Potency
Potency testing measures how much of each cannabinoid a sample contains. Certificates in this index report it as total THC, total CBD, total cannabinoids, and, for some edible and tablet formats, milligrams of THC per serving. Total THC on a certificate is typically the acid form (THCA) converted to its active form plus any THC already present, computed by the lab from the individual cannabinoid results, not a separate measurement.
of 7143 indexed batches report a total THC percentage
range of reported total THC across every indexed batch
This spans every category on the site at once, from a dosed edible (total THC read as a percentage of package weight, not of a single dose) to a distillate vape. See categories for the range within one category.
batches report THC in milligrams per serving
Printed on certificates for dosed formats (edibles, tablets) alongside the percentage figure.
What a batch page shows
Every batch page on this site republishes whichever potency totals its certificate printed: total THC, total CBD, total cannabinoids, and THC per serving where applicable. A field the certificate did not print is left off the page rather than shown as zero. Some batches also carry a full cannabinoids panel, itemizing each individual cannabinoid rather than only the totals; see the full-spectrum leaderboard for which brands' certificates carry that panel.
Result vocabulary
An individual cannabinoid on a full panel is reported using the same five-outcome vocabulary as every other analyte on this site. See what these mean.
