Can You Treat My Teen’s Mental Health and Addiction at the Same Time?
Yes. At Guardian Recovery – Montville Adolescent Center, treating both conditions simultaneously isn’t just possible — it’s the foundation of how we approach care.
When a teen struggles with both a mental health disorder and a substance use disorder, the two conditions are almost always connected. Anxiety or depression can lead a teen to self-medicate with substances. Substance use can worsen underlying mental health symptoms. Treating only one without the other is rarely effective — and research shows that teens who receive treatment for only one condition are significantly more likely to relapse and return to treatment within the first year.
This combination is called a dual diagnosis — also referred to as co-occurring disorders or comorbidity. According to NIDA, more than 60% of adolescents in substance use treatment also meet criteria for a mental health disorder, making adolescent dual diagnosis far more common than many families realize. SAMHSA further notes that people with co-occurring disorders require integrated treatment to achieve lasting recovery. If your teen has been diagnosed with both — or if you suspect both are present — there is a treatment approach designed specifically for this.
Teen Co-Occurring Disorder Treatment in Morris County, New Jersey
Guardian Recovery – Montville Adolescent Center is a Joint Commission-accredited residential program serving teens ages 13–17 in Towaco, Morris County, NJ. As part of the Guardian Recovery network — a nationwide behavioral health organization with more than 20 years of experience — Montville offers one of the few dedicated teen dual diagnosis residential programs in Northern New Jersey.
We serve families throughout Morris County and the surrounding region, including Montville, Morristown, Parsippany, Boonton, Mountain Lakes, Lincoln Park, Wayne, Cedar Knolls, and communities across Northern NJ. The NJ Division of Mental Health and Addiction Services (DMHAS) recognizes that integrated treatment for co-occurring disorders is the most effective approach — which is the model we practice at Montville Adolescent every day.
What Is a Dual Diagnosis — and What Are Co-Occurring Disorders?
A dual diagnosis (also called a co-occurring disorder) means your teen has both a mental health condition and a substance use disorder at the same time. The terms dual diagnosis, co-occurring disorder, and comorbidity all describe the same clinical picture.
Common combinations in adolescents include:
- Anxiety + alcohol or marijuana use
- Depression + substance use
- ADHD + stimulant or alcohol misuse
- Trauma (PTSD) + substance use
- Bipolar disorder + substance use
- OCD + substance use
These conditions frequently overlap and reinforce each other. A teen using substances to manage anxiety isn’t simply making bad choices — they’re attempting to cope with a real mental health need. Without treating that underlying need, substance use treatment alone rarely leads to lasting recovery.
Why Does Treating Both at the Same Time Matter?
This is one of the most important questions families ask — and one most treatment centers don’t answer directly.
When a teen receives treatment for only one condition — say, substance use treatment without addressing underlying depression — the untreated mental health condition continues to drive the behavior. The teen may complete treatment but return to substance use as a way of managing their mental health symptoms. This is one of the primary drivers of early relapse in adolescent treatment.
Conversely, treating mental health in isolation while ignoring substance use misses the self-medication component entirely. Integrated, simultaneous treatment — the model we use at Montville Adolescent— addresses both the symptom and the underlying cause at the same time, giving your teen the best chance at lasting recovery.
How Does Guardian Recovery – Montville Adolescent Center Treat Both at the Same Time?
Our dual diagnosis program is built around integrated, simultaneous treatment — meaning your teen’s mental health condition and substance use disorder are assessed and treated together, by the same clinical team, from day one.
Here’s what that looks like in practice:
- Comprehensive assessment on arrival. Every teen undergoes a full psychiatric evaluation alongside a substance use assessment, so our team understands the full picture before designing a treatment plan.
- Integrated treatment planning. Rather than treating mental health and substance use separately, our team builds a single, unified plan that addresses both simultaneously.
- Evidence-based therapies. Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), trauma-informed care, and motivational interviewing — all proven effective for co-occurring disorders in adolescents.
- Medication management when appropriate. For teens whose mental health condition may benefit from psychiatric medication, our on-site medical team — led by Dr. Tamer Wassef, board-certified in psychiatry and addiction medicine — can evaluate, prescribe, and monitor throughout their stay.
- Family involvement. Co-occurring disorders affect the entire family. We include parents and caregivers through family therapy sessions and regular communication with our clinical team.
- Academic support. Because Montville Adolescent Center serves school-age teens, we coordinate with your teen’s school to support continued academic progress during treatment. Our team works with school counselors to ensure your teen doesn’t fall behind while they’re getting the help they need.
What If We’re Not Sure Whether It’s One or Both?
You don’t need a formal dual diagnosis before calling us. Many families come to us unsure whether their teen’s mental health symptoms are driving the substance use, or vice versa. Our intake assessment is designed to figure that out.
Our team will complete a thorough evaluation during the admissions process and share findings with you in plain language before treatment begins. Reach out to our admissions team anytime — we’re here to help.
Will My Teen Be in Groups with Other Teens Who Have Different Issues?
Every teen at Guardian Recovery – Montville Adolescent Center shares more in common than parents might expect. Dr. Frank Mattiace, our Executive Director, explains it this way: virtually every teen in our program has some form of anxiety or depression — these are foundational elements across all participants, regardless of whether their primary presenting issue is a mental health condition or substance use.
There is not a separate track for mental health and substance use disorder. Rather than dividing teens by diagnosis, our integrated program recognizes that co-occurring conditions are the norm — not the exception — in teen dual diagnosis treatment. Group sessions are small, carefully supervised by licensed clinical staff, and structured to create a safe, therapeutic environment where teens connect with peers who genuinely understand what they’re going through.
Your teen will also never be in treatment alongside adults — Montville serves adolescents only, ages 13 to 17.
If you have specific questions about how your teen’s program will be structured, our admissions team can walk you through exactly what to expect. Contact us here.
What Happens After Residential Treatment for Co-Occurring Disorders?
Residential treatment is the beginning of your teen’s recovery journey — not the end. For teens with co-occurring disorders, continued care after residential treatment is especially important to maintain progress on both the mental health and substance use fronts.
As part of the Guardian Recovery network, Montville Adolescent helps families transition to the appropriate next level of care after residential, including:
- Partial Hospitalization Program (PHP) — intensive daytime treatment, 5–6 hours per day, allowing your teen to return home in the evenings
- Intensive Outpatient Program (IOP) — structured therapy 3+ days per week, compatible with a return to school
- Alumni Program — ongoing community and support after formal treatment ends
Our clinical team will recommend the appropriate step-down level of care based on your teen’s progress and continued clinical needs. The goal is a smooth, supported transition back to daily life.
Does Insurance Cover Dual Diagnosis Treatment in New Jersey?
In most cases, yes. The Mental Health Parity and Addiction Equity Act (MHPAEA) and the Affordable Care Act (ACA) require insurance plans to cover mental health and substance use treatment at the same level as other medical care. New Jersey also has its own state parity law that provides additional protections for NJ residents.
Our admissions team will verify your insurance benefits before your teen is admitted — at no cost to you. Verify your insurance here and we’ll explain exactly what’s covered and what your out-of-pocket costs may be. For more detail, see our full insurance FAQ page.
