Anxiety is your body’s natural response to perceived danger, stress, or uncertainty. It often shows up as feelings of fear, nervousness, or dread, along with physical symptoms like a racing heart, tight chest, or upset stomach.(Source)

Everyone experiences anxiety at times—before a big move, a job interview, a medical test, or a major life change. In many situations, this kind of short-term anxiety is normal and even helpful, because it can keep you alert and motivated.

An anxiety disorder is different. With an anxiety disorder, worry and fear are more intense, last longer, and begin to interfere with daily life, relationships, work, or school.(Source) You may feel anxious most days, even when there is no clear reason, or your reactions may feel out of proportion to the situation.

If anxiety is making it hard to function, causing you to avoid people or places, or pushing you toward alcohol or drugs to cope, it may be time to seek professional support.

Anxiety disorders are a group of related conditions that share features of excessive fear, worry, and physical tension, but they can look very different from person to person.(Source)

Below are some of the most common types of anxiety-related disorders we see and treat in connection with substance use.

Generalized Anxiety Disorder (GAD)

People with generalized anxiety disorder experience persistent, excessive worry about everyday things—health, finances, work, family, or the future—even when there is little or no clear reason for concern.(Source) The worry can feel uncontrollable and is often accompanied by symptoms like restlessness, fatigue, muscle tension, irritability, and trouble sleeping.

Because the anxiety is so constant, some people turn to alcohol, prescription medications, or illicit drugs to try to calm their nerves or “shut off” their thoughts, which can quickly lead to dependence.

Obsessive-Compulsive Disorder (OCD)

Obsessive-compulsive disorder involves intrusive, unwanted thoughts, images, or urges (obsessions) that create intense anxiety, and repetitive behaviors or mental rituals (compulsions) that a person feels driven to perform to reduce that anxiety.(Source)

Examples include:

• Repeated handwashing or cleaning due to fears of contamination
• Checking doors, stoves, or locks over and over
• Counting, arranging, or repeating phrases until it “feels right”

These rituals may temporarily reduce distress, but they can become time-consuming and disruptive. Some individuals with OCD may misuse substances to escape obsessive thoughts or to cope with the stress of their rituals.

Trauma- and Stressor-Related Disorders

Trauma- and stressor-related disorders develop after a major stressor or traumatic event, such as a serious accident, natural disaster, assault, combat, sudden loss, or chronic exposure to abuse.(Source)

Common trauma- and stress-related conditions include:

• Post-Traumatic Stress Disorder (PTSD) – Involves intrusive memories or flashbacks, nightmares, avoidance of reminders of the trauma, negative changes in mood and thinking, and heightened startle or hypervigilance.(Source)
• Acute Stress Disorder – Similar to PTSD but occurs in the first month after a traumatic event.(Source)

Many people with PTSD or other trauma-related disorders use alcohol or drugs to numb painful memories, reduce nightmares, or help them sleep, which can lead to a dangerous cycle of dependence.

Panic Disorder

Panic disorder is characterized by recurrent, unexpected panic attacks—sudden surges of intense fear or discomfort that peak within minutes and may include chest pain, shortness of breath, dizziness, trembling, or a fear of losing control or dying.(Source)

Because panic attacks can feel like a medical emergency, people often begin to fear having another attack and may avoid certain places or situations. Some turn to substances to try to prevent or manage these episodes.

Social Anxiety Disorder

Social anxiety disorder involves intense fear or anxiety about social situations where a person might be judged, embarrassed, or scrutinized by others.(Source) This can include speaking in public, meeting new people, eating in front of others, or even everyday conversations.

People with social anxiety may avoid social events altogether or rely on alcohol or drugs to feel more relaxed or confident in social settings, which can increase the risk of addiction.

Specific Phobias

Specific phobias are intense, irrational fears of particular objects or situations—such as flying, heights, needles, animals, or enclosed spaces—that lead to avoidance and significant distress.(Source)

Separation Anxiety Disorder

Separation anxiety disorder involves excessive fear or distress about being away from home or from major attachment figures, such as a parent, partner, or child.(Source) While often associated with children, it can also affect adults and may be linked with other anxiety or mood disorders.

Anxiety disorders can affect the body, thoughts, emotions, and behavior. Not everyone will experience the same symptoms, and their intensity can vary over time.

Common symptoms include:(Source)

• Constant fear, worry, or a sense of impending doom
• Trouble falling or staying asleep, or restless, unsatisfying sleep
• Difficulty concentrating or feeling like your mind goes blank
• Rapid breathing or shortness of breath
• Elevated heart rate or heart palpitations
• Muscle tension, restlessness, or feeling “on edge”
• Digestive issues, nausea, or stomach discomfort
• Sweaty, cold, or clammy hands and feet
• Frequent nightmares or disturbing dreams
• Repetitive, distressing thoughts or memories that are hard to control
• Avoidance of people, places, or situations that trigger anxiety

When you seek help, a medical or mental health professional will typically start by ruling out underlying medical conditions (such as thyroid problems, heart issues, or medication side effects) that can mimic or worsen anxiety symptoms.(Source)

If you recognize several of these symptoms in yourself or a loved one—especially if they are interfering with daily life—it may be time to consider a professional evaluation.

Anxiety is not “just in your head.” Chronic, untreated anxiety can contribute to real physical changes in the body.

Long-term anxiety is associated with:

• Changes in stress hormones and the autonomic nervous system
• Increased inflammation in the body
• Disruptions in immune system functioning
• Elevated blood pressure and heart rate
• Higher risk of cardiovascular problems over time(Source)

People with anxiety disorders are more likely to experience conditions such as high blood pressure, heart disease, gastrointestinal problems, and chronic pain.(Source) Anxiety can also contribute to weight changes, sleep disturbances, and reduced quality of life.

Addressing anxiety early—especially when it co-occurs with substance use—can help protect both your mental and physical health.

Anxiety disorders are among the most common mental health conditions in the United States, affecting an estimated 19% of adults each year.(Source) Many of those individuals also struggle with alcohol or drug use.

People living with anxiety may turn to substances to:

• Calm racing thoughts or physical tension
• Feel more confident in social situations
• Fall asleep more easily
• Numb painful memories or emotions

This pattern is known as self-medication. While substances may provide short-term relief, they often make anxiety worse over time and can lead to addiction.(Source)

Substance use can:

• Intensify anxiety during intoxication or withdrawal
• Disrupt sleep and mood regulation
• Trigger panic attacks or paranoia
• Interfere with medications or therapy for anxiety

When anxiety and substance use occur together, they are referred to as co-occurring disorders or a dual diagnosis.(Source) Treating only one condition while ignoring the other often leads to relapse or worsening symptoms, which is why integrated care is so important.

Anxiety disorders and substance use disorders frequently overlap for several reasons.

Genetic and Family Predisposition

If you have a family history of anxiety, depression, or substance use disorders, you may be more vulnerable to developing one or both conditions yourself.(Source) Genetics, early life experiences, and learned coping patterns can all play a role.

Effects of Substance Use and Withdrawal

Many substances can cause or worsen anxiety, especially during withdrawal. For example:

• Alcohol withdrawal can lead to severe anxiety, restlessness, and tremors.
• Stimulants (like cocaine or methamphetamine) can trigger panic, paranoia, and agitation.
• Cannabis, especially in high doses or high-THC products, can increase anxiety or cause panic in some people.(Source)

Over time, the brain adapts to repeated substance use, and anxiety symptoms can become more intense when the substance is not present.

Biochemical and Brain Changes

Both anxiety disorders and addiction involve changes in brain regions and neurotransmitters that regulate stress, reward, and decision-making.(Source) These overlapping pathways can make it harder to manage emotions, resist cravings, or feel pleasure from everyday activities.

Because of these shared biological and psychological factors, anxiety and substance use often reinforce each other, creating a cycle that can be difficult to break without professional support.

A dual diagnosis (also called co-occurring disorders) means a person is living with both a substance use disorder and at least one mental health condition, such as an anxiety disorder, depression, PTSD, or bipolar disorder.(Source)

Dual diagnosis is common. Many people who enter addiction treatment discover they have an underlying anxiety disorder that has been driving their substance use for years.

Effective dual diagnosis treatment focuses on:

• Accurately identifying all mental health and substance use issues
• Treating anxiety and addiction at the same time, not one after the other
• Using therapies and medications that support both conditions rather than worsening either one

At Cardinal Recovery, our team works collaboratively to create integrated treatment plans that address the full picture of your mental health and substance use, so you are not left choosing between treating your anxiety or your addiction.

Anxiety disorders are highly treatable, especially when care is tailored to your unique needs and co-occurring conditions.(Source) At Cardinal Recovery, we combine evidence-based mental health care with comprehensive addiction treatment.

Treatment options may include:

Psychotherapy (Talk Therapy)

• Cognitive Behavioral Therapy (CBT) – Helps you identify and change unhelpful thought patterns and behaviors that fuel anxiety and substance use.(Source)
• Exposure-Based Therapies – Gradually and safely help you face feared situations or memories, especially for phobias, social anxiety, and PTSD.(Source)
• Dialectical Behavior Therapy (DBT) Skills – Teach emotion regulation, distress tolerance, and mindfulness to manage intense anxiety and cravings.(Source)
• Trauma-Informed Therapy – Addresses the impact of past trauma on current anxiety and substance use in a safe, supportive environment.

Medication Management

For some people, medications can significantly reduce anxiety symptoms and support recovery from substance use disorders. Depending on your needs, a provider may consider:

• Certain antidepressants (such as SSRIs or SNRIs) for generalized anxiety, panic disorder, social anxiety, or PTSD(Source)
• Non-addictive anti-anxiety medications when appropriate

Because some medications used for anxiety (such as benzodiazepines) carry a risk of dependence, careful evaluation and monitoring are essential, especially for individuals with a history of substance use.(Source)

Complementary and Holistic Approaches

Many people benefit from integrating holistic practices into their treatment plan, such as:

• Mindfulness and meditation
• Breathing and relaxation techniques
• Yoga or gentle movement
• Sleep hygiene and lifestyle changes

These approaches can help calm the nervous system, improve emotional regulation, and support long-term recovery when combined with professional care.(Source)

Our team will work with you to determine which combination of therapies is safest and most effective for your specific situation.

If you or a loved one are struggling with anxiety and addiction, you do not have to face it alone. Both conditions are medical illnesses—not personal failures—and both can be treated.(Source)
