Co-occurring disorders

Dual diagnosis treatment

Addiction rarely travels alone. When depression, anxiety, trauma or another condition is part of the picture, both need treatment at the same time, by the same team. That’s dual diagnosis care.

One team, both conditions

About halfof people with a substance use disorder also have a mental illness

One teamtreating both at the same time works best

Every levelof care can include dual diagnosis treatment

About half of people who have a substance use disorder will also have a mental health condition at some point, and the reverse is true too. Treating only one tends to fail, because each one keeps the other going.

Common combinations

Depression with alcohol, opioids or stimulant crashes
Anxiety and panic with alcohol, benzodiazepines or cannabis
PTSD and trauma with almost any substance, often alcohol or opioids
Bipolar disorder with alcohol or stimulants
ADHD with stimulants, cannabis or alcohol
Psychosis with stimulants or high-THC cannabis

Why integrated treatment matters

In the past, people were told to get sober before treating their mental health, or to stabilize their mental health before treating addiction. That sent them back and forth between systems. Integrated care means one plan and one team that addresses both, with psychiatry, therapy and recovery support working together.

What dual diagnosis treatment includes

A full psychiatric evaluation, not just a substance use assessment
Medication management for both conditions when it helps
Therapies with strong evidence, like CBT, DBT and trauma-focused therapy (EMDR or prolonged exposure)
Family education, so the people at home understand both conditions
A discharge plan that keeps psychiatric care going after the program

Dual diagnosis care can happen at any level, from residential treatment to weekly outpatient care. The right level depends on how stable things are right now.

See all questions

Which comes first, the addiction or the mental illness?

It can go either way, and often both grow together. Some people use substances to cope with symptoms; substance use can also trigger or worsen mental illness. Good treatment doesn’t make you sort that out first.

Will I have to stop my psychiatric medication?

Usually not. Most psychiatric medications are safe and helpful in recovery. Your care team will review everything you take and adjust only what’s needed.

How do I know a program really offers dual diagnosis care?

Ask how often you’ll see a psychiatrist or psychiatric nurse practitioner, whether therapists are licensed, and whether mental health and addiction treatment happen in the same plan. A weekly visit from an outside provider isn’t integrated care.
