ANCHOR is an independent, physician-led national study linking laboratory-verified chemistry to real, anonymous patient outcomes — the first national map of what helps which conditions, at what dose.
For decades, cannabis was sold on folklore and a single number on a label. ANCHOR replaces guesswork with evidence — and stays neutral so the evidence can be trusted.
Founded and directed by a licensed physician — not a marketer, not a retailer.
ANCHOR accepts no cannabis-industry funding. Our neutrality is the asset.
Patients are known only by a self-chosen code name. No identities, ever.
We sell nothing, rank no brands, and point no one toward a purchase.
Every patient rating is matched to that product's Certificate of Analysis — its true cannabinoid and terpene profile. At national scale, patterns emerge that no single clinic, brand, or star-rating app could ever see.
The registry already holds 968,520 lab-tested products from 104 laboratories across 15 states — and it grows every time a patient rates one.
A patient records the product, dose and method, and how it affected their condition — anonymously, in about a minute.
Each rating is linked to the product's lab-verified chemistry — the real cannabinoid and terpene profile behind the label.
At scale, the registry reveals what actually helps which conditions, at what chemistry and dose — and returns it to patients and science.
Dispensary shelves promise 30%+ THC. Across 400,955 lab-tested flowers in the registry, the laboratory record tells a very different story.
median THC in lab-tested flower — not 30%
Reported potency results aggregated from public laboratory and state-registry data; values implausible on their face excluded. Reported, not re-tested.
Every participant gets something back: CODE, the free patient tool that shows your own results — what worked, at what dose, and your closest chemical match when a product you liked is gone. Private, anonymous, and yours.
Explore CODE →Stop guessing. See what actually works for your condition — free, anonymous, built around your own results.
The first national, real-world dataset linking verified chemistry to patient-reported outcomes at scale — built for evidence, not marketing.
Contribute published Certificate-of-Analysis data to independent science. We rank no one and sell nothing — we measure.
"Patients deserve answers built on evidence, not marketing. ANCHOR exists to measure what actually works — and to give that knowledge back to the people using it."
Yes. ANCHOR accepts no cannabis-industry funding and has a written charter to keep it that way. It is funded independently and sells nothing.
Completely. Participants are known only by a self-chosen code name. ANCHOR collects no patient, purchaser, or personally identifying information.
From anonymous patient ratings matched to laboratory-verified Certificates of Analysis, built on a reference base of 968,520 lab-tested products from public and government sources.
No. ANCHOR is a research registry, not a substitute for care from your physician. Participation is for adults 18+ (or the legal age in your state).
