well i was wondering this as well, becasue i read some thing on how to do this for weed brownies. I ended up wasting 6 grams of bud casue it didnt work for one reason or another...

but the method i tried was double boil method, where you got one big pan full of water to a boil, and a smaller one with teh oil n ground up bud in it sautee'ing. Can someone specify, becasue i ended up using sunflower oil, the 2nd pan dindt seem to be too hot looking at it(ie, no bubbling or nething) but the pan itself was pretty hto
