What Are Terpenes?
Terpenes are organic compounds produced by hemp and cannabis plants (and many other plants) that create distinctive aromas and flavors. Beyond smell, terpenes work synergistically with cannabinoids like THCA and CBD in what researchers call the "entourage effect" — meaning the combination of compounds creates a different experience than any single compound alone.
When reading a COA (Certificate of Analysis) for a THCA product, the terpene profile section shows which terpenes are present and at what percentage. Higher-quality flower and concentrates typically carry a more robust terpene profile.
