if it was exposed to that heat and that time, it's probably decarbed... 72h is likely beyond enough time for 140F, so decarb is inevitable (230f and 45mins does it, and lower heat will just take longer.. 140f is stil hot enough to accomplish the task, if i recall). Which means the decarbed thc will deteriorate much faster than non-decarbed flower. Also, evaporating off all the more volatile compounds, which may or may not be intentional? All the stuff with a low enough boiling point will be gone - inclduing more than a few types of terpenes and cannibinoids.
unfortunately, i think the character limit here is a problem... more things would need to be explained as to why. also, not really a question, lol. could just put this in your diary. this is more of an advertisement.
