Thinking about this in it's simplest form, decarboxylation turns the THCA into THC through precise heating. If heated too long or at higher temperatures, the THC starts to degrade into CBN. Thinking maybe I can decarb at a higher temp to degrade some of the THC. I have no way of testing or confirming the results other than trial and error.

Just like you, I am a guy who reads so much on the Internet, it gives me a headache. I usually take in all the information and form my own conclusions. It's worked so far.
