Programs / Dual Diagnosis
Dual Diagnosis Treatment.
Dual diagnosis treatment for when a mental health disorder and a substance use disorder occur together. Our PHP and IOP programs deliver integrated treatment — psychiatry, therapy, and recovery support in one plan, not two siloed tracks.

What dual diagnosis actually means
Two diagnoses, one treatment plan.
The question isn’t whether you need support. It’s whether the support you have matches the weight you’re carrying.
Dual diagnosis — also called co-occurring disorders — means a mental health condition and a substance use disorder are active at the same time. They rarely stay in neat lanes. Depression dulls the pain until alcohol makes it worse. Anxiety drives the pills. Post-traumatic stress disorder sits underneath both. Each condition can worsen the symptoms of the other.
Treating them separately rarely works. Addiction treatment that ignores mental illness misses the depression that drives relapse. Mental health care that ignores substance abuse leaves medication unstable and progress fragile. At High Tide, dual diagnosis treatment means one clinical team holds the full picture — psychiatry, individual therapy, group work, and recovery skills inside the same PHP or IOP day.
We’re a primary mental health program with integrated substance use / substance abuse care — not a detox facility or 12-step-only model. If you need medically supervised detox or residential stabilization first, we’ll help you get there and plan outpatient step-down when you’re ready. Symptoms of mental health conditions and substance use are assessed together so neither gets minimized.
Why they occur together
Shared roots. Reinforcing loops.
People often ask which disorder comes first. Sometimes mental health symptoms lead to self-medication with alcohol or drugs. Sometimes substance use changes mood, sleep, and brain reward pathways enough to spark or intensify a mental health disorder. Often both pathways are running at once — which is why integrated treatment for both conditions matters more than debating sequence.
01
Self-medication
Substances can temporarily relieve anxiety, low mood, or trauma symptoms — then worsen the underlying mental health condition over time and raise the risk of relapse when use stops without support.
02
Shared vulnerability
Genetics, trauma, and chronic stress can raise risk for both mental disorders and substance use disorder. The same history often shows up in both charts, even when the labels arrived years apart.
03
Overlapping presentation
Impulsivity, sleep collapse, and mood swings can look like addiction, mental illness, or both. Comprehensive screening in week one sorts the picture so the treatment plan addresses conditions simultaneously.
Who it's for
For when mental health and substance use are tangled together.
Dual diagnosis treatment at High Tide is for people whose drinking, drug use, or other substance patterns are intertwined with depression, anxiety, trauma, or mood instability — and who need structured outpatient care that treats both conditions together.
This level of care fits when
- You’ve tried addiction treatment and mental health care in separate programs — and neither stuck.
- Substance use is how you cope with mental health symptoms, and stopping without support for the underlying condition feels impossible.
- You’re stepping down from residential treatment or detox and need integrated outpatient structure.
- Medication for a mental health disorder is complicated by active substance use — and you need a psychiatrist who understands both.
- You want recovery support woven into therapy, not bolted on as an afterthought.
A different path may fit better when
- You need medical detox or 24/7 supervision for withdrawal — we’ll refer you to trusted partners and coordinate your step-down.
- Substance use is resolved and mental health is the only active concern — our standard PHP or IOP may be a better fit.
- You’re looking for a primary addiction-only program without mental health integration.
- You’re in immediate crisis — inpatient stabilization comes first.
What we treat here
What we treat together — not in silos.
Most clients arrive with overlapping mental health conditions and a substance use disorder. Our clinical team maps the full picture in your first days and builds one individualized treatment plan — not a mental health track and a separate addiction track.
01
Mental health drivers
The mental disorders that often sit underneath substance use — treated directly, not dismissed as collateral damage.
- Major depression
- Anxiety & panic
- PTSD & complex trauma
- Bipolar disorder
02
Substance use patterns
Alcohol use disorder, prescription misuse, and other substance use treated as coping mechanisms to understand and replace — not moral failures to punish.
- Alcohol use disorder
- Prescription misuse
- Cannabis dependence
- Polysubstance use
03
Behavioral overlap
Patterns that show up across both domains — impulsivity, emotional flooding, self-harm, relationship chaos — and shape how treatment engages.
- Emotion dysregulation
- Self-harm behaviors
- Impulsive decision-making
- Relationship instability
04
Life context
The stressors that keep both conditions active — treated as clinical data, not background noise.
- Grief & loss
- Career collapse
- Family conflict
- Legal & financial strain
You don’t need a formal dual diagnosis label to call. If mental health and substance use feel connected in your life, that’s enough to start a conversation. Our assessment sorts out the details.
See everything we treatWhat to expect
Programming hours and weekly groups.
Here is how PHP and IOP are structured — plus the group types offered every week. Dual diagnosis treatment is woven through the clinical day, not parked in a single specialty group.
Our groups aim for a holistic, clinically excellent, and human approach to healing. Programs address the whole self — brain, mind, and body — with a wide range of perspectives and ways to engage in treatment. Psychiatry monitors both mental health medications and recovery stability; individual therapy addresses triggers, cravings, and underlying trauma in the same sessions.
PHP
9 AM – 4 PM
Full-day programming five days a week — individual therapy, group work, psychiatry, and holistic practices in one integrated day.
IOP
Morning & afternoon tracks
Part-day sessions several days per week. Morning and afternoon tracks are offered so you can keep work, school, or family routines while staying anchored in treatment.
Group
Dialectical behavior therapy (DBT focus)
Dialectical behavior therapy skills for emotion regulation, distress tolerance, and interpersonal effectiveness.
Group
Therapeutic Process Groups
Small-group therapy where emotional triggers, relationship patterns, and recovery challenges surface and get worked in real time.
Group
Relationships / Family Based Groups (IFS/ACT Focus)
Internal Family Systems and Acceptance and Commitment Therapy lenses on attachment, family dynamics, and values-aligned connection — including family therapy themes when clinically useful.
Group
Physical Movement Groups
Body-based sessions that support regulation, energy, and the physical side of recovery — part of the clinical week, not optional fluff.
Group
Recovery (SUD & MH track focus)
Integrated recovery groups with substance use and mental health tracks — cravings, relapse prevention, and the mental health drivers underneath both.
Group
Somatic Healing Groups
Breathwork, sound bowls, and mindfulness exploration for nervous-system regulation and trauma-informed body awareness.
Group
Art-Based Expression / Music-Based Process Groups
Creative process groups for clients who access emotion and insight more readily through art and music than talk alone.
Group
Cognitive behavioral therapy (CBT focus)
Cognitive behavioral therapy for thought patterns, behaviors, and the loops that keep depression, anxiety, and related symptoms going.
Group
Aftercare Planning Groups
Discharge and aftercare planning so outpatient therapy, medication, recovery support, and home structure are mapped before you leave.
Group
Adventure
Experiential outdoor and adventure-based groups that practice regulation, trust, and peer connection outside the therapy room.
What's included
Evidence-based therapies for both conditions.
Your integrated treatment plan draws on evidence-based therapies chosen for how they work together — not how they look on a checklist.
01
Integrated psychiatry
Medical professionals who prescribe with both mental health and substance use history in view — medication decisions made carefully, monitored closely when therapy and medication need to move together.
02
Trauma-informed therapy
EMDR, cognitive behavioral therapy, and somatic work for the trauma — including post-traumatic stress disorder — that often drives both conditions, paced to your capacity.
03
Dialectical behavior therapy
Dialectical behavior therapy for emotion regulation, distress tolerance, and interpersonal skills — the toolkit for staying steady when feelings get loud and substance use has been the old exit.
04
Relapse prevention
Structured planning for triggers, cravings, and high-risk situations — built into daily groups and individual sessions so risk of relapse is named early, not after discharge.
05
Family education
Sessions that help families understand dual diagnosis and co-occurring disorders — because support at home changes quality of life and follow-through.
06
Holistic regulation
Breathwork, movement, and mindfulness by the ocean — body-based skills that support both mental health symptoms and recovery.
What changes
What integrated treatment actually changes.
Dual diagnosis recovery isn’t linear. Our job is to stabilize both conditions enough that you leave with skills, a medication plan if needed, and an aftercare map for long-term recovery that doesn’t pretend one diagnosis disappeared.
1 plan
One unified treatment plan — not parallel tracks that never talk to each other.
1–2×
Weekly psychiatry and therapy touchpoints in PHP, adjusted as both conditions evolve.
Planned
Discharge planning with outpatient therapy, medication, and recovery support mapped.
Week 1
Full biopsychosocial assessment including substance use history — screening both conditions from day one.
Not sure PHP is the right level?
PHP and IOP, side by side.
Integrated dual diagnosis care needs enough clinical hours to address mental health and substance use together — PHP when either domain is acute; IOP when you’re stable enough for structured outpatient recovery. Here’s the comparison.

How to start
From first call to first day — usually within a week.
Admissions is one phone call, not a paperwork gauntlet. Here’s the whole process.
01
Call or verify online
A confidential conversation with our admissions team — what’s going on, what you’re looking for, and whether dual diagnosis treatment is the right fit. We verify your insurance the same day, usually while you’re still on the phone.
02
Clinical assessment
A licensed clinician conducts a full biopsychosocial assessment — history, symptoms, safety, and level-of-care fit. If PHP, IOP, or outpatient is not the right match, we’ll say so and help you get there instead.
03
Start within days
Clients often begin within a few days of assessment when clinical fit and insurance align. Your first days include psychiatric evaluation, meeting your primary therapist, and building the treatment plan everything else draws from.
Most PPO plans cover this program. Verification is free, confidential, and usually same-day.
Common questions
Answers before you have to ask.
Can't find your question? Call us — a real person answers, and there's never pressure to commit.
Will insurance cover dual diagnosis treatment?
Most PPO plans cover PHP and IOP for mental health, and California parity law requires insurers to cover mental health care at the same level as physical health care. We verify your exact benefits before you commit — free, confidential, and usually same-day. Start at /insurance or read /mental-health-guides/does-insurance-cover-php-iop.
Can I keep working during treatment?
It depends on the level of care. PHP runs 9 AM to 4 PM, five days a week — most clients pause or reduce work. IOP is part-day sessions, several days a week, and is built to run alongside part-time work, school, or caregiving. Compare both in /mental-health-guides/php-vs-iop.
How long will treatment last?
Length follows clinical need, not a fixed package. Your team reviews progress weekly, and you step down when symptoms and functioning support less intensity. Many clients finish with outpatient mental health treatment.
What if I’m coming from out of town?
Many clients travel to Laguna Beach for treatment. We can help arrange optional supportive housing within a few minutes of the facility. Evenings and weekends are yours — housing is optional, not required for PHP or IOP. Local families often start on /mental-health-treatment-orange-county.
Is this the same as being hospitalized?
No. There is no overnight stay at the facility, no locked unit, and no hospital setting. PHP and IOP deliver structured clinical intensity inside a calm outpatient facility you leave the same day. See /mental-health-guides/what-is-php-mental-health and /mental-health-guides/what-is-iop-mental-health.
What happens after I finish?
Nobody leaves without a plan. Before discharge, your team builds a written aftercare plan: step-down to IOP if appropriate, referrals to outpatient mental health treatment, psychiatry when needed, and follow-up check-ins from our team in the weeks after you leave.
What is dual diagnosis?
Dual diagnosis means a mental health disorder and a substance use disorder occur together in the same person — also called co-occurring disorders. Dual diagnosis treatment addresses both conditions at the same time instead of sending you to separate programs that never coordinate. Orange County families can also read /dual-diagnosis-treatment-orange-county.
Does one cause the other?
Not always in one direction. Mental health symptoms can lead someone to use alcohol or drugs to cope. Substance use can also intensify or help spark mental health symptoms. Shared genetic and trauma risk can raise vulnerability to both. Clinically, we treat the loop in front of us rather than waiting to prove which label came first.
What is the best treatment for dual diagnosis?
The strongest evidence supports integrated treatment — one team, one plan, treating mental health and substance use disorder together. At High Tide that happens in PHP or IOP with psychiatry, therapy, and recovery work in the same week. Siloed addiction treatment or mental health care alone often leaves the untreated side pulling progress backward.
Do I need to be sober to start?
You need to be medically stable for outpatient care — not necessarily fully sober. If active withdrawal or medical risk is present, we’ll help you access detox first. Many clients arrive early in recovery; the program meets you where you are.
Is this a 12-step program?
No. We’re a clinical mental health program that integrates recovery principles. Some clients find peer support groups helpful alongside treatment; others don’t. We build your aftercare plan around what actually works for you.
How do you choose PHP vs IOP for dual diagnosis?
PHP is the fuller clinical day when symptoms, substance use, or instability need more structure. IOP keeps the same integrated model in part-day tracks when you can hold more of life outside treatment. Assessment in week one recommends the level — and we step you between them as both conditions stabilize. Compare: /mental-health-guides/php-vs-iop.
