Connecticut publishes every cannabis product registered for sale, together with
a link to the laboratory certificate of analysis, the COA, behind it. Those COAs are PDFs,
one per product, tens of thousands of them. This site reads the numbers out of them so you
can sort and compare in seconds, then hands you straight back to the original document.
The seven buttons
- Yeast & Mold
- Ranks every product in the period you have loaded by its total yeast and mold count, highest first,
in colony-forming units per gram (CFU/g). This is the panel most people come looking for.
- Aerobic Bacteria
- The same ranking for total aerobic bacteria, against Connecticut's 100,000 CFU/g rule.
- Heavy Metals
- Ranks by each product's single highest metal reading, arsenic, cadmium, lead, mercury or
chromium, all converted to one unit (µg/kg) so they can share a list. The chips on each
row show the other metals from that same COA.
- Pathogens & Limits
- Every result this site covers where a measurement passed the limit printed on its own
certificate. It ignores the period above, because findings this rare cannot be ranked
inside a 30-day window. A pathogen is only listed here when it has been confirmed by
re-reading the laboratory's own PDF, never on the strength of a status word alone.
- Duplicate COAs
- Finds one lab report PDF that several different registered products all point at, and
groups them so you can open the report and see what it actually covers.
- Re-Test / Multiple COA
- Products whose certificate holds more than one laboratory sample, an initial test and a
later re-test printed in the same PDF. Every sample is listed with its date and the
verdict the laboratory printed for it, oldest first, so a result is never read without
the result that superseded it.
- All Products
- Everything added to the state registry in that period, with no laboratory filter at all.
Choosing the period
Pick how much time, 30 days, 90 days, 6 months or a full year, then the date it
ends on. The arrows step the whole period backwards and forwards, and the range is
always spelled out underneath, so you are never guessing what you are looking at.
A full year is about 800 KB, which is a second or two on a phone. It is also what makes the
search box most useful, since search only ever looks at the period you have loaded.
Under Jump to a specific month or date you can go straight to any month this site
covers, return to today, or jump to the newest period whose COAs have been read.
Coverage starts at January 2021. Connecticut's registry does run further back, but
the older records are mostly scanned certificates whose numbers cannot be read reliably, so
ranking them would mean ranking gaps. The period controls stop at the start of 2021 for that
reason, not because nothing was registered earlier.
Reading a result
- The big number is the measurement and its unit, followed by the limit it is being
judged against.
- The colored pill turns that into a percentage of the limit, so you can scan a list
without doing arithmetic.
- The product name and the ↓ COA (PDF) button both fetch the same lab
report.
- ↓ Photo and ↓ Label fetch the product photograph and the packaging label
the producer filed with the state. They are links rather than pictures on the page because
the state serves the originals, which average half a megabyte and sometimes exceed two, a page of them would cost tens of megabytes on a phone.
- Everything with a ↓ downloads a file. The state's site sends these documents as
attachments instead of displaying them, so each arrives in your downloads folder named
PublicDocument.pdf or PublicDocument.jpg. That is how
elicense.ct.gov behaves and no website linking to it can change that. Nothing downloads
unless you tap one of those buttons.
- The small picture at the left of a row shows the product type: flower, pre-roll,
vape, edible, concentrate, tincture, capsule or topical. If the state ever files a dosage
form that matches none of those, the row simply shows no badge rather than a wrong one.
- The green line is who made it and the date it was registered.
- The small gray line is the product type, the testing laboratory, and the state
registration number (the MMBR number) if you want to look it up yourself.
- The chips underneath show other panels from the same COA, aerobic bacteria,
mycotoxins, metals. A red chip is a reading above its stated limit.
What the colors mean
Each pill compares the reading to the limit that applied on that product's test date,
not today's limit. Connecticut's yeast and mold standard has been 10,000 CFU/g, then
1,000,000 for one laboratory during a two-year window, then 100,000 since mid-2022, so an
older result is judged by the rule it was actually tested under.
- Under 25% comfortably inside the limit
- 25–50% inside the limit
- 50–75% inside the limit, worth noting
- 75–100% close to the limit
- Over the Limit above the limit printed on its own COA
- Below Detection the lab reported “less than” its
measurable floor, a ceiling, not a measurement
A reading in the top band also carries a small hazard picture beside it. It appears only at
75% of the limit and above, and it is a prompt to open the COA, not a safety warning: a
result at 90% of its limit still passed the limit.
Four things that will mislead you if you skip them
- “Below Detection” is not a number
- A COA printing
<100 means the result was under the instrument's floor, not
that it was 100. Those rows are labeled and kept out of the rankings, because otherwise a
product that was never quantified would outrank one that genuinely measured low. Tick the
box under Narrow It Down to see them anyway.
- Not being on the list is not a clean result
- A product can be missing from a ranking for two very different reasons, and the summary
distinguishes them. Some COAs genuinely carry no panel for what is being ranked. Others
carry it, but the automated reader could not pull the number off that laboratory's page
layout, for one laboratory this currently affects several hundred products a year whose
certificates plainly show the test. Neither means a product went untested. Open the
COA and read the laboratory's own document.
- A duplicate COA is not an accusation
- One laboratory report covering several products is a documented report layout, commonly
used when a producer tests a batch that becomes several SKUs. It is surfaced so a person can
look, not because it is evidence of anything.
- One certificate can hold more than one test
- Some COAs run to a dozen pages and contain two different samples: a first test and a
later re-test of the same product, with different results. Reading only the first one can
tell you the opposite of what the document as a whole says. Where this site has found a
certificate like that it lists every sample under Re-Test / Multiple COA, and the
most recent sample is the one the product shipped on.
Why some periods have no numbers
The product registry is read live from the state and is current to within a day or two. The
laboratory panels are read out of the COA PDFs in advance, which lags behind. So the newest
few weeks usually list every product with a working COA link but no ranked numbers yet. The
site says so when that happens and offers to move you to the newest period that does have
them. The footer always states the exact coverage date.
Keeping it on your phone
Added to your home screen it behaves like an app: its own icon, no browser address bar,
and it opens straight on the last 30 days.
- iPhone and iPad
- Open the site in Safari (this does not work from Chrome on iOS). Tap the
Share button: the square with the arrow, scroll down, tap
Add to Home Screen, then Add.
- Android
- Open the site in Chrome, tap the ⋮ menu, then Add to Home screen
or Install app, and confirm.
- Desktop
- In Chrome or Edge, an install icon appears at the right-hand end of the address bar;
it then opens in its own window. Safari on a Mac uses File → Add to Dock.
It still needs a connection, this is a shortcut to the live site, not an offline copy,
so the registry stays current every time you open it. Nothing is stored on your phone
beyond the icon and your own preferences, such as the theme you picked.
Getting more out of it
- Search matches producers, products, brands and registration numbers. Type
Theraplant, Curaleaf, Crisp, a strain, or an MMBR number.
- Narrow It Down filters to one producer or product type and changes the sort order.
The summary tiles re-scope to whatever you filtered to.
- Download This List (CSV) gives you exactly what is on screen, at full precision,
with the COA link on every row, ready for a spreadsheet.
- Copy Link to This View puts the period, the view and your filters in the URL, so
you can send someone the exact screen you are looking at.
- Verify before you repeat anything. Open the COA. The PDF is the record; this site
is only an index to it.
