If you’ve ever reached for a drink to calm your nerves or relied on substances to get through a stressful day, you’re not alone. Many people in Phoenix and across the country quietly struggle with the overlap between anxiety and addiction. These two challenges are deeply connected, and understanding that connection is one of the most important steps toward healing.

Anxiety is one of the most common mental health conditions in the United States. It shows up in many forms — racing thoughts, a tight chest, constant worry, or a sense of dread that never quite goes away. When those feelings become overwhelming, some people turn to alcohol or other substances to find relief. Over time, that pattern can quietly spiral into dependence.

At Milestone Recovery, we see this connection every day. Our compassionate team understands that substance use is often a response to pain, not a character flaw. With the right support, it is possible to address both anxiety and addiction at the same time.

Why Anxiety and Substance Use So Often Occur Together

The relationship between anxiety and substance use isn’t a coincidence. Research consistently shows that people with anxiety disorders are at a significantly higher risk of developing a substance use disorder. Similarly, people who struggle with addiction are far more likely to experience anxiety. This back-and-forth cycle is known as a co-occurring disorder, sometimes called a dual diagnosis.

Understanding why this happens requires a closer look at how anxiety affects the brain and behavior.

The Brain’s Search for Relief

When someone experiences anxiety, their nervous system goes into overdrive. The brain floods the body with stress hormones like cortisol and adrenaline. This response is meant to protect us from danger. However, in people with chronic anxiety, it can feel relentless and exhausting.

Alcohol, benzodiazepines, cannabis, and other substances can temporarily slow down that overactive stress response. They create a short-term sense of calm. Because of this, the brain begins to associate those substances with relief. Over time, the person needs more of the substance to get the same calming effect. That is how dependence can quietly develop.

When Substance Use Makes Anxiety Worse

Here is where the cycle becomes especially difficult. While substances may reduce anxiety in the short term, they often make it significantly worse over time. Alcohol, for example, disrupts the brain’s natural chemistry. As it wears off, the nervous system becomes even more reactive. This rebound effect can trigger heightened anxiety, panic, and restlessness — the very feelings the person was trying to escape.

Moreover, the shame and consequences that can come with substance use — strained relationships, work problems, financial stress — create additional layers of anxiety. The cycle feeds itself, and without outside support, it can feel nearly impossible to break.

Common Types of Anxiety Linked to Substance Use

Anxiety is not a single, one-size-fits-all experience. Several distinct anxiety conditions are closely associated with substance use disorders. Recognizing the specific type of anxiety someone is dealing with is an important part of creating an effective treatment plan.

Generalized Anxiety Disorder (GAD)

People with Generalized Anxiety Disorder experience persistent, excessive worry about everyday situations. Work, health, relationships, and finances can all feel like constant sources of dread. This chronic, low-level tension often pushes people toward substances as a way to quiet the mental noise. Additionally, GAD can be hard to recognize because the worry feels so tied to real life events.

Social Anxiety Disorder

Social anxiety involves intense fear of judgment, embarrassment, or rejection in social situations. Alcohol is frequently used to lower inhibitions and ease social discomfort — a practice sometimes called “liquid courage.” However, regular use to manage social situations can quickly lead to alcohol dependence.

Panic Disorder

Panic attacks are sudden, intense waves of fear that can include a racing heart, shortness of breath, chest pain, and a feeling of losing control. They are terrifying to experience. People who live with panic disorder often use substances to try to prevent or dampen these episodes. Unfortunately, many substances actually increase the likelihood of panic attacks over time.

Post-Traumatic Stress Disorder (PTSD)

PTSD is closely related to anxiety and has a particularly strong connection to substance use. Trauma survivors often turn to substances to numb flashbacks, nightmares, and hypervigilance. At Milestone Recovery, we specialize in trauma-informed care and understand how deeply intertwined PTSD, anxiety, and addiction can be.

Treating Anxiety and Addiction Together: Why It Matters

One of the most important things to understand about co-occurring anxiety and addiction is this: treating only one condition while ignoring the other is rarely effective. If someone receives addiction treatment but their underlying anxiety goes unaddressed, the urge to self-medicate will likely remain strong. On the other hand, treating anxiety without addressing substance use misses a critical piece of the puzzle.

Integrated treatment — meaning care that addresses both conditions simultaneously — produces the best outcomes. At Milestone Recovery, every client receives a thorough assessment so we can understand the full picture of what they are experiencing.

Evidence-Based Therapies That Help

Several proven therapeutic approaches are effective for treating both anxiety and addiction at the same time. Our clinical team uses a combination of methods tailored to each person’s unique needs.

• Cognitive behavioral therapy (CBT): CBT helps clients identify and change the thought patterns that fuel both anxiety and substance use. It teaches practical coping skills that can replace the urge to use substances when anxiety spikes.
• Dialectical Behavior Therapy (DBT): DBT focuses on emotional regulation, distress tolerance, and mindfulness. It is especially helpful for people whose anxiety is tied to intense emotional responses.
• EMDR (Eye Movement Desensitization and Reprocessing): For those whose anxiety is rooted in trauma, EMDR can help process distressing memories so they no longer carry the same emotional charge.
• Medication-Assisted Treatment (MAT): In some cases, medication can play an important supportive role in managing anxiety symptoms during recovery. Our psychiatric team carefully evaluates each client’s needs.
• Mindfulness and Grounding Techniques: Learning to stay present and regulate the nervous system is a powerful tool for managing anxiety without substances.

The Role of PHP and IOP at Milestone Recovery

Not everyone needs the same level of care. That is why Milestone Recovery offers both a Partial Hospitalization Program (PHP) and an Intensive Outpatient Program (IOP).

Our PHP provides a structured, supportive environment with daily individual and group therapy, psychiatric assessments, and medication management. It is a strong fit for those who need intensive support without a residential stay. Our IOP offers a more flexible schedule — ideal for clients who are managing work and family responsibilities while still needing meaningful, consistent support.

Both programs are built around whole-person wellness. In addition to therapy, clients have access to nutritional education, fitness, outdoor activities, and animal-assisted therapy with our certified therapy dog, Luna. These elements aren’t extras — they are an important part of healing the nervous system and building a sustainable life in recovery.

Recognizing the Signs in Yourself or Someone You Love

It can be difficult to know when anxiety and substance use have crossed a line into something that needs professional attention. Here are some signs worth paying attention to:

• Using alcohol or other substances specifically to calm anxiety or manage stress
• Feeling unable to face certain situations without using a substance first
• Noticing that anxiety feels worse between uses or after stopping
• Increasing how much you use to get the same calming effect
• Feeling trapped in a cycle of anxiety and using, with no clear way out
• Withdrawing from activities or relationships due to anxiety or substance use

These signs don’t mean something is permanently wrong with you. They mean you may be dealing with something bigger than willpower alone can address — and that support is available.
