Well I know that cannabinoids do vaporize but some require a higher temperature than THC does. And your right that the cbn's and cbd's play a huge part in the medical use of cannabis like for pain relief. That's why some of us run our temps up while vaporizing. I read a article where aids patients smoked the duff from vaporizers in the middle of the night to release the unvaped cannabinoids. They used it for a sleep aid. There even was a cute term they used to describe the action but I can't remember it.
I'll see if I can find that article for you.
