Understanding Dual Diagnosis: Mental Health and Substance Use
Mental health conditions and substance use disorders can occur separately, but they can also occur at the same time. When a person has both a substance use disorder and a co-occurring mental health disorder, clinicians may describe this as a dual diagnosis or co-occurring disorders.
The relationship is not always simple. Anxiety, depression, trauma symptoms or other mental health concerns may influence substance use. Alcohol or drugs can also worsen psychiatric symptoms, create substance-induced symptoms or make an existing condition more difficult to recognize.
Green Springs Wellness in Hillsborough, New Jersey provides dual diagnosis treatment for adults who need coordinated behavioral health care for substance use and co-occurring mental health concerns.
What Is a Dual Diagnosis?
A dual diagnosis means that a person has a substance use disorder and a separate mental health disorder at the same time. The mental health condition might involve anxiety, depression, PTSD, bipolar disorder or another diagnosable condition.
Having emotional distress while using substances does not automatically establish a dual diagnosis. An appropriate assessment considers symptoms, substance-use patterns, timing, medical history and whether symptoms continue outside periods of intoxication or withdrawal.
Substance Use Does Not Simply “Become” a Mental Health Disorder
Substances can trigger, imitate or worsen psychiatric symptoms, and mental health symptoms can influence substance use. Determining whether symptoms reflect a primary mental health disorder, substance effects or both can require careful clinical evaluation.
How Mental Health and Substance Use Can Interact
Using Substances to Cope
Someone may use alcohol or drugs in an attempt to manage anxiety, sadness, trauma symptoms, insomnia or other distress. Temporary relief can reinforce continued use without treating the underlying concern.
Substances Can Worsen Symptoms
Alcohol, stimulants, opioids and other substances can affect mood, sleep, anxiety, judgment and perception. Effects vary by substance, dose, pattern of use and individual factors.
Withdrawal Can Resemble Mental Health Symptoms
Withdrawal can involve anxiety, irritability, sleep disturbance, depressed mood and other symptoms that may complicate assessment.
One Condition Can Complicate the Other
Untreated psychiatric symptoms may make recovery more difficult, while ongoing substance use may interfere with mental health treatment and daily stability.
Common Examples of Co-Occurring Disorders
There is no single combination that defines dual diagnosis. Examples can include:
Depression and Alcohol Use Disorder
Alcohol may be used to cope with low mood while ongoing drinking can contribute to sleep problems, impaired functioning and worsening emotional symptoms.
Anxiety and Substance Use
Alcohol or drugs may be used to reduce worry or panic temporarily, but substance effects and withdrawal can also intensify anxiety.
PTSD and Substance Use Disorder
Some people use substances to avoid or blunt trauma-related distress, which can complicate recovery from both conditions.
Bipolar Disorder and Substance Use
Substance use can complicate mood symptoms, sleep, judgment and treatment adherence and may make symptom patterns harder to interpret.
Signs That a Dual Diagnosis Assessment May Be Helpful
1. You Regularly Use Substances to Change How You Feel
Alcohol or drugs have become a primary way to manage anxiety, sadness, trauma symptoms, anger, loneliness or sleep.
2. Mental Health Symptoms Continue When You Are Not Using
Depression, anxiety, intrusive thoughts, mood changes or other symptoms remain present outside periods of intoxication.
3. Substance Use Makes Psychiatric Symptoms Worse
You notice a recurring relationship between drinking or drug use and worsening mood, anxiety, paranoia, sleep or emotional instability.
4. Treatment for One Problem Has Not Been Enough
Addiction treatment is repeatedly disrupted by untreated mental health symptoms, or mental health treatment is complicated by continued substance use.
5. You Have Difficulty Cutting Back Despite Consequences
Substance use continues despite problems involving health, relationships, responsibilities or emotional well-being.
6. Symptoms Are Difficult to Separate
You are unsure whether anxiety, depression, sleep problems or mood changes are caused by a mental health condition, substances, withdrawal or some combination.
Primary Mental Health Symptoms vs. Substance-Induced Symptoms
This distinction can be clinically important, but it is not always possible to determine immediately.
Primary Mental Health Disorder
- Meaning
- A mental health disorder that exists independently of intoxication or withdrawal.
- Assessment May Consider
- Symptom history, timing, family history, periods without substance use and previous diagnoses.
Substance-Induced Symptoms
- Meaning
- Psychiatric symptoms that develop in relation to intoxication, medication or withdrawal.
- Assessment May Consider
- Which substance was used, timing of symptoms, dose, withdrawal and whether symptoms improve with sustained abstinence.
Co-Occurring Disorders
- Meaning
- A substance use disorder and an independent mental health disorder are both present.
- Assessment May Consider
- How the conditions interact and what treatment plan can address both.
Why Evaluation Matters
- Challenge
- Symptoms can overlap, change over time or be difficult to interpret during active substance use.
- Goal
- Build a treatment plan based on the full clinical picture rather than assumptions about which problem came first.
Why Treat Mental Health and Addiction Together?
Understand the Connection
Treatment can help identify how emotions, psychiatric symptoms, cravings and substance use influence one another.
Build Alternative Coping Skills
Clients can develop ways to respond to distress without automatically turning to alcohol or drugs.
Coordinate Recovery Goals
A unified treatment plan can consider mental health and substance use goals together rather than creating conflicting strategies.
Recognize Warning Signs
Treatment can help distinguish early changes in mental health from substance-use triggers and identify when additional support is needed.
Therapy and Support in Dual Diagnosis Treatment
Individual Therapy
Individual therapy can explore triggers, symptoms, coping patterns, relationships and recovery goals.
Cognitive Behavioral Therapy
CBT can help clients examine connections among thoughts, emotions and behaviors and practice alternative responses.
Group Therapy
Group treatment can provide structured skill-building, feedback, accountability and connection with others working through behavioral health challenges.
Trauma-Informed Care
A trauma-informed approach recognizes how trauma history may affect safety, trust, symptoms and engagement without assuming trauma is the cause of every substance use disorder.
Medication When Appropriate
Medication may be part of treatment for some mental health or substance use disorders. Prescribing decisions require individualized evaluation by an appropriately qualified medical professional.
Recovery and Aftercare Planning
Aftercare can help clients prepare for triggers, symptom changes and continued support as treatment becomes less intensive.
Levels of Care for Co-Occurring Disorders
Partial Hospitalization Program
PHP provides substantial daytime behavioral health structure while clients live outside the facility.
Intensive Outpatient Program
IOP provides structured treatment with greater flexibility for appropriate daily responsibilities.
Outpatient Treatment
Outpatient care provides ongoing therapeutic support with less weekly structure when clinically appropriate.
Higher Levels of Care
Some people may need medical detox, residential treatment, inpatient psychiatric care or emergency services before or instead of outpatient treatment. Green Springs Wellness does not provide those higher levels onsite.
Dual Diagnosis Treatment at Green Springs Wellness
Green Springs Wellness provides outpatient addiction and mental health treatment in Hillsborough, New Jersey. Treatment planning considers both substance use and co-occurring psychiatric symptoms when both are present.
The appropriate program depends on clinical needs, safety, functioning, substance-use patterns, mental health symptoms and whether a higher level of care is needed first.
Frequently Asked Questions About Dual Diagnosis
What does dual diagnosis mean?
Dual diagnosis generally refers to having both a substance use disorder and a co-occurring mental health disorder at the same time.
Can substance use cause mental health symptoms?
Yes. Intoxication and withdrawal can cause or worsen psychiatric symptoms. A clinical evaluation may be needed to determine whether symptoms are substance-induced, part of an independent mental health disorder or both.
Which mental health conditions can occur with addiction?
Substance use disorders can occur alongside many mental health conditions, including anxiety disorders, depression, PTSD, bipolar disorder and others.
Should addiction and mental health conditions be treated together?
When both conditions are present, coordinated treatment can address how they interact and help create a unified plan for symptoms, substance use and recovery.
How do clinicians know whether symptoms are caused by substances?
Assessment may consider symptom timing, substance use, withdrawal, periods of abstinence, medical and psychiatric history and whether symptoms persist when the substance is no longer affecting the person.

Green Springs Wellness provides outpatient behavioral health treatment for adults with substance use and co-occurring mental health concerns when its programs are clinically appropriate for their needs.
