
What Is the PCL-5?
The PTSD Checklist for DSM-5, or PCL-5, is a 20-item self-report questionnaire commonly used to assess PTSD symptoms, screen for probable PTSD, and monitor changes over time.
It can be useful, but it is not the same thing as a full diagnostic evaluation.
The VA describes the Clinician-Administered PTSD Scale for DSM-5, or CAPS-5, as the gold-standard structured interview for PTSD diagnosis. VA National Center for PTSD
A screening score should therefore prompt further evaluation rather than being treated as proof of a diagnosis.
PTSD With Dissociative Symptoms
Some people with PTSD experience significant dissociation.
This can include:
Depersonalization: feeling detached from oneself or as though one is observing oneself from outside the body.
Derealization: feeling as though the surrounding world is unreal, distant, dreamlike, or distorted.
The DSM-5-TR includes a dissociative PTSD specifier for these experiences. VA National Center for PTSD
Dissociation can also occur with certain substances and psychiatric conditions, which makes careful assessment important when active drug use is present.
PTSD vs. Complex PTSD: What Is the Difference?
PTSD and Complex PTSD, often abbreviated C-PTSD, have considerable overlap but are not identical diagnostic concepts.
Complex PTSD is most often associated with prolonged or repeated trauma, particularly trauma that occurs in relationships or circumstances where escape feels difficult. Examples may include prolonged abuse, captivity, trafficking, repeated interpersonal violence, or chronic childhood trauma.
C-PTSD includes core PTSD symptoms along with additional persistent difficulties involving:
- Emotional regulation
- Negative self-concept
- Relationships
There is an important diagnostic distinction: Complex PTSD is recognized as a separate diagnosis in the ICD-11 but is not a separate DSM-5-TR diagnosis. Clinicians working under DSM-5-TR may describe complex trauma presentations using PTSD and other relevant features or diagnoses. Cleveland Clinic
So the phrase “Complex PTSD” can be clinically meaningful without implying that it is a separate DSM-5-TR disorder.
How Common Is PTSD?
Current VA guidance estimates that approximately 6% of U.S. adults experience PTSD at some point during their lifetime.
Approximately 5% of adults may have PTSD during a given year, although prevalence varies according to population, trauma exposure, sex, military experience, methodology, and other factors. VA National Center for PTSD
Most people who experience trauma do not develop PTSD.
This distinction matters because trauma exposure alone should not be treated as a psychiatric diagnosis.
PTSD and Addiction
PTSD and substance use disorders commonly occur together.
A large national epidemiological study found that 44.6% of people with lifetime PTSD also met criteria for an alcohol use disorder or another substance use disorder. Among Veterans in the same research, lifetime PTSD was associated with twice the likelihood of alcohol use disorder and approximately three times the likelihood of a drug use disorder. VA National Center for PTSD
The VA also notes that people with both PTSD and SUD experience greater functional difficulty across medical, financial, legal, social, and psychiatric areas than people with either disorder alone. VA National Center for PTSD
Why PTSD and Substance Use Can Become Intertwined
Someone with PTSD may use alcohol or drugs to:
- Fall asleep
- Stop nightmares
- Numb memories
- Reduce hypervigilance
- Feel less anxious
- Avoid painful emotions
- Feel comfortable around other people
- Suppress anger
- Escape feelings of guilt or shame
- Temporarily feel detached from the trauma
This pattern is often described as self-medication.
The short-term relief can reinforce substance use, but the long-term effects may include:
- Dependence
- Withdrawal
- Worse sleep
- Increased anxiety
- Depression
- Greater irritability
- Relationship problems
- Isolation
- Financial stress
- Reduced emotional regulation
- Increased exposure to risky situations
The VA notes that substance use can worsen PTSD symptoms and that people with co-occurring PTSD and SUD also face higher risks of depression, anxiety, and suicide. VA National Center for PTSD
Does PTSD Cause Addiction?
PTSD does not automatically cause a substance use disorder.
Many people with PTSD never develop addiction.
PTSD may, however, create symptoms that make alcohol or drugs feel useful in the short term. Repeatedly using substances to sleep, reduce anxiety, numb emotions, or avoid memories can eventually contribute to dependence or addiction.
The relationship can also work in the opposite direction.
Alcohol or drug use can increase exposure to:
- Accidents
- Violence
- Assault
- Dangerous environments
- Serious injuries
Those events can themselves become traumatic.
The relationship between PTSD and addiction is therefore often bidirectional rather than a simple one-way cause-and-effect relationship. VA National Center for PTSD
Alcohol and PTSD
Alcohol is commonly used to reduce anxiety or help with sleep.
It may feel calming initially, but repeated drinking can disrupt restorative sleep, contribute to withdrawal-related anxiety, increase impulsivity, worsen relationships, and make PTSD symptoms more difficult to manage.
Someone may move from:
“Alcohol helps me sleep.”
to:
“I cannot sleep unless I drink.”
and eventually:
“When I stop drinking, my anxiety and sleep become even worse.”
When physical alcohol dependence develops, treatment may need to begin with medical alcohol detox before longer-term PTSD and addiction treatment continues.
Benzodiazepines and PTSD
Benzodiazepines can rapidly reduce anxiety and are legitimate medications for selected conditions.
However, current PTSD treatment guidelines recommend against benzodiazepines as a PTSD treatment because of limited evidence of benefit and concerns including dependence, cognitive effects, and other risks. VA National Center for PTSD
This is particularly relevant for someone with a substance-use disorder.
A person already physically dependent on Xanax, Ativan, Klonopin, Valium, or another benzodiazepine should not stop abruptly, because withdrawal can itself become medically dangerous.
Brooks provides additional guidance on benzodiazepine addiction and withdrawal.
Cannabis and PTSD
Some people use marijuana in an attempt to manage anxiety, insomnia, nightmares, or intrusive memories.
Current VA guidance does not recommend cannabis or cannabis-derived products as evidence-based PTSD treatment. VA National Center for PTSD
Cannabis may also cause or worsen:
- Anxiety
- Paranoia
- Sleep disruption
- Cognitive problems
- Cannabis use disorder
- Withdrawal
Someone with PTSD and problematic marijuana use therefore needs assessment of both issues rather than simply assuming marijuana is functioning as treatment.
Stimulants and PTSD
Cocaine, methamphetamine, and prescription stimulant misuse can intensify symptoms that already overlap with PTSD.
Stimulants may increase:
- Hypervigilance
- Insomnia
- Startle response
- Anxiety
- Irritability
- Paranoia
- Agitation
Someone who is sleep deprived and actively using stimulants may appear extremely hyperaroused even when some of those symptoms are being driven by intoxication rather than PTSD alone.
Opioids and PTSD
Opioids may be used to numb both physical and emotional pain.
For someone with trauma-related symptoms, the temporary emotional detachment produced by opioid intoxication can become reinforcing.
As opioid use disorder develops, withdrawal, cravings, overdose experiences, unstable routines, isolation, and loss can create additional trauma and emotional distress.
Brooks’ opioid addiction treatment addresses opioid use within the broader behavioral and mental-health context of recovery.
Substance-Induced Symptoms vs. PTSD
Substance use can imitate or intensify many PTSD symptoms.
For example:
Stimulants can produce:
- Hypervigilance
- Paranoia
- Insomnia
- Agitation
- Risky behavior
Alcohol or sedative withdrawal can produce:
- Anxiety
- Tremor
- Insomnia
- Hyperarousal
- Hallucinations in severe cases
Cannabis can produce:
- Paranoia
- Anxiety
- Derealization
- Cognitive changes
Hallucinogens and dissociative drugs can produce:
- Perceptual disturbances
- Dissociation
- Fear
- Altered sense of reality
The DSM-5-TR specifically requires that PTSD symptoms not be better explained by a substance or another medical condition. VA National Center for PTSD
Someone can also have both PTSD and substance-induced worsening of PTSD-like symptoms, which is one reason stabilization can be clinically valuable.
PTSD Treatment and Substance Use Can Occur at the Same Time
Older models sometimes assumed that someone needed prolonged sobriety before trauma-related treatment could begin.
Current evidence does not support a blanket requirement that PTSD treatment must always wait until a substance use disorder is completely resolved.
The VA National Center for PTSD states that patients with co-occurring PTSD and SUD can tolerate and benefit from evidence-based trauma-focused psychotherapy and that having one disorder should not prevent treatment of the other. VA National Center for PTSD
Research comparing treatment approaches has also found that integrated or concurrent trauma-focused PTSD treatment combined with substance-use treatment can produce greater improvements in PTSD symptoms than substance-use treatment alone. VA National Center for PTSD
The appropriate timing still depends on safety, withdrawal, psychiatric stability, treatment readiness, and the specific therapy being considered.
Trauma-Informed Care vs. Trauma-Focused Therapy
These terms are frequently used as though they mean the same thing.
They do not.
What Is Trauma-Informed Care?
Trauma-informed care is a framework for how care is delivered.
It recognizes that traumatic experiences may affect:
- Trust
- Emotional regulation
- Reactions to authority
- Personal boundaries
- Medical procedures
- Relationships
- Physical touch
- Safety
A trauma-informed environment emphasizes principles such as:
- Safety
- Transparency
- Collaboration
- Choice
- Respect
- Avoiding unnecessary retraumatization
Brooks incorporates Trauma-Informed Therapy when clinically appropriate within individualized dual-diagnosis treatment.
What Is Trauma-Focused Therapy?
Trauma-focused therapy is more specific.
It directly targets traumatic memories, trauma-related beliefs, avoidance, and other mechanisms maintaining PTSD.
The 2023 VA/DoD Clinical Practice Guideline gives its strongest psychotherapy recommendation to three individual trauma-focused treatments:
- Cognitive Processing Therapy (CPT)
- Prolonged Exposure (PE)
- Eye Movement Desensitization and Reprocessing (EMDR)
These are currently among the most strongly supported PTSD treatments. VA National Center for PTSD
Trauma-informed care is valuable, but simply creating a trauma-sensitive environment is not identical to providing one of the guideline-recommended PTSD-specific trauma therapies.
That distinction matters when developing longer-term treatment plans.
Cognitive Processing Therapy, Prolonged Exposure, and EMDR
Cognitive Processing Therapy
Cognitive Processing Therapy helps patients identify and examine trauma-related beliefs about:
- Safety
- Trust
- Power
- Control
- Esteem
- Intimacy
- Blame
The goal is not to convince someone that the trauma was harmless. It is to address beliefs that keep the traumatic event controlling the present.
Prolonged Exposure
Prolonged Exposure helps patients gradually and systematically approach traumatic memories and safe reminders that have been avoided.
Avoidance reduces distress temporarily but can keep the brain from learning that a traumatic event is over and that not every reminder represents current danger.
EMDR
Eye Movement Desensitization and Reprocessing uses structured trauma processing alongside bilateral stimulation.
EMDR is one of the trauma-focused treatments recommended by current VA/DoD PTSD guidelines. VA National Center for PTSD
Brooks’ current program includes trauma-informed therapy, CBT, DBT, experiential therapy, and Brainspotting. Ask admissions about current availability of specific trauma-focused therapies. Continuing-care planning can account for additional PTSD-specific treatment needs.
Therapy for PTSD and Addiction at Brooks
Brooks uses individualized treatment planning to address substance use and appropriate co-occurring PTSD symptoms.
Cognitive Behavioral Therapy
Cognitive Behavioral Therapy can help patients recognize relationships among:
- Thoughts
- Emotions
- Trauma reminders
- Avoidance
- Substance use
- Cravings
- Behavior
CBT can also strengthen coping and relapse-prevention skills when distress triggers the urge to drink or use drugs.
Dialectical Behavior Therapy
Dialectical Behavior Therapy emphasizes:
- Emotional regulation
- Distress tolerance
- Mindfulness
- Interpersonal effectiveness
These skills may be particularly useful when trauma symptoms lead to emotional flooding, impulsive substance use, relationship conflict, or difficulty tolerating distress without escaping through alcohol or drugs.
Experiential Therapy
Experiential Therapy can provide structured opportunities to work on emotions, coping, communication, relationships, and self-awareness outside traditional talk therapy.
Brainspotting
Brainspotting Therapy may be incorporated when clinically appropriate as one component of an individualized treatment plan.
Brainspotting does not have the same guideline status as CPT, PE, or EMDR for PTSD. It may be used as an additional modality according to patient needs and clinician judgment.
12-Step Recovery Support
12-Step Recovery Support can provide peer connection, structure, accountability, and continued recovery support alongside formal clinical treatment.
Mutual-help programs do not directly treat PTSD, but many people with co-occurring PTSD and SUD use them as part of a broader recovery plan. VA National Center for PTSD
Medication for PTSD
Medication may be incorporated into PTSD treatment when clinically appropriate.
Current VA/DoD guidance recommends trauma-focused psychotherapy over medication when either treatment is available and appropriate, but several medications have evidence for reducing PTSD symptoms. VA/DoD guideline
Sertraline and Paroxetine
Sertraline and paroxetine are SSRIs with FDA indications for PTSD and are among the medications with the strongest evidence in current VA/DoD guidance. VA National Center for PTSD
Medication response varies, and these medications generally require consistent use over time rather than producing immediate relief.
Venlafaxine
The SNRI venlafaxine also has substantial evidence supporting its use in PTSD and is recommended by current VA/DoD guidance, although it is not FDA approved specifically for PTSD. VA National Center for PTSD
Prazosin for PTSD Nightmares
Prazosin may be considered specifically for PTSD-associated nightmares.
Current guidance distinguishes this use from treating overall PTSD symptoms; the evidence supports prazosin primarily for nightmares rather than as a broad PTSD medication. VA National Center for PTSD
Benzodiazepines Are Not Recommended as PTSD Treatment
Benzodiazepines can rapidly reduce anxiety, but current VA/DoD PTSD guidance recommends against them as PTSD treatment.
For someone with co-occurring addiction, concerns about tolerance, physical dependence, overdose risk, and withdrawal become especially important. VA National Center for PTSD
Someone who is already physically dependent on benzodiazepines should not stop suddenly.
PTSD, Sleep, and Nightmares
Sleep problems are among the most common and disruptive PTSD symptoms.
Someone may:
- Delay going to sleep
- Fear having nightmares
- Wake suddenly in panic
- Sleep lightly
- Check doors or windows repeatedly
- Remain alert for danger
- Use alcohol or sedatives to force sleep
This creates an especially difficult cycle when substances become part of the sleep routine.
Someone may initially drink because it helps them fall asleep, but alcohol can reduce restorative sleep and eventually produce withdrawal-related insomnia and anxiety.
Addressing sleep therefore becomes part of both PTSD recovery and substance-use relapse prevention.
Avoidance: One of the Engines That Can Keep PTSD Going
Avoidance is understandable.
A person learns that a certain memory, road, smell, conversation, or situation causes intense distress.
Avoiding it makes the distress decrease immediately.
The brain learns:
“Avoidance kept me safe.”
The problem is that the person’s life can gradually become smaller.
Someone may stop:
- Driving
- Going into crowds
- Seeing friends
- Sleeping alone
- Going to medical appointments
- Talking about what happened
- Leaving home
Alcohol or drugs can become another avoidance strategy.
Rather than avoiding the situation itself, someone learns:
“I can only deal with this if I drink first.”
Effective PTSD treatment often involves helping people safely reduce avoidance and relearn that reminders of trauma are not necessarily current threats.
PTSD Triggers and Substance-Use Triggers Can Overlap
A trigger can activate trauma symptoms and substance cravings almost simultaneously.
Examples might include:
- An argument
- A smell
- A particular date
- Driving past a certain location
- Physical pain
- A news story
- Sexual intimacy
- A crowded room
- A loud noise
- Feeling rejected
- A nightmare
Someone may experience a flashback or intense anxiety and then immediately crave alcohol, opioids, marijuana, or another substance.
Dual-diagnosis treatment can help patients learn to identify this sequence earlier:
Trigger → trauma response → craving → substance use
and develop alternatives before the cycle reaches the final step.
Residential PTSD Treatment With Substance Use Disorder
Residential treatment can provide a period of structure away from environments where trauma symptoms and substance use have become deeply connected.
Brooks’ residential treatment program provides a 24-hour recovery environment for clinically appropriate adults with substance use and co-occurring mental-health needs.
Residential care may be useful when PTSD and addiction have disrupted:
- Sleep
- Relationships
- Daily routine
- Employment
- Medication consistency
- Ability to remain abstinent
- Emotional regulation
- Treatment attendance
- Recovery support
- Safety
The benefit is not simply “getting away from triggers.” Avoiding every reminder forever is generally not the goal of evidence-based PTSD treatment.
Residential structure creates time to stabilize substance use, strengthen coping, begin behavioral treatment, improve sleep and routine, and develop a longer-term plan for treating trauma safely.
Medical Detox and PTSD
When someone with PTSD is physically dependent on alcohol, benzodiazepines, opioids, or another substance, treatment may begin with medical detox and stabilization.
Detox does not treat PTSD itself.
It can create a medically safer period in which clinicians observe:
- Withdrawal
- Anxiety
- Sleep
- Nightmares
- Mood
- Psychosis
- Dissociation
- Suicidal thoughts
- Current psychiatric medications
- How symptoms change as intoxication resolves
This can make the longer-term clinical picture clearer and help determine what treatment should happen next.
Benefits of Residential PTSD and Addiction Treatment
Residential treatment can provide a focused environment for recovery.
Potential benefits can include:
Greater stability: Consistent sleep, meals, clinical contact, and daily routine can help reduce the chaos often associated with active addiction.
Improved functioning: Treatment can help someone begin rebuilding concentration, communication, self-care, relationships, and everyday responsibility.
Stronger coping skills: Patients can practice alternatives to avoidance, impulsive behavior, and substance use.
Relapse-prevention planning: Trauma reminders and substance-use triggers can be identified together rather than treating them as unrelated problems.
Observation over time: A structured environment gives clinicians more opportunity to distinguish withdrawal, substance-induced symptoms, PTSD, depression, anxiety, and other psychiatric concerns.
Continuity of care: Appropriate patients can move from stabilization into residential care and later into structured step-down treatment without treating recovery as one isolated episode.
When PTSD Requires Emergency Help
PTSD itself is treatable, but some situations require immediate crisis intervention.
Seek urgent help when someone:
- Has suicidal intent or a suicide plan
- Has recently attempted suicide
- Cannot remain safe
- Is severely intoxicated and suicidal
- Is experiencing severe psychosis
- Cannot distinguish reality
- Has become dangerously aggressive or disorganized
- Is undergoing a medical emergency related to withdrawal or overdose
- Cannot care for basic needs
For a life-threatening emergency, call 911.
For suicidal thoughts or a mental-health crisis in the United States, call or text 988.
People with co-occurring PTSD and SUD face increased suicide-related risk, making direct safety assessment an important part of treatment. VA National Center for PTSD
Continuing Care After Residential PTSD Treatment
PTSD and substance-use recovery generally extend beyond one residential stay.
Continuing treatment may include:
- Individual psychotherapy
- Evidence-based trauma-focused treatment when appropriate
- Psychiatric follow-up
- Medication management
- Substance-use treatment
- Peer recovery support
- Sleep treatment
- Family support
- Relapse prevention
- Safety planning
- Structured housing
- Continued monitoring of PTSD symptoms
Partial Hospitalization Program
Brooks’ Partial Hospitalization Program provides intensive daytime clinical treatment for medically stable patients who continue to need substantial structure after residential care.
PHP can include therapy, recovery education, relapse-prevention planning, medication follow-up when appropriate, and continued treatment of co-occurring mental-health symptoms.
Eligible patients who need structured housing while participating in PHP may use Brooks’ supportive housing in Tullahoma.
Sober Living
For eligible individuals who no longer require intensive clinical treatment but continue to benefit from accountability and a substance-free recovery environment, Brooks provides sober living in Tullahoma.
A stable living environment can provide more time to practice coping and relapse-prevention skills while returning to work, relationships, finances, appointments, transportation, and everyday responsibilities.

Does Insurance Cover PTSD and Dual-Diagnosis Treatment?
Many commercial health insurance plans include behavioral-health and substance-use benefits, although exact coverage depends on the individual policy, diagnoses, medical necessity, recommended level of care, network status, deductible, coinsurance, and authorization requirements.
Brooks’ admissions team can verify your insurance benefits before admission and explain the information provided by your insurance carrier.
Insurance verification does not guarantee payment and should not be interpreted as confirmation that a particular insurer, Medicare, Medicaid, or another program will cover a specific admission.
Get Help for PTSD and Addiction in Tennessee
PTSD and substance use can reinforce one another in ways that make both problems difficult to manage independently. A person may use alcohol or drugs to avoid trauma symptoms, while dependence, withdrawal, disrupted sleep, relationship problems, and addiction-related consequences create even more distress.
Treatment can address both conditions together.
Brooks Healing Center provides integrated care for adults with co-occurring PTSD and substance use through stabilization when appropriate, residential treatment, trauma-informed behavioral care, individualized therapy, psychiatric and medication support when clinically appropriate, PHP, supportive housing, sober living, and continued recovery planning.
Frequently Asked Questions About PTSD Residential Treatment
What Is the Difference Between Trauma and PTSD?
Trauma refers to exposure to a deeply threatening or disturbing event.
PTSD is a specific mental-health diagnosis requiring qualifying trauma exposure, particular symptom patterns, symptoms lasting more than one month, and significant distress or impairment.
Most people who experience trauma do not develop PTSD. VA National Center for PTSD
Why Should I Consider PTSD and Addiction Treatment Together?
Substance use may become a way of managing nightmares, anxiety, hypervigilance, painful memories, or emotional numbness.
At the same time, intoxication, withdrawal, disrupted sleep, and addiction-related consequences can worsen PTSD symptoms.
Current VA guidance supports treating PTSD and substance use disorders concurrently rather than automatically delaying treatment of one until the other is completely resolved. VA National Center for PTSD
Can Someone Have PTSD Without Remembering Every Detail of the Trauma?
Yes.
PTSD can include difficulty recalling important aspects of a traumatic event.
Memory following trauma can also be affected by injury, dissociation, intoxication, stress, and other factors, so diagnosis is based on the complete clinical picture rather than whether someone can provide a perfectly detailed narrative. VA National Center for PTSD
Is Complex PTSD the Same as PTSD?
They overlap, but they are not identical diagnostic concepts.
Complex PTSD includes core PTSD symptoms along with persistent problems involving emotional regulation, negative self-concept, and relationships.
C-PTSD is recognized as a separate diagnosis in ICD-11 but is not a separate diagnosis in DSM-5-TR. Cleveland Clinic
What Is the Difference Between Trauma-Informed Care and Trauma-Focused Therapy?
Trauma-informed care is a framework emphasizing safety, collaboration, choice, and awareness of how trauma can affect treatment.
Trauma-focused therapy directly addresses traumatic memories, trauma-related beliefs, and avoidance.
Current PTSD guidelines place the strongest evidence behind trauma-focused treatments including CPT, PE, and EMDR. VA National Center for PTSD
What Are the Most Evidence-Based Therapies for PTSD?
The 2023 VA/DoD PTSD guideline gives its strongest recommendation to:
- Cognitive Processing Therapy
- Prolonged Exposure
- EMDR
These are individual trauma-focused psychotherapies with the strongest overall evidence for PTSD symptom reduction. VA National Center for PTSD
Other therapies may still play important roles in stabilization, coping, emotional regulation, trauma-informed care, and substance-use recovery.
Can PTSD Be Treated While Someone Is Recovering From Addiction?
Yes.
Research indicates that patients with PTSD and SUD can safely engage in and benefit from trauma-focused PTSD therapies while also receiving evidence-based substance-use treatment. VA National Center for PTSD
The exact timing and treatment plan depend on medical stability, withdrawal, safety, readiness, and available clinical services.
Does Someone Need to Be Completely Sober Before PTSD Therapy Begins?
Not necessarily.
A substance use disorder should not automatically prevent someone from receiving evidence-based PTSD treatment.
Withdrawal or acute medical instability may need to be addressed first, but current evidence supports concurrent or integrated PTSD/SUD treatment rather than requiring prolonged abstinence in every case. VA National Center for PTSD
What Medications Are Used for PTSD?
Sertraline and paroxetine have FDA indications for PTSD, and venlafaxine also has substantial evidence supporting its use.
Prazosin may be considered specifically for PTSD-associated nightmares.
Medication selection depends on symptoms, other diagnoses, medical history, current substance use, other prescriptions, side effects, and previous treatment response. VA National Center for PTSD
Are Benzodiazepines Recommended for PTSD?
Current VA/DoD guidance recommends against benzodiazepines as PTSD treatment.
This is especially important when addiction or physical dependence is already present. VA National Center for PTSD
Someone currently taking benzodiazepines regularly should not abruptly stop without appropriate medical guidance.
Does Marijuana Treat PTSD?
Current VA guidance does not recommend cannabis or cannabis-derived products as PTSD treatment because there is insufficient evidence supporting benefit and there are known risks associated with cannabis use disorder and other adverse effects. VA National Center for PTSD
How Long Does Residential PTSD and Addiction Treatment Last?
There is no single treatment duration that is appropriate for everyone.
Length of care depends on:
- Substance involved
- Withdrawal needs
- PTSD severity
- Psychiatric stability
- Safety
- Progress in treatment
- Recovery environment
- Insurance authorization
- Recommended level of care
Some patients transition from residential treatment into PHP and later into community-based therapy rather than treating recovery as one fixed 30- or 45-day episode.
Does Brooks Provide Trauma-Focused Therapy Like EMDR or Prolonged Exposure?
Current national PTSD guidelines identify CPT, PE, and EMDR as the most strongly supported PTSD-specific trauma-focused treatments.
Ask admissions about current availability of specific trauma-focused therapies. Brooks’ current program includes trauma-informed therapy, CBT, DBT, experiential therapy, Brainspotting, and substance-use treatment, while continuing-care planning can account for additional evidence-based PTSD-specific therapy needs.
Does Brooks Provide Residential PTSD and Addiction Treatment?
Yes.
Brooks provides residential dual-diagnosis treatment for clinically appropriate adults experiencing PTSD alongside substance use concerns between Nashville and Chattanooga in Normandy, Tennessee.
Treatment can address substance use, withdrawal or stabilization, PTSD symptoms, avoidance, emotional regulation, sleep, coping, relationships, medication needs, relapse prevention, and continuing-care planning.
Will Insurance Cover PTSD Residential Treatment in Tennessee?
Many commercial insurance plans include behavioral-health and substance-use treatment benefits, but exact coverage depends on the policy, diagnoses, medical necessity, network status, deductible, coinsurance, authorization requirements, and recommended level of care.
Brooks can verify insurance benefits before admission and explain the information returned by the insurance carrier.
