Research we ran ourselves
Questions nobody in this industry had published a straight answer to. They came back against what the category assumes, and they are why this site works the way it does.
4,914 samples · 1,950 growers
A strain name does not predict its chemistry
The highest terpene changes between growers for every one of 18 cultivars we tested.
651 certificates · 12 libraries · 16 panels run
Effectively nobody in this channel publishes terpene panels
One certificate in 651 reported terpene figures — and at least six laboratories either run the assay or print it as an option nobody ticks.
0.4 mg per container · 12 November 2026
What changes for hemp shops on 12 November 2026
The federal definition of hemp changes: total THC starts counting THCA, and finished products are capped at 0.4 mg per container. What survives, and where four states already differ.
