Lab Testing, Quality & Product Data
Certificate of Analysis (COA)
A Certificate of Analysis (COA) is a lab report that shows what is in a cannabis product and confirms it has been tested for potency and safety.
What a Certificate of Analysis Is
A Certificate of Analysis, commonly called a COA, is an official document produced by a third-party laboratory after testing a cannabis product. The COA provides verified data about the product’s chemical composition, including cannabinoid levels and the presence or absence of contaminants. It serves as a transparency tool that allows consumers, regulators, and businesses to understand exactly what a product contains.
How COAs Report Potency
One of the primary purposes of a COA is to report potency. This includes the measured amounts of cannabinoids such as THC and CBD, often broken down into total and active forms. Accurate potency information helps consumers dose responsibly and allows manufacturers to label products correctly.
How COAs Protect Consumer Safety
COAs also play a critical role in consumer safety by documenting contaminant testing. Many COAs include results for pesticides, heavy metals, residual solvents, mold, and microbial contamination. These tests help ensure that cannabis products meet safety standards and do not pose unnecessary health risks when consumed.
Why COAs Are Required in Regulated Markets
In regulated cannabis markets, COAs are often legally required before products can be sold. They support compliance with testing regulations and provide accountability throughout the supply chain. Many products include a QR code or batch number that links directly to the COA, allowing consumers to review lab results before or after purchase.
How COAs Build Consumer Trust
Beyond compliance, COAs help build trust. Transparent lab reporting allows consumers to compare products, verify claims, and make informed choices based on potency and purity rather than marketing alone. For medical users in particular, COAs are essential for consistency and predictable effects.
The Role of COAs in Cannabis Education
In cannabis education, the Certificate of Analysis is considered a cornerstone of responsible production and informed consumption. Understanding how to read and interpret a COA empowers consumers to prioritize safety, accuracy, and quality when selecting cannabis products.
