How confident can you be with Cold Water Extraction results?

[Hear Me Roar]

Unless you go to super great lengths, you won't get 100% of the apap out.
As long as you stick to the guidelines, use a suitable filter, you can be confident to know you have at least 70% of it out. Probaly a lot more. Considering the daily guideline for consumption of apap in a healthy adult is 4g( not sure if they lowered it to 3g now) and in those 10 tablets there's is 5g, even removing 50% of the apap would mean consuming 2.5g. Which even though constant daily intake could be damageing, now and again, it is relatively safe.
You just have to remember, decent filter.
Crushed fine powder.
Dissolve in luke warm then chill as low as you can go without freezing. Some people say it doesn't matter the about the before temperature. But I find I get a clearer solution is I first dissolve in luke warm water. Guess my preference.
Keeping to those 3 main guidelines you can be confident you have removed enough apap to not damage your liver.
Oh.. patience aswell. When filtering, leave it, no poking or prodding to make it drip faster. You're pushing crap through the filter.

The real confidence comes in drinking it afterwards. No matter how many times I drink it or what I add to it. It always makes me gag and has to be washed down with a cup of water.

i used 8/500 co-codamol for 2 years in a row and i used 9-15 packs a day, each time taking 480mg of codeine so using 3 packs. (one pack had 160mg, 20 tabs) oh good old times, hehe. what a screwball i was. chasing that codeine high that you only feel the first time and then again if you do it two weeks later. but no, i did it once, and then 2 years every day. then it was on to 3-methylfentanyl (the only opiate available on the streets in our city of 500k+ people, also capital of the country) *ot*
i personally believe i got rid of enough of cwe not to worry about it.

You'd be better off with a codeine/ibuprofen tablet mix. APAP/Paracetamol is really, really bad for your liver. Ibuprofen I believe is worse on the kidneys but far more forgiving.

Ibuprofen causes stomach bleeding and other GI issues (one study found people to have significant stomach bleeding after just 3 days of high-dose use), kidney damage/cancer, and is hard on the liver (but not nearly as hard on the liver as APAP as far as I know), so a CWE should still definitely be performed. Iboprofen overdoses can be serious and fatal, but the likelihood of dying from an ibuprofen overdose is much lower than dying from an APAP overdose.

My personal choice when deliberately taking one as a painkiller is ibuprofen over APAP though FWIW.

EDIT: Also, as someone mentioned below ibuprofen seems more difficult to remove via CWE.

confidence lies in the person that does it

if your inexperienced with it, than you really have no way to know exactly how its supposed to look.

be confident in yourself, and good outcomes will come. Especially when you got all these old heads coaching you along

Sorry mate, i think that's incorrect.

In addition to what swimmingdancer mentioned, paracetamol preparations tend to filter out much better than ibuprofen in my, and i think many others experience. i think you'll find that ibuprofen is more soluble in water than paracetamol, though that might be incorrect. Furthermore, ibuprofen, as an anti-inflammatory, will depress your immune function and inflammation; extremely important processes considering the bane of addiction.

also, i think its easier using paracetamol preparations, the best way is just to drop it in the water, let it sit for 5 minutes, stir, and its completely dissolved.

I'll tell you that a few friends and I have tried to do it.
And we planned it out for a week, got all excited and everything.
So finally the day came and we brought everything together.
We ended up putting too much crushed up pill mixture into the filter, and turned it into a yogurt almost.
In the end we filtered it at least ten more times, only to come up with a cloudy liquid that tasted like absolute SHIT.
The buzz was terrible, so we popped some Ol' Connors, smoked some thanksgiving turkey bags and vowed never to do it again.
But I wish you better luck with yours :D

i think you'll find that ibuprofen is more soluble in water than paracetamol, though that might be incorrect.

It's the other way around. Ibuprofen is very insoluble in water; less than 1mg per 1ml even at warmer temperatures. Paracetamol is more soluble in water, and it becomes more soluble the warmer the water is. Following is the solubility of paracetamol at different temperatures. Source.

Temperature (celcius) & Solubility ([g P/kg water]): 0=7.21; 5=8.21; 10=9.44; 15=10.97; 20=12.78; 25=14.90.

150mls is plenty enough and theoretically impossible to contain large/dangerous amounts of APAP.

This is really dangerous advice. It's only taking into account the paracetamol that has dissolved. You can definitely have an extraction in 150mls of water that contains a dangerous amount of paracetamol because there's always the chance that solid paracetamol will come through, if it hasn't been filtered effectively.

It isn't theoretically impossible for 150ml of water to contain dangerous amounts of paracetamol - you are only taking into account that amount of apap that can dissolve in that amount of water. As footscrazy said, it's more than possible that solid particles of paracetamol could get into the mixture if the filtering isn't effective - meaning that there could easily still be a dangerous amount of APAP in the resulting extraction.

I have tried CWE using ibuprofen (panafen plus) 3 times, the first was really milky even after 3 filtrations so I dumped it. The second came out only slightly cloudy using the exact same method. The third was a little cloudier than the second even after extra filtration so to be safe I didn't drink it either.

I have done many more using paracetamol tabs and always ended up with a clear or very near clear filtrate.

Using: Luke warm to dissolve then cooling to between 0-4 degrees C.
2mL water per pill. Doubled up coffee filters. Filter once to get majority of solids out then squeeze into another set of filters.
