CBD Meaning · revised
COA, abbr. Certificate of analysis: an independent lab’s report on one batch.
The numbers on a COA
| Term | Meaning |
|---|---|
| THCA % | The raw acid form of THC in the flower |
| Delta-9 THC % | THC measured by dry weight |
| Total THC % | Delta-9 THC plus 0.877 × THCA, which we work out and show |
| Terpenes % | The compounds that give the flower its smell |
How to check a report
The batch code on the product page should match the code on the report, and the test date should be recent. If either does not match, do not order, and email us the batch code.
Our rule for this shop
The shop lists a flower with its THCA % and total THC from its own lab report. A batch with no lab values on file says so plainly, and we never print a number we have not seen on a report.
