Nor even the old pros can navigate the crap that is cocaine. So here is what I know about it currently. Much of the blow that everyone thinks is the kind because it was chipped off a brick is untouched. Fine, but at the first leaf extraction, using sulfuric acid, much more than cocaine is extracted. Cocamine and a few other alkaloids are extracted. Also plenty of oils and wakes. So, if your blow is yellow, it's a non active but rather heavy oil that will eventually solidify. If your candy smells of dirty gym socks or dust then it has an alkaloid in it that can be as much as 30 percent of the whole. Now not only is this stuff not cocaine but it actually has a sleepy, mentally dulling effect. As the acid sits with the leaves, it tends to extract other things, as I said. Now who would not like a heavier yield? You are likely a farmer getting the pasta to market and you don't care about purity, the lab upstream will do that, right? Well, way back then they did but not now. In the old boutique days, the cocaine and all those alkaloids were dissolved in water and treated with a strong oxidizer like potassium permanganate. It would attack everything but cocaine. At first, but depending on time, temperature, and ratio, the potassium permanganate would start destroying the cocaine as well. No one who makes about the same amount of money regardless of the relative purity of their product is going to first, reduce the total weight and then, actually destroy some if the active ingredient. So, they don't try. That is why purity at the brick is so random.
It is entirely possible that a solvent free, never cut cocaine from that brick is no more than 70 percent hydrochloride. Now these guys may not care about purity but they know that everyone thinks that fish scale, pearlescent flake draws the experienced buyer like moths to a bug zapper. they also have a hard time crystalizing this low purity Chemical.
In comes the lavamosole. Folks who do this for a living understand basic economics. Why would they lay a legal cut on a product before it is smuggled ? They pay by the pound, or if they are moving it themselves, then they deal with bulk and size. So you don't pay to smuggle something you don't have to. But this Chemical is so much similar to cocaine that it raises the apparent (don't take this to the bank) purity enough to bring back those flakes. Now, furthermore, this stuff needs to be bonded, not just sprinkled in like one would most cuts so it has to be in the chemical processing.
Next, most organizations cannot get large quantities of good anhydrous solvents needed to thourougly wash their product. So they don't. This absence of a final wash will leave oils and waxes. that final wash is the one that takes out the yellow or the cream color and it means that your blow is even less pure.
Im guessing as much as another five or six percent crap in your nose candy. after it is done That could be as little as 65 percent pure. And then, maybe some clown buys his quarter pound, figures what he got MUST be 90 percent and cuts it with whatever. . but the main thing I am getting at is that even the stuff "right from the brick" has no guarantee of purity regardless of the lavamosole. And also, my suggestion baring chemical analysis is to ignore those beautiful flakes for the harder, amorphous rocks. You wont be buying as much solvent weight and you might be avoiding the only cut that most manufacturers are laying into their product at the source.
