My understanding is that it's always all THCa unless it's been decarbed, AKA burned/cooked, then the A leaves and it becomes THC, the euphoric component.My theory is THCA is grown in a different environment than normal thc and therefore it changes the chemical makeup and removes the psychoactive elements.
As a non-grower (i'm jealous, tho) i have been reading/studying/buying this shit for 7 plus years now and come to pretty much the above conclusion.recent crosses have been crossed over and back so many times chasing yeild, fruity terps, bag appeal.. potency took not only a back seat, but it has to walk while the bus dissapears over the cookie crusted horizon.
I've got a few grams left from my last dispo purchase, and haven't lit a jay in 3 or 4 months, because other than a harsh throat burn, wtf's the point?
