What is a COA?
- A Certificate of Analysis is a document from an accredited independent laboratory
- It confirms the composition and quality of a specific batch of medical cannabis
- It is a cornerstone of EU-GMP quality framework and pharmaceutical supply chain transparency
- Every patient should ask for — and receive — a COA for their prescription product
A COA is your quality guarantee. It tells you exactly what is in your medication and confirms it is free from harmful contaminants.
