    SWIM recently came across a few various samples and wanted to test each to get the results. SWIM put each of the samples in bleach. The first had trails that fell to the bottom quickly with smoky trails following slowly behind it. The next three had a weird behavior. They all produced varying degrees of slow smoky trails and various degrees of fast trails shooting to the bottom. But all of them spread out instantly when they hit the surface of the bleach. Subsequent tests confirmed that only 3 out of the 4 did this. What could this be? Has any else run into similar results?

    SWIMs friend had tried a few of these samples and a few weeks later came up positive for amphetamines and meth in a pretty thorough drug testing. SWIM's friend previously had a prescription for adderall but has never knowingly done meth. Could there have been some in these samples? All of them seem to be of high quality.

    Is it possible to use the Marquis, Mandelin, Mecke's, etc reagents to test what may be in these samples more conclusively?

    Checking purity using chemicals / testing kits/ bleach tests thread

    Hi all, I need an information, if anyone can explain us the procedure of checking the purity of cocaine and which chemicals react with cocaine and change colors so that we can see the purity in percentage ? I know that pure cocaine melts at 195 degrees, but that is not reliable procedure, so we need more reliable way to determine the purity in percentage.

    Thanks in advance

    Re: Checking purity using chemicals

    Because if it is poison you're dead, if it is bunk you're ripped off. Does swiy think a dealer is looking out for your health or his bank account?

    If you're looking for quantitative data you need analytical equip? Does swiy have access to HPLC, GC-MS or other and a standard reference material for this drug? If not you may have some problems.

    One can do an A/B work up and take the weight of the product after and divide by original weight to get an idea of the purity..but it is not quantitative by any means as it assumes everything you end up with is the pure compound and not some type of "full spectrum" extract.

    Re: Checking purity using chemicals

    I know the thread title is checking purity using chemicals, but has SWIY considered simply purchasing a cocaine test kit? SWIM finds the "EZ Test White" quite effective for most purposes, though it will only show the purity of SWIYs coke on a relative scale as opposed to the actual purity. After a quick reagent reaction (the simple process will be outlined by the kit manufacturer), SWIY just compares the color of his solution to a graded color chart provided by the manufacturer. With the EZ Test White, there are 5 different color-grade categories, with 1 being the lowest amount of cocaine and 5 being the highest.

    EZ Test White is insensitive to the usual, "inactive cuts"--the discussion of which is not allowed in the cocaine forums--as well as many other common so-called "active cuts/adulterants" which include, but are not limited to, many of the various -caine alkaloids that are often added during cocaine manufacture. These alkaloids are typically added (or, perhaps, never removed due to poor, rushed methods of extracting the "cocaine" from the Cocoa leaves) because many of them, such as lidocaine and procaine, mimick the numbing properties of cocaine hcl--however, none of these alkaloids contribute to cocaine euphoria, have numerous negative side effects and many are also much more toxic than cocaine itself. Many of these adulterants can be removed with the simple acetone wash outlined in LeJunk's massive thread on cocaine purification. After washing and testing the sample using the EZ Test White, a "very high cocaine content" (or something similar) rating would indicate that said aforementioned regeants are not present--or at least not present in any significant amount. If SWIY gets this far, he is well on his way towards experiencing good quality cocaine. SWIY could stop here if he wants, after all, washing with acetone and using a cocaine test kit is above and beyond what 99% of users will ever do, however...

    After determining the relative purity of SWIY's cocaine, he could, if he were so inclined, also purchase the various regeant tests available on the market (and even available in package deals with the EZ Test White) in an attempt to discover which chemical agents were adulterating his cocaine. Basically, such regeant tests will provide SWIY with a chemical X that will react, in some specific way, to a cutting agent Y (if present). Perhaps this is what SWIY meant by "checking purity using chemicals." Well, if this was indeed SWIYs question, I can't say anymore than that the regeant tests for practically all of the well-known cutting agents are easily available via online suppliers, as identifying said chemicals would require a discussion of the various cuts that they test for, which is not allowed. That said, a few different regeant tests that react with the more common cuts would probably give SWIY a pretty good idea of what adulterants are in his sample.

    With this ample knowledge of what SWIYs' cocaine is cut with--presuming that the sample is cut significantly--SWIY could then proceed to use the various extraction methods outlined right here on DFs by posters like LeJunk and Epote to target the specific adulterants of concern. If I remember correctly, LeJunk's first post in his gigantic purification thread includes detailed procedures for extracting amphetamines, ephedrine and pseudoephedrine. To attain the level of true conissieur, SWIY could follow Epote's Acid-Base extraction thread and then oxidize it for the most bang for SWIY's buck.

    The moral of this story is: any responsible cocaine user will, at the minimum, perform some crude test for quality/purity on an unknown sample and wash it with acetone. For most practical purposes, this is all SWIM would categorize as "necessary" in the purchasing and usage of cocaine. Going deeper than this requires more time and effort--effort that many swimmers refuse to put forth because they'd rather snort low-grade shite thats been stomped all over than learn some cool chemistry stuff that's actually pretty easy--but SWIM highly recommends it. Hope this helps.

    sorry, the dealers that swim know do not like to poison their customers. you're right, if it is bunk then you're ripped off-profound! that's why swim suggested trying it. if it's bunk, then don't buy it. no need to do any mad scientist experiments, determining the quality of cocaine is not hard to do.

    Re: Checking purity using chemicals / testing kits/ bleach tests thread

    SWIM cleaned some Cocaine using the acetone method, and it appears to be worse, which could only mean that there was no Cocaine to start with. There is no euphoria in the washed batch. The unwashed is better. That is pointing to meth as being what is getting you off the way SWIM sees it. SWIM will get better at testing.

    meth is insoluble in acetone.

    perhaps what was removed was caffeine or smt like that, caffeine hcl is mildly soluble in acetone...

    Anybody tried out that E-Z test white ?

    Swim was just wondering if anybody tried That EZ test (white). It's supposed to tell you aproximately the percentage of cuts in your coke (so you know it's about 20, 40, 60, or 80 % pure). Is it easy to use and is it reliable ?
    Thanks in advance ...

    best thing is to wash cocaine, acetone wash or A/B extraction

    swim tried the ez test white an it came back with a coffee like sample but the coke wasnt all that, swim doesnt think they work or the dealers are using a cut which reacts to ez test white
    swim washed it with bicarb an it jus went to oily globe, swim smoked oily globe an it had kinda half a buzz but dint taste as it should.
    taste of coke seems ok an if swim looks closely can see the cocaine crystals in it, swim hasnt had any coke which actually tasted as it should for a while. so this was easy to spot.
    it numbs as it should not like the cuts do. an as swim said the tests were 70-90% but swim doesnt think it was that strong,

    anyone else getting similar results from these tests or had coke do similar stuff when washed

    oliwog added 53 Minutes and 41 Seconds later...

    jus to add aswell when swim tastes some of wot was made up it burns aswell as numbs and has a strange taste doesnt burn for long tho about 30 seconds but really numbs.

    EZ test kits

    thought it was time to make my 1st post, just before i do just like to say what a great website this is, have found nearly all the info i have ever wanted to know about drugs here. have found answers to most of my questions in the forums but couldn't find anything on this quiry.

    the EZ test kit for cocaine purity

    my friend got this coke recently and the effects were right up there with pure coke that he has had in the past. my friend then got some more from the same supplier and used the EZ coke test to test for purity. the test showed that it was top of the range coke. however the effects did not seem as strong. more had to be taken to get the same effect. my friend had been taking the previous lot of coke prior to this on a regular basis for about 2 weeks and wanted to know if the reason the effects were not as strong was because he had developed a tolerance or maybe because the EZ test kit was incorrect and the coke was infact cut.

    does anyone know if a tolerance could have been built up in just a couple of weeks ?

    or could the test kit possibly be wrong ? and if it could be wrong is there a better way of testing purity that is easy to do ?

    purity testing is difficult. please read the existing threads grouped under the thread prefix "purity".
    all street cocaine is cut. which is why swiyou's best bet is to purify it, via an anhydrous acetone wash for instance (see the sticky)

    Heres a question I would love to know the answer to lol.

    what is the chemical used in the 'ez test white' kit
    that is mixed with cocaine to see the purity of the substance?

    Re: Tek - Make your own Drug Reagents

    reposted from this wonderful thead on making one's own reagents for various drugs, thanks again !

    Tek - Make your own Drug Reagents

    -------------------


    This is not the EZ Test White reagent, but it is a reagent for testing for cocaine.

    Scott test

    Chemical Name: Cobalt Thiocyanate

    Preparation: Dissolve 2.0 g of cobalt (II) thiocyanate in 100 mL of distilled water.

    Procedure:
    Place approximately 2 to 4 milligrams of a target substance in a glass test tube, then add 5 drops of cobalt thiocyanate reagent. After shaking, 1 or 2 drops of concentrated hydrochloric acid is added, and the tube is again shaken. Ten drops of chloroform (or a similar solvent) are then added, and the tube is vortexed, and then allowed to settle and separate into two layers. The color is then observed.


    Also, here are some other reagents that may be of interest.


    Dille-Koppanyi Reagent, Modified


    Tests for: Barbiturates

    Solution A: Dissolve 0.1 g of cobalt (II) acetate dihydrate in 100 mL of methanol. Add 0.2 mL of glacial acetic acid and mix.

    Solution B: Add 5 mL of isopropylamine to 95 mL of methanol.

    Procedure: Add 2 volumes of solution A to the drug, followed by 1 volume of solution B.

    Duquenois-Levine Reagent, Modified


    Tests for: Cannabis

    Solution A: Add 2.5 mL of acetaldehyde and 2.0 g of vanillin to 100 mL of 95 percent ethanol.

    Solution B: Concentrated hydrochloric acid.

    Solution C: Chloroform.

    Procedure: Add 1 volume of solution A to the drug and shake for 1 min. Then add 1 volume of solution B. Agitate gently, and determine the color produced. Add 3 volumes of solution C and note whether the color is extracted from the mixture to A and B.
