The number on the front of the jar is not the whole story.

What THC% actually measures

It's the percentage of THC by weight in the dried flower — usually 18–30% for indoor. Higher does not automatically mean better.

What actually predicts the experience

Terpene profile — the aromatic compounds that shape the effect
Cultivation quality — how the flower was grown, dried, and cured
Freshness — old flower loses terpenes fast
Your tolerance and setting

Read the COA

Every product at a licensed NY dispensary comes with a Certificate of Analysis. Look at the full cannabinoid and terpene panel — not just the headline THC number.
