What a COA is and why it exists
A COA is a third-party laboratory test result for a specific batch of cannabis product. NY law requires every batch of cannabis sold at a licensed dispensary to be tested by an OCM-approved laboratory and to meet safety standards before it reaches the dispensary shelf.
The COA verifies:
- Cannabinoid potency (THC%, CBD%, minor cannabinoids)
- Terpene profile (the aromatic compounds that drive much of the effect)
- Pesticide residue (must be below NY action limits)
- Heavy metal content (lead, arsenic, cadmium, mercury — must be below action limits)
- Microbial contamination (yeast, mold, bacteria — must be below action limits)
- Residual solvent (for concentrates only — must be below 500 ppm)
- Moisture and water activity (for flower; out-of-range can indicate mold risk)
How to find the COA for what you bought
Three ways to access the COA for any NY licensed cannabis product:
- QR code on the package. Most NY licensed product packaging has a QR code that links to the COA PDF.
- Brand website batch lookup. Most brands maintain a web portal where you enter the batch number from your package.
- Ask the budtender. At Sage Seeds, we can pull the COA on request for any product on our shelf.
If you cannot find a COA for a product, that is a serious red flag. Every NY-legal product has one.
The cannabinoid section
The most-read section. Look for:
- Total THC (sometimes reported as "Max THC" or "Total THC%"). This is the relevant number for potency. NY licensed flower typically tests 18-30% Total THC. Edibles, vapes, and concentrates report mg per unit or % differently.
- Total CBD. Often near zero in recreational flower. CBD-dominant products report 5-20% CBD.
- THCa. The acidic precursor to THC found in raw flower. THCa converts to THC when heated. Most COAs show both THCa% and Total THC% (which accounts for decarboxylation).
- Minor cannabinoids: CBG (1-2% in some strains), CBN (sleep-associated, often low in fresh flower), CBC, THCV (rare, energizing).
A flower with 22% Total THC + 1.5% CBG is going to feel different from a 22% Total THC + 0% minor cannabinoid flower. Minor cannabinoids matter.
The terpene section
The under-read section. NY licensed flower COAs typically show:
- Total terpene % (1.0% to 3.5% is the common range; higher = more aromatic)
- Dominant terpene (the highest individual terpene)
- Top 3 terpenes with their individual %
For terpene-effect associations, see indica vs sativa vs hybrid. The terpene profile is more predictive of the experience than the indica/sativa label.
The safety section (the most-skipped, most-important)
Look for the words "PASS" in each safety category:
- Pesticides: PASS (or specific compound and ppb if any detected, must be below NY action limit)
- Heavy metals: PASS for lead, arsenic, cadmium, mercury
- Microbials: PASS for total yeast and mold, total coliform, E. coli, Salmonella, Aspergillus
- Mycotoxins: PASS
- Residual solvent (concentrates only): PASS for butane, propane, ethanol, methanol, heptane, hexane, etc.
- Moisture / water activity (flower only): within range
A product that fails any safety test cannot legally be sold in NY. So a NY-licensed product on a NY-licensed dispensary shelf has, by definition, passed all safety tests for its specific batch. The COA proves it.
Red flags
Real things to watch for when reading a COA:
- No COA available. Absolute red flag — do not buy.
- COA from a different state. NY requires NY-licensed lab testing for NY-sold cannabis.
- COA dated more than 12 months ago. Cannabinoids and terpenes degrade over time. Older COAs do not reflect current potency.
- Photocopied or low-resolution COA without lab letterhead. Could be fake.
What a confident COA reader does at our counter
The Sage Seeds customer who reads COAs typically asks for two things:
- Specific terpene profile. "Show me a flower that is high in caryophyllene and low in myrcene."
- Specific minor cannabinoid content. "Show me an edible that has CBN in addition to THC."
Both are legitimate, smart questions. We can answer them by checking COAs on the spot.
