Mine didn't taste like it had any residue in it, evaporated just like a spice extraction (naphtha) and I smoke it more frequently than eat oil. All I know is it was stronger than I anticipated. I'm guessing it's already decarbed in the RSO method. Still gonna try the ethanol anyways just to try it.

Plus I think I was going to make a tincture, just leave it in ethanol, should stay thinned out enough for that.
