What Are Co-Occurring Disorders? Resources and Support in Washington State

What Are Co-Occurring Disorders (Dual Diagnosis)?

Co-occurring disorders — also called dual diagnosis — refer to the simultaneous presence of a mental health condition and a substance use disorder (SUD). These two things don't just happen to exist side by side. They're deeply intertwined.

Common combinations include:

• Depression + alcohol use — alcohol is a depressant, and people often use it to numb emotional pain, which deepens the depression over time
• PTSD or trauma + opioids — opioids blunt emotional and physical pain; survivors of violence, accidents, or abuse may turn to them to quiet overwhelming flashbacks and anxiety
• Anxiety disorders + benzodiazepines or cannabis — substances are used to manage the physical symptoms of anxiety, creating dependence
• Bipolar disorder + stimulant use — stimulants can mirror or trigger manic episodes; people in depressive phases may use them to feel functional
• Borderline personality disorder + any substance — emotional dysregulation drives substance use as a coping mechanism

According to the Substance Abuse and Mental Health Services Administration (SAMHSA), roughly 21.5 million adults in the U.S. have a co-occurring disorder. In Washington state, the behavioral health system has increasingly moved toward integrated care models that recognize this reality — but gaps still exist, and many people fall through the cracks when they're bounced between systems.

Why Co-Occurring Disorders Are Common Among Vulnerable Populations

Co-occurring disorders aren't distributed equally. They're significantly more prevalent among people experiencing domestic violence, homelessness, and single parenthood under extreme stress — the exact populations Bossplayah Haven serves.

Domestic violence survivors are at sharply elevated risk. Ongoing or past abuse creates chronic trauma that manifests as PTSD, depression, anxiety, and complex emotional dysregulation. Survivors often turn to substances to manage overwhelming emotional states — or their abusers may have used substances against them, controlling their access or forcing use. Leaving an abusive relationship doesn't erase the trauma; untreated, it grows into co-occurring disorders that make stabilization incredibly difficult.

People experiencing homelessness face compounding stressors — physical danger, lack of sleep, unstable food and shelter, exposure to violence, and severed social connections — all of which drive or worsen mental health conditions. Substance use becomes a survival tool: a way to stay awake, stay warm, numb fear, or belong to a social network. Housing instability and co-occurring disorders create a loop that's nearly impossible to break without integrated support.

Single mothers and single parents under extreme stress are another high-risk group. Financial insecurity, isolation, the impossible demands of raising children alone, exposure to unsafe relationships, and histories of childhood trauma converge in ways that destabilize mental health. Without a safety net, many turn to substances to keep going — and without integrated treatment, recovery is nearly impossible to sustain.

For all of these groups, sequential treatment (treating one disorder and then the other) doesn't work. The disorders are too interconnected. The life circumstances are too unstable. The key is simultaneous, integrated support.

Washington State Resources for Co-Occurring Disorders

Washington state has several programs, hotlines, and agencies dedicated to dual diagnosis and co-occurring mental health and substance use disorders. Here are the most important:

DSHS Division of Behavioral Health and Recovery (DBHR)

The Washington State Department of Social and Health Services (DSHS) houses the Division of Behavioral Health and Recovery (DBHR), which funds and oversees behavioral health services statewide — including substance use treatment, mental health services, and integrated care programs for people with co-occurring disorders. DBHR contracts with regional Behavioral Health Administrative Services Organizations (BH-ASOs) to connect people to services in their county. Start at dshs.wa.gov/bhsia/dbhr or call 360-725-2028.

Washington Recovery Help Line

Call or text: 866-789-1511 | Available 24/7. This free, confidential helpline provides crisis support and referrals for people struggling with mental health challenges, substance use, or both. Staffed by trained counselors who understand co-occurring disorders. If you're in crisis or just don't know where to start, this is the number to call.

SAMHSA's Washington State Treatment Locator

SAMHSA's Behavioral Health Treatment Services Locator at findtreatment.gov allows you to search for programs in Washington state that specifically treat co-occurring disorders. Filter by "Dual Diagnosis" or "Co-Occurring Mental and Substance Use Disorders" to find integrated treatment programs near you. Many programs listed accept Medicaid/Apple Health, making them accessible at low or no cost.

Crisis Connections (King County)

Call: 866-427-4747 | Available 24/7. If you're in King County (Seattle area), Crisis Connections provides 24/7 crisis support for mental health and substance use emergencies. They can dispatch mobile crisis teams and connect callers to integrated care resources. For Deaf/Hard of Hearing: TTY at 206-461-3219.

Community Mental Health Centers with Dual Diagnosis Programs

Washington's regional Community Mental Health Centers (CMHCs) are required to provide integrated behavioral health services, including dual diagnosis programs. Key providers include:

• Neighborcare Health (Seattle) — Integrated behavioral health with substance use treatment
• MultiCare Behavioral Health (Pierce, King, and surrounding counties)
• Sea Mar Community Health Centers — Bilingual, culturally responsive integrated care
• Compass Health (Snohomish, Skagit, Whatcom, San Juan, Island counties)
• Volunteers of America Western Washington — Housing, recovery, and integrated mental health

Search wa-recovery.org or the SAMHSA locator above for programs by county.

Washington State Peer Support Specialist Programs

Peer Support Specialists are people with lived experience of mental health challenges and/or substance use who are trained to support others in recovery. Washington has a robust statewide certification program through DBHR, and many dual diagnosis and integrated treatment programs embed peer specialists into their care teams. Peer support is particularly effective for co-occurring disorders because peers understand the complexity firsthand — and they offer hope that recovery is possible. Contact DBHR or your local BH-ASO to find peer support programs in your area.

Integrated Treatment vs. Sequential Treatment — What Works?

For decades, the default approach was sequential treatment: get sober first, then address your mental health. Or stabilize your mental health, then tackle the addiction. The logic seemed reasonable — but in practice, it failed most people.

Here's why sequential treatment doesn't work for co-occurring disorders:

• Mental health symptoms don't stop during addiction treatment. Untreated depression, anxiety, or PTSD actively undermine recovery.
• Substance use escalates when underlying mental health conditions aren't addressed. Relapse is almost inevitable.
• People get bounced between systems — told by mental health programs that they need to be sober first, and told by substance use programs that they need mental health clearance. This referral loop leaves people in crisis with nowhere to go.

Integrated treatment addresses both conditions simultaneously with a unified care team that understands how they interact. Research consistently shows that integrated treatment produces better outcomes: higher rates of sobriety, improved mental health stability, reduced hospitalization, and better long-term functioning.

The key elements of effective integrated treatment for co-occurring disorders include:

• A single treatment team treating both conditions together
• Trauma-informed care — recognizing how trauma underlies so many co-occurring presentations
• Medication management when appropriate (for mental health and/or medication-assisted treatment for addiction)
• Peer support from people with lived experience
• Housing stability support — because you can't heal when you don't have a safe place to sleep
• Case management that addresses the practical barriers to recovery

How Bossplayah Haven Addresses Co-Occurring Needs

Bossplayah Haven's Comprehensive Sanctuary Model was designed specifically because the existing system fails people with complex, intersecting needs — including co-occurring mental health and substance use disorders.

Traditional social services operate in silos. Mental health providers aren't always equipped to handle substance use. Addiction programs may not address domestic violence trauma. Housing programs may require sobriety. And all of them have waitlists, referral requirements, and eligibility rules that create barriers exactly when someone is most vulnerable.

Bossplayah Haven eliminates the referral loop. When you come to us, you receive:

• Trauma-informed mental health support — because trauma is almost always the root
• Substance use recovery support integrated into your overall care, not separated from it
• Domestic violence advocacy — for survivors whose co-occurring disorders developed in the context of abuse
• Housing stability — because safe shelter is the foundation that makes everything else possible
• Case management that wraps around your whole life — childcare, benefits navigation, legal support, financial literacy
• Consistent, compassionate care from people who know you — not a new intake worker every time you reach out

Our model is built on the understanding that healing happens in relationship, not in isolation. We serve single mothers, domestic violence survivors, and individuals facing homelessness — the populations most likely to be dealing with co-occurring disorders and least likely to be served well by fragmented systems.

You don't have to have it together to walk through our door. You just have to take the first step.
