A co-occurring disorder describes a mental health condition and a substance use disorder appearing in the same person at the same time. But what if the bigger issue is how the two connect? Since the two overlap so often, treating them separately usually leaves one condition untreated.
That overlap also shapes the kind of support a person needs. Mental health and co-occurring substance use treatment brings both concerns into one plan, exactly as the outpatient levels of care at Cholla Behavioral Health do.
From here, you will see how the two connect, which conditions overlap most, the signs worth noticing, and what integrated care involves.
How Are Mental Health and Substance Use Connected?
Mental health and substance use influence each other in both directions. Anxiety, low mood, or unresolved stress often pushes someone toward substance use that offers quick (temporary) relief.
The influence runs the other way too, because substance use disturbs sleep, mood, and thinking until emotional symptoms grow heavier.
They can also share the same risk factors, since genetics, environment, and trauma raise the odds of both.
What Mental Health Concerns Can Co-Occur With Substance Use?
Anxiety, depression, and trauma-related conditions co-occur with substance use more than any other group, though several further diagnoses appear regularly. Each interacts with substance use differently, which changes what treatment must address. With those differences in mind, here are the 4 categories clinicians see most often.
1. Anxiety and substance use
Anxiety and substance use connect through relief, since alcohol or sedatives calm the body quickly. That calm fades fast, though, and repeated use creates 3 common patterns.
- Drinking or using before social events, meetings, or crowded places
- Rising tolerance as the calming effect wears off sooner
- Sharper restlessness, racing thoughts, or panic during withdrawal
2. Depression and substance use
Depression and substance use connect through motivation, because low energy makes anything that improves mood quickly seem worth repeating. Repeated use deepens the low mood afterward, so 3 signs often follow.
- Drinking or using alone, often late at night
- Longer stretches of withdrawal from friends and family
- Sleep and appetite shifting in ways that follow substance use
3. Trauma-related concerns and substance use
Trauma-related concerns connect to substance use through avoidance, since substances dull distressing memories briefly. That relief never lasts, though, and the cycle can reinforce 3 common patterns.
- Using substances to blunt flashbacks, nightmares, or intrusive memories
- Avoiding people, places, and conversations tied to the event
- Anger, numbness, or startle reactions that intensify after use
4. Other mental health concerns
Other conditions overlap with substance use often enough to matter during mental health and co-occurring substance use treatment. Clinicians therefore screen the full range rather than stopping at one diagnosis, with 4 conditions appearing most often.
- Bipolar disorder, where substance use often tracks mood swings
- ADHD, which raises the risk of stimulant and cannabis misuse
- Psychotic disorders, where substance use can worsen symptoms
- Personality disorders, where substance use can complicate emotional regulation
What Are Some Possible Signs of Co-Occurring Concerns?
Possible signs can show up in emotional distress, daily responsibilities, relationships, and repeated attempts to change substance use. Here are eight signs worth noticing.
- Ongoing emotional distress alongside problematic substance use
- Increasing difficulty managing everyday responsibilities
- Changes in relationships
- Using substances to cope with difficult emotions
- Repeated attempts to change substance use without success
- Mood or behavioral changes associated with substance use
- Difficulty maintaining work, school, or personal responsibilities
- Mental health concerns continuing alongside substance-related problems
One sign alone confirms nothing, since stress, grief, or illness can produce a similar picture. Clinicians therefore weigh how long the pattern lasts, how severe it becomes, and how the signs relate to substance use before drawing conclusions.
Why Is It Important to Address Mental Health and Substance Use Together?
Treating both concerns together matters because one can make the other worse. If only one gets treated, the other may keep causing problems.
According to NIDA, treating a substance use disorder and a mental health disorder at the same time usually works better than treating them separately. The two can feed into each other. For example, untreated anxiety may increase the urge to use substances, while continued use can make emotional recovery harder. Looking at the whole person, instead of only one diagnosis, gives treatment a better place to start.
Treating both at the same time also helps the care team see how they affect each other. They can notice when medication does not mix well with substance use, when a coping skill stops working under stress, or when a symptom may be caused by withdrawal. Those details help therapists, prescribers, and case managers work from one shared plan.
What Is Integrated Treatment for Co-Occurring Disorders?
Integrated treatment addresses both concerns in one program, with one team and one plan. Instead of sending someone between different providers, it keeps assessment, therapy, and medication connected. Most mental health and co-occurring substance use treatment includes 4 main parts.
1. Mental health support
Mental health support often includes therapy, but the type depends on how much support someone needs. Treatment may include individual sessions, group therapy, and skills groups.
- Individual counseling two or three times a week
- Group therapy using CBT, DBT, and ACT
- Skills groups focused on expressive arts, communication, and internal family systems
2. Substance use treatment
Substance use treatment focuses on substance use and the triggers behind it. Recovery coaching and relapse prevention are a big part of the work. Treatment may include:
- One-on-one recovery coaching with a dedicated coach
- Relapse prevention planning based on real triggers
- Motivational interviewing for mixed feelings about changing substance use
- Family involvement when it helps build support at home
3. Medication management when appropriate
Medication management starts with a psychiatric provider reviewing symptoms, medical history, and current substance use. Medication may then be prescribed when it can help. The provider also looks at 4 main areas:
- Medication for conditions such as depression or anxiety
- Medication for opioid use disorder when appropriate
- Regular checks for side effects
- Dose changes as symptoms change
4. Behavioral and coping skills
Behavioral and coping skills help people use what they learn in daily life. These skills improve with practice so that treatment may include activities such as:
- Stress management through yoga, music, and art
- Job and academic coaching before returning to work or school
- Vocational and volunteer opportunities that help rebuild routine
- Physical activity like gym sessions and hiking
What Happens During an Assessment for Co-Occurring Concerns?
An assessment reviews both concerns together before anyone builds a plan. Here are the six areas it covers.
| Assessment area | What the clinician reviews |
| Mental health concerns | Current symptoms, duration, and severity |
| Substance use patterns | Substances, frequency, recent shifts |
| Physical and behavioral health | Medical history, sleep, medications |
| Daily functioning | Work, school, home, self-care |
| Treatment history | Past programs and current needs |
| Level of care | Whether PHP, IOP, or OP fits |
When Should Someone Consider Professional Support?
Someone should consider professional support once the same problems keep returning despite honest attempts to fix them. Here are 7 areas worth checking.
- Daily life becomes harder to manage
- Relationships suffer from repeated conflict
- Work or school performance drops
- Physical or emotional health keeps getting worse
- Responsibilities become harder to keep up with
- Attempts to cut back on substance use do not work
- Overall quality of life continues to decline

Frequently Asked Questions (FAQs)
Q1. How can I manage co-occurring disorders?
Manage them by treating both concerns at once under one care team. Beyond therapy and any prescribed medication, daily coping practice and close family support keep progress steady, especially through the first few months.
Q2. What are the most common co-occurring mental disorders?
Anxiety and depression appear most often alongside substance use. Post-traumatic stress disorder follows closely, while bipolar disorder, ADHD, and psychotic disorders also appear.
Q3. What are three common disorders that co-occur with substance use disorder?
Anxiety, depression, and post-traumatic stress disorder are the three most common ones. Each can drive substance use and worsen afterward, so a full assessment covers all three.
Q4. Why does getting help sooner matter?
Getting help sooner keeps the problem smaller, since symptoms and substance use influence each other over time. Early support also protects work, relationships, and health before lasting damage sets in.
