Yep, butane extraction produces what is commonly called honey oil.
I have, after years of trying to come up with some palateable (sp?) way to smoke the resin, come to the conclusion that including it in with the leaf matter when doing a butane extraction is about the only way. Its kind of labor intensive because it needs to be powder dry, but i hate the idea of wasting that thc. Unfortunely I hate smoking it in the conventional way even more.

edited to add that the resin I use comes from the stem of my bong and the plant matter that gets pulled through into the water.
Shes right THC is not water soluble.
