Treatment

Dual diagnosis treatment in Orange County

Many people with a substance use problem also live with depression, anxiety, PTSD or another mental health condition. Treating both at the same time works better than treating one at a time.

What to ask a program

  • Is there a psychiatrist or psychiatric nurse practitioner on the team?
  • Can you continue or adjust my mental health medication?
  • Which therapies do you use, such as CBT, DBT or EMDR?
  • How do you handle a mental health crisis?

How common it is

National surveys consistently find that a large share of adults with a substance use disorder also have a mental illness in the same year. Each condition can make the other worse: drinking to quiet anxiety, using stimulants to lift depression, or substances triggering panic or psychosis. Treating only one often leads to relapse in the other.

What integrated care looks like

  • A full psychiatric assessment, not just a substance use history
  • A prescriber who can manage mental health medication safely alongside recovery
  • Therapy that addresses both, such as CBT, DBT or trauma-focused work
  • A discharge plan that includes ongoing mental health care, not only addiction support

If mental health is the bigger crisis right now

Thoughts of suicide, hearing voices, or not sleeping for days need urgent care. Call or text 988, call OCLinks at (855) 625-4657, or go to the nearest emergency room.

Medication and mental health

Some people worry treatment will take away mental health medications that help them. A good dual diagnosis program reviews each medication with a prescriber and keeps what is safe and effective. Bring a full list, including doses, and the name of your current prescriber.

Does insurance cover dual diagnosis treatment?

Usually, yes. Mental health and substance use treatment are both covered benefits under most plans and Medi-Cal. Ask the program to verify both.
