There’s no burning. It does vaporize most of the oils, but unless you smoke it way down/have a super efficient rig like myfriend, there’s usually about the same amount left as you’ll find on sugar leaf trim. So you’d need maybe a 4x the amt of already vaped buds as you would unvaped buds. That’s in my personal experience.
I don’t discard, I eat the vaped flower. Just as the vaped buzz wears off, the slight edible buzz kicks in. When you vaporize it decarbs it. @boomer I have the model you’re questioning. Vicod 5g It’s a good quality unit that functions very well. I use the straw, as it stays a little cooler. I also vape for about 10 minutes (2 cycles) for the best effects. Then consume the vaped flower as mentioned above. ^ This unit uses convection, meaning no flower is being wasted. It heats the incoming air before it hits the flower. So more terpenes and flavors come out. I start at 300° and work my way up to 400°.
