Terpenes, plainly
Terpenes are aroma compounds that help describe product chemistry.
In cannabis, terpenes are part of the lab-reported chemistry profile alongside cannabinoids like THC and CBD. They can help explain why two products with similar THC numbers may smell, taste, or be described differently.
Terpene profiles are not fixed promises. Product chemistry can shift by grow, extraction method, package age, storage, and batch. The useful question is not just which terpene is present, but how often it appears, how much was detected, and which compounds show up with it.
