Wanting Outlives Liking, and That's Why Relapse Isn't a Moral Failure

You know the moment. Nothing’s wrong. You’re not sad, not stressed, not even thinking about using — and then a smell, a street corner, a song comes through and your body is already leaning toward it before your brain has said a word. That’s not weakness and it’s not you secretly wanting to relapse. It’s two different systems in your head disagreeing with each other, and this month’s research is finally showing the split clearly.

For decades addiction science and the lived-experience record leaned on one word — craving — like it meant one thing. It doesn’t.

Wanting and liking are not the same system, and the gap between them is where relapse actually lives.

Addiction psychiatrist Mark Gold lays this out plainly: liking is the pleasure you get once you’ve used. Wanting is the pull that makes you go get it in the first place, and it runs almost entirely on a different signal — a molecule called orexin, made in a small part of the brain that normally handles staying alert and motivated to chase things you need, like food. In addiction, that same circuit gets hijacked to treat the drug like a survival need. Gold points out that this is exactly why people who understand the risk better than anyone — physicians who know precisely what an overdose looks like — still develop addictions and still die from them. Knowing isn’t the system that’s broken. Wanting is.

Here’s the part that should actually give you something to hold onto: this circuit looks like it can be turned down. Researchers studying GLP-1 drugs — the Ozempic-family medications everyone knows for weight loss — traced their anti-craving effect to a brain region called the lateral septum, a kind of switchboard that takes “here’s where I am and what happened last time I was here” from memory and pairs it with “is this worth chasing,” then hands that verdict to the brain’s reward system. Loading that region with GLP-1 activity cut cravings for alcohol and, in animal studies, cocaine, opioids, and nicotine too — not by numbing pleasure, but by quieting the switchboard that keeps flagging the drug as urgent.

None of this is a pill you can get prescribed for craving today. But it matters for a simpler reason: it moves the story out of your character and into your biology. The reason you can go months clean, build a life you’re proud of, and still get flattened by a craving on a Tuesday for no reason you can name isn’t that some part of you secretly wants to lose everything. It’s that the part of your brain built to keep you chasing food when you were starving got recruited into chasing something that was never going to feed you, and it doesn’t check in with the part that knows better before it fires.

You’re not fighting a want you chose. You’re outlasting a circuit that hasn’t gotten the memo yet — and every day you don’t act on it, you’re the evidence that outlasting it works.
