The most lab-tested cannabis brands in California and New York

The short answer

In California, Heavy Hitters leads with 613 results (none failed), ahead of Almora Farm with 365. In New York, Ayrloom leads with 1,821 results (none failed), ahead of Heavy Hitters with 687. These counts are compliance certificates this index holds and links to the issuing lab, so they measure how much of a brand's testing is on public record, not how much it sells. More results mean more evidence: a brand with hundreds of results on file has shown its consistency in a way a brand with five cannot.

How we counted

A result counts when the certificate prints a compliance verdict, pass or fail; R&D and informational panels are left out. The count reflects what this index holds, which grows as labs, brands and retailers share certificates, so a brand ranking low here may simply be less indexed. For how often brands fail, see brands that have never failed a lab test.
