The process of making cocaine is a long one, with many parties involved. This usually causes the cocaine’s purity to take a considerable hit. Dealers, traffickers, and suppliers may all add something to the drug, to get more income for themselves from it, making pure cocaine hard to come by.

But what are the differences between pure and cut cocaine, and what does cocaine do to you if it isn’t pure?

Pure Cocaine vs. Cut

Pure and cut cocaine can have many differences. The cut version of the drug is essentially the drug with added ingredients, which take away the purity. It is done by dealers to enhance the weight of their dosage and therefore make more cash. However, it also benefits the dealers in another way, as the cut version of the substance is even more addictive.

Unlike real cocaine, cut cocaine is not the glistening white color, but often a murky brown instead. It can often smell differently too, due to as when cut, the drug usually smells like many of its added extras, like baking soda or rat poison. However, on rare occasions, it will retain its bitter chemical cocaine smell, regardless of whether it is pure or cut.

In addition to the differences in appearance and smell, when cut, the drug can be considered even more dangerous than pure cocaine. This is partly because it is even more addictive. However, the added cut ingredients also make the drug unpredictable with side effects. Whereas real cocaine has well-known effects, cut cocaine can produce all those effects and much worse. Users could have allergic reactions, drug interactions and general side effects that they are not expecting. That is why when cut, the drug is often far more deadly than its purer version.

How Abusers Clean Cocaine

Impure cocaine is incredibly dangerous. It has all the dangers of its purer counterpart but with the added effects of the user having no idea what they are putting into their system. This makes it necessary to purify cocaine.

There are a few complex, chemical procedures when it comes to washing cocaine. However, many of these the average person would struggle to accomplish.

When the substance is manufactured, at the beginning of the process, it is washed. Cleansing is done with the use of acetone, or diethyl ether. The process removes impurities from the cocaine hydrochloride crystals. However, leaving the impurities, or adding them throughout the manufacturing process adds weight to the drug, and therefore it can be sold for more.

Cut and pure cocaine are off law. The use of both poses health hazards, as well as legal consequences.

Testing Cocaine Purity

For drug abusers, purity of cocaine is important, so they often conduct purity testing. Cocaine purity can be tested with a purity test kit. These kits provide instructions, spatulas and the test itself.

The test helps addicts recognize how pure the drug is, from less than 10% to over 90%. It shows this with a color-coded reaction which changes depending on the purity of the sample provided.

Another method is the spoon method. The users heat the spoon with the substance on and a small amount of water, and see how much of the substance dissolves, using a filter.

Another way abusers use to check the purity is how much does cocaine cost? Cheaper cut versions of the drug are usually impure, as it has been mixed with other substances. This way isn’t as surefire as the other methods, but it helps to give a general idea.

Cocaine Purity – How Does It Affect One’s Health?

Many are aware of how bad cocaine is. However, many are unaware of how drastically the level of purity can affect your health. Low purity levels may even slightly change the symptoms of a cocaine overdose, making it harder to identify.

When the drug is pure, it has an array of terrible and negative side effects. The impure drug can have effects on one’s health as well. Not only do the ingredients it is cut with changing the high, but they also change the level of addiction, as well as the symptoms.

    I’m probably being super dumb despite being a 65 year old experienced drug user, but I thought if the cocaine dissolves in water that’s a sign it’s good and what’s left is crud. But you say if you heat the spoon what dissolves is the additive. Confused.
    • Lily
      The substance is 100% water soluble indicating this method is totally inaccurate. The term “cream” indicates that when the substance is pinched and it dissolves into nothing – it’s a good day to go snowboarding.
      • John
        would you say its relatively safe if it comes as a white chunk straight from the brick?
        • robbo
          No, coke can be cut ten times over and then pressed back into a brick. Just because your dealer gives you a hard chunk of ” coke “, doesnt make it any more valuable or potent than baking powder.
        • awana
          No, dealers mix and cut and put the s**t in a press to rerock it
    • GiJoe
      .i agree, it has been my experience that it dissolves completely, then the high is better than if it has anything not dissolving.Does baking powder or whatever it’s cut with sometimes dissolve too?
    • ed
      the idea of washing is getting all the crap out so the disolved stuff isnt the good stuff
      • Swia
        all wrong and not even reasonable..when you dissolve .”powder” in water good or bad the water is what has the pure s**t in it because pure power is water soluble the gunk is the s**t it was cut with..and if its cut with too much backing soda it will never dissolve any it turns into a foamy thick mess that will not separate even with filters. My point is I bang the coke so all of my cocaine goes into water. When you draw out the water taste the reminiscence left..definitely not any cocaine its usually very granular like sand taste like nothing…Also it’s ually not baking soda(unless you got some s**t so you might as well toot it up)‍♀️☝️So if you dissolve “powder” in water and there happens to be a little bit of reminence (gunk) the clear stuff you draw/filter out is the pure Pure, the gunk is the cut and such DEFINITELY not cocaine? That’s my lesson in trying to help you understand the substance you are doing…its kind of impact..IGuEsS…! Be safe and keep on living..only got life have a damn fun time..but be smart with your buying..
        • Martho
          Hey bro, I’m looking for assistance. I bought some and it looks like a bunch of shards. They break into powder but overall it just looks sketchy. Can crack break into powder? I’m curious if you have tips so I know if I have good stuff or if I should stop
    • John Hawley
      Thats right because cocaine does not dissolve. Same as rocking it up with bakin powder
    • Barbara
      That’s exactly right I was confused by this comment to
  • Smokey Adams
    How accurate r thw test kits?
  • Samon
    Good coke stands out in a room. You walk in and you can smell it even if its hidden a In a drawer. It wont break up easily it will chunk. Up when being chopped. Also you wont do lines alot mainly bumps. Also fish scale like shards will be in it. Trust me on this.

    I’m not addicted to cocaine, I just love the way it smells! The purity of coke on the street is generally tested by dropping a smidge into a shot glass of bleach: pure cocaine dissolves, while traditional adulterants either sink or color the bleach. However, the latest “supercut”, levamisole, also dissolves in bleach, making it impossible to distinguish it from cocaine using this test.Anhydrous acetone will wash off some cuts and contaminants, leaving the coke behind on the filter paper.Anhydrous (200 proof) ethanol, will dissolve coke from the filter paper, and anything left behind on the paper is junk. Allow the ethanol to evaporate at room temp, and you get nice crystals.As Lily mentioned, pure coke will mostly melt by body heat, when pinched between the thumb and index finger and rubbed back and forth. It will leave only an oily residue. Most cuts have a much higher melting temp, and remain a chalky powder.Pure coke is also hygroscopic, meaning it absorbs water / moisture from the air. Good coke is soft, and will look like it is melting when left exposed to air for 30 min or more.Do not begin a relationship with cocaine. It will ruin you.
    • Boog sug
      It. May ruin you but you will have a hell of a time in the mean time!!!
      • anonymous guy
        I first tried it about 3 months ago due to curiosity. Now i use it every weekend. I wish I never tried it, wasted a lot of money on the stuff and I was warned not to try it because id love the buzz too much. Safe to say its ruined me.
        • Oliver
          I hope you’re doing better now. Everything in moderation.
  • Nossy
    You know it’s coke when u have a tiny amount and it tastes chemically fresh, strong smellling like petrol to the point you can smell it in someone else’s pocket, slightly moist and clumpy and hard to bash up. Just a small amount sparks massive self confidence. . Very hard to come across nowadays
    • Friendly advice
      Ain’t hard to come by just got to know what to look for and don’t let people mug you off… Take my advice stay well clear cus wen u find that real you’re hooked trust

No clumps no chemical smell chopped easy with a blade didn’t make your mouth all numb but gave you a great high. Of course you had to. know the source probably just like today…I quit the s**t because it was all crap after the early 90s
  • G

  • Coke
    I have been a coke user since 13yrs. I had my taste of coke in Goa(India).. Got a freeze from a female friend and my whole mouth was numb..then I realized that was a nice feeling.. And then I snorted my first ever line..The neurons in my brain where firing on cylinders(confidence, rule the world and the likes). In Goa the purity was around max 40%.So when we binge buy a lot (i have partaked in 20-25gs, 6-10 ppl passing through but I was constant). Then I came to Dallas.. And the cheapest $60 coke has a heavy diesel smell but f**ks ur nose in the delivery burn. I had a dealer who used to charge $100/g..thats way better than $60 s**t.. Now I have become a coke connoisseur.. And I only strive to get the best.. Best is always expensive.. I have heard that there’s a coke so good that it could $300 a g in US.. So the coke i get from a different dealer and gave a few lines to apparently the biggest dealer in Dallas was better than what he has, the biggest dealer put my coke at 70% purity.(no burning during and after a binge sesh). So my dealer gives my another variant of coke but and after binge.. My nose is hurting af.. So which is the best method to test the coke’s purity.. Af course going to the farm is the only way we will know how cocaine feels like after it goes through the process.

    You know you got good s**t when you’re nervous to do another big hit! I use to have only one dealer that I knew had it, his stuff was garbage and cut with caffeine.. I hated it, it was weak as hell and burned if you snorted, plus it made you jittery and just burned out feeling.. plus it was so weak you wanted more with in a few minutes. I knew people who could get better stuff but I only wanted to do it once in awhile and crappy shit didn’t make me wanna do it all the time.. well it’s been easily a month or more since my last use and my buddy came over today and brought some, I said what the hell, loaded me up about half what I normally do cuz it’s been a minute and holy s**t, it f**ked me up! Ears ringing loud, sounds echoing, vision became tunnel vision, throat had a weird taste then went numb, chest tightened up and heart started pounding!! When he wanted to do more I was nervous as hell! So I just did a lot less.. about a quarter of what I would normally do with the other stuff and it fucking hit me harder than the other stuff I get if I did a lot of it at once.. also I’m here cuz of how strong it was, trying to figure out how pure it was.. saw the comment about if it melts when you pinch it and leaves and oily residue, that’s what this stuff did, first time I’ve ever had coke do it, it was also in chunks and he broke of some and chopped it up, it was soft, strong smell that you taste/smell when you do it, I bang mine btw, way more intense! I’ve never liked snorting, even if it hit me faster and stronger snorting, if still bang it, hate snorting.. I know it’s stronger banging than snorting, just using a theoretical situation to show my dislike of snorting lol.. also, if you don’t have a scale, how can you tell how much you have, is there pics of what an average say gram amount looks like?
    • Blowfeld
      Dude wtf are you even talking about. Are you on the caffeine cut s**t now?
  • Joe whip
    It is extremely simple to test purity. Im QA specialist for a few guys. All u need the correct spoon soda water and a small knife. Add the powder soda water to spoon. Turn stove on and put spoon on. After enough heat it will bake and rise like a pie. Begin to stir until oilseperates from water. Scoop that oil let it harden. Weighin powder before and the hard piece after gives u an idea ofwhat percentage is pure but these days theres comeback which looks lie real oil. Im the best in the city and have had bricks sent back due to impurity.
  • Simon wilkes
    So I recently got my hands on some so called coke but I was told it was cut with baking soda. I wanna know how to recook it so I can get most of the coke out of it and be able to bag it
