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

Yeah, but with 7x500mg, that wouldn't be that dangerous a dose on its own. ofc, you want to get rid of as much as possible, and it sounds like you've done that. From what you've described, spot on.

Hang on, there's nothing in the filter? Remember, there's only 3.5g of paracetamol to get, so it won't look like a lot, but you should be able to see some kind of chalky residue on the coffee filter.
 
It's making me think ive done it wrong but there's no anything in the water after filter but the filter looked empty just a small amount of white gunk
 
Yeah, it won't be a huge amount of gunk in the filter. As long as the solution is free of white sediment, it should be fine. I'm logging off now, so I hope I've helped, peace.
 
stoptheclocks: On th internet, there's these guys called trolls, they think they're being clever in saying deliberately inflammatory things, but they're actually just idiots. You've been thrown in at the deep end, but you should just ignore their peurile bullshit.
 
patronising him today, demeaning his grammar (by which you apparently meant spelling) yesterday. you certainly know how to make friends and influence people dont you? if i were you, i would realise youre in the wrong - and leave me to have the last word. i'll do my best to repair any lasting damage inflicted on our new members by yourself


pm me if this guy gives you any more trouble, stoptheclocks. best not encourage him further

Well I speak that way because I'm Scottish. Can't help it just slang talk over the internet and text. Have done it for years.

Another question for you guys.

I am doing a cwe as we speak and I am filtering it through 3 coffee filters. I crunched paramol up best I could with 2 spoons then put it in 100 ml of cold water. Stirred for a good 3 4 mins and now pouring it through the filter. Is this correct?

Also I will let it sit after and what are the bad signs again after filtered ?

Cheers

Paramol will aways be cloudy because of the Iodine oxide i think its called, the coating round them. Ive done paramol extractions before and they are always cloudy. I only use 2 filters. i Dont bother crushing the pills i just leave them in water and stir every so often for 30 mins.

You dont even need 100 ml of water, 50 ml will of been fine with that many pills. Hell even 25ml if its just 7

When i have all the gunk in the filter what i do is i take it off the glass and put a new filter on the glass and squeeze the rest of the water out of the gunk into the new filter.

You have around 1 gram of paracetamol in the water as you have used 100ml of water, and 2.5 g's in the filter it wont look like much lol

Paramol solutions are known to be cloudy no matter how well filtered but, as Babylon mentions, any paracetamol should sink to the bottom if left for a few minutes. With three coffee filters you should be fine but certainly won't hurt to leave it a few minutes to double check - better safe than sorry with paracetamol.

One other tip from experience is to make sure the pills are crushed as finely as possible. My first few CWEs didn't work because I didn't take the time to really get it fine. I took to putting my pills into a a folded piece of paper - or perhaps into an envelope and folded over so it doesn't split when you whack it. With them contained in paper it's easy to bash hell out of 'em to get it all nice and fine. If you're extracting codeine/DHC you may as well extract as much as possible so you have a better idea of how a given dose feels to you rather than it being a bit different each time cos some got left in big, uncrushed lumps one time and didn't the next and so on.

Other tip I use is to use the coldest possible water to keep paracetamol to an absolute minimum in the finished solution. I tend to leave a bottle of water in the fridge when I know I'll be doing CWEs so I've always got ice-cold water to hand. Alternatively, just run the cold tap for a good while to get it nice and cold. Paracetamol doesn't like water colder than ~4C and - combined with using as small a volume of water as possible - this should give you the best, safest CWE solution.

Enjoy the warm and fuzzies =D

EDIT: For clarity, I always crush the pills to a fine powder because I tend to want my codeine as soon as possible being a bit of a drugpig. I've never tried it with whole pills and patience but am sure that will work just fine too. It's the inbetweeny stage of semi-crushed pills and not taking time that's no good.

The filtering is where i get impatient at times. I find if you use 50 ml of water on 32 tabs you end up sometimes waiting like an hour if not more for it to filter. So i end up squeezing out the water early a lot cos im fiending for it. >< but if you use just like 25 ml more water it can be filtered in like 20-30 min. Lame when you want to to do a 64 pills dose because i really dont wanna use more then 50ml of water on each pack
 
^Use a bigger funnel, I did my last CWE on 64 tabs, used a 2l bottle cut as the funnel and recieving vessel, worked a treat. Or, set up two side-by-side smaller extractions.

magnificent. simple, easy to understand. are you a chemist? if not you should be. its great when a real chemist enters a thread here - clear, concise information, yknow? i can definitely tell when i see one, competent ones anyhow. im just glad you arrived before he any more innocent stomach linings were harmed
 
A pestle and mortar is a fucking brilliant investment if you do this often.
 
Let the tool do the work, mate.

Chefs and tradesmen know. Why do something that'll do itself? Stick the tabs straight into water, they'll break up straight away
 
I think that probably depends very much on which particular pills you have, BB. Different brands have different binders/fillers. Some are like concrete and are a nightmare to break even with vigorous application of a heavy blunt instrument, others are quite crumbly and presumably dissolve dead easy. I'm mostly meaning prescribed ones as that's what I've mostly used (there are loads of different generic brands and you just get whatever the chemist has in stock) but presumably applies equally to OTC pills whether branded or generic.

I know my early extractions didn't work so well and it seemed to be down to not crushing the pills properly. There'd be chunks of pill left in the filter at the end so whichever brand they were they certainly didn't break down straight away even with a bit of a head start.

Also might be worth a reminder that we're all talking about standard codeine/DHC containing pills (co-codamol etc) and not the soluble or effevescent forms which obviously will dissolve instantly in water but will also be somewhat lethal if you try to CWE them as all the paracetamol will be in the solution.
 
Yeah, I only ever use the cheapest ones, the red-n-white box chalky cheapy chappies. They just turn to slush. ofc, not everyone will be using them, it was wrong of me to assume they would be. Thanks for pointing that out.

Yes, NEVER use effervescent co-codamol ("medicine bubbles", as I called them as a child), doubleplusungood.
 
Hi everyone.

I got some 30/500 codeine phosphate/paracetamol and went ahead with cwe. I crushed up 2 tabs, mixed with a bit less than 25ml cold water and chucked it into a wet coffee filter. Was all clear until I gave it a squeeze and then it got milkier. I presume this is down to the filter not being fine enough? Should I put it through 2 and give it a squeeze or just leave to filter for a bit longer to make sure it's all there?

I backed off the shot anyway since it wasn't a lot of paracetamol. I'm not sure if the effects I felt were placebo and I smoked a joint too. If I can handle roughly 60mg could I safely double that next time? Want to make sure I'm filtering effectively first too.
 
Hi, Trainfriend - welcome to BL and EADD :)

Your problem is a simple one: you're not supposed to squeeze the filter. If you do you're just undoing all the filtration you've just done. Well, not all of it but enough to make it a bit of a waste. If you're only wanting two tabs worth you really don't need to filter as that's a perfectly safe dose of paracetamol to be taking. Unless you are taking other meds containing paracetamol, of course. If 60mg is enough to get you feeling fine then I'd honestly skip the CWE and just pop the two pills. It's really when using 8/500s or wanting doses of codeine that would require multiple 30/500s that need CWE.

Obviously nobody can tell you exactly what dose would suit you, but 60mg is on the low side and 120mg is still comfortably within the lower end of most recreational doses. Maybe have an antihistamine on hand in case you get the itchies but you should be fine with 120mg. Just remember not to squeeze the filter. It's better to just add another pill to make up for any loss in filtration than to squeeze a load of paracetamol into your nice, clear CWE solution. As long as your water is cold and you're not using huge amounts of it, just let it filter through at its own pace, check the solution is clear and that no gunk has gotten into it (filters tear sometimes) and you're good to go.
