Flower testing
Potency, terps, pesticides, microbials.
Every jar of flower gets tested for cannabinoid content, full terpene profile, pesticide residues, and microbial contaminants before it hits our shelf.
Leafology Cannabis Company at 244 Main Street, Suite 1, White Plains, NY 10601 sells exclusively third-party lab-tested cannabis products as a licensed adult-use dispensary regulated by the New York Office of Cannabis Management. Every flower, concentrate, edible, tincture, topical, and pre-roll on the shelf has been independently tested by a New York State licensed, ISO 17025-accredited laboratory for cannabinoid potency, terpene profile, pesticides, heavy metals, microbial contaminants, residual solvents, and mycotoxins.
What we test for
Six panels, zero guessing.
New York requires every product sold at a licensed dispensary to pass a comprehensive testing regimen. Supplier COAs cover cannabinoid and terpene potency, pesticides, heavy metals (arsenic, cadmium, lead, mercury), microbial contaminants (E. coli, Salmonella, Aspergillus), residual solvents, and mycotoxins.
If a batch fails any panel, it cannot legally be sold - and it isn't. Ask any budtender to pull up a product's COA any time.

What is a Certificate of Analysis (COA)?
A Certificate of Analysis is a lab report issued by an ISO 17025-accredited cannabis testing laboratory. It documents cannabinoid potency, terpene profile, and pass/fail results for pesticides, heavy metals, microbial contaminants, mycotoxins, and residual solvents for a specific production batch of cannabis.

What is third-party lab testing for cannabis?
Third-party lab testing means an independent laboratory -- not the cultivator or dispensary -- analyzes cannabis products for potency, contaminants, and safety. New York requires all licensed cannabis products to pass third-party lab testing before sale.What do cannabis labs test for?
Licensed labs test for cannabinoid potency (THC, CBD, CBN, CBG), terpene profiles, pesticides, heavy metals (lead, mercury, arsenic, cadmium), microbial contaminants (mold, bacteria, yeast), residual solvents, mycotoxins, and moisture content.What is a Certificate of Analysis (COA)?
A Certificate of Analysis is a lab report documenting the test results for a specific batch of cannabis. It lists cannabinoid percentages, terpene profiles, and pass/fail results for contaminants. COAs are the gold standard for cannabis transparency.Can I see lab results for products at Leafology?
Yes. Leafology provides Certificates of Analysis for any product on request. Ask your budtender in-store, or contact us for digital COA access.Why does lab testing matter?
Lab testing protects consumers from pesticides, heavy metals, mold, and inaccurate potency labels. Without testing, there is no way to verify what is actually in a cannabis product. Licensed dispensaries like Leafology only sell products that have passed all required tests.Are concentrates and edibles also lab tested?
Yes. All product categories sold at licensed dispensaries -- flower, concentrates, edibles, tinctures, topicals, and pre-rolls -- must pass the same third-party lab testing requirements before reaching the shelf.How often are products tested?
Every production batch is tested before it can be sold. This means even the same strain or product may have different COA results between batches, reflecting natural variation in cannabinoid and terpene content.
