You Don’t Have to Figure Out Which Came First
Most people who come to us aren’t sure which came first. They’ve been using alcohol, cannabis, or something else for years, telling themselves it’s just to take the edge off, just to sleep, just to get through the day. At some point the “just” stops being convincing. The drink that used to help for a few hours now barely touches it, the anxiety is worse than it’s ever been, and there’s a creeping suspicion that the two things are connected in a way that isn’t going to resolve on its own.
That suspicion is usually right. Anxiety disorders and substance use disorders are among the most common co-occurring conditions we treat, not because they happen to show up in the same person by coincidence, but because of how they interact neurologically, each one feeding and maintaining the other in ways that make treating only one side of the equation almost always insufficient.
How Common Is It to Have Both Anxiety and Addiction?
More common than most people realize. Anxiety and substance use disorders commonly occur together, and among people treated for anxiety disorders, an estimated 20% to 40% also have alcohol use disorder. The anxiety disorders most commonly seen alongside addiction include:
- Generalized anxiety disorder (GAD). Persistent worry and tension may lead some people to use alcohol or drugs in an attempt to relax or quiet anxious thoughts.
- Social anxiety disorder. Alcohol is often used to reduce discomfort in social situations, but repeated use can reinforce both the anxiety and the drinking.
- Panic disorder. Benzodiazepines may be prescribed for severe panic symptoms, and ongoing use can lead to dependence.
- Post-traumatic stress disorder (PTSD). Some people turn to drugs or alcohol to cope with intrusive memories, hyperarousal, or sleep problems.
Anxiety may contribute to substance use as a form of short-term relief, while repeated use can worsen anxiety symptoms over time, which is part of why both conditions so often need to be addressed together.
Why Anxiety and Addiction Feed Each Other
Substances work, at least in the short term. Alcohol, benzodiazepines, cannabis, and opioids can all reduce anxiety through real neurological mechanisms, which is worth acknowledging honestly. The problem isn’t that it worked once; it’s what the brain does with that information over time.
Tolerance is the first problem: the brain adapts to repeated exposure by downregulating its own anxiety-management systems, so the dose that worked six months ago stops working. Rebound anxiety is the second: when a substance wears off or is stopped, anxiety doesn’t just return to baseline, it can spike higher because the brain’s own calming capacity has been suppressed. Withdrawal-induced anxiety is one of the most common drivers of relapse we see, and it isn’t a character issue; the nervous system is in genuine physiological dysregulation.
Anxiety’s core behavioral mechanism is avoidance: the anxious brain labels a situation as threatening, the person avoids it, and the relief reinforces the idea that the situation really was dangerous. Substances make avoidance easier and more immediately rewarding, and over time the person’s world contracts. DBT is specifically built to interrupt this pattern, training the capacity to sit with discomfort without acting on it.
Which Substances Are Most Closely Linked to Anxiety
- Alcohol. A genuine short-term anxiolytic and a long-term anxiety amplifier. Regular drinking can deplete serotonin, disrupt sleep, and create a withdrawal state defined by anxiety and hyperarousal, including morning anxiety or a racing heart with no apparent cause. Alcohol’s disinhibiting effect can also mask social anxiety for years before the drinking itself becomes impossible to ignore.
- Cannabis. A genuinely complicated relationship: low doses of CBD-dominant cannabis can reduce anxiety for some people, but high-THC products, now dominant in the commercial market, are strongly associated with both acute panic and long-term anxiety in regular users.
- Benzodiazepines. Prescribed for anxiety, which gives their role here a particular cruelty: they work very well short-term and carry one of the highest dependency risks of any prescribed medication. Withdrawal-related anxiety can feel indistinguishable from “my anxiety is back,” so medically supervised detox matters here.
- Stimulants (cocaine, methamphetamine, Adderall). Can produce anxiety as a direct pharmacological effect, triggering a physiological state similar to a threat response. We often see a secondary substance, like alcohol or benzodiazepines, used to manage stimulant-induced anxiety, which reinforces use of both.
Why Treating One Without the Other Tends to Fail
Treat the addiction and leave anxiety untreated, and the untreated anxiety becomes the relapse trigger: sobriety holds until an anxiety-provoking situation arrives, and the person has no tools except the one they’ve been using for years. Treat the anxiety and leave the addiction untreated, and ongoing substance use interferes with the brain’s ability to respond to therapy, since CBT and DBT both depend on a functioning prefrontal cortex that chronic use impairs. Integrated treatment means both conditions are addressed from day one, by the same clinical team, within one coordinated plan.
How GBAC Treats Anxiety and Addiction Together
Every client who comes to us with a substance use disorder is assessed for co-occurring conditions, including anxiety, from the start. Treatment isn’t structured as “get sober first, then address the anxiety.” Both are in the room from day one.
DBT is central to how we work with this combination: mindfulness interrupts the avoidance loop, distress tolerance gives concrete tools for moving through anxious moments without acting on them, emotional regulation rebuilds the capacity to manage intense feelings without substances, and interpersonal effectiveness helps with the social anxiety or conflict that often contributed to the use in the first place.
IOP and PHP provide the predictability that anxiety responds well to: the same schedule, the same clinical team, and clear expectations for each session, along with group therapy as a low-stakes place to practice interpersonal skills. For some clients, non-addictive medication, such as SSRIs, SNRIs, or buspirone, is also part of the plan, not as the primary intervention, but as something that makes engaging with therapy more possible.
Signs That Anxiety and Addiction May Be Co-Occurring
- Substances are used specifically in response to anxiety, before difficult conversations, social events, or stressful situations, rather than only recreationally.
- Attempts to cut back or stop are followed by noticeably increased anxiety, restlessness, or physical symptoms.
- Anxiety treatment has been tried and hasn’t worked as well as expected, possibly because ongoing substance use is part of the reason.
- Morning anxiety is a consistent experience, particularly after drinking the night before.
- Social situations have become progressively harder to manage without a substance, or are avoided entirely.
- There’s a history of trauma that hasn’t been fully addressed.
- Previous addiction treatment ended in relapse connected to stress or an anxiety-provoking situation.
If several of these feel familiar, a dual diagnosis evaluation may be worth pursuing.
Does Insurance Cover Anxiety and Addiction Treatment?
Many private plans cover medically necessary treatment, though deductibles, copays, coinsurance, and authorization requirements vary by plan. We work with most major insurers and verify your benefits for free; checking doesn’t commit you to treatment.
Talk to Someone Who Can Help You Take the Next Step
That question, whether the anxiety caused the drinking or the drinking caused the anxiety, comes up in almost every intake conversation we have. It rarely has a clean answer, and it doesn’t need one: both are present, both are treatable, and treating them together produces meaningfully better outcomes than treating either one alone.

Frequently asked questions
Can anxiety cause addiction?
It can contribute to it. Many people use alcohol, cannabis, or other substances to quiet anxious thoughts or ease discomfort in social situations, and over time that pattern can turn into dependence.
Can you treat anxiety and addiction at the same time?
Yes, and that's the standard of care. Treating only the addiction leaves untreated anxiety as a relapse trigger, and treating only the anxiety while substance use continues makes therapy like CBT and DBT less effective, since chronic use impairs the brain functions those therapies depend on.
Does anxiety go away when you get sober?
Not automatically. In the short term, anxiety can actually spike during withdrawal as the brain's own calming systems recover. That's part of why integrated treatment, not just detox, matters.
What type of therapy works best for anxiety and addiction?
Dialectical behavior therapy (DBT) is central to how we treat this combination, since its skills directly target the avoidance patterns that keep anxiety and substance use connected. CBT and, for some clients, non-addictive anxiety medication can also be part of the plan.
Is anxiety and addiction treatment covered by insurance in Massachusetts?
Many private plans cover medically necessary treatment, though deductibles, copays, coinsurance, and authorization requirements vary by plan. We verify your benefits for free before you commit to anything.
