Newcomers - Cold Water Extraction: Method Do's & Don'ts

Thirty-two grams of paracetamol? 8o

No wonder they split. Once you get to that stage then you have to do the filtering in instalments and be very patient indeed.

That's why past a certain point CWE's on OTC products are more trouble than they're worth in my opinion.

nah i was doing it in 2 seperate ones, one pack of paramol is 16gs, so i was filtering them seperately, they still split.

All filtered with a t shirt now, but its so cloudy/milky looking. Plenty left on the t shirt but still wary. Im sure it would of let only a few g in. Doesnt only 1g of paracetamol dissolve in 50ml of water or something?

thanks

edit: downed it anyway :p might order some milk thistle or something healthy for the liver as im sure its taking a beating with all the kratom, phenibut and paracetamol lately. Not to mention a bottle of vodka on friday.
 
Just for clarification, do you have to warm the water prior to cooling when performing a cwe on Tylenol #2 or #3? Some say there is no need for the warming process, others say it's essential. Can I start my CWE with crushed pills mixed with cold water, then filter? Is that simple?
 
Boiling the water will drive off any dissolved gases, so ought to make a bit of room for the codeine. It should then be cooled down. The warmer the water, the greater the probability of it picking up some of the (unwanted) paracetamol. Room temperature is plenty warm enough.

If you were extracting a load of pills, it might make more sense to do a first, coarse filtration with a T-shirt and then re-filter the cloudy first filtrate through a coffee filter.

^ I've never heated it myself - codeine is freely soluble in cold water. With you on the double filtration technique, much better, coffee filters always clog hopelessly otherwise!
 
There's a CWE megathread here which has a lot of good info, or feel free to ask - it's a simple procedure but one that is essential to get right :)

(APAP = paracetamol in that thread, stoopid 'mericuns ;) )
 
Is 240 mg codeine a lot for a first try with no opiate tolerance? I plan on drinking 1 beer and smoking some weed. Maybe some speed as well, we'll see how that goes.

What are your thoughts on this?

You should totally filter it with something better than a t-shirt. Also it would help to filter more than once. Especially if you're doing this often.
 
Hmmmm..... 240mg.....
Tis a tricky one for me as I've not had zero-tolerance for far too many years.

I want to make sure you're safe, so I would suggest that, if you do take 240mg, then make sure you don't have a beer until you feel the full effect and slowly nurse yer beer.
 
I've taken codeine before, about 3 times.
All i've had till now was pills with 15mg codeine, 24mg caffeine and 500mg APAP.
First time i cwe'd 8 pills, so that's around 120 codeine (around 100-110 in reality, since some is lost in the cwe process). Felt something... nothing that you could put your finger on. Possibly some was placebo - but I did notice I was a bit more talkative, like on a small dose of a good stimulant, stuff was more funny, nothing more though. Some of the effects were probably also due to the caffeine in the pills.
The third time - only one worth mentioning - I did around 180 mg of the codeine and caffeine pills (but could have been as low as 140 - I kinda fucked up the CWE that time - spilled some water, didn't re-filter the leftover APAP/binders, did it in a haste) and I smoked some weed. Before smoking the weed I did feel a non-placebo feeling, it was a calm/confident state of mind, my body felt warmer/heavier but not so notticeable. After smoking the weed the experience was quite nice, the weed really felt like the missing part of a really nice and enjoyable buzz.
This time I got a nurofen plus pack, which doesn't containe caffeine (yay) - just ibuprofen and codeine. I didn't like the edgy feeling the caffeine gave me, I felt as if it spoiled the codeine experience. This time, I'm also doing a proper CWE (I'll re-filter the gunk 3 times, got all the proper tools, I will probably extract most of the 243mg of codeine (about 210-220 for sure).
Should I drink it all at once or should I take half, wait an hour and then take the other half? Does redosing work with codeine? I think I've read somewhere that the second dose, if taken after the first one kicked in won't be properly metabolized so it might not be fully effective or not work at all. Is this true? I really don't wanna screw this up because those nurofen plus pills are damn expensive.
 
How would I lay the kitchen roll over the bowl or is it best to squeeze some into a top of a bottle and pour the solution like that.
Also took codeine once for about 2 weeks and it took me about 3-4 phosphate pills and weed to feel the effects.
I have took zopiclone today is it safe to take them with codeine and I took 100mg tramadol for 2 days a week ago will this have any effect on tolerance
 
If you can't get any coffee filters, then just lay them ontop of a pint glass with an indent so you can pool the solution in it.
And an elastic band wouldn't go amiss if you're worried it will fall into the glass.

Yes, just don't be silly with the dosage and you'll be fine. And having taken Tramadol so long ago will make no difference what so ever with regards to safety.
With regards to tolerance, it's hard to say. It may be elevated a slight amount, but it was only 2 days and 100mg. So it will be negligible at best.
 
What am I wanting to be left on the top of the paper towel,
has anyone got any pictures of it being done with the paper towel filtering method as I never tried this
before and I rarely take paracetemal.
 
You're wanting to be left with all the solids (Paracetamol and fillers) and squeezing as much "water" as you can from it.
No pics as far as I know.
If it's your first time doing a CWE then I'd really suggest going for the coffee filter method.

Maybe someone else who's more versed in the paper towel ways can be of more help.
 
i find the best way to do a cwe is quickly, grind pills to dust, add to 100ml(for 64pills-2 packs) and stir, put in fridge till contents settle, then pour solution through filters and leave, let the water drain until it comes to a stop, then you can squeeze to get the remaining water out but i find that you dont really need to, the codeine is already in the water, squeezing it tends to burst the filter and allow the sludge into your clean filtrate, the taste is fucking rank so have a drink ready!

using paper towels isnt advised, i think using a tight weave tshirt would be safer (fold it on itself till you have a few layers, make sure you wet it before you use it)

or do what i used to do and use both, put a paper towel inbetween each layer of your tshirt, i would use 2 or 3
 
Can I use any t shirt and do I just put it over the glass can anyone take me a pic and show me how it would be done with paper towels on top of the cup want to make sure I won't do anything wrong.
 
For dealing with the taste I find just diluting it with orange/blackcurrent juice does the job or just chase it with some proper orange juice.
 
Right I tried it with 5 in first time, Clumsily I split some but still got some to filter through 2 Kitchen rolls
The water first came out less cloudy than before so I decided to filter again this time the water was clear and spots of paracetemal and some clumps could be seen at the top, I then squeezed the bottom of the paper and the water was still clear.
Since I spilt some I decided just to try 3 more and same again 2 kitchen rolls over the top of the glass and I watched the water drip down it did it alot slower this time (I reckon I squished the kitchen roll in better) and the water was clear with a tiny bit of cloud at the top.

Did I do this right?
 
Indeed, 1g of paracetamol (had to stop myself typing APAP there, bloody Americans in BDD) will dissolve in 100mls cold water, so you're already going to have a minimum of 1.5g in 150mls, more if the water is warm, and more if your filter is rubbish.

2 sheets of kitchen roll always worked fine for me - if the filtrate is clear and it's not poured through the filter (a decent filter will drip rather than letting all the liquid through quickly) then that's a good sign. Squeezing is generally a bad idea - I find it always tears the filter or lets a load of cloudy gunk through and I have to start again..
