Every product on a licensed dispensary shelf has a paper trail: a Certificate of Analysis (COA) from an independent lab, confirming what is actually in the jar. Most shoppers glance at the THC percentage and move on — but a COA is a genuinely useful document once you know what the other panels mean. Great Smoky Cannabis Co. keeps COAs available for every batch we carry, because informed shoppers make better decisions than shoppers going on label numbers alone.
The six panels worth actually reading
Potency Panel
THC, THCA, CBD, and minor cannabinoid percentages by weight.
Terpene Panel
Individual terpene percentages, when tested — not every lab includes this by default.
Pesticide Panel
Screens for dozens of restricted pesticides, reported as pass/fail against legal limits.
Heavy Metals
Lead, arsenic, cadmium, and mercury — plants readily absorb these from soil and water.
Microbials
Mold, yeast, and bacteria counts, including specific pathogens like E. coli and Salmonella.
Residual Solvents
Relevant for concentrates — confirms extraction solvents were fully purged.
Why potency numbers can vary between labs
It is not unusual for the same strain to test slightly differently at two different labs — testing methodology, equipment calibration, and even which part of a flower sample gets tested can all shift the number by a percentage point or two. A COA is a strong signal, not a promise to the decimal point, and a one-point difference between two similar strains rarely translates into a noticeably different experience.
What actually matters more than the THC number
Pass/fail on contaminant panels matters more than potency. A flower testing at 24% THC that fails a pesticide or microbial screen should never reach a shelf in a properly regulated market — and checking that a product passed every safety panel, not just its potency, is the more meaningful use of a COA for most shoppers.
Ask your budtender, check the product's shelf tag or QR code, or ask to see the full lab report directly — a legitimate product should have a batch-specific COA available on request, not just a generic one for the strain in general.
Batch-specific vs. strain-generic reports
A truly useful COA is tied to the specific batch you are buying, not a general report for “this strain” run at some point in the past. Growing conditions, curing time, and even the specific plant a sample came from can shift results batch to batch — so the most trustworthy dispensaries make batch-level COAs easy to find, not just available if you ask twice.
Ask to see a batch COA before you buy
Every product we sell has an available Certificate of Analysis — our budtenders are glad to walk through one with you.
