Sounds like you are trying to make some Tincture, if that is the case then you need to buy something with a high alcohol content, the higher the alcohol the better extraction you will get. When your mixing the weed and alcohol together make sure you shake it up real good Close the jar tightly and vigorously shake for five minutes then return to the freezer. Continue to agitate the mixture every few hours with refreezing. Continue for a period of two to three days.
Pour the cold mixture through a double thickness of sterile cheesecloth. Save the cheesecloth "ball" for topical uses or use the material to make bud butter once dried. The liquid collected through the cheesecloth should then be filtered twice through a paper coffee filter. Use gloves throughout the process, as it is necessary to squeeze the cheesecloth and coffee filters to facilitate the extraction. Without gloves some of the material will be absorbed on the skin.
If Everclear is used the tincture will be pale green to golden. If 151 rum is used an amber tincture results. Dark green tinctures mean that excess plant material is present. This does not mean that the tincture will not be potent, just taste nasty. When Everclear is used, various flavor extracts may be added (vanilla, raspberry, etc.). Be careful to use only a few drop of flavor extract.
Thats an awesome short-guide man
but actually, it's my buddy who's tryin' to do this, and he doesn't intend on drinking the thc-saturated-alcohol, he's gonna evaporate it (with a hair dryer, or letting it sit) and then take the res and smoke it. Also, he's not using weed, he's usin pipe res... he wants to just throw a pipe in a bag'o'rubbing alcohol.
