Hey you should post this over on Smoke.io if you havn't already. At first I was wondering about smoking leaves such as fan leaves which I think have almost no thc but after reading it like you said its the little leaves that shootdirectly off the buds that are taken off during trimming. those leaves typically do have a lot of crystals on them. a lot of times they use that for edibles or bubble hash but thats interesting you can smoke them as well.
