In this thread, someone posted info about using glycerine as the solvent to disolve THC from buds:
Healthier Cannabis Food
It sounded like the advantage was that you could put the drops under your tongue. It said that glycerine will enter your system from under your tongue, while other kinds of tinctures based on alcohol won't. It said that the high comes on faster than other methods of ingestion.
Has anyone ever tried to use glycerine? How did it work? How did you do it?
BTW, I checked around on other forums and one had this same recipe. People there decided that the second method described in the post was probably not accurate, becasue no one was able to find the equipment specified, specifically the "pharmaceutical grade boling beaker with threadlock top." They decided that whole high temperature boiling beaker method thing was bunk and maybe dangerous, but some of them tried the warm-and-shake method of extraction. So I'm wondering if anyone here has tried that.
