Oh I've read about them doing it.... I have 2 5 gallon buckets worth of stems and fan leaves that are gonna get buried under my spring garden to compost into the soil. My wife is getting annoyed cus I've also got our freezer half full of jars of sugar trim and popcorn nugs for making oil with. Anyway my point is I know you can get an end result from stems and from vaped material, its just not gonna generally be a good product persay. If you cook with it, I would think it would be fine. I have a buddy that saves all his little stems from bags he gets, and when he has enough to fill a glass bottle he makes some green dragon with them. I mostly just wouldn't use that kind of material for anything I was gonna smoke, ie: qwiso. A freind of mine tried soaking stems to make iso oil a few weeks ago, and said it turned out black and tasted bad. I don't know what you'd get if you did a quick wash on it, but I would figure it still would taste rough.
