The Certificate of Analysis guide.

Every NY-licensed cannabis product has a COA from an independent NY-certified lab. The document tells you potency, terpene profile, and absence of contaminants. Below: how to read it + what actually matters.

Section

What a COA tells you.

Three sections matter: cannabinoid breakdown (THC %, CBD %, CBN, CBG), terpene breakdown (% of each terpene by weight), contaminant testing (pesticides, residual solvents, heavy metals, mold, microbial contaminants — all should pass NY OCM thresholds).

Section

Reading the cannabinoid section.

Listed as % by weight. Total THC = THC + (THCA × 0.877). For flower, the “Total THC” number is what most shoppers care about. Pure THC %is misleading because raw flower contains mostly THCA (acid form) until heated.

Section

Reading the terpene section.

Listed as % by weight. Total terpenes > 2% = noticeably flavorful + characterful flower. Look for the dominant terpene — it predicts the felt effect better than indica/sativa label. Myrcene > 0.5% = body-relaxing. Limonene > 0.3% = uplifting. Pinene > 0.3% = focus. Linalool = calm. Terpinolene > 0.4% = creative.

Section

The contaminant pass.

NY OCM requires testing for residual solvents (relevant for vapes, concentrates, edibles), pesticides, heavy metals, mold, microbial contaminants. All results should be "PASS" or below detectable limit. If anything fails, the product cannot be sold legally — but checking the COA confirms the chain of custody.

Three sections: cannabinoid breakdown (THC + CBD + minor cannabinoids by % weight), terpene breakdown (% of each terpene; total > 2% = flavorful flower), contaminant testing (pesticides, solvents, heavy metals, mold — all should "PASS"). NY OCM requires every product to be tested by a NY-certified lab; the COA proves the chain of custody.

Deeper context

Reading the terpene section.

Listed as % by weight. Total terpenes > 2% = noticeably flavorful + characterful flower. Look for the dominant terpene — it predicts the felt effect better than indica/sativa label. Myrcene > 0.5% = body-relaxing. Limonene > 0.3% = uplifting. Pinene > 0.3% = focus. Linalool = calm. Terpinolene > 0.4% = creative.

Common questions

Common questions.

Why is total THC % different from THC %?
Total THC = THC + (THCA × 0.877). Raw flower contains mostly THCA (acid form) until heated. The conversion factor accounts for the chemical change during decarboxylation. 'Total THC' reflects what you'll actually consume.
What if a COA shows pesticides?
If anything fails NY OCM thresholds, the product cannot be legally sold. Every product on our shelf has passed. We don't stock fail-batch product. If you see a 'pesticide present' note that isn't 'below detectable limit,' ask a budtender to clarify.
Why is total terpene % important?
Total terpenes > 2% by weight signals a noticeably flavorful + characterful flower lot. Below 1% reads as bland, less full-spectrum. Total terpene % is one of the best single predictors of strain quality + experience depth.
