Hilliard, OH Dual Diagnosis Treatment: A Local Guide

What the local numbers say about co-occurring conditions

You are not imagining that this feels harder in Central Ohio than the national headlines suggest. The Alcohol, Drug and Mental Health Board of Franklin County reports that in 2023, 9.9% of Franklin County adults had a mental health impairment in the past month, compared with 7.5% of Ohioans overall ². That gap is small on paper and huge in a living room. It means the county Hilliard sits in carries a heavier month-to-month mental health load than the state average, and the people around you are more likely than most Ohioans to be quietly struggling right now.

Layer in the substance use side. The same ADAMH data estimates that roughly one in five Franklin County residents had a substance use disorder in 2023, and 26.2% of adults reported binge drinking in the past month ². Binge drinking isn't just a weekend habit label — it's often how untreated anxiety, grief, or trauma looks from the outside before anyone calls it a diagnosis.

Columbus Public Health rounds out the picture. Thirteen percent of Franklin County adults report 15 or more poor mental health days in a typical month, 7% meet criteria for an alcohol use disorder, and 8% are classified as heavy drinkers ⁵. And Ohio State's Wexner Medical Center notes that overdose deaths in the county rose 45.6% from 2019 to 2020, a jarring single-year jump that has kept local providers focused on integrated care ever since ¹.

If any of those numbers describe someone in your household, you are not an outlier here. You are one of many Hilliard neighbors trying to figure out the same thing at the same time — and that means the local infrastructure to help you exists, and it's been under real pressure to get better.

How common co-occurring conditions are across Ohio

Zoom out from Franklin County for a moment, because the statewide backdrop changes how you read the local numbers. SAMHSA's 2023 National Survey on Drug Use and Health estimates that about 1,828,000 Ohioans aged 12 and older met criteria for a past-year substance use disorder in 2022–2023. That total splits almost evenly: roughly 1,095,000 with an alcohol use disorder and 1,039,000 with a drug use disorder ⁴.

Why does that split matter to you? Because it changes what a Hilliard program's caseload looks like on any given Tuesday. If you or your loved one is struggling with alcohol, you are not walking into a room full of strangers whose experiences feel foreign. Half the state's SUD population is right there with you. If the primary struggle is opioids, stimulants, or benzodiazepines, the other half of that number reflects your reality — and it means local clinicians see this every day.

The other thing this scale tells you: when co-occurring depression, anxiety, PTSD, or bipolar disorder sits underneath either the alcohol or the drug use, that combination is the norm, not the exception. Federal guidance from NIDA frames it plainly: the overlap between substance use and other mental disorders is high enough that identifying and treating both at once should be the standard approach, not a specialty add-on ⁶.

So when you call a program near Hilliard and hear terms like "co-occurring" or "integrated," you are not being routed to a niche track. You are asking for what the data — state and local — says most people in your situation actually need.

Outpatient, IOP, PHP, residential, and detox in plain language

When you start calling programs near Hilliard, you'll hear a stack of terms that sound like acronym soup: ASAM, IOP, PHP, LOC 3. Here's the plain-language version, because you deserve to know what you're being sold before you commit to it.

Ohio Medicaid requires that substance use disorder treatment services be defined and delivered according to ASAM criteria — the American Society of Addiction Medicine's framework for matching a person to the right intensity of care. That standard applies to admission, to continued stay, and to discharge, and it explicitly includes co-occurring conditions ³. Translation: a program can't just say "you look like a residential case, come on in." There's a structured assessment behind the recommendation, and you can ask to see how you scored.

The levels, from lightest to most intensive:

Outpatient (Level 1). Typically one to a few hours a week. Individual therapy, group, and psychiatric medication management. You keep working, keep sleeping at home, keep parenting.

Intensive Outpatient (IOP) and Partial Hospitalization (PHP) (Level 2). IOP usually runs about 9–19 hours a week across three to five days. PHP is more like a day program — often 20+ hours a week, five days a week — where you go home at night. Both are common landing spots for co-occurring care because they combine real structure with real life.

Residential/Inpatient (Level 3). Twenty-four-hour treatment. Ohio's rule specifies that Level 3 services are "co-occurring capable, co-occurring enhanced, and complexity capable," delivered by addiction, mental health, and general medical staff together ³.

Medical detox (Level 3.7/4). Short-term, medically supervised withdrawal management for alcohol, opioids, or benzodiazepines when stopping on your own would be dangerous. It's a starting point, not a whole treatment plan.

You are allowed to step up or down between these levels as your needs change. That is how the framework is designed to work.

Co-occurring capable vs co-occurring enhanced: how to tell them apart on a phone call

Two programs can both say they "treat dual diagnosis" and still deliver very different care. Ohio's rule uses specific language here: Level 3 residential services are described as co-occurring capable, co-occurring enhanced, and complexity capable ³. Those aren't marketing labels. They point to how deeply mental health is woven into the program.

Co-occurring capable programs can safely treat people whose mental health condition is stable — say, depression managed on a steady medication, or anxiety that flares but isn't disabling. The primary focus is substance use, with mental health support alongside.

Co-occurring enhanced programs are built for people whose psychiatric symptoms are more acute or unstable — active PTSD symptoms, bipolar disorder in a mixed state, severe depression with suicidal thinking. Psychiatric staffing is deeper, and the mental health work runs on equal footing with the addiction work.

On the phone, three questions cut through the marketing:

1. "Is your program co-occurring capable or co-occurring enhanced?" If they can't answer, that's your answer.

2. "Do the same clinicians treat both conditions, or do you refer out for mental health?" Integrated care means one team, one plan ¹³.

3. "How is my ASAM assessment used to decide my level of care and when I step down?" ³

You are not being difficult by asking. You are doing exactly what the framework expects of you.

Where integrated care clearly helps

Here is the honest version of the research, because you deserve that too. Integrated care is not magic, but there are specific places where the evidence lands clearly on its side, and those are worth knowing before you say yes to a program.

Start with psychiatric symptoms. A 2023 systematic review comparing integrated and non-integrated treatment in dual diagnosis populations found that integrated treatment produced a significant advantage in improving psychiatric symptomatology — meaning the depression, anxiety, PTSD, or bipolar symptoms measured on standardized scales moved more when both conditions were treated on one team ¹². If the mental health side is what wakes you up at night, this is the finding that matters most.

Then there is engagement and long-term outcomes. Drake and colleagues' review of 36 studies found that when comprehensive integrated outpatient treatment ran for 18 months or longer, substance use dropped significantly, remission rates went up, and hospital use went down ^{7, 9}. The length matters. Short bursts of care do not seem to move the needle the same way sustained, coordinated treatment does.

A 2023 review of co-located outpatient care — mental health and substance use clinicians working in the same setting — reported provisional evidence of reduced substance use, lower symptom severity, better quality of life, fewer emergency department visits, and reduced health system costs ¹⁰. And a 2026 umbrella review of 28 systematic reviews concluded that coordinated integrated treatment is usually better than treating one condition alone and often better than parallel uncoordinated services ¹¹. Better than nothing. Better than fragmented. That is a real bar.

Where the evidence is more mixed

Now the harder part. If a program tells you integrated care will fix everything faster and better than any other option, they are getting ahead of the research.

That same 2023 review that found a psychiatric-symptom advantage also found no significant difference between integrated and non-integrated care on two outcomes that matter a lot to you: substance misuse itself and treatment retention ¹². Put plainly, whether people kept using and whether they stuck with treatment did not clearly favor the integrated model over well-structured non-integrated care in that analysis.

Drake and colleagues were similarly candid. While comprehensive integrated outpatient programs looked encouraging for engagement and remission, their results for hospital use and psychiatric symptoms across studies were less consistent, and they called for more controlled research ⁹. The SAMHSA evidence kit, which supports integrated treatment overall, also acknowledges gaps in long-term and high-quality randomized trials ¹³.

So what do you do with that? A few things. Ask a program how long its integrated track actually runs, because 18 months of coordinated outpatient care looks different in the data than a 30-day residential stay followed by a warm handoff ⁷. Ask what they measure and how often. And give yourself permission to judge a program on the specifics — same team, coordinated plan, real psychiatric staffing — rather than the label alone.
