Heh... well, I know that wasn't the problem. I used a just under a half ounce. And I took all the capsules I got from that except two. Something had to have been wrong with the process of getting the THC out of the plant. It did not turn brown or get overheated, either. I'm open to ideas, of course. I admit I had a lot of fun. The whole process reminded me of compounding in pharmacy school.
