The first map doesn’t ask how often you drink or whether you’ve tried to quit. It asks what your brain is doing on repeat.

Researchers George Koob and Nora Volkow describe addiction as a three-stage cycle that grows deeper with each turn: binge/intoxication, withdrawal/negative affect, and preoccupation/anticipation ⁶. Each stage lives in a different part of the brain, and each one gets stronger the more times you run the loop.

Stage one is the part most people picture when they hear the word “addiction” — the using itself. The substance hits the mesolimbic dopamine system, the brain’s reward circuit, and you feel relief, energy, calm, whatever it is you came for ⁶. Early on, this stage runs the show.

Stage two is the one nobody warns you about. When the substance leaves your system, the extended amygdala — the brain’s stress and threat center — turns up the volume ⁶. You feel anxious, irritable, flat, achy, off. Sunday mornings get heavier. The 3 p.m. crash gets sharper. You’re not just chasing the high anymore; you’re trying to stop feeling bad.

Stage three lives in the prefrontal cortex, the part of you that plans, weighs, and says no ⁶. As the cycle deepens, this circuit gets quieter. Craving and anticipation get louder. You find yourself thinking about your next drink while you’re still at work. You promise yourself Friday and break the promise on Wednesday.

Here’s the part worth sitting with: this isn’t a moral failure or weak willpower. It’s neuroadaptation — the brain literally rewiring itself so the substance feels necessary and the off-switch feels broken ⁵. NIDA calls addiction a chronic, relapsing brain disorder for exactly this reason ⁷.

Which means if you’ve noticed yourself looping — use, crash, crave, repeat — you’re not imagining it. You’re describing a circuit.

The second map is the one a clinician would use if you walked into an assessment tomorrow. It doesn’t care about your brain circuits or your readiness to change. It counts symptoms.

The DSM-5 lists 11 criteria for a substance use disorder, and the number you meet in the past year tells the story. Meet 2 or 3, and it’s considered mild. Meet 4 or 5, moderate. Meet 6 or more, severe ⁸. There’s no separate diagnosis for “abuse” versus “dependence” anymore — the DSM-5 folded those into one disorder with a severity dial ⁴.

The 11 criteria sort into four buckets, and reading them slowly is its own kind of self-assessment.

• Impaired control covers using more or longer than you meant to, wanting to cut down but not being able to, spending a lot of time getting/using/recovering, and cravings ⁴.
• Social impairment covers failing at work, school, or home; using even when it causes problems with people you love; and giving up activities you used to care about ⁴.
• Risky use covers using in situations that could hurt you — driving, mixing substances, using while caring for kids — and continuing even when you know it’s making a physical or mental health problem worse ⁴.
• Pharmacological signs are tolerance (needing more for the same effect) and withdrawal (feeling sick when you stop or using to head off feeling sick) ⁴.

A few honest notes about this ladder. One, it counts the past 12 months — not your worst year ever. Two, severity can shift. Someone who met six criteria last year and four this year has moved, even if they haven’t quit. Three, the count is a starting point, not a verdict. People with mild SUD can still need real help, and people with severe SUD can still recover.

If you’ve been doing math in your head while reading this, that’s not a bad thing. That’s the map working.

The third map has nothing to do with how much you use or what your brain scan would show. It asks a different question: where is your mind on the idea of changing?

James Prochaska and Carlo DiClemente built this model after watching people quit smoking. They noticed something simple and important — people don’t go from “using” to “quit” in one move. They go through stages, and most of the work happens in your head before anything visible changes.

The five official stages look like this ¹:

1. Precontemplation — you’re not thinking about changing. Maybe the people around you are worried, but you’re not. The problem, if there is one, belongs to someone else.
2. Contemplation — part of you knows. You can list reasons to cut back and reasons to keep going, and the list is roughly tied. You think about quitting on bad mornings and forget about it by lunch.
3. Preparation — something has shifted. You’re making small moves: looking things up at 2 a.m., telling one person, picking a date, pouring out a bottle.
4. Action — you’re doing the thing. Cutting back, abstaining, going to a meeting, starting treatment. This is the visible stage everyone else finally notices.
5. Maintenance — you’ve been at it long enough that the new pattern is becoming the default, though it still takes attention.

Prochaska and DiClemente recognized an unofficial sixth stage too: relapse ¹¹. Not as a failure, but as a normal part of how change actually happens.

The thing to know about this map is that movement is rarely a clean line. People loop back, sit in contemplation for years, jump from preparation to action and back to contemplation, and recycle through the whole sequence more than once ¹. If you’re reading this article at all, you’ve probably left precontemplation. That itself is movement.

Casual use has a quiet quality. You can take it or leave it, you don’t think about it between times, and stopping doesn’t cost you anything.

Use that’s moved past casual sounds different from the inside. It starts asking for attention.

Some signals to read honestly:

• You drink or use more than you planned to, more nights than you planned to, or for longer than you meant.
• You’ve quietly upped the amount because the old amount doesn’t quite land anymore.
• You’ve started timing things around it — leaving events early, planning around the next one, making sure there’s enough in the house.
• You’ve used in situations where it could hurt you or someone else: driving, watching kids, mixing with medication, going to work the next morning underslept.
• You feel rough the morning after in a way that’s becoming familiar — shaky, foggy, anxious, low.
• Someone close to you has said something. Maybe gently. Maybe more than once.

This zone — what clinicians often call risky or at-risk use — is exactly where a brief, structured conversation has the most leverage ¹⁰. You may not meet a full diagnosis yet, and that doesn’t make the pattern fake. It makes it early. Early is good news, because early is where the smallest moves matter the most.

Moderate is the stage most people sit in longer than they admit. On the DSM-5 ladder, it means meeting four or five of the eleven criteria in the past year ⁸. In real life, it looks like this:

You’ve tried to cut back and it didn’t hold. Maybe more than once. You meant to stop at two and didn’t. You picked a quit date and watched it pass.

Use is starting to cost you something real. A missed shift. A fight you can’t quite remember. A project you keep pushing. You’re still functional — that’s part of why this stage hides — but the edges are fraying.

You’ve kept using even when you can see it making something worse: your sleep, your anxiety, your stomach, your marriage, your money.

Cravings show up between uses, not just when you’re around it. You think about it on your commute. You notice every bar sign.

You’ve started hiding amounts — pouring a little extra when no one’s looking, buying at a second store, deleting texts.

If several of these are true at once, you’re not exaggerating. You’re describing a moderate substance use disorder, and it’s the stage where outpatient counseling, intensive outpatient, or a structured program tends to do the most work ².

Severe doesn’t mean you’re a bad person or that you’ve reached some mythical bottom. It means six or more DSM-5 criteria are stacking up in the same year ⁸. The body and the brain are both in it now.

Some of what severe looks like:

Withdrawal is a daily fact. You feel sick — shaky, sweaty, nauseous, anxious, can’t sleep — when you go too long without, and using makes it stop. That morning drink, that first pill, that hit before work isn’t recreational. It’s medicine for a problem the substance itself created ⁵.

Tolerance has climbed somewhere you didn’t expect. The amount that used to feel like a lot is now the amount that gets you steady.

Big parts of your life have narrowed. Friends you used to see, things you used to care about, work you used to take pride in — they’ve quietly stepped aside to make room for use, recovery from use, and planning the next use.

You’ve kept going even when it’s caused serious damage you can name out loud — health scares, lost jobs, relationships ending, legal trouble, near-misses.

Now the third map. Forget how much you use for a minute and answer a different question: what is your mind actually doing about it?

Read these out loud to yourself and notice which one lands closest ¹:

“I don’t really see a problem. Other people are making this into something it isn’t.” That’s precontemplation.

“I can see both sides. Part of me knows. Part of me isn’t ready to do anything about it.” That’s contemplation, and it’s where a lot of honest readers live.

“I’m starting to make small moves. I’m telling someone. I’m looking things up. I’ve picked a date in my head.” That’s preparation.

“I’m doing it. I’ve cut back, I’ve stopped, I’ve walked into a meeting, I’ve called.” That’s action.

“I’ve been at this for a while and I’m protecting what I’ve built.” That’s maintenance.

Here’s what matters: where you sit on this map is not where you sit on the other two. You can have severe SUD and be in contemplation. You can have mild SUD and be in action. The readiness map tells you what kind of next step will actually stick — not whether you need help, but what shape that help should take first ².
