Understanding Certificates of Analysis (COAs)

Posted: 11-18-2024

Written By: Kelsey

Knowing how to read a cannabis COA helps you make informed choices about safe, quality products, and here at Evolution Health and Wellness, we believe knowledge is power! Cannabis is an agricultural product, and thorough COA testing for contaminants and potency ensures consistent safety and quality.



What is a COA?

A Certificate of Analysis (COA) is a lab-generated report that verifies a product’s safety and potency, testing for key compounds like cannabinoids and any potential contaminants. COAs help consumers understand the purity and quality of their products.



Why COAs Matter

Product testing is crucial for consumer safety. While cannabis isn’t FDA-regulated, COAs ensure harmful substances—like pesticides, heavy metals, and microbes—are screened out. Brands committed to transparency provide COAs to show exactly what’s in their products, giving you confidence in each purchase.



What You’ll Find on a COA

  • Cannabinoid Profile: Displays THC, CBD, and minor cannabinoids for potency and effects.

  • Contaminant Testing: Screens for microbes, pesticides, heavy metals, and solvents.

  • Terpenes: Highlights aromatic compounds that may influence the product’s effects.


Understanding these components can help you find products that suit your preferences and health needs.



Where to Find a COA

COAs are often linked via QR codes on product packaging or the brand’s website. Our knowledgeable staff is always ready to help interpret COA information, so feel free to ask any questions when you shop with us!
