What is a certificate of analysis, or COA?

A COA is a laboratory report for a tested sample associated with a product batch. It records results and identifying information. Match it to the actual package; a report for another batch does not describe the product in your hand.

Do all cannabis products have identical testing panels?

No. New York’s testing requirements depend on the product and matrix. OCM’s February 2026 FAQ, for example, distinguishes residual-solvent testing for ordinary flower from relevant solvent-based or infused products. Use current OCM guidance and the applicable product report.

Does a passing report mean cannabis is risk-free?

No. A report records results for the tested sample and applicable criteria. It is not a guarantee against impairment, an individual adverse response, later damage or a later product notice. Follow the current label and consumer guidance.

Can Leafology help me find a COA?

Contact the store with the exact product name, producer and batch identifier, or ask staff while viewing the package. The correct report matters more than finding any report with a similar name. This guide does not promise immediate access to every historical document.

Is a test date the same as a package expiration date?

No. Sample, testing and report dates describe laboratory events. The product’s labeled expiration or storage instructions are separate. A recent-looking date alone does not establish the current condition of the item.

Where do I check New York recalls and product notices?

Use OCM’s current administrative orders and recall notices. Match the exact brand, product and batch information in the notice. Follow the notice’s directions and contact the store if you need help identifying your product.

What a report tells you

One product. One matching record.

A COA ties laboratory results to identifying information about a sample and batch. Begin with the package, then compare the report. A report for a different size, product or batch needs clarification even when the cultivar name looks familiar.

Read the units carefully: percentages, milligrams per gram, and amounts per serving or container describe different quantities. A cannabinoid number alone does not predict an individual experience.

Reading a COA

Four checks before drawing a conclusion.

1
Start with the package
Find the product name, producer and batch or lot identifier. Keep the package available while reviewing the report.
2
Open the product’s report
Use its QR or barcode link where provided. If the link is unavailable, ask the store or producer for help finding the report for that product.
3
Match the identifiers
Compare the product and batch information on the package with the report. A familiar cultivar name alone does not establish a match.
4
Read the results and notes
Check the lab, dates, units, applicable tests and any qualifications. Ask about a missing or unclear result before drawing a conclusion.

Product-specific testing

The required tests can differ.

OCM’s testing FAQ distinguishes ordinary flower, infused products and extracts. It also distinguishes measured results that are report-only from results assessed against particular limits. A single universal six-panel checklist does not accurately describe every product.

Check the current requirements

The current package

Keep the report in context.

Read the full report, including its notes and product identifiers. If a result is unclear, ask the producer, laboratory or store for clarification. A blank field or unfamiliar abbreviation is not a reason to invent a pass or fail result.

Ask Leafology for help

Missing link or mismatched batch?

Keep the product label, package and receipt. Send the store the product name and batch details, and explain which report you found or which link failed. Staff can use those details to help locate or clarify the record.

Check current notices

A historical laboratory report does not replace a current recall or administrative notice. Check the official notice for the affected product and batch, and follow its instructions.
