This procedure will separate codeine, hydrocodone, or oxycodone from aspirin, APAP (acetominaphen, paracetamol), or ibuprofen, but it won't remove caffeine. Be a good cook and read the whole recipe before beginning the process.
Crush the pills up up very thoroughly. You can use a sturdy pill or vitamin bottle and a ramekin for this. If you're extracting 10 pills, a quarter cup of water is more than enough (50 ml if you have a measuring cup with mls on it is good). With 15-20 Vicodin ES, 100 ml of water works well. The more water you use, the more you will end up having to take and the more difficult it is to get the bad stuff out, so don't use too much. Conversely, too little water will give you just a paste that can't be separated. If you're going to extract more than one dose, then measure it in some way. You can, for instance, do up four or ten doses, just use some measure, like an empty eye-drops or herbal extract bottle.
Dissolve the crushed pills in the water; stir or shake till all the clumps are gone. Pour into the bottom of a small bowl, cover, and put it in the freezer. Let it get really cold, but not so cold it freezes (some binders seem to get really swollen if they freeze). This shouldn't take that long, since it's shallow. You will see the APAP actually crystallize out and you will be able to feel it as grit when you stick your finger into the liquid above the sludge and then rub your fingers. (But even if it doesn't do that, it works anyhow! Read the info about how it works to see why.) Take the liquid out of the fridge.
For a filter, use a piece of cloth about the size of a washcloth. The cloth can be any closely-woven cotten, preferably undyed. The back of a dress shirt or a piece of plain muslin works well. Tshirts are usually too loosely woven to work. Soak the cloth in cold water while you are waiting for the APAP crystals to form. Put the cloth in a coffee filter cone or just drape over the edges of a small bowl, glass, or jar. When the solution is ready, pour everything, solution and glop, into the cloth. Bring up the ends of the cloth and squeeze the solution through. This will produce a fairly cloudy solution. Now filter that cloudy solution through a coffee filter that has first been wet down with ice water. While that is filtering, scrape the glop left on the cloth into the bowl and add another 50-100 ml of water to go through the whole process above again and get more good stuff out of the glop. When the solution in the freezer is ready, pour it through the cloth, squeeze out, and filter that through a coffee filter wet down with ice water, just as you did the first batch. Add the two more or less clear solutions together.
If you want even purer stuff with less APAP, first reduce the volume of water by evaporating some of it in a warm oven or with a hair dryer. Take a couple of APAP crystals from your sludge, put them in the liquid to seed further crystallization of APAP, and repeat the chilling and filtering process.
You can drink your solution. Remember if you have made up more than one dose at a time to split it up before drinking it. Also, take it on an empty stomach for max absorption, or see the section on Potentiation to really increase the effectiveness of the opiate. Opiates are very terrible [in fact, one person reported continuing the extraction until the water was no longer bitter as a way to get out every mg of opiate]. You can eat a piece of chocolate or a cracker spread with butter first to kill the taste (and the fat will help the narcotic be absorbed), you can mix it with sugar or Kool-aid, or you can load it into a plain syringe (without needle!) and shoot it up your butt. (Rectal absorption is better and faster than oral, and a British medical text reports that the body is more tolerant of APAP taken rectally.) Whatever your means of ingestion, enjoy, and your bod will thank you. If you have any comments on or emendations of this procedure, email me.

For you doubters, why extraction works-
Extraction works because APAP, ibuprofen, and aspirin are hardly soluble in water, especially when it's cold, whereas opiates are very soluble in water.
Here is solubility information on APAP. This tells us that according to the Merck Chemical Index, APAP is: "Soluble in methanol, ethanol, dimethyl-formamide, ethylene dichloride, acetone, ethyl acetate; slightly soluble in ether; very slightly soluble in cold water, considerably more soluble in hot water; insoluble in petroleum ether, pentane, benzene."
Here is the information on ibuprofen. This tells us that according to the Merck Chemical Index, ibuprofen is: "Relatively insoluble in water; very soluble in alcohol, and most organic solvents."
And according to this version of the MSDS on aspirin, it is dissolved in room-temperature water at the rate of 1 g/100 g/water.
That is 1000 mg per 100 cc or ml of water (about 3 ounces) at 37 C--and the colder the water, the less aspirin dissolves.
In contrast, opiates are very soluble in water. Extraction works because the water dissolves opiates but not the aspirin, APAP, or ibuprofen. Extraction has a solid basis in chemistry, so quit worrying about it.
