The average cultivar now peaks at 20.4% THC.

The THC Potency Index reads the chemistry of 170 indexed cultivars — not marketing labels, but the maximum reported THC across breeder and lab data in the network.

Methodology

— Source: the network cultivar index behind WeedYouLike — breeder-reported and lab-observed chemistry for every indexed cultivar.

— We use maximum reported THC per cultivar; the average is the arithmetic mean across all cultivars with valid chemistry data.

— Potency is chemistry, not effect: dose, tolerance and terpene profile change the experience as much as the number.

— The index grows as the network grows; figures recompute on every request.
