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

I'd like to apologize for my aggressive attack at your tissue cold water extraction method earlier. I can imagine tissues work just fine, and I myself have substituted paper towels when I've ran out of coffee filters. It was me just being stubborn.

It's all good man. We all have an issue with a tissue sometime :)
 
Holy crap so I saved some of those caffeine crystals in the pictures above stored away for a bit, and today I did my usual cold water extraction (after a week or something long break), boiled it down to 15ml then chilled it in the fridge. You could see some small amounts of caffeine beginning to precipitate so then I added some of my previous caffeine crystals, when I came back in 15 minutes their was a massive amount of crystals, and I could literally see more appearing in front of my eyes as I spun the solution in a circular motion. I left it alone for a bit longer and when I came back it was pretty much just a white slurry, this is great! Once the crystal matrix starts I guess it rapidly beginning to crystallize and precipitate all the caffeine out of the solution.

I filtered it and got a clear solution and a nice amount of precipitate in my filter, I feel like i didn't even precipiate all the caffeine and I could add even more "caffeine crystal seeds" to my newly filtered solution and continued to precipitate more caffeine out but wow this is so cool.

science man!

did coldwater extraction on my pills and not high

so i crushed the pills up into a fine powder. the guide i read said no more than 20 ml of warm water per 10 pills. i had 9 so i used a little under 20. i poured the powder into the water and swished it around for a minute then poured it into a little bowl. while i let the little bit of water get cold i wetted a plain white t shirt and put it over a cup. after the water got cold i started pouring the water over the shirt filter. after i was done there was just a little bit of water left. and a shit ton of what i thought was that sludgy sticky APAP horseshit. there was so much of that stuff man it was ridiculous, like 95% of the damn pill is that damn horrible stuff. anyways i drank it and i dont feel anything. its been 30 minutes and nothing. i think i wasted my goodies :(

What's your tolerance like? I'm guessing that most of your hydrocodone was trapped in the water that you discarded as "sludgy sticky apap horseshit". You should have used more water than 20mL, If you're going to be consuming it orally, it doesn't hurt to use more water, as long as it's still cold, so then you would drink a less-concentrated solution but more of your hydrocodone would have passed through the filter.

I would highly recommend using a better filtration device than a T-shirt.. Try a coffee filter.
 
eh i can be good off of 60-70mg of hydro. any more and im just doing it to get extremely high/noddy. and yea ill probably get a coffee filter for next time, or a cheesecloth since they say coffee filters take forever. oh well, guess ill wait till next week or after to find out if i can do it correctly haha.
 
yes

put it in a glass baking dish and put a fan blowing over it overnight and scrape it up with a razor in the morning.

what opiate are we talking about and why do you want it in powder form?

ANY opiate you can run a CWE on is best taken orally
 
The problem I've ran into using a fan for ventilation is that it usually gets dust particles in the solution. I can't think of any reasons that you'd want to put codeine, hydrocodone, or oxycodone back into powder form.
 
For the rush/quicker onset.
But yeah, I understand that it has a higher oral availability.
Also, waiting an extra ~30mins instead of overnight makes a lot more sense lol.

Thanks for the info guys


EDIT: I wanted to put it back into powder form in order to snort it, and I'm talking about oxycodone.

You will hit a dead end whenever you want to turn a cold water extract into powder without a rotatory evaporator. There simply is no way around, you either have it or you don't. With the low pressure, your water can start boiling way below 100C so it protects your compound and allows obtaining powder form in less than 15 minutes. Watch this MIT video:

can i do a cold water extraction in vicoden, drink some, then save some for later.

my usual dose is 50 mg of hydro. can i drink some once it gets cold from the freezer, and save the rest? for later on?
 
I did a cold water extraction and wondered how much APAP was left in the coffee filter. I couldn't be bothered waiting for the gunk to take 4 days to dry so after the CWE I took gunk out, put it in a bowl and then put it in the microwave for 30 seconds. It started to bubble so I took it out. I then waited for it to dry out, which didn't take long, and then weighed the now rock-hard gunk on a scale.

Is doing this a good way of quickly determining how much APAP is left?
 
it's not really accurate because the binders and fillers are still inclusive and you've no real idea how much apap has ended up in your final solution. it sorta gives you a ball park number if you get your math right with the amount of binders and apap that may be in the gunk after a guestimate of how much has ended up in solution, knowing the total amount of each from the start point.

that's irrelevant when it's in a tiny bit of solution. the absorption rate differences are going to be negligible, unlikely you'll notice any difference at all whether it was in solution or simply a powder - which you're then likely to wash down with something.

What I meant was I would be snorting the powder.
Regardless, I have been just drinking the solution, it's much better that way.
 
First I'd like to say thanks to everyone who has contributed to this thread. It has been a great learning experience for me reading through the pages. As my tolerance has gone up for opiates, I've been using the CWE method for taking some Vicodin 10/660mg over the past few days. I must say that my stomach feels so much better already and I don't get some of the come-down symptoms I would experience when I was taking the pills whole. APAP free is the way to go. Thank you all again for sharing your knowledge/experiences.
