Dual Diagnosis Treatment
Dual diagnosis means living with a substance use disorder and a mental health condition, such as anxiety, depression, PTSD, or bipolar disorder, at the same time. This guide covers the signs, why treating both together works better, the levels of care available, and how to find a program with a cannabis policy that works for you.
Quick answer
Dual diagnosis is treated with integrated care, meaning the same team treats both the addiction and the mental health condition at the same time, using therapy, psychiatric care, and medication when needed.
What is co-occurring disorders addiction?
Co-occurring disorders are common. Many people with a substance use disorder also have a mental health condition, and each can make the other worse.
Some people use substances to cope with anxiety, trauma, or low mood, while substance use can also trigger or deepen mental health symptoms. Treating only one side often leads to relapse.
Signs and symptoms of co-occurring disorders addiction
- Using alcohol or drugs to manage anxiety, stress, or sleep
- Mood swings, depression, or panic that get worse with use or withdrawal
- Trauma symptoms such as nightmares or flashbacks alongside substance use
- Relapsing after treatment that focused only on addiction
- Trouble keeping up with work, school, or relationships
- Feeling hopeless or having thoughts of self-harm
Dual Diagnosis withdrawal and detox
Withdrawal can intensify mental health symptoms, so anxiety, depression, or trauma responses may feel stronger in the first days. Detox programs with psychiatric support can manage both at once.
Detox is usually a short first step, often 3–10 days depending on the substance. After stabilization, ongoing dual diagnosis care focuses on therapy, psychiatric treatment, and coping skills.

Cannabis policies at co-occurring disorders rehabs
Many people use cannabis for anxiety, PTSD, sleep, or pain. Cannabis-friendly dual diagnosis programs can factor that into your care plan instead of making it a barrier to treatment.
Cannabis can worsen some conditions, such as psychosis or bipolar mania, in certain people. Be open with your psychiatric team so they can give you safe, personalized advice.
Policies vary: some programs allow medical cannabis with a card, some pause it during detox, and some require abstinence. Always confirm a program’s policy before you go.
Many facilities have not published their cannabis policy yet. Learn what each policy means in our Cannabis Policy Guide, or follow our steps on how to find a cannabis-friendly rehab.
