View Full Version : Cold Water Extraction: Hot Water?

11-04-2005, 07:35 AM
After some research on the topic of cold water extraction, I've come across some information on various web pages which suggest that one use hot (not extremely hot because hydrocodone is sensitive to heat) water to initially dissolve the Lortabs.

Should cold or hot water be used to initially dissolve the hydrocodone from the Lortabs (I know that acetaminophen is insoluble in water).

Here is the outline for the procedure that I am speaking of:

1. Crush up the substance in a bowl so no clumps remain;
2. Take the powered substance and place it in a cup with "cold" tap water;
3. Stir the mixture until all of the powder is dissolved (does the acetaminophen need to settle in the
bottom of the cup prior to filtering, or should the substance just be thoroughly mixed?);
4. Place a filter (such as a coffee filter) onto a second cup and secure it to the cup with a rubber band;
5. Pour the mixture into the filter and allow it to filter through the coffee filter into the second cup; and
6. Re-rinse the acetaminophen which remains in the filter to obtain more hydrocodone.


1. Must the same amount of water (measured) be used with each extraction (or should one use watever
amount necessary to dissolve the substance)?
2. Should the filter be placed in ice water prior to use to reduce the possibility of the substance
being absorbed by the filter?
3. Should cold water (ice water?) or hot water be utilized to dissolve the substance?
4. If cold water is utilized, should the water essentially be ice water instead of cold "tap

Other research indicates that after the Lortabs are crushed up and the water added to the mixture, that the substance should be placed into the freezer until it starts to crystalize. Is this step necessary? The same research indicates that an acetaminophen crystal should be added to the mixture. Again, is this necessary?

Here is the exact "cold water procedure" I am speaking of (questionable methods underlined):

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.

Of course, this is only research as I would never participate in, or condone any illegal activities.

My apoligies for the long post!
