Anxiety and Substance Use: When Two Separate Problems Occur Together

Anxiety and substance use are often discussed together, but they are not the same condition.

A person can have an anxiety disorder without having a substance use disorder. Likewise, someone can experience problematic alcohol or drug use without having a separate anxiety disorder.

Sometimes, however, both conditions occur at the same time.

When a mental health disorder such as anxiety and a substance use disorder are both present, clinicians generally refer to them as co-occurring disorders or a dual diagnosis.

Understanding this distinction matters. Effective treatment begins by identifying what is actually happening rather than assuming that every anxious feeling is caused by substance use or that every episode of alcohol or drug use is simply an attempt to manage anxiety.

Why Do Anxiety and Substance Use Sometimes Occur Together?

There is no single explanation.

For some people, anxiety symptoms begin first. Alcohol or drugs may initially seem to provide temporary relief from worry, panic, social discomfort, racing thoughts, or other distressing symptoms.

For example, a person with social anxiety may begin drinking before business events because alcohol makes conversation feel easier. Someone else may use cannabis in the evening because it seems to quiet persistent worry.

Over time, however, using substances to manage difficult emotions can become increasingly frequent or difficult to control.

For other people, substance use begins first. Alcohol, cannabis, stimulants, sedatives, opioids, and other substances can affect mood, sleep, heart rate, concentration, and the nervous system. Intoxication, repeated use, or withdrawal may create or intensify symptoms that resemble anxiety.

In still other cases, anxiety and problematic substance use may develop through overlapping biological, psychological, environmental, genetic, or stress-related factors.

For these reasons, it is often more useful to seek a careful clinical assessment than to conclude:

“My anxiety caused my drinking.”

or

“The drugs caused all of my anxiety.”

Either statement may contain some truth in an individual case, but the relationship should be evaluated rather than assumed.

What Does “Self-Medicating Anxiety” Mean?

The term self-medication is often used when someone turns to alcohol or drugs in an attempt to reduce emotional distress.

A person experiencing panic, social anxiety, chronic worry, or severe tension may discover that a substance provides temporary relief.

The problem is that short-term relief is not the same as treatment.

Repeated reliance on alcohol or drugs may eventually contribute to additional problems involving:

• Tolerance
• Withdrawal
• Sleep disruption
• Mood instability
• Relationship conflict
• Work difficulties
• Physical health
• Increasing difficulty coping without the substance

A pattern can develop in which anxiety contributes to substance use, substance use produces temporary relief, and the consequences or aftereffects of use create even more anxiety.

In simplified form:

Anxiety → substance use → temporary relief → rebound symptoms or consequences → increased anxiety → more substance use

This cycle does not occur for everyone, but when it does, addressing only one side of the problem may leave an important part of the clinical picture untreated.

Can Alcohol Make Anxiety Worse?

Yes.

Alcohol may initially feel calming because it affects the central nervous system. As alcohol leaves the body, however, some people experience increased nervous-system activity, irritability, disrupted sleep, shakiness, racing thoughts, or heightened anxiety.

For someone who already experiences significant anxiety, this can create a confusing cycle in which alcohol appears to help in the short term while worsening symptoms later.

Frequent or heavy alcohol use may also lead to withdrawal symptoms when drinking is reduced or stopped.

Alcohol withdrawal can be medically dangerous and, in severe cases, life-threatening.

Anyone who drinks heavily or regularly and develops severe shaking, confusion, seizures, marked agitation, or other significant withdrawal symptoms should receive medical evaluation rather than attempting to manage withdrawal alone.

Can Drugs Cause Anxiety or Panic Symptoms?

Yes. Some substances can trigger or intensify anxiety symptoms.

Stimulants, for example, can increase heart rate, alertness, restlessness, and physical activation. For someone vulnerable to panic, these sensations may contribute to a panic episode.

Cannabis may feel calming to some people but can produce anxiety, paranoia, or panic-like symptoms in others.

Sedating substances may temporarily reduce anxiety, yet misuse can lead to dependence or withdrawal problems.

This is why anxiety symptoms occurring during intoxication, withdrawal, or heavy substance use do not automatically establish the presence of a separate anxiety disorder.

A careful assessment can help clarify what is contributing to the symptoms.

How Do Clinicians Determine Whether Anxiety Is a Separate Disorder?

This is not always easy to determine from symptoms alone.

A clinician may consider questions such as:

• Did significant anxiety exist before substance use began?
• Does anxiety continue during sustained periods without substance use?
• When do symptoms appear in relation to intoxication or withdrawal?
• Are there anxiety triggers unrelated to substances?
• Is there a history of panic attacks, generalized anxiety, social anxiety, trauma, or phobias?
• Has anxiety affected work, relationships, sleep, or daily functioning?
• What substances are being used, and how often?
• Are prescription medications involved?
• Is the person experiencing withdrawal?
• Are there medical conditions that could contribute to anxiety-like symptoms?
• Is there a family history of anxiety, addiction, or other mental health conditions?

Sometimes the relationship becomes clear relatively quickly. In other situations, clinicians may need to observe symptoms over time as substance use changes.

The goal is not to force every symptom into one diagnosis.

The goal is to understand each condition accurately enough to develop an appropriate treatment plan.

For someone whose primary concern is persistent anxiety without a substance use disorder, dedicated anxiety treatment may be the more appropriate

What Is a Dual Diagnosis?

A dual diagnosis refers to the presence of both a mental health disorder and a substance use disorder.

Examples may include:

• An anxiety disorder and alcohol use disorder
• Depression and opioid use disorder
• PTSD and stimulant use disorder
• Bipolar disorder and alcohol use disorder

Having anxiety and occasionally drinking alcohol does not automatically mean someone has a dual diagnosis.

Likewise, experiencing anxiety after using a stimulant does not automatically establish a separate anxiety disorder.

Each condition should be evaluated independently.

This distinction helps prevent overdiagnosis while also reducing the likelihood that a genuine co-occurring condition will be overlooked.

Why Can Treating Only One Problem Be Difficult?

Consider someone who enters substance use treatment but also experiences severe, untreated panic attacks.

If the panic symptoms remain unaddressed, the person may continue experiencing one of the factors that previously contributed to substance use.

Now consider the reverse situation.

Someone may enter treatment for anxiety while significant alcohol or drug use goes unidentified. Substance use can interfere with sleep, medication, emotional regulation, therapy participation, and even the accurate assessment of anxiety symptoms.

When both conditions are genuinely present, treating them as unrelated problems can fragment care.

A more effective approach is to identify both conditions and understand how they interact for that individual.

What Does Integrated Dual Diagnosis Treatment Mean?

Integrated treatment does not mean treating anxiety and addiction as though they are the same disorder.

It means recognizing both conditions and coordinating care appropriately.

Depending on the individual’s needs, treatment may include:

• Comprehensive biopsychosocial assessment
• Individual therapy
• Group therapy
• Substance use treatment
• Anxiety-focused treatment
• Psychiatric evaluation
• Medication management when appropriate
• Relapse-prevention planning
• Family involvement
• Sleep and stress-management strategies
• Case management
• Continuing care

Some individuals may also benefit from the structure of an intensive outpatient program when symptoms require more support than traditional weekly therapy but do not require 24-hour residential care.

What About Anxiety Medication When Substance Use Is Present?

Medication may be appropriate for some people with anxiety disorders.

However, medication decisions require careful clinical consideration when a substance use disorder is also present.

Different anxiety medications have very different risk profiles.

Certain benzodiazepines, for example, can cause dependence and may create serious risks when combined with alcohol, opioids, or other sedating substances.

Other treatments, including certain antidepressant medications and non-medication approaches, may be more appropriate depending on the person’s diagnosis, symptoms, substance-use history, medical condition, and individual circumstances.

Medication decisions should therefore be individualized and coordinated with qualified prescribing professionals.

Signs It May Be Time for a Co-Occurring Disorders Evaluation

Consider seeking professional evaluation if:

• Anxiety is persistent or interfering with daily life
• Alcohol or drugs are increasingly being used to cope with anxiety
• Attempts to reduce substance use repeatedly fail
• Anxiety worsens after drinking or using drugs
• Panic symptoms occur during intoxication or withdrawal
• Substance use is affecting relationships, work, health, or responsibilities
• Anxiety continues during periods without substance use
• Increasing amounts of a substance are needed to achieve the same effect
• Cravings or withdrawal symptoms are present
• Mental health treatment has not helped as expected and significant substance use is also present
• Substance use treatment has not addressed persistent anxiety symptoms
• Family members or clinicians are concerned about both conditions

You do not need to determine on your own whether the problem is “really anxiety” or “really addiction.”

That is one purpose of a comprehensive evaluation.

If the primary concern is escalating alcohol or drug use, PCI’s guide to when it may be time to consider addiction treatment discusses warning signs in greater detail.

What If I Only Have Anxiety?

Then treatment should remain focused on anxiety.

This distinction is important.

Someone should not be placed into an addiction framework simply because they experience anxiety.

PCI provides a separate mental health treatment program for people experiencing anxiety, depression, trauma, and other mental health conditions when a substance use disorder is not part of the clinical picture.

What If I Have a Substance Use Disorder but Not an Anxiety Disorder?

The same principle applies.

Someone may need addiction treatment without having a separate anxiety diagnosis.

An effective assessment should identify actual treatment needs rather than adding diagnoses simply because certain conditions commonly occur together.

That is what makes the concept of co-occurring disorders meaningful:

Two distinct conditions are present at the same time.

“Let’s find out what is actually happening.”

Concerned About Both Anxiety and Substance Use?

If anxiety and alcohol or drug use appear to be occurring together, a professional assessment can help determine whether one condition, two separate conditions, or another clinical issue is contributing to the symptoms.

PCI Centers can evaluate mental health and substance use concerns independently while also determining whether integrated dual diagnosis treatment may be appropriate.
