Here's something most people don't realize about addiction treatment: few programs in the country prescribe medication at all, and those that do prescribe the same medications, at the same doses to every patient who walks in the door. It doesn't matter that no two people experience this condition the same way. It doesn't matter that your brain chemistry, your metabolism, and your genetic makeup are completely different from the person next to you. The treatment is the same.
When it doesn't work, the system blames you, "You didn't try hard enough." But the truth is, the treatment was never designed for your biology in the first place.
NorthStar takes a fundamentally different approach. Your biology guides your treatment, not the other way around. Genetic testing isn't a bonus feature here. It's a core clinical tool that shapes every medication decision, every nutrient protocol, and every aspect of how your care plan is built, adjusted, and sustained across a full year.
It starts with a simple cheek swab, painless, done at home, included in your treatment kit. Your sample is sent to the lab labeled only with an internal patient ID. No name, no date of birth, no identifying information leaves your home. Privacy is built into the process from the very first step.
What comes back is a detailed picture of your genetics, hundreds of tiny variations in your DNA that, when analyzed together, reveal powerful patterns about how your brain works, how your body processes medications, and where your metabolism may be falling short.
Your care team uses this data in three ways. Select one to see how.
Genetic data helps explain why you developed AUD or SUD in the first place, up to 50% of that risk is written into your DNA, long before any choice you made.
How you metabolize a drug, what dose you need, and which medications will actually work for your biology are all written into your DNA, so we match medication to you on day one.
We find where your nutrient and metabolic pathways need support, then combine your genetic data with lab results to build a protocol specific to your biology.
Why your DNA changes what good treatment looks like, in a few minutes.
One of the most powerful and therapeutic uses of genetic data is helping patients understand why they developed Alcohol Use Disorder or Substance Use Disorder in the first place.
Genetics make the biggest impact on how your body uses nutrients, but they impact medication too. How you metabolize a drug, what dose you need, and which medications will actually work for your biology are all written into your DNA. This is matching medication to your biology, not guessing.
Naltrexone is a clear example. Around 25% of the US population carries OPRM1 variants that make naltrexone significantly less effective.2 Without genetic testing, you'd spend weeks or months on a medication unlikely to work. With it, we know on day one whether naltrexone is the right tool for you.
Another example: if your TPH gene isn't producing enough serotonin, an SSRI alone won't help much. Your genetics tell us we need to support with 5-HTP first, so the SSRI has something to work with. That's how we build a regimen that actually does what it's supposed to do.
Your DNA doesn't determine your character, your motivation, or what you're capable of. What it does is help your care team understand where you need the most support, which tools are most likely to work for you, and how to build a plan that works with your biology instead of against it.
When patients hear their clinician say, "This was not your fault, and now we know exactly how to help you," the relief is something you can see. For many people, it's the first real moment of hope they've felt in a long time.
