What If Substance Use Is An Attempt To Regulate A Dysregulated Nervous System?

Most of us reached for something to change how we felt long before we understood what we were actually feeling.


That distinction matters far more than we’ve been taught to believe.

Because the conversation around substance use (in our culture, in most clinical settings, in the stories we tell ourselves) tends to collapse quickly into judgment. Into categories of weak and strong, sick and well, addicted and not. What it rarely does is ask the more honest question underneath:

What state were you trying to escape from? And why didn’t you have another way out?

I’ve thought about this for a long time. And I think for many of us, what gets labeled as addiction, or weakness, or moral failure, is actually something more fundamental and more human than any of those words suggest.

It’s a nervous system looking for relief.

And a person who was never taught how to find it any other way.

The mechanism That Goes Unnamed

Carl Jung wrote that every form of addiction is “bad,” regardless of whether the narcotic is alcohol, morphine, or idealism. But he also understood something that gets lost in the modern conversation- that what we call shadow, what we push underground, what we refuse to integrate consciously, will find its expression regardless. The psyche moves toward wholeness. When the direct path is blocked, it finds another route.

Substances are often that route.

Not because people are inherently flawed. But because the nervous system will always seek regulation. It is designed to. And when the internal tools for self-regulation were never developed (when the environment that should have modeled emotional attunement instead modeled suppression, distance, or chaos) the system learns to reach outward for what it cannot find within.

Sometimes we drink because it softens the specific anxiety of being around other people when we never learned to feel safe in connection. Sometimes we smoke because it quiets the tension that’s been living in the chest for so long we’ve stopped noticing it consciously. Sometimes we use stimulants because we are profoundly disconnected from our own aliveness and need something external to remind us we exist. Sometimes we scroll, work, eat, gamble, catastrophize, or chase the intensity of unstable relationships for the exact same reason.

Different behaviors. Same mechanism.

The nervous system reaching for a change in state because the current state has become unbearable or because the current state has become so normalized that we can’t even feel it anymore without help.

The window that keeps shrinking

Dan Siegel’s concept of the window of tolerance gives us useful language here. Every nervous system has a functional range- a zone where we can think clearly, regulate emotion, handle uncertainty, stay present. Inside that window, we have access to ourselves.

But the window is not fixed. It contracts under load.

Chronic stress, sleep deprivation & grief contracts it. Financial fear, physical inflammation, relational activation, prolonged uncertainty- all of it contracts the window. And as the window shrinks, our capacity shrinks with it. Things that were manageable become overwhelming. The distance between activation and reaction collapses. The reach for relief becomes faster, more automatic, less chosen.

This is not a weakness on our system. It is biology responding to accumulating load.

And when we add the layer of growing up in an IEC environment- where the window was never allowed to fully develop because the co-regulation that builds it was inconsistently available- we begin with a smaller window to begin with. We’ve always been working with less margin than people raised in more emotionally stable environments. And we’ve often been judging ourselves against a standard that was never calibrated for our actual starting point.

What Is The IECIB Framework?

Disconnected from the signal

One of the stranger consequences of growing up in emotionally inconsistent environments is how thoroughly disconnected we can become from our own interior.

We can carry stress in the body for months- tension in the sternum, chronic inflammation, disrupted sleep, a low hum of anxiety underneath everything- & barely register it consciously. Not because we are insensitive or incapable. Often because we are extraordinarily sensitive, and we learned early to turn that sensitivity outward rather than inward. To read rooms & track other people. To manage environments & to stay functional.

But not to feel the truth within ourselves.

Interoception- our capacity to sense and interpret the internal signals of the body is- a learnable and losable skill. In environments where our internal signals were consistently overridden, dismissed, or simply never acknowledged, we lose access to them. The channel goes quiet from disuse.

So we often don’t realize we’re dysregulated until we’re already reaching for something to change it. The awareness comes after the impulse. The behavior precedes the understanding.

This is not moral failure. This is a nervous system operating without adequate internal instrumentation, doing its best to navigate by whatever external signals it can find.

What Interoception Is And Why It Matters

When even good things activate us


This took me a long time to understand honestly in myself.

Relationships activate the nervous system. Not just difficult ones. Not just chaotic or inconsistent ones. Intimacy itself activates things- vulnerability, the fear of being seen and found lacking, the ancient dread of connection being withdrawn. Even in relationships that are genuinely good, genuinely caring, genuinely different from what we knew before- old patterns wake up. Old fears surface. The nervous system, calibrated to a particular kind of emotional environment, interprets closeness as potential threat before it can register it as actual safety.

And sometimes substances become the bridge. A way to soften the intensity of vulnerability enough to stay open. A way to quiet the noise of old fear enough to be present with someone we actually want to be present with.

Understanding this is not permission to keep using that bridge indefinitely. But it changes the nature of what we’re actually working with. We’re not working with weakness or addiction as a primary problem. We’re working with a nervous system that hasn’t yet learned to feel safe in connection without assistance.

That is workable. That is something that can change.

When the substance is holding a life in place

Jung also wrote about the transcendent function- the psyche’s drive toward integration, toward bringing what is unconscious into consciousness. He believed that symptoms, however uncomfortable, were often the psyche’s attempt to communicate something that hadn’t been heard any other way.

Viewed through that lens, persistent substance use sometimes carries a different message than we assume.

Sometimes it’s holding a life in place that the deeper self is already trying to leave. Many times it’s the thing making an environment, a relationship, a version of ourselves tolerable- that our nervous system is actually telling us, clearly and consistently, is not aligned.

The honest questions then aren’t about willpower. They’re about what we’re sustaining. What we’re overriding. What we’re forcing ourselves through that might deserve a different response. What part of us has been trying to communicate something that we keep quieting with the next thing that brings relief.

Not from shame. From genuine curiosity.

Because oftentimes the substance isn’t the core problem.

Sometimes the substance is the most creative solution our nervous system found to a problem we haven’t yet named.

Where awareness actually begins


Real change (not forced change, not shame-driven change, not white-knuckled behavioral modification) starts with understanding the mechanism underneath the behavior.

It starts with slowing down enough to notice what actually precedes the reach. What state we’re in before the impulse arrives. What the body is carrying. What the nervous system is trying to communicate. What the behavior has been, all along, attempting to solve.

Most of us were taught to judge the behavior. Rarely were we taught to get genuinely curious about what it was trying to do.

But awareness changes the relationship to the pattern. Not immediately or completely. But meaningfully.

When we can feel the activation before we automatically respond to it (when we can name what the nervous system is reaching for and why) we have something we didn’t have before.

A moment of choice.

And from that moment, however small, real change becomes possible.

It isn’t about instantly becoming a perfect version of ourselves or old patterns vanishing overnight.

Just the beginning of understanding ourselves clearly enough to find our way toward something better.

That’s where it starts. That’s always where it starts.
