Here's something I found on this:

Cannabis vodka

Ingredients:


1/4 oz. of stockpiled cannabis stems from breaking up buds.
Vodka (any kind should do)
Glass container

Place all stockpiled stems in a jar. Pour in your vodka, just enough to fully submerge the stems. Let set in a dark place for about a week. After that, you will need to strain out the stems. A great trick is to make tea type bags out of coffee filters and stems for easy removal.

Why this works: Stems contain a small amout of THC, but not really enough to be worth smoking. Compiling enough stems together and soaking them in vodka releases the THC into the vodka without messing with the nasty smoke. This is great because most people throw their stems away anyway.
