should be able to make a semi-oil..
i saved roach papers for a while when i was younger, and tried to make oil with them. should be similar to that, as they're both just resins. *i don't know if it extracted thc, or just boiled the resins though, thinking it was probably the same as smoking resin streight.
was kinda weird.. was more like hash, as it was very solid. but once hot, melted and acted like oil.
wasn't the greatest, but it worked when i was out.
but i'd say don't bother unless you're right out and hurting for a hoot.
