Harm Reduction Cold Water Extraction (CWE) Mega Thread & FAQ v2.0

DonaldGately said:
Does the amount of water used to perform an extraction REALLY matter, so long as it's enough to dissolve all the APAP (at room temperature, I mean, before cooling so the APAP precipitates out)? I didn't measure, but rather eyeballed, using probably about two cups (480 mL) for 5 30/300 codeine/APAP pills ...

Is the only reason not to overshoot, water-wise, that the filtration stage takes longer? Or am I missing something with the science, here?

You DO NOT want to dissolve the APAP/paracetamol AT ALL. The idea is to have enough to dissolve the codeine but not the APAP. Codeine is very soluble in cold water and APAP isn't, so you don't use much water.
I personally would not go over 100ml in total. The more water you have, the more APAP you will be drinking. Lucky for you that you only did 5 30/300s or you could have been in trouble. Please re-read the first post so you understand why you are doing this.
Good luck for next time!
 
There is an inaccuracy in the OP. It says that "Tylenol #3 (Aspirin, Codeine, + Caffeine in Canada)". Tylenol is not aspirin, it is acetaminophen. Tylenol #3 is acetaminophen and codeine (+caffeine in Canada). Acetaminophen is also called paracetamol in some countries and the active compound is sometimes referred to as APAP.

I doubt anyone is going to read through the pages of posts and notice this, so it would be awesome if the mods or OP could change the original post to reflect this.

How much Codeine do you all think it would take to produce the desired effects we all strive for? My problem id I'm on methadone 40mg a day. 10mgx4 times a day. I guess my tolerance is really high but I dont think 40mg of methadone is that high of a dose. I CWE'd 10 codeine 12.8mg pills today. I thought 128mg would be suffeciant. Well, nothing! I have 16 pills left. CWE all of them? My final solution is not clear, its bright white, like milky water. I know I did the CWE right/ Is that normal for codeine/ibuprofen mixture? Im on methadone for chronic pain and I thought the codeine would help cause my bodt is getting used to the methadone cause the intense pain is creeping back every day. I used 1/2 cup of water with 10 pills. Very cold distilled water. Once the pills were dissolved, I mixed it up and ran it thru a dress shirt first. Lots of grose stuff left in the shirt. I squeeze the shirt to get all of the water out and the crap left is now chalky. I didnt bother saving it for further filtering. I ran that solution thru a coffe filter. Both the filters were wetted with very cold water as well. It tasted terrible so I thought it was right although it was milky. It was ice cold. I used frosted pint glasses from the freezer for all of this. Where did I go wrong? Any suggestions would be great. Thanks.
 
Sorry to bump this.

So I found a bunch of Darvocet 100's. I know these are not hcl, so they cannot be seperated from the Acetomeniphen through a cold water extraction. However, I had an idea, and I just wanted to know if this could possibly work:

My idea is that I would crush up the desired ammount of Darvocet, and place the powder in a spoon. I would then take very hot water, and pour that over the powder and stir vigorously, and then draw up. I would assume that this would get rid of a good ammount of the APAP, and as propoxyphene-N is hardly water soluble, it would be left in the spoon.

Is there any reason this would not work? To be honest I have very little experience with CWE, as I've rarely ever used codeine,percocet or hydrocodone, so please let me know if there is something flawed with my "hypothesis".

And yeah, I'm not expecting much out of Darvocet, but since they're free, I figure I'd like to give them a shot even though from what I gather, they're pretty lame.
 
Hey everyone! Im new here and been reading post after post about cwe. I have done it once and got a very milky solution. I used 6 5/500 hydros and I know I used too much water :( pissed me off! Plus I didnt wet the cloth first so it went up the sides..ugh! The methods here seem much better than the one I went by at another website. I get my pills thursday and am going to try again. I have been on these things for over 5 yrs for bulging discs at about 8 a day..I also take milk thistle, lethicin and NAC daily to help my liver handle the load but lets face it, its got to have done some damage! :( I hope I have better luck thursday! Exactly how much water should I use and I guess I should filter twice? Thanks for such a helpful thread...my liver thanks you most of all! Lol
 
^ I have always used about 60mL when I did CWE so I would use around that much if I were you or use 10mL per pill to be on the safe side. If the solution is milky then it still contains APAP or binders.

The liver is a pretty resilient organ and will repair itself with time if you allow it to do so.
 
Thanks for replying wiggi!.:) Ill take your advice on the water amount and also strain again till the liquid gets clearer. As far as the liver tegenerating if given time, I hope.I give it enough time inbetween scripts as my doc only gives me 60 a month and there are 10 -11 days I dont have any..3 a day doesnt do crap for me so of course I run out! Those days I take 500 mg sodium naproxen..
 
Sorry if this has been answered but, with the fact that 1g of apap absorbs into 100ml of water at room temp, does it mean that if you only use 100ml of water, you can only absorb 1g of apap?

Not that I want the apap, but hints to me that, if you use 100ml or less you won't go over the specified amount written on the pack, per one dosage.

So if you do fuck up with temps and filtration method, you atleast know you won't go over 1g of apap.

Is this theory correct?
 
I'm confused about something...is the filter what keeps all the APAP out, or does water also destroy some of the APAP was well when you're dissolving the crushed pills? (Assuming you have just codeine/APAP pills).
 
cold water extraction question

So I want to do cwe's as effeciwntly and easy as possible.. I read here a few people use buchner funnels and that's the way to go... was wondering if someone could confirm/disagree with this and if any kind is better then the others or if they're all basically the same. Thanks a :)

CWE Questions

I've recently done CWE of codeine I evaporated the water to get a powder and have ended up with a shiny browny yellow powder that seems to be allot more(bout 2 gram maybe more will weigh when I have time and post exact weight) than I should have ended up with(codeine used 600mg) .
can anyone tell me what I've done wrong.
Thanks
 
Don't forget caffeine goes through to, if it's 8mg codeine 15mg caffeine that wud make 1.8gs, and ofc a small amount of apap gets thru which makes 2g
 
They were just co-codamal no caffeine(30mg codeine 500mg paracetamol). Could binding agents have got through?

Just came across some "Acetaminophen, butalbital, caffeine and codeine" capsules
Strength:
325mg / 50mg / 40mg / 30mg

What's the best CWE method for these to remove the Acetaminophen and do i need to worry about the Butalbital??
thanks
 
Hey bro, Im not gonna tell you that 3,000mg of apap a day WONT hurt you, because everyone is different. However, ive been taking Norco 10/325 for 6 years. For the last 3 plus years, I usually chew 4-6, 3x a day and have no real issues. I had blood work done a few months ago and it showed slight liver elevations(when I say slight I mean literally say if it was posed to be 800 it was 806) on a couple markers which is absolutely normal for anyone who takes any level of apap on a regular basis for long periods of time. Its soley do due the medicine consumption and nothing permanent. That being said, everyone is different so error on the side of caution if your worried about it. Nothing more scary than sitting and wondering if you have done something and waiting to see if you get sick. The governemrnt lowerd the daily prescribed amounts of APAP to be 3200mg or less just recently but that is only to provide a cushion and absolute safety barrier. Its pretty rare to find someone getting in to trouble even at levels around 4500-5000/day.
