This thread may be inappropriate and hasn't been covered the way i like so:

what are your master techniques for CWE for those that perform this often?

My method

1. rubber bowl fill with as little as scolding hot water as needed to cover pills (and a few mL more)
2. everything dissolves, stir, break all the pills (broke my coffee grinder)
3. put bowl into freezer for 30 minutes at most

2nd step

1. get a glass, a coffee filter, one of those plastic coffee filters
2. use paper towel to insulate the plastic coffee filter (as they let shit through)

3rd step

1. poor contents of bowl into filter (that is in glass)
2. if it's frozen just let it melt
3. in 20 minutes I get crystal clear codeine :)

I only use preps with acetaminophen.

basically my secret trick is the freezer and the plastic coffee filter.

btw if your glass gets frozen; put it in the fridge.
ahhh my liver. post your tips.
 
I crush the pills into powder with the end of a kitchen knife and a bowl (just make sure the pieces don't go flying everywhere) to make it dissolve faster. I don't use hot water because it might destroy some of the opiod.

I don't have a plastic coffee filter, but I use cloth (rip off a part from an old shirt) and it seems to work fairly well. After the water is done dripping I squeeze the rest of the goodness into the cup but make sure no apap leaks through.
 
how clear is your extraction? mine are crystal clear and bitter as can be. Good thinking on the hot water; i use it to dissolve the pills but it's not boiling water so i doubt i'm losing anything (if i go by qualitative testing).
 
I dont find any difference in using room temparature water in terms of cloudiness of the resulting water, that seems to rely much more heavily on the quality of the filters used.

If the end product is at all cloudy then I instantly chuck it away.
 
^ i would refilter lol send me ur cloudy stuff next time

what are some estimated yeilds with some of these methods?

cold/warm water
freezer

how much does this stuff play a role in yield? I've probably done 1000 extractions by now but I am just trying to become more efficacious with my codeine :)

The reason you use cold water in a cold water extraction is because codeine is highly soluble in cold water, and APAP is not. Using warm or hot water for the entire process is totally counter-productive. You're supposed to use lukewarm water to dissolve the pills, and then freeze the solution (making it cold water) and then filter the result, no?

If I'm misunderstanding you can you clarify what you meant to say here? It seems to me it might not effect the "cloudiness" of the water, but instead dissolve some the undesirable APAP into the solution with the desirable opiate.

^This is a good point as well.

To find yields - Get a scale and weigh the "before and after" setup, it's not hard.

Yes you are right in what you say, just from my personal experience the freezing part of the extraction doesn't seem fully necessary as a) I'm an impatient asshole and have skipped this many times and b) I don't think that there is a dangerously significant difference in the amount of APAP that will dissolve between temparatures from 0C to 25C. I might be wrong about this however but I've never seen reason to believe otherwise. I rarely do CWEs though, if I did them often I would make more sure of this fact, obviously I'm not advising this to anyone, the less APAP the better.

I find that most DHC pills in the UK will always turn out cloudy no matter the filters or temparature; must be one of the fillers they put in them (paramol pills in particular).

(when I said chuck it away I do usually try to re-filter it but it rarely works, so is probably down to fillers more than APAP)
 
Dont think its the speed of the change in temparature but more the temparature that effects APAPs extent of dissolution. I have looked for data on this before and not found any. Warm water will dissolve more yes, but I dont think its much more ...

.... Sekio? :D
 
All that matters is that the resulting broth is ice cold. You don't neccesarily have to start with boiling or hot water, it's just that physically it is easier to dissolve things in hot water than cold.

The process is called fractional crystallization - you are supersaturating a solution of acetaminophen and then lowering the temperature causing it to crystallize and crash out of solution. The speed of change is not important (in fact the temperature doesn't have to change at all, it's just really hard to do a CWE with 10ml of ice water), all that matters is that you end up with a cold solution so the codeine stays dissolved while the APAP isn't.

Things like povidone, cellulose etc will "cloud" even the most APAP-free solutions as they are extensively water soluble. And also high MW polymers. These are seen in Canadian T1's and I bet they're the cause of cloudy DHC extractions on the other side of the pond.
 
i've had to deal with cloudy solutions from certain brands here in Canada. I avoid these like the plague. Sometimes when i have my solution filtering in the freezer this white stuff will crystallize all over the filter, is that the apap?

I re filter this stuff (apap sludge) again and again to get max yeild. Basically until there is no water left. If i freeze a solution right before the water freezes all that white stuff freezes, is this again the apap and binders?

...but not impossible :) I extracted AC&C codeine pills every day as 'maintenance' for a while, using a process that's easy, quick and involves no temperature change whatsoever.

Basically, what I'd do is use an oral syringe to filter a tiny amount of ice water through the ground-up pills, leaving me with barely any liquid to drink, and pretty much caffeine-free at that. I believe it's called a super-saturated solution? Anyways, I can elaborate if anybody is interested, this technique easily generates a high amount of impurity-free codeine in 10-15 minutes once you get the hang of it.
 
I'm gonna piggy back on this thread, for the sake of not wasting space with a similar question.

If you dissolve hydrocodone in water, but don't do a CWE, does it hit you faster than swallowing the pills whole? I only ask because I have 7 7.5 lortabs, and have never done a CWE, and would like to chew them up, for faster onset, but the taste/texture is just too bad, and I'll most likely throw up. I know I can mix juice/soda with the cloudy hydrowater, and it will mask the taste though.

So basically, even without a CWE, will hydro/apap water hit you faster than other methods?

Also, if I did decide to take my chances with a CWE, how much hydro do you lose in the process? That's my biggest reason for not doing it...I fear I'll lose a few precious mg's, and it will make the whole thing counter productive.

All that tylenol will be a buzzkill...dont do it! Learn the CWE or you'll just feel like a giant pile of gut-rot.
 
CWE losses are rarely more than 10%. The majority of the loss comes from the "leftovers" in the filter and the precipitate. (Or if you're a clumsy person and you spill your extract.)

Dissolved hydro will only hit moderately faster than whole hydrocodone pills. The only delay you're removing is the disintegration of the pills.
 
I'm attempting a CWE right now, wish me luck, lol. I started with just 3 pills. SO i smashed up the pills in a bowl, added a little water, (maybe 1-2 ounces?) I hope that's not too much....anyway, I stirred it up, put the bowl in freezer...am going to wait about 15 minutes, take out, filter through coffee filter, ring it out as much as possible(without tearing filter) and drink the resulting liquid. Correct?

By the way, is is possible to snort the post-CWE liquid? since it's essentially pure hydrocodone, it should be safe, right? Anyone tried that? Who am I kidding this is bluelight I'm sure people have tried it...anyone had good results from trying it?
