Dual Diagnosis Treatment
What is Dual Diagnosis?
Dual diagnosis, also called co-occurring disorders, refers to the simultaneous presence of a mental health disorder and a substance use disorder. These conditions interact in complex ways, each influencing and often worsening the other.
The Prevalence of Co-Occurring Disorders
According to SAMHSA's 2019 National Survey on Drug Use and Health, approximately 9.5 million U.S. adults (3.8% of all adults) experienced both a mental illness and substance use disorder in the past year. However, the actual numbers are likely higher due to underdiagnosis and underreporting.
Among people seeking treatment for substance use disorders, 37-50% have a co-occurring mental health condition. Conversely, among those with severe mental illness, approximately 50% also have a substance use disorder. These high rates of co-occurrence are not coincidental—the conditions share common risk factors and biological vulnerabilities, and each condition increases risk for the other.
Why Do These Conditions Co-Occur?
Shared Risk Factors: Genetic vulnerabilities, brain chemistry abnormalities, early childhood trauma, chronic stress, and environmental factors increase risk for both conditions.
Self-Medication: People with mental health conditions often use substances to cope with distressing symptoms, temporarily relieving anxiety, depression, psychosis, or emotional pain. While this provides short-term relief, it worsens conditions long-term.
Substance-Induced Symptoms: Chronic substance use can cause or exacerbate mental health symptoms. Stimulants can trigger anxiety or psychosis; alcohol worsens depression; withdrawal causes severe mood disturbance.
Bidirectional Interaction: Each condition makes the other worse, creating a vicious cycle that is difficult to break without integrated treatment.
Frequently Co-Occurring Disorders
Depression & Substance Use
Major Depressive Disorder + Alcohol/Opioid Use
Depression and substance use have a complex bidirectional relationship. People with depression are twice as likely to develop substance use disorders. Alcohol is a depressant that worsens depressive symptoms despite providing temporary relief. Opioids are commonly used to numb emotional pain.
Treatment needs: Antidepressant medication (SSRIs/SNRIs), cognitive-behavioral therapy for depression, behavioral activation, addressing both conditions simultaneously to break the self-medication cycle.
Anxiety Disorders & Substance Use
GAD, Panic, Social Anxiety + Alcohol/Benzodiazepines
Approximately 20% of people with anxiety disorders have substance use disorders. Alcohol and benzodiazepines provide rapid anxiety relief but cause rebound anxiety, tolerance, and dependence. Stimulant use can trigger or worsen anxiety and panic.
Treatment needs: Non-addictive anti-anxiety medications (SSRIs, buspirone), cognitive-behavioral therapy, exposure therapy, teaching healthy anxiety management without substances.
Bipolar Disorder & Substance Use
Bipolar I/II + Alcohol/Stimulants/Marijuana
Over 50% of people with bipolar disorder develop substance use disorders. Substances may be used to self-medicate depression, manage racing thoughts, or enhance manic states. Substance use severely destabilizes mood and interferes with mood stabilizer effectiveness.
Treatment needs: Mood stabilizers (lithium, anticonvulsants, antipsychotics), addressing addiction while maintaining mood stability, psychoeducation about the interaction between substances and mood instability.
PTSD & Substance Use
Post-Traumatic Stress Disorder + Various SUDs
50-66% of people with PTSD develop substance use disorders, using substances to numb trauma memories, reduce hyperarousal, or facilitate sleep. Substance use prevents natural trauma processing and increases exposure to new traumatic events.
Treatment needs: Trauma-focused therapy (EMDR, CPT, PE), PTSD medications (SSRIs, prazosin), integrated trauma and addiction treatment, teaching healthy trauma coping strategies.
Schizophrenia & Substance Use
Schizophrenia/Schizoaffective + Marijuana/Stimulants
30-50% of people with schizophrenia have substance use disorders. Marijuana and stimulants can trigger or worsen psychotic symptoms. Substance use dramatically decreases medication adherence and treatment effectiveness, increasing hospitalization rates.
Treatment needs: Antipsychotic medication management, motivational interventions for substance use, intensive case management, integrated treatment teams familiar with serious mental illness.
ADHD & Substance Use
Attention-Deficit/Hyperactivity Disorder + Stimulants/Marijuana
People with ADHD have higher rates of substance use disorders, often beginning substance use at earlier ages. Untreated ADHD symptoms (impulsivity, difficulty with delayed gratification) increase addiction risk. Some misuse prescribed stimulants or use other substances to self-medicate.
Treatment needs: ADHD treatment with non-stimulant medications (atomoxetine, bupropion) or carefully monitored stimulants, behavioral interventions, organizational skills training, addressing impulsivity in both conditions.

The Importance of Professional Assessment
Distinguishing between substance-induced symptoms (which resolve with abstinence) and independent mental health conditions (which persist during sobriety) requires professional clinical expertise. Our comprehensive dual diagnosis assessment includes psychiatric evaluation, substance use assessment, medical examination, psychological testing when indicated, and observation during early abstinence to clarify diagnoses and guide treatment planning.
Our Dual Diagnosis Treatment Approach
Integrated treatment—addressing mental health and addiction simultaneously within a unified program—produces significantly better outcomes than treating conditions separately.
Comprehensive Dual Diagnosis Assessment
Treatment begins with thorough evaluation of both conditions using validated assessment tools including:
Addiction Severity Index (ASI): Comprehensive assessment across seven life domains including psychiatric status and substance use.
Psychiatric Diagnostic Interview: Detailed evaluation using DSM-5 criteria to identify all mental health conditions.
Screening Tools: PHQ-9 (depression), GAD-7 (anxiety), PCL-5 (PTSD), MDQ (bipolar), AUDIT (alcohol), DAST (drugs).
Medical Evaluation: Physical examination, laboratory tests, assessment of medical complications from both conditions.
Observation Period: Monitoring during early abstinence to distinguish substance-induced symptoms from independent mental health conditions.
Integrated Medication Management
Our psychiatric providers offer coordinated pharmacotherapy addressing both conditions:
For Mental Health: Antidepressants (SSRIs, SNRIs), mood stabilizers (lithium, anticonvulsants), antipsychotics, non-addictive anti-anxiety medications (buspirone, hydroxyzine), ADHD medications (non-stimulant options preferred), and sleep medications when appropriate.
For Addiction: Medication-assisted treatment for opioid use disorder (buprenorphine, methadone, naltrexone), medications for alcohol use disorder (naltrexone, acamprosate, disulfiram), and management of withdrawal and cravings.
Careful medication selection considers interactions, avoids potentially addictive medications when possible, and ensures psychiatric and addiction pharmacotherapies work synergistically rather than against each other.
Integrated Psychotherapy
Our therapists provide evidence-based treatments addressing both conditions simultaneously:
Cognitive-Behavioral Therapy: Addressing both mental health symptoms and addiction behaviors, identifying shared triggers, developing coping strategies for both conditions.
Dialectical Behavior Therapy (DBT): Particularly effective for borderline personality disorder, emotion dysregulation, and self-harm behaviors co-occurring with addiction.
Trauma-Focused Therapies: EMDR, CPT, or PE for co-occurring PTSD and addiction.
Motivational Interviewing: Enhancing motivation for change in both mental health management and addiction recovery.
Relapse Prevention: Recognizing how mental health symptoms trigger substance use cravings and developing integrated coping strategies.
Coordinated Treatment Planning
Unlike parallel treatment where addiction and mental health are addressed separately by different providers, our integrated model provides unified care with a single treatment team, coordinated treatment planning addressing both conditions, regular team communication ensuring all providers are aligned, treatment goals that recognize the interaction between conditions, and seamless transitions between levels of care.
This coordination ensures that mental health treatment supports rather than undermines addiction recovery, and vice versa. For example, psychiatric medications are selected to avoid addiction risk, therapy addresses how each condition affects the other, and crisis interventions consider both conditions.
Psychoeducation
Understanding both conditions and their interaction is essential for recovery. We provide comprehensive education about the neurobiology of addiction and mental illness, how substances affect mental health and vice versa, the importance of medication adherence for both conditions, recognizing early warning signs of relapse in both areas, and the chronic nature of both conditions requiring ongoing management.
Family members receive education about both conditions, how to support recovery, setting healthy boundaries, and recognizing crisis warning signs.
Case Management & Social Support
Dual diagnosis often involves complex practical needs. Our case managers assist with housing coordination and sober living placement, accessing disability benefits or employment support, connecting with community mental health resources, coordinating with outside providers (primary care, specialists), legal advocacy when needed, and family therapy and support services.
We facilitate connection to peer support including dual diagnosis-specific support groups, 12-step programs (with psychiatric medication acceptance), SMART Recovery, and alumni programming for sustained community and accountability.

Frequently Asked Questions
Dual diagnosis, also called co-occurring disorders, refers to the simultaneous presence of a mental health disorder and a substance use disorder. Common combinations include depression and alcohol use disorder, anxiety disorders and benzodiazepine dependence, bipolar disorder and stimulant use, PTSD and opioid addiction, and schizophrenia and marijuana use. According to SAMHSA's National Survey on Drug Use and Health, approximately 9.5 million U.S. adults (3.8% of all adults) had both a mental illness and substance use disorder in 2019. The co-occurrence is not coincidental—mental health conditions and addiction share underlying risk factors, each condition increases vulnerability to the other, and they interact in ways that worsen both conditions. Dual diagnosis requires integrated treatment addressing both conditions simultaneously rather than treating them separately or sequentially.
Integrated treatment—addressing mental health and substance use simultaneously within a coordinated program—produces significantly better outcomes than treating conditions separately or sequentially. Research consistently shows that integrated dual diagnosis treatment results in better treatment retention, reduced substance use, improved mental health symptoms, fewer hospitalizations and crisis interventions, better medication adherence, improved functioning and quality of life, and reduced overall healthcare costs. Treating addiction alone while ignoring mental health leads to relapse as untreated psychiatric symptoms drive continued substance use. Conversely, treating mental illness alone while ignoring addiction is ineffective as ongoing substance use interferes with psychiatric treatment, destabilizes mood, and prevents medication from working properly. Our integrated model provides unified treatment with a single team addressing both conditions through coordinated medication management, therapy addressing both conditions, and treatment planning that recognizes how the conditions interact.
The most frequently co-occurring combinations include: Depression and alcohol use disorder (alcohol worsens depression while depression increases drinking to self-medicate), Anxiety disorders and benzodiazepine or alcohol dependence (using sedatives to manage anxiety leading to dependence), Bipolar disorder and stimulant or alcohol use (using stimulants during depression, alcohol during mania, or substances to self-medicate mood instability), PTSD and various substance use disorders (50-66% of people with PTSD develop SUDs, often using substances to numb trauma symptoms), Schizophrenia and marijuana or stimulant use (30-50% of people with schizophrenia have SUDs), ADHD and stimulant misuse or other substance use (using substances to manage ADHD symptoms or misusing prescribed stimulants), and Borderline Personality Disorder and various SUDs (emotional dysregulation driving substance use for emotional regulation). Each combination requires specialized integrated treatment protocols addressing the unique interaction between specific conditions.
Dual diagnosis should be considered if you experience persistent mental health symptoms that continue during periods of sobriety, used substances initially to cope with mental health symptoms, have mental health symptoms that worsen during or after substance use, received mental health treatment that was ineffective while actively using substances, have family history of both mental illness and addiction, experience rapid mood swings, severe depression, anxiety, psychosis, or suicidal thoughts, or find your substance use and mental health symptoms feed into each other in a vicious cycle. Professional assessment is essential for accurate diagnosis as distinguishing between substance-induced symptoms (which resolve with abstinence) and independent mental health conditions (which persist during sobriety) requires clinical expertise and often several weeks of observation. Our comprehensive dual diagnosis assessment includes psychiatric evaluation using validated diagnostic tools, substance use history and assessment, medical examination, review of previous treatment, psychological testing when indicated, and observation during early abstinence to distinguish substance-induced from independent symptoms.
No—properly integrated treatment actually makes sustained sobriety easier by addressing the underlying mental health issues driving substance use. Many people use substances to self-medicate untreated or inadequately treated mental health conditions. When psychiatric symptoms like depression, anxiety, PTSD, or mood instability go untreated, they create powerful cravings and relapse triggers. Effective mental health treatment—including appropriate psychiatric medication and evidence-based therapy—removes one of the primary drivers of substance use. Research shows that people receiving integrated dual diagnosis treatment have better substance use outcomes than those receiving addiction treatment alone. The key is using the right treatments: non-addictive psychiatric medications (SSRIs, SNRIs, mood stabilizers, etc.) rather than potentially addictive ones (benzodiazepines), evidence-based psychotherapy addressing both conditions, and coordinated care ensuring addiction and mental health treatments work together rather than against each other. Our integrated approach ensures mental health treatment supports rather than undermines recovery.
Comprehensive dual diagnosis assessment uses validated clinical tools including: The Addiction Severity Index (ASI) assessing severity across seven life domains including psychiatric status and substance use; AUDIT (Alcohol Use Disorders Identification Test) screening for problematic alcohol use; DAST (Drug Abuse Screening Test) identifying drug use problems; PHQ-9 (Patient Health Questionnaire) measuring depression severity; GAD-7 assessing generalized anxiety symptoms; PCL-5 (PTSD Checklist) screening for trauma symptoms; MDQ (Mood Disorder Questionnaire) screening for bipolar disorder; MINI (Mini International Neuropsychiatric Interview) structured diagnostic interview for psychiatric conditions; and clinician-administered diagnostic interviews based on DSM-5 criteria. These tools help identify co-occurring conditions, assess severity, guide treatment planning, and track progress. Our team uses comprehensive assessment protocols ensuring accurate diagnosis of both substance use and mental health conditions, as proper diagnosis is essential for effective treatment planning.
