Hopefully this is interesting and perhaps useful to add to the forum.
Many posts on here worry about overcooking Cannabis-oil thinking that a significant portion of THC oxidizes to CBN.
THC actually seems to me to be a fairly robust compound, from some testing results that I've obtained recently.
Recently I had been able to obtain some decent, mid-grade indica at a reasonable price, and then extracted the Cannabis-oil into a concentrate to use for oil dabs, in edibles, etc.
Once the extract was purged, I heated it in an 'double-bath' arrangement in a fondue cooker to precisely control the heat applied in a narrow range of 4°-5°C, for an extended period of time. I used a digital thermometer inserted into the oil-bath to monitor the temperature fairly precisely, and in a controlled manner.
Here are the test results from a certified test lab (in Washington State) for decarbing for 8 hours at 122°C (248°F).
CANNABINOID PRE-decarb POST-decarb %CHANGE
THC 71.91% 79.15% +7.24%
CBN 0.69% 1.09% +0.50%
CBC 0.88% 1.02% +0.16%
CBG 1.51% 1.96% +0.45%
THCV 0.37% 0.36% -0.01%
Very Interesting results after 8 hours of cooking —> THC and other active cannabinoids have increased during the extended heating cycle.
=>> THC has increased significantly during the process, while at the same time CBN barely crept up, so fears here appear to be overblown.
