Yes, because it contains racemic methamphetamine, so will test positive for that. However, there is one test that this concoction can't fool: the melting point test.
Get a stainless steel digital thermometer from Harbor Freight or Autozone or whatever. They're like $5. Make sure they can measure past 200°C. Then put a bunch of your shit in a vial, using a double-boiler type setup, with some kind of oil in the outer container. Vegetable oil, mineral oil, motor oil, baby oil, whatever. Anyway, heat the oil, which will then heat the vial, and its contents will melt. Insert the thermometer, and make sure the vial contents are completely melted. Then remove the outer vessel (with hot oil in it) from the heat.
Everything will cool down very gradually. Watch the thermometer, and watch for crystals forming in the inner vial. As soon as a crystal forms, take note of the temperature. More and more crystals will form. If you have real meth, the temperature will hold during this process, at somewhere between 170°C and 175°C. The temperature will barely change during the crystallization. It might fall 1-2°C, due to minor impurities, but the less it changes temperature, the purer you can expect it to be.
But since that's not something that anyone has these days, you can probably expect crystals to start forming at maybe 160°C, and for the temperature to drop maybe 10°C before it's all solid. This proves that you have a mixture on your hands, not a pure substance. This is the best way to test this shit by far, since there's absolutely no room for interpretation.
The ghetto version of this is "crackback", where users watch how the molten salt solidifies. If it solidifies in a wave, starting from one or two points and radiating outward, that indicates purity. If it forms slushy crystals around the edges first, and leaves a liquid pool in the center that emits vapors as it solidifies, then that means you have a mixture, and not a pure substance.
This "crackback" nonsense is like reading tea leaves
People assume that "crackback" means looking at the patterns in the solidified substance. That's wrong. Actual "crackback" means observing how the molten salt transitions from liquid to solid as it cools. You have to watch it in real time. While it may not be scientific, per se, it's actually a pretty useful observation.
There are plenty of other observations that are useful for identifying it. This n-iso concoction crystallizes in plates, whereas real d-meth crystallizes in shards. So when crystals crack, they often have plate-like surfaces visible. This makes it pretty easy to recognize once you have some experience.
If this were a mixture, you could separate the components by recrystallization
Yeah, if the meth was d-meth. But since you have both isomers, that greatly impairs their ability to form crystals, so instead it gets incorporated into the n-iso crystals. Levo meth can form crystals with other levo meth, and dextro meth forms crystals with itself too. Think of them like those zigzag shape pieces in Tetris. One is a mirror image of the other, and if you got just one or the other, you could stack them easily. But if you have both coming at you, it's a lot harder to stack them in nice solid shapes. That's why it gets incorporated into n-iso crystals instead.
But meth chemists couldn't have figured all this out! They don't know a damn thing about crystal lattices!
They learn by trial and error, mostly. And all they would have had to do is try combining n-iso with racemic meth, and letting it crystallize.
You don't know anything about chemistry and used the wrong word somewhere, therefore this invalidates everything else you've said
I'm sorry you feel that way.
What do you mean, "organized"? Coming up with conspiracy theories like that is a sign you need to lay off the pipe.
Yes, meth users are known for being paranoid and coming up with crazy conspiracy theories, but they don't tend to all point in the same direction, and start at the same time. This shit began in full force at some point in early 2017, and has remained consistent ever since. Thousands of anecdotes scattered all over the internet, all describing the same symptoms starting at roughly the same time.
It's not crazy talk. It's real. And we need to start treating this problem with the appropriate level of seriousness, unless we want to keep funding these cartels that are poisoning people.
I've tried to provide the best harm-reduction information I possibly can, but there's so much misinformation out there that it can be hard to sort truth from nonsense. So it's really important that we take on this misinformation that keeps being spread about what's going on. They think you're stupid enough to believe their bullshit. Prove them wrong.
