Why THC % often overstates felt potency

Two flowers labeled 22% THC can feel completely different. Terpenes, freshness, and cure matter more than the headline number.

The headline number

Dispensaries put THC % on every label because customers ask for it. But THC alone is a poor predictor of how strong something will feel.

What actually drives potency

  • Terpene profile — myrcene increases the body-heavy effect; limonene amplifies the head feel.
  • Freshness — degraded flower oxidizes THC into CBN. Felt potency drops.
  • Cure — properly cured flower releases more terpenes; rushed cures feel harsh and hit thinner.
  • Format — vaped vs combusted vs eaten changes the curve dramatically.

A better question for the budtender

"What's the dominant terpene?" — beats "what's the highest THC?"
