No. Terpenes are the flavors and smells and delivery systems for the cannabinoids. The variation in terpene profile can determine the effect. But not the cannabinoid % you can have 2 strains with the exact same cannabinoid profile but different terpene profile and have a different high from each
The cannabinoid profile is the amount of thc, cbd. cbn, cbg, cbc, thca, thcv
During curing or decarboxylation, thca converts to thc. Then as thc degrades turns into cbn
The higher the brix level in a plant the higher the terpene profile.
