Codeine Extraction

Status
Not open for further replies.
your calc is wrong. 100mL dissolve 43.48 GRAMS and you've got 307 MILLIGRAMS (0.307 grams)

to dissolve that you'd need about 7mL but thats waaay to little water to work with. The rough guide is 2-3 mLs of water per tablet.
 
Oh, no shit. *facepalm*

Cheers for that. I'll try extraction one more time, then back to Rikodeine if it doesn't work.
 
I use 50ml of water for ~600mg of codeine this works fine and the table supports it. Have a look 100ml of water @ 21c will dissolve 142 GRAMS of codeine, not MILLIGRAMS. I think you are getting your units mixed up.

Also using 700ml of water will allow 7 grams of paracetamol to dissolve into your water not to mention any solids that manage to filter through. This is way too much paracetamol and will cause liver damage if used regularly.

I fail to see how you are loosing the codeine, personally I use ~50-100ml of water and put it in the freezer until it gets down to ~5c stirring occasionally. I probably lose ~25% of the codeine due to it being stuck in the sludge and/or fighting to dissolve with the massive amounts of paracetamol, however its still a decent output.
 
Just tried extraction again tonight. Had 30 tabs (384mg codeine) and used about 75mls water. Allowing for 20% loss, I was shooting for about 300mgs. Followed the methods for extraction pretty much to the letter and left it in the fridge to filter while I went to the pub. :)

Only had 2 beers and when I came home I squeezed the remaining water from the coffee filters and drank it down. Usually takes about 45 mins to come on, so when I didn't feel anything after an hour, I took 60mg in crushed tabs hoping to bring it on. Nothing whatsoever; so disappointing.

Should I be using something with a looser 'weave' than coffee filters, like fabric of some sort? I can't see how this could be a problem though, as the codeine is supposed to be dissolved in the water. Don't think it's tolerance cos I never go more than once a week, and I've only done 300+mgs once. That was 190mg dihydrocodeine (syrup) and 120mg codeine (crushed tabs). That was an intense high that lasted around 2 hrs (way longer than just codeine highs, assuming this was from the dihydro)

Any further suggestions? I'd really like to be able to do a CWE successfully. not least to stop having large amounts of other nasties like ibuprofen and paracetamol.
 
Maybe you are one of the unlucky ones that can't process codeine into morphine and hence its ineffective with you. Should be using the finest filter you can so nothing but the liquid gets through.

You mention you had 60mg of crushed up tabs, I'm assuming these are 10/500 tabs which means you had 3g of paracetamol, you really don't want to be doing this especially with alcohol, shocking bad for your liver.

Nah, like I said the dihydrocodeine had me going hard. I assume it's processed the same ie into morphine.

The tabs I'm using are 12.8mg codeine and 200mg ibuprofen, so that makes 1000mg ibuprofen. Lots of ibuprofen, I know, but there are 800mg IR ibuprofen tabs that are sometimes prescribed, so I figured 1g wouldn't be too bad.

Nope the dihydrocodeine itself causes the high, and a very small percentage is converted to hydromorphone although an article I read on here suggests that its so small it doesn't cause the the high. So an enzyme deficiency would not stop dihydrocodeine from getting you high.

Also I'd still avoid taking that much ibuprofen regularly, its not good for you at all.
 
ive heard codeine is addictive and can cause withdrawals. just wondering roughly how often and for how long would u need to be taking codeine to get withdrawals?
 
Using four times a week for a few weeks will cause withdrawal but it's quite mild. More of an anxiety than an actual physical withdrawal.
 
btw guys,

haven't read through the latest of this thread, but just reminding you,

the table, often cited,
saying codeine is literally MORE soluble at lower temperatures,
is probably inaccurate.

200ml is a reasonable amount to work with.
will not dissolve more paracetamol than is recommended to be taken within 4 hours anyway by pharmacy,
and will be large enough not to have too bad percentage losses, in the filtrate.

(imagine you will lose 10ml (or whatever) of water in the filtrate,
if you only use 50ml, that's 20% of your codeine gone.
if you use 200ml, its only 5%,
while still maintaining safe levels of paracetamol.

either way, no matter what the figure,
the levels of paracetamol are safe with both methods,
but I have only 1/4 of the wastage of codeine,
that the people who use 50ml have.)

1. i find it extremely hard to believe that 100ml of 21degC H2O will dissolve 143g of Codeine.
doubt the accuracy of these data.
also, inverse proportional solubility to solvent temp? ehhhhm..... very rare, especially unlikely in the case of codeine.
Why would codeine and water, with solvent-solute bonds (ion-pd/pd-pd/H-bonds), have HIGHER entropy, than codeine and water, as molecules?

2. THERE IS NO POINT IN USING HOT WATER AND COOLING.
this is not fractional recrystallization!
simply use the cold solvent initially!

All questions I asked as well but I doubt anyone here is qualified to answer them, maybe ask in advanced discussion, post a link here if you do.

Can I add a number 3 to your argument?

3. I have tried dissolving 1000mg of pure paracetamol (from a capsule) in 200ml of water and it was literally impossible, whether the water was hot or cold. I personally think that paracetamol is even less soluble in water than many internet sites state.

That's exactly right; it used to be said on here a lot that DHC got converted into DHM and that's what caused the high, but I remember posting a link to some research that debunked that in one of the DHC threads a while back. Looks like you're unlucky, blau. :\

+1. I never do any of that complicated extraction process; just a quick dissolve and filter through a shirt and I'm blissful. ;)

Well that's not really advanced discussion; the ADD guys would probably not appreciate that being posted in their domain.

Bugger. Gonna try the extraction method on a few friends soon just to make sure.

May not be much to gain chemically, but warm water does dissolve it faster. :)

I assume that, once dissolved, the tablet ingredients are dispersed evenly throughout the water. So say I have 100ml of filtered water, and it's slightly white in colour. If I put 100ml in another glass, then dissolve small pieces of tablet in there until it's the same colour, would this indicate the level of binder/ibuprofen (the codeine is clear when dissolved)? Or is ibuprofen also clear when dissolved in water? Just asking to put someone's mind at ease who thinks the extraction only gets rid of the binders, not the ibuprofen.

so,
"Heat water > dissolve tablets > cool water"
is faster than
"Crush tablets > dissolve tablets"

??


get a mortar and pestle, about 60 seconds, some cold water
and it the entire process takes about 3 mins.
 
Or...


... you could dissolve the pills in a teeny-tiny amount of hot water (very quick) and once dissolved add cold water and then chill in the freezer for about 5 mins.
 
I mean wikipedia says per 100mg you get 500mg of APAP.
So i freeze frist sperate top layer off through filtration then freeze again and then defrost a there only a little apap floating around or that not still stuck on bottom insoluble in water. i then drink cold with penergan works great and i recon i get less APAP than having panadol.
any comments on my method welcome please

I assume you mean 500mg per 100ml. Where on Wikipedia does it say that? Anyway it will be different each time you do it, depending on how many tablets, the total paracetamol content, the amount of water etc.

Besides all that, even if that calculation was correct, if you used 200ml water, you'd only be taking 1g of paracetamol, which is the recommended dosage! So probably not worth doing all that, just a quick dissolve and filter.
 
yeah.

200-300ml, at 10-15degC.

1. crush tablets (pestle&mortar). 60 seconds.
2. dissolve tablets in 200-300ml H2O, 10-15degC, stir. 50 seconds.
3. Filter through two panels of GOOD kitchen roll (check your filtered solution for visible particles), or a dress shirt. squeeze through after it starts getting slow. 60 seconds.
4. drink. 10 seconds.

3 simple, safe minutes to opiate fuzzies.
