Assuming you bought some of unknown quality, how can you either a.) determine purity, at least a little, or b.) make it more pure (i.e. filter out or otherwise remove adulterants)? I'm not sure b is possible with a lot of effort, but any advice would help.

Also: for you cokeheads out there, what do you like to do with it? My friends always drink alcohol as well, but I'd think the alcohol would just knock out any coke-buzz you'd have going. Is there anything that makes the experience that much better?

Just out of curiosity. :)

google search cocaine acetone wash and you will probably get a whole bunch of shit just find the one that seems the most legit.

Limit yourself 1 line every 45 mins thats how you can tell if its good. I usually split a fith of good alcohol such as remy or somesort of vodka between 2 people when we get an 8ball Im over coke though, its to much of a letdown when its all gone and you feel like a jackass for wasting your money. Ive seen it cause a lot of damage. it has the potential to ruin you,for me more than any other drug. Then again if you play your cards right you can benifit from it.

Thanks. :) But goddamn, chemical supply store? I hope we've got one...

Yeah, the plan was me and my friend would split an 8-ball between us. But like you said, cocaine is a pretty bad drug on the whole... I won't indulge. He paid, after all, so I figured I'd just help him instead. If my friends are going to be cokeheads, I want to make sure they're at least getting something out of it. :D

Do this:

Acquire a small amount of acetone at a hardware store (even Wal-Mart has it). Hell, get it at Wal-Mart so you can buy Epsom salt there, as you'll need it as well.

Next, go home and take a hand-full of MgSO4 (Epsom salt) and put it in the oven at about 200 for about two hours. Take it out and funnel it into your acetone container. Shake it a while and then let it sit for a while. I leave it alone for about an hour. (This will do a damned good job of making the acetone nearly anhydrous, which is good because cocaine HCl is very soluble in water. We want to minimize loss.)

Finally, get a filter and pour some of your acetone into a vessel (read: cup/jar) containing your broken up cocaine. Mash that shit and stir it around for a while and run it through a filtered (coffee filters are just fine) funnel (look up how to fold filter paper to fit a funnel if you don't know how). You may want to try just pouring the liquid out of the cup and giving the bitch a few more washes. Once the solution is pretty much a heterogeneous mixture of acetone and (presumably) CocHCl, throw it through the filter one last time and scrape all the stuff that sticks to the bottom of the vessel onto the filter paper. Squeeze the filter paper so as to make the cocaine into a large solid mass, doing this will expel more of the acetone, as well.

After pressure has been applied for a while (10-15 min), place your damp mass (usually triangular in shape, unless you used a Buchner funnel, in which case you probably don't need to be reading this), unfold the paper and let the residue evaporate under a lamp (at close proximity). I'd recommend 48 hours of drying time, but you may find that with smaller quantities your product will dry faster.

Good luck.

Edit: Hm. I guess that link pretty well summed it up. Oh, well.

Man? The solubility of cocaine HCl is damn near 2g/ml. Acid/base, then CWE.

You can clean it up after that if you wish - and getting it to full pharm grade is probably a good thing... but that obscene solubility is probably going to get it over 90% anyways.

Ethylcocaine : as much win as cocaine will ever get. ;)

Yes. Definitely this.

Cocaethylene, It's pretty much the most basic potentiating method for a drug: drink.

Kind of like benzos, but better, 'cause it's a cocaine-esque potentiation, not a drunkness-magnifier.

No worries, you summed it up in a much more clear manner. :) Thanks!

Can you elaborate, please? How I do this? :o

This (http://www.mediafire.com/?4xjelhxwjde) may prove useful. Some literature on the subject.

I wish I could give you rep. Wunderbar, thanks again! :)

I was worrying over the three-day-preparation in the link doosh posted, but reading over your method it seems much quicker. I'm printing it out now. :D

Get a bit drunk first, 4-5 drinks. Do some lines, get high. Have another drink. Do another line or two. Repeat the last two steps until satisfied. :D

For the comedown try and find some benzo's, or drink it off if you have to.

Of course you need some cigs if you're a smoker, and maybe some ganj too but Coke and Weed make me crazy unless there's a downer or two in the mix. That's just me though.

Clean it with an acetone wash if necessary. Make sure you know what you're doing too, and do a small wash first as a test if you're learning.

I'm stressing the having alcohol and/or benzo's part for the comedown. A coke comedown is hell sometimes, especially with larger quantities. Being sedated enough to ignore it is a godsend.

Remember, the most important thing is that you have fun. EZ.

Yeah the LeJunk acetone wash will do great things for your cocaine!

Remember, the most important thing is that you have fun. EZ.
For sure. :D Thanks!

I looked up acid/base extractions and wow, it's a lot of work. I'd like to try it just as a chemistry project (no, really!) but where to get methanol and hydrochloric acid and all that... hmm...

Edit: A hypothetical chemistry project. I'd never actually do it, 'cause I'm afraid of jail. :p

For sure. :D Thanks!

You shouldn't need methanol (wood alcohol, post your proposed procedure, though, 'cause if it calls for methanol, you might want to use it, it's just that all a/bing methods for cocaine I'm aware of don't require methanol) but HCl can be purchased at hardware stores under the name "muriatic acid."

Thanks, that makes it much easier. :) Here's the method I found (methanol mentioned at bottom):

The basic steps of street cocaine purification with an acid base extraction are these:

1) dissolve cocaine in distiled water (1 gr cocaine in 60ml water ) in a glass beaker. Filter the solution to get rid of any water insoluble impurities. The 60ml water is kind of arbitrary, you just need enough water for the cocaine to properly dissolve and for the ammonia solution to be weak, i.e not overshoot the ph. Also you need enough water so that the basification proses will be easier (stirring wise)

2) titrate (i.e add very slowly, no more than a few drops each time) ammonia hydroxide solution of around 10%. It doesn't really matter actually you just need it to be very dilute (5-15. While vigorously stirring with a non porous rod (preferably coper but glass or plastic is good). At this point you must be very very careful. The theory is that the impurities will react with the ammonia BEFORE cocaine. In any case, when the first drops of ammonia hit the water the solution will get white, stir and stir for 3-4 minutes until the solution starts becoming clear. Quite possibly the impurities will start to get stuck to the walls of the beaker and the rod. A copper rod is preferable because it forces things to group up because of electrical affinity making them to stick on it instead of just precipitating also try not to touch the beaker while stirring, that tends to form crystallization nucleons that will precipitate, you don't want that. Keep adding ammonia and stirring like this. When the beaker and rod are visibly dirty by the impurities change beakers and clean up the rod. You do this in order to keep the impurities sticking to the rod and beaker instead of precipitating to the bottom. After enough ammonia is added you will observe a white crystal like deposit to the rod. It ought be like snow. This is cocaine base. At this point CHANGE BEAKERS and clean the rod. Some cocaine will be lost, but this is for the best. Keep adding ammonia and stirring you will see that when the rod and beaker are saturated the cocaine base will start falling like snowflakes to the bottom of the beaker. When the precipitation ceases (no more white cloud will be forming when adding ammonia) and the water smells strongly of ammonia the precipitation is done and you have cocaine base. Do a thorough water wash at this point. I.e add distilled water, stir and filter.

3) Filter out the precipitate which is cocaine base. Slightly press the the filter to rid of any redundant water. Use the filter to cover the cocaine base and dry it in a heat lump/the sun/or with cool air until dry to the touch, then dump the powder to a ceramic plate, chop it up and let it dry until fully dry (when it is like flour and chops up with no residue its dry, leave for a day or two). An efficient way to dry it up is using a desiccant like anhydrous magnesium sulfate. Just sprinkle some of that around the cocaine ceramic plate and cover everything air tight with a glass bawl or something, after a few hours it will be dry

Thats cocaine base, SOME impurities will have turned to their base form as well, for example amphetamine base is a stronger base (thus weaker acid in its salt form) than cocaine so it will react later, so you will not be able to get rid of it. BUT it IS slightly soluble in water (while cocaine is not) so the water wash of the cocaine base will get rid of it.

Converting cocaine base to cocaine hydrochloride:

there are several methods to do this, i will describe in detail the best in regards of end product quality and give an outline of the other.

1) dissolve the cocaine base in ether (1gr of cocaine base per 15ml ether). Filter it to get rid of any ether insoluble cuts that remained from the ammonia treatment
2) dissolve 38% lab grade hydrochloric acid in acetone (0.25ml of hcl acid per 15ml acetone per gram of base
3) add the acetone/hcl acid solution in the ether/base solution. A visible white reaction will form, crystals will start precipitating in the bottom. When the solution is no longer reacting (it will be clear no white clouds), gently stir it, leave it for a few hours for the crystals to properly grow. Run the rod up the beaker, over carrying some liquid, if no crystallization happens you are good, its done. In any case leave it 3-4 hours to properly crystallize.
4) discard the ether (leaving the cocaine in the beaker!) and do a very thorough acetone wash in order to remove any traces of ether left. After a few pours of acetone in the beaker filter out the cocaine base (just like le junk describes nothing fancy). Perform a final acetone wash over the filter. Fold the cocaine in the filter and let it dry for a couple of days. Thats called an empanada

voila cocaine as pure as it can get

the other method (ether free) is done by dissolving cocaine directly into acetone. Then dissolving hydrochloric acid (38% lab grade) in methanol. You use 0.25ml of hcl acid per gram of cocaine base and double that of methanol i.e a 1:2 solution of hcl acid/methanol. You gently swirl both beakers by hand (like rotating them) and mix them, cocaine will start precipitating. After 2 hours stir everything and let for another 4-5 hours. Then filter out the cocaine acetone wash and let it dry.
Courtesy of "epote" at drugs-forum.co.uk. It seemed to me that the Cocaine Handbook didn't mention the use of methanol either, and someone mentioned that, to which he replied:

im prety sure that the cocaine handbook describes the procedure just as swim tells it. Actually this is where he learn the procedure:P

the handbook says specificaly that the WATER in the hcl acid is of no significance because you use so little of it.

in any case, if using only acetone+hcl acid the crystallization dosnt happen very well because hcl acid is VERY miscible with acetone and cocaine base is VERY soluble in acetone so no significant nuclei are formed to begin the crystallization. What happens is that something resembling a yellow oil will stick to the bottom of the beaker and to collect crystalls one must leave everything evaporate.

One needs some sort of non polar/alcohol type solvent to force the crystalls out of sollution and into proper crystallization

Think he's got it wrong? No idea how reliable he is. Are there better methods? :)

I've never heard of the methanol method and if it were that easy, who the hell would a/b it? Everything else seemed pretty on point from what I read. I'm tired, though, so I'll give it a more thorough examination tomorrow.

All right, so I was really tired last night and didn't really understand what he was saying, as I had just skipped down to the bottom.

He's saying that you dissolve the cocaine base in the acetone. When I read it last night I thought he was retarded because cocaine (hcl) in insoluble in acetone. It makes a little more sense now, maybe. Basically, HCl + CH3OH → CH3O+H2 + Cl－. Protonated methanol and a chlorine ion. Without doing any research, I'd guess it's possible for the protonated methanol to donate it's H+ and have it react with the chlorine ion and cocaine base to form the salt we all know and love but I'm pretty sure a similar situation occurs when you straight dissolve your base in acetone and simply add the HCl, I don't know why he stresses the use of ether.

When you add your HCl to the base/acetone mixture, try to do it slowly, while gently swirling/stirring the receiving vessel. An Ice bath wouldn't hurt, either. Don't be in a hurry when adding the acid, scraping the edges while you stir will help, too.

Bang that shit son.
