Dual Diagnosis Treatment in Los Angeles

Treating co-occurring mental health and substance use disorders together — because they can't be separated

Medically reviewed by Dr. Eric Chaghouri, MD — Medical Director, Golden State Rehab Updated March 2026
What Is Dual Diagnosis?

Two Conditions, One Integrated Treatment Plan

Dual diagnosis — also called co-occurring disorders — refers to the simultaneous presence of a mental health condition and a substance use disorder. The two are deeply intertwined: people use substances to cope with mental health symptoms, and substance use worsens mental health over time, creating a cycle that neither condition alone can explain or break.

Treating only one condition while leaving the other unaddressed dramatically increases the risk of relapse and deterioration. Our integrated dual diagnosis program addresses both simultaneously — through the same clinical team, within the same treatment episode.

How We Treat It

Our Dual Diagnosis Approach

Comprehensive Assessment

A thorough psychiatric and substance use evaluation identifies all co-occurring conditions, their severity, and how they interact — creating a complete clinical picture that informs every aspect of your individualized treatment plan.

Integrated Treatment Planning

A single, coordinated treatment plan addresses both your mental health and substance use — eliminating the confusion and gaps that occur when two separate systems provide disconnected care.

Psychiatric Medication Management

Our psychiatrists carefully manage medications for both mental health symptoms and substance use disorder, monitoring for interactions and adjusting treatment as your brain chemistry stabilizes in recovery.

Dual Diagnosis CBT

Specialized cognitive-behavioral therapy adapted for co-occurring disorders addresses the thought patterns, avoidance strategies, and self-medication behaviors that maintain both conditions simultaneously.

Dual Diagnosis Group Therapy

Group sessions with peers who understand the specific experience of living with both a mental health condition and addiction — reducing isolation and shame while building community and accountability.

Family Education & Therapy

Families are profoundly affected by dual diagnosis — and they play a crucial role in recovery. We offer family therapy and psychoeducation to help loved ones understand the conditions and how to provide effective support.

Common Combinations

Co-Occurring Conditions We Treat

Dual diagnosis encompasses a wide range of condition combinations. Some of the most common co-occurring patterns we treat:

  • Depression + alcohol use disorder
  • Anxiety disorders + benzodiazepine or alcohol dependence
  • PTSD + opioid use disorder
  • Bipolar disorder + substance use
  • ADHD + stimulant misuse
  • Complex trauma + multiple substance use disorders
  • Personality disorders + addiction

If you've struggled with both mental health and substances — and feel like neither problem fully explains your experience — dual diagnosis treatment may be the key that's been missing.

Dual Diagnosis Treatment: Common Questions

It means living with a mental health condition and a substance use disorder at the same time — like depression plus alcohol use, or PTSD plus opioids. The two feed each other, which is why they need to be treated together, by one team, in one plan.

Because the untreated condition tends to pull the other one back. Substance use often starts as a way to cope with mental health symptoms, and it makes those symptoms worse over time. Integrated treatment breaks the whole cycle instead of half of it.

No. We never notify employers. Your records are protected by HIPAA, and substance use treatment records get extra federal protection under 42 CFR Part 2. Evening IOP and telehealth options make it possible to get help while you keep working.

In most cases, yes. Under federal parity law and California's SB 855, health plans must cover medically necessary mental health and addiction treatment. Verification is free and confidential — we'll check your exact benefits before you commit to anything.
