check the original link for harm reduction stuff which i removed for brevity. also note the resulting mixture can be rather acidic, but this can be neutralized with baking soda. directions are in the link at the bottom of the page ^_^
Theory:
In modern DXM containing cough syrups (Usually indicated by DM on bottle or box), DXM is mixed with a large amount of sugars and fillers, which make drinking syrup miserable and add undesirable effects to the trip. However, since the DXM in cough syrup is attached to a HBr molecule, we can use the Acid-Base method to separate the DXM from the undesirable bits. Firstly, we use ammonia to turn the DXM into freebase. We agitate the mixture, then immediately add our non-polar solvent Naphtha to the mix and agitate. Let settle. Since the DXM is now in the non-polar Naphtha, we titrate the bottom red layer away and keep the clear naphtha. Next we add our lemon juice to the naphtha, agitate, and let separate. This time, however, we keep the bottom layer- That's the lemon juice that just pulled our DXM out of the Naphtha by turning it into a salt. There we are, Agent Lemon. On average, 10% of your input DXM will be lost after finishing all of the extraction, so you may wish to adjust the amount of input you use. Note that this process will not remove Tylenol or any other drug, so they will end up in your finished product. It removes Guaifenesin and inactive ingredients.
Materials:
✮ DXM containing cough syrup. Cough syrup containing Dextromethorphan HBr ONLY is ideal. Syrups that also contain Guaifensin are acceptable. Do NOT use any syrups containing any other active ingredients, such as acetaminophen. Products marketed as "Dry cough relief" are your best bet, but ALWAYS CHECK INGREDIENTS.
✮ Ammonia (clear, unscented, non-sudsy). Usually found at large grocery chains in the kitchen/bathroom area.
✮ Naptha or Lighter Fluid (Fluid should evaporate leaving no residue when placed on a mirror). Hardware store, smoke shops
✮ Citric Acid or Lemon Juice
✮ Large freezer bags (We will hang these up with our Syrup/Naphtha and Naphtha/Lemon Juice mixtures inside, to allow separation.
2 liter, threaded cap container, such as a soft drink bottle. Depending on the total volume of your ammonia/naphtha/syrup mixture, you may opt to use a large mason jar with a lid.
✮ Glass pot for boiling Agent Lemon on stove, or pyrex container/measuring cup for in microwave. (Acidity of lemon juice will dissolve metal/teflon into your mixture!)
Preparation:
Calculate your required dosage with a DXM dosage calculator and determine the amounts of materials needed. If using citric acid, prepare a solution in water ahead of time. For each bottle of tussin, use 1.5 tablespoons of citric acid in 4 ounces of water. If using lighter fluid, be sure it evaporates without residue. Try to avoid using Naphtha with plastic, if possible. Naptha can chemically attack and degrade many plastics. It is also extremely flammable. It is irritating to the eyes and skin. Vapors can be irritating to the respiratory system and in high concentrations can depress the CNS.
Procedure:
1. Add the cough syrup to the large glass bottle or sealable container.
2. Add in the same volume of ammonia (some excess is not a problem) and stir.
3. Tightly seal the container and shake vigorously for about 3 minutes.
4. Add in Naphtha or lighter fluid, approximately 10% of the mixture in volume (a 1/2-1 inch layer) and shake for another 5 minutes.
5. Pour the liquid into a large gallon-sized zip lock container.
6. Let the mixture separate for 5-15 minutes. The resulting product should have two layers: the Naphtha layer (which the DXM is now bound to) on top and the ammonia-syrup layer on the bottom.
7. Cut a small hole in one corner of the zip-lock bag to drain. Dispose of the ammonia-syrup layer and collect the Naphtha/organic layer in a glass jar.
8. Optional: Adding 8 ounces of water to the organic Naphtha solution and allowing it to separate will minimize the amount of inactive ingredients (ammonia, cough syrup). Repeat this stage 1-3 times.
9. Now mix the solution with the pre-prepared citric acid solution or lemon juice. If using lemon juice, add an equal amount into the solvent layer.
10. Shake vigorously for at least 5 minutes.
11. Pour the solution into the gallon sized bag and allow it to separate, wait at least 45 minutes for the separation.
12. Now the citric acid/lemon juice layer is on the bottom with the Naphtha layer on top. Drain and collect the bottom layer and safely dispose of the top layer.
13. Boil the lemon juice for a few (5-10 minutes) to eliminate any left over organic solvents.
14. Allow to cool, this is your finished product.
15. Drink and enjoy!
User McBludgeon notes:
I recommend just combining all the cough syrup, ammonia, and Naphtha solution in a glass blender. I am using an old Osterizer glass blender, and can fit 4-4 oz bottles, ammonia, and Naphtha that fills it right to the top. Then just blend for about 2-3 minutes. Works fine. And I only let it settle for about 1 minute before I cut the bag, making a small cut to make sure the separation has time to follow itself down the bag (I feel like if it goes too fast part of the ammonia layer rides up on the sides of the bag and remixes into the Naphtha layer, hardly worth mentioning though). Plus, a smaller cut makes for less loss of the Naphtha solution when I swap in a glass jar underneath the stream.
