Dual diagnosis treatment addresses substance use disorder and mental health conditions at the same time, within the same program. In Maine, where opioid use disorder is the leading driver of overdose deaths and depression, anxiety, and PTSD run alongside it in most cases, integrated treatment is the clinical standard. If you or someone you love has been through programs that treated the addiction but left the mental health piece untouched, or that addressed anxiety but never confronted the substance use, this is what was missing: a program that treats both, with the same team, at the same time.
What Is Dual Diagnosis? A Plain-Language Answer
Dual diagnosis means a person has both a substance use disorder and a mental health condition occurring at the same time. Common pairings include opioid use disorder with depression, alcohol use disorder with PTSD, and stimulant use with anxiety. The clinical term is “co-occurring disorders,” and the conditions are more common together than apart. According to the Substance Abuse and Mental Health Services Administration’s National Survey on Drug Use and Health, roughly half of people with a substance use disorder also meet criteria for a mental health condition.
This is not a rare combination. It is especially common among justice-involved individuals, where trauma, poverty, unstable housing, and systemic barriers compound both conditions. In Maine, the overlap between substance use and mental health diagnoses is the norm in treatment settings, not the exception.
Why Treating One Without the Other Doesn’t Work
When a program treats addiction without addressing the mental health condition underneath it, the person may achieve temporary sobriety. But the depression that made substances feel necessary is still there. The PTSD that substances were numbing is still there. And when those symptoms resurface, the pull toward self-medication is powerful enough to override everything the person learned in treatment.
The reverse is also true. Treating anxiety or depression while someone is actively using substances is like adjusting a thermostat in a building with no walls. The medication may help, the therapy may land, but the active substance use destabilizes the neurochemistry that treatment is trying to regulate.
Sequential treatment, where a person completes a substance use program and then is referred to a separate provider for mental health, creates gaps. Gaps in care become gaps in stability. Integrated dual diagnosis treatment eliminates those gaps by placing substance use treatment and mental health counseling under the same clinical roof, with providers who communicate in real time about the whole person.
How ENSO Treats Co-Occurring Disorders
ENSO Recovery provides integrated treatment for substance use disorder and mental health conditions through a model built around medication-assisted treatment (MAT), individual therapy, intensive outpatient programming (IOP), and case management. The clinical team does not treat addiction first and mental health second. Both are addressed from the start, by the same team, within the same treatment plan.
The process begins with a call to ENSO’s intake line. The goal is to get each client in front of a medical provider for a full clinical evaluation within 24 hours. From there, an individualized treatment plan is built around the client’s specific diagnoses, circumstances, and goals. At minimum, Phase 1 includes weekly individual therapy and weekly prescriber visits. Clients who need more intensive support enter IOP, which uses group therapy and life skills programming to address both substance use and co-occurring mental health conditions simultaneously.
Case management connects clients to housing, employment, and community resources, because stability outside the treatment room directly affects outcomes inside it. Telehealth is available for weekly therapy sessions at both locations, removing a transportation barrier that keeps many Maine residents from accessing consistent care.

The Role of MAT in Dual Diagnosis Recovery
Medication-assisted treatment is the pharmacological anchor of ENSO’s model, and it plays a specific role for clients with co-occurring disorders. MAT stabilizes the neurochemistry disrupted by substance use, which creates the conditions for mental health treatment to actually work. A client whose brain is in constant withdrawal or craving cannot engage meaningfully in therapy for depression or PTSD. Medication changes that equation.
ENSO offers buprenorphine (Suboxone, Subutex), Sublocade (a monthly injectable), Brixadi (an extended-release injectable), and Vivitrol. Roughly 40% of ENSO’s clients are on long-acting injectable medications, a rate that leads the state. The advantage of injectables for dual diagnosis clients is practical: Sublocade is a monthly injection. The client shows up, receives the medication, and does not have to make daily dosing decisions. For someone managing depression, anxiety, or PTSD alongside a substance use disorder, removing one daily decision point reduces cognitive burden and improves medication adherence.
MAT is not a workaround. It is evidence-based medicine. The National Institute on Drug Abuse identifies MAT as the gold standard for opioid use disorder treatment, and the federal and state governments are actively expanding access to injectable formulations because the data supports their effectiveness. ENSO does not require clients to taper off medication as a condition of treatment or housing. All five recovery residences accept clients on MAT.
Dual Diagnosis Treatment in Maine: What ENSO Offers in Augusta and Sanford
ENSO operates two outpatient centers, each serving a distinct population and geography.
The Augusta location at 90 Western Avenue draws from Kennebec County and northern Maine. It runs a more structured therapeutic community with a heavier clinical hand. Recovery residences in Augusta include a 13-bed women’s house, a 22-bed men’s house, and a two-bedroom Phase 4 apartment for clients approaching independent living. All residences are MARR-certified (Maine Association of Recovery Residences) at Level II and Level III.
The Sanford location at 14 Winter Street serves York County and southern Maine, extending toward Portland. It is oriented more toward individuals earlier in their treatment journey or entering care for the first time. Sanford also operates gender-specific recovery residences for clients who need stable housing as part of their treatment plan.
ENSO was built around the conviction that the 72 hours after release from incarceration are the most dangerous window for relapse. The organization was the first substance use treatment program to bring MAT inside Maine county jails, operating IOP and clinical services inside Two Bridges Regional Jail in Wiscasset. Clients who begin treatment while incarcerated transition directly into ENSO’s sober living and outpatient programs upon release, with no gap in care.
All services are covered by MaineCare/Medicaid. The financial barrier is not lowered; it is removed.
Frequently Asked Questions About Co-Occurring Disorder Treatment
What Is Dual Diagnosis Treatment and How Is It Different From Standard Rehab?
Dual diagnosis treatment addresses both a substance use disorder and a mental health condition within the same program, by the same clinical team. Standard rehab often focuses on substance use alone, leaving mental health conditions untreated. Integrated treatment produces better outcomes because the two conditions directly influence each other.
Can ENSO Treat My Mental Health Condition and My Addiction at the Same Time?
Yes. ENSO’s model is built around integrated care. Individual therapy, group programming, medication management, and case management all address substance use and mental health simultaneously from the first assessment forward.
Does MaineCare or Medicaid Cover Dual Diagnosis Treatment in Maine?
Yes. ENSO accepts MaineCare/Medicaid for all services, including MAT, IOP, individual counseling, and case management. There is no cost barrier to accessing treatment.
What Mental Health Conditions Are Most Commonly Treated Alongside Opioid Use Disorder?
Depression, anxiety, PTSD, and trauma-related conditions are the most common co-occurring diagnoses among clients with opioid use disorder. Bipolar disorder and other mood disorders also occur frequently.
Does ENSO Require Clients to Be Off Medication Before Starting Treatment?
No. ENSO does not require clients to taper or discontinue medication-assisted treatment at any point. All recovery residences accept clients on MAT, and the clinical model treats medication as a clinical asset, not a temporary measure.
How Does Medication-Assisted Treatment Work for Someone With a Co-Occurring Mental Health Condition?
MAT stabilizes the neurochemistry disrupted by substance use, which creates the conditions for mental health treatment (therapy, counseling, psychiatric medication if needed) to work effectively. Injectable options like Sublocade and Brixadi reduce daily cognitive burden, which is particularly beneficial for clients managing mental health symptoms alongside recovery.
What Happens During the First 24 Hours After I Call ENSO?
ENSO’s goal is to get every new client in front of a medical provider for a full clinical evaluation within 24 hours of the initial call. The evaluation determines the appropriate level of care and produces an individualized treatment plan addressing both substance use and mental health.
Can Someone With a Criminal Record Get Dual Diagnosis Treatment in Maine?
Yes. ENSO was founded on the model of providing treatment to justice-involved individuals. The program operates clinical services inside Two Bridges Regional Jail and provides a seamless transition from incarceration to community-based treatment. A criminal record is not a barrier to accessing care at ENSO.
