Massachusetts cannabis lab results, on every product.
Massachusetts tracks every licensed cannabis package from harvest to sale in METRC. We show that lab test record on each product page, so you can see what was tested before you order delivery.
Why we show it
A potency number is only useful if it belongs to the batch you're buying, and cannabis changes from harvest to harvest. So each listing is matched to the METRC package we actually have on our sales floor, and the lab panel shows that package's record.
Licensed cannabis in Massachusetts is tested by an independent, state-licensed lab before it can be sold (935 CMR 500.160). Those results are entered against the package tag in METRC. Our site reads them and refreshes regularly, so a new batch brings its own numbers with it.
We don't interpret results into promises. Numbers describe the tested sample. They aren't a measure of quality and they don't predict effects, which vary from person to person.
How to read the lab panel
- Package tag
- The 24-character METRC tag assigned to one specific package. It's the key that ties the listing to the state record. The same product name can have many tags over time, one per package.
- Harvest batch
- The harvest or production batch the package came from, as recorded by the cultivator or manufacturer.
- Testing lab and test date
- The independent lab that tested the batch and the date the result was recorded. Newer isn't better or worse; it just tells you which test you're looking at.
- THC, CBD and total cannabinoids
- Measured percentages by weight for the tested sample. They describe the package, not how it will feel: people report very different experiences from products with similar numbers.
- Terpenes
- Aromatic compounds behind the smell people commonly describe as citrus, pine, pepper or earth. They appear only when the lab reports them.
- Contaminant screening
- Contaminant screens such as pesticides, heavy metals, microbials, mycotoxins and residual solvents. We show each result as passed, failed or not reported. Under 935 CMR 500.160, a product that fails required testing can't be sold unless it is remediated and passes a retest.
- Where it's been
- Chain-of-custody steps from the state record, such as harvest, packaging, lab testing and arrival on our sales floor, oldest first.
The two labels you'll see
- ● Verified
The panel shows the METRC record for the package in stock, with the time we last synced it.
- Sample data
The listing isn't connected to its package yet. Values are placeholders, not a test result, and will be replaced once the record syncs.
A note on edibles and tinctures
Start low, go slow. The impairment effects of edibles and swallowed tinctures may be delayed by two hours or more and can last several hours. Wait before taking more, and don't drive after consuming cannabis. The dose on the package label is the number to plan around.

Lab result questions
What is METRC?
METRC is the seed-to-sale tracking system Massachusetts uses for licensed cannabis. Every plant and package gets a unique tag, and licensees record harvests, transfers, lab tests and sales against it.
Are these lab results for the exact product I receive?
They're for the package we have in stock and matched to the listing. When a batch sells through and a new package goes on the shelf, the listing updates to the new package's record.
What does 'Sample data' mean on a product page?
It means we haven't finished connecting that listing to its METRC package, so the lab panel shows placeholder values. Sample data is never a real test result, and it's always labeled.
Is higher THC better?
Not necessarily. Potency is one measurement of the tested sample. It doesn't tell you about quality, and it doesn't predict how a product will feel. If you're new, choose a lower-potency product and start low, go slow.
Where can I see the full certificate of analysis?
When the testing lab provides a certificate of analysis (COA), the lab panel links to it. If there's no link yet, the panel says so.
