Street drug analysis / harm reduction

Melgar - 30-6-2017 at 03:32

I've been asked to help determine a cutting agent used in an illegal substance, that supposedly has odd effects on people who use it, and is very difficult to separate from mixtures. This could be all delusions in the minds of whoever's dumb enough to keep using this crap after it makes them loopy, but I've been presented with some compelling physical evidence and now I'm pretty curious myself. Apparently, people are divided over whether this is some brand new cutting agent that hasn't been seen before, or whether it's just an old one that's made a comeback, and it would be interesting to settle the matter somehow. I'm just not sure a) whether it would be safer to do preliminary analysis myself, or send a sample somewhere, b) where I might be able to send a sample that would be able to do a proton NMR test of a sample of an illegal substance, possibly containing a new cutting agent, and c) the legality of all of this. Supposedly, there are labs that test drugs for harm reduction purposes, but they may only work for known agents. I'd just as soon not have illegal (though heavily adulterated) substances in my less-than-neat lab, so my first choice would be some sort of third-party analysis. But I don't know where I'd start with that, or the legality of such things. Also unsure of payment, but that shouldn't be an issue.

Praxichys - 30-6-2017 at 05:25

I would try a preliminary analysis myself assuming you have a large enough sample size. I'd use disposable labware, do it somewhere else, and get rid of the whole kit once you're done.

What is the substance in question? It would help us to brainstorm what the agent might be and some presumptive tests for them.

JJay - 30-6-2017 at 06:38

The Department of Justice has developed a drug analysis kit and tables for numerous drugs and some other substances, documented here: https://www.ncjrs.gov/pdffiles1/nij/183258.pdf These are designed for field use. I haven't seen a full kit available to the public and it is not trivial to put one together, but it's not outrageously difficult either. Such a kit theoretically might be considered drug paraphernalia if found with drugs or if used for illegal purposes such as testing drugs before purchase, and local police policies may differ, but I think most tolerate and sometimes even promote genuine efforts towards harm reduction.

There are some books on organic qualitative analysis in the ScienceMadness library.


phlogiston - 30-6-2017 at 06:59

You don't state your location. In the unlikely case that the drug was purchased in the Netherlands, you can submit it for analysis here: https://www.drugs-test.nl/


Melgar - 30-6-2017 at 21:55

Ok, well the drug in question is methamphetamine, in the US. Supposedly, it originated in Mexico, and was also cut there. Rumor is that an agent was added to it to make it form large crystals more quickly and easily, and whatever this cutting agent is, they just kept increasing the amount of it, and according to the individual who requested my assistance with determining its identity (Let's call him "John Constantine". Like the movie/comic book.) the cutting agent has oddly specific symptoms. Apparently it makes people get "brain zaps" where they just blank out for a fraction of a second, it makes them feel sleepy immediately after using it, and it makes them act like heroin addicts, just blankly staring into space while they keep using it over and over, chasing a high that never comes. Apparently real meth addicts build shit out of spoons and old bicycle parts or whatever, they don't just sit there using it over and over.

So I did a bit of research and forums are full of meth users who claim they've been using for years and their tolerance just shot up, all at around the same time, a few months ago (February or March). Also, these forums are full of users claiming the exact same set of symptoms relayed to me by John, that they're experiencing from methamphetamine, but never have before. Since somehow this stuff cocrystallizes with methamphetamine HCl, or does something similar, it's nearly impossible to separate via recrystallization. Top contender for its identity is isopropylbenzylamine. Important things to notice: it's achiral, it has a benzyl group on the ammonia, and it's a structural isomer of methamphetamine, as well as a secondary amine like methamphetamine. I was trying to think of ways to cleave the benzyl group in a sample, then separation on the rest should be easy. That would prove at least that it's a benzylamine. If it isn't, then it's a total unknown, although it'd still be a secondary amine with a phenyl group somewhere in it, that gives no result to the marquis test.

JJay - 1-7-2017 at 00:20

Oh, umm... sounds shady.

You could probably use TLC to see if it matches isopropylbenzylamine.

^one of these guys will test it for you

I wouldn't bother trying to guess it if we don't at least know the drug and maybe a rough description of the effects. There are dozens of nerve cell surface receptors each with trillions of possible small molecule ligands.

Melgar - 1-7-2017 at 08:43

TLC and just about every other test is, as I'm told, nearly identical to methamphetamine due to their very close structural similarities, and the fact that they're structural isomers. I'm thinking that maybe the bitartrate salts might be better for making them more easily separated? In any case, I'm going to make sure I've synthesized isopropylbenzylamine at least, before agreeing to test any samples. Seems like the way to go would be benzaldehyde and isopropylamine, but I'm not really sure what to do about the isopropylamine. Hydroxylamine + acetone, then reduce? Or this patent that produces isopropyl sulfate from propylene and sulfuric acid? And complicating things further, there are other benzylamines too, like methyl and ethyl benzylamine, that are also used in the same way.

I guess the other option is benzyl chloride + hexamine, then delepine reaction to get benzylamine, but I've heard reductive aminations don't do well with acetone. Maybe isopropyl bromide + benzylamine then, since the resulting amine would be too sterically hindered to undergo a second isopropyl alkylation?

I'm not sure what your source is for that information, and you may well be correct, but according to a comment made here, that is not the case: https://www.reddit.com/r/DarkNetMarkets/comments/6dg76b/test... They're not that structurally similar.

I would think if cutting the stuff increases profits then by default a full kit available to the public would harm the illegal drug trade.

In the days of prohibition I bet water often got added to the booze as it was sold from person to person.

cabal - 2-7-2017 at 05:37

Hey Melgar,

I don't know where you're from, but in case you want a lab with proper setup test your sample, you could check out https://energycontrol.org/
If you're from Spain, they'll do it for free, if you're from abroad, it'll cost about 60 EUR, payable in BTC.

The problem you're desribing is interesting. When you said cutting agent to help make it crystallize, I immediately had to think about MSM, methylsulfonylmethane. It supposedly is added to methamphetamine to facilitate the growth of big glass-like shards. However, I don't know whether MSM would create any "brain zaps", although headaches and insomnia are listed as side effects when used as a dietary supplement.

Most of the time, meth gets cut with caffeine and amphetamine. But there's another possibility: how about a novel (or not well-known) research chemical? I remember reports of mephedrone and methcathinone being used as cutting agents for methamphetamine, or sometimes even outright sold as meth. In the past couple years, halogen-substituted amphetamines (like 4-FA) have become increasingly prominent, so maybe that's worth checking out.

I just looked up those "brain zaps" and found out that they are usually associated with MDMA. I have also found reports associated with antidepressants, specifically vilazodone. Some people alluded that this indicates a relationship between brain zaps and the serotonergic system. That would fit the bill for MMC and some haloamphetamines like para-bromoamphetamine.

All this just assuming that this isn't another urban legend that just spread among the drug user community, like they so often do.

curiosity_cat - 2-7-2017 at 10:39

I wonder if they are cutting it with those chemicals they called "bath salts" ? www.google.com/search?q=bath+salt+poisoning+symptoms

Pharmacologically, bath salts usually contain a cathinone, typically methylenedioxypyrovalerone (MDPV), methylone or mephedrone; however, the chemical composition varies widely and products labeled with the same name may also contain derivatives of pyrovalerone or pipradrol.
Bath salts (drug) - Wikipedia
https://en.wikipedia.org/wiki/Bath_salts_(drug)

What the heck is all that stuff, yuck !!! Could that be the "brain zap" crap ?

What the hell people, if you insist on doing amphetamines memorize the symptoms of ADHD and go to the doctor and have your heath insurance pay for it instead of killing yourself with this street crap.

curiosity_cat - 2-7-2017 at 10:46

www.google.com/search?q=wellbutrin+abuse


But I still think its that bath salt stuff or but also maybe that nasty crap they put in "pre workout" ? I read the label and it had those long chemical names that looked amphetamine like.

The marketing on that pre-workout give you jittery anxiety powder: Drink this crap that puts you at risk for heart issues then go out and exert yourself.

Before you workout you 'need' pre-workout... Just put enough ads in the muscle magazines and pictures of people on steroids and everyone will believe it.

Let me know If I solved the whats in the meth puzzle.

I missed this before. Brain zaps are a known side-effect of a little known class of drugs called SSRAs. In fact, a sudden tolerance buildup is also symptomatic of SSRAs -- not the drugs alone, but when combined with stimulants, they cause the brain to phosphorylate and internalize (destroy) its monoamine transporters, resulting in less activity for either drug. This receptor phosphorylation is part of the effects which contribute to post-MDMA-abuse depression syndromes. The SSRAs were initially introduced as MDMA substitutes, but discontinued due to a combination of disappointing primary effects and unpleasant side effects.

But, perhaps most notably, SSRAs provide extreme euphoria when combined with amphetamines, but only the first few times. If you use it the way a meth addict does, that euphoria soon gives way to anhedonia.

Anyway, SSRAs include IAP, IMP, MDAI, MDMAI, and 5-MAPB. It could be one of these, or something else like them. In particular, IAP and IMP have very similar chemistry to methamphetamine:

That user has later posts, where he says that it could be isopropylbenzylamine, although tests he did on it showed mixed results as to whether that's what it was. He also said that a lot of the information he was able to find on it was only anecdotal and probably not reliable. Sent him a PM there anyway to see if he has any new info.

To respond to a bunch of people at once: The aforementioned Mr. Constantine has been doing field research, interviewing people who have come across this stuff. Much of it DOES have bath salts in it, but those seem to have been added downstream, to compensate for the overall low purity of what middlemen were receiving. The prime contender still seems to be isopropylbenzylamine, which isn't especially psychoactive. However, a typical methamphetamine user will use perhaps a quarter of a gram in a day. If what they purchased is 75% isopropylbenzylamine, they're likely to use four times as much, meaning 750 mg of isopropylbenzylamine. That much of virtually any secondary monoamine seems all but certain to give people weird side effects.

I was thinking about the economics of it, and realized that if one entity was able to corner the market for a particular drug, it would then be to their benefit to deliberately vary the purity of it. They'd have to cycle between high and low purity, such that there isn't enough time during a low-purity cycle for a competitor to steal business from them. The cycle would have to be such that as soon as any competitor started to gain traction, markets would be flooded by high-quality dope again. By doing it this way, they could make a ton of money not just by selling fake drugs as real drugs, but because the users would actually buy MORE of the low-quality stuff because they'd need more in order to have any effects from it. It's kind of evil, but I guess that should be expected from groups that pile their enemies' torsos in public places as a warning.

arkoma - 3-7-2017 at 17:44

yep. Isopropylbenzylamine. "Speed" that comes with its own pillow. There is a report out of San Diego DEA documenting the fact that the cartels are actually packaging and smuggling it in just as it was true d-desoxyephedrine.

Characteristics:

The "rocks" are markedly softer than the real deal;
The "crackback" in a pipe noticeably (even when tweaked) different than real deal;
Shit stays CLEAR when smoked, never gets the brownish look of the real deal;
Makes you TIRED.

Marquis reagent is a damn good field test for it. With a little experience one can tell the extent of cutting by rate or lack of color change. Available inexpensively with color chart on eBay.

been googling trying to find that report and failing ATM but my brain is impaired a bit due to the opiates I am getting here in hospital. Think I have it somewhere on my HDD but that is needle/haystack thing too. If/when I find it will post.

Very good info

They are some association providing analysis depending of your country:

this spanish organisation can perfom a full analysis of anything for 70EUR
https://energycontrol-international.org/drug-testing-service...

If you want to try yourself, Clarke's Analysis of Drugs and Poisons 4th (ask on U2U) is a good source for chromatography analysis. https://www.reddit.com/r/ReagentTesting/wiki/nps page is a good compilation of sources too, and http://bunkpolice.com/browse/ that offer a big library of reagent testing result.

d-Methamphetamine hydrochloride - Melting Point = 172 - 174c

N-Isopropylbenzylamine hydrochloride - Melting Point = 192 - 193.3c


Has anybody got any ACCURATE solubility data for these two compounds.
All I could find was DCM and acetone.

I'd heard that they'd attempt to smuggle the isopropylbenzylamine in first, then send the real stuff in after it if the fake stuff got through okay. Then rather than just throw the fake stuff out, they'd use it to cut the real stuff to shit on the US side.

So, uh, what about tests that don't require me to smoke it? Assuming it's adulterated, that'd mean it'd give a melting point test indicative of a mixture, right? So like, according to Google, methamphetamine HCl has a melting point of 175˚C. I asked Constantine if he could do a melting point test, since that came up as a potential test last weekend. (He's several states away, at the moment.) He just got back to me and said it starts crystallizing at 160, and finishes at 150. So it's definitely cut, although we kind of knew that already. However, isopropylbenzylamine is supposed to have a significantly HIGHER melting point, so it's odd that a heavily-cut sample would have such a low melting point, assuming that's the cutting agent.

Quote:

The bunk would have to be at least 15-25% real, no? Just barely enough to make it better than nothing.

Quote:

It would be nice if there were tests there that didn't involve smoking it or injecting it. *shudder* Also, I don't have any pure methamphetamine to use as a standard to compare using tests like the Marquis test. Constantine claims that Marquis test shows "weak positive", whatever that means.

clearly_not_atara - 5-7-2017 at 09:07

Combining two different crystal structures would presumably increase disorder and thus lower the melting point. Methamphetamine and isopropylbenzylamine (if that's what it is) are not as similar as melamine and cyanuric acid that they would form a low-energy cocrystal; it's likely to be more like an alloy.

Quote:

Here's an idea: try hydrogenating the stuff over Pd/C. Isopropylbenzylamine should release isopropylamine and toluene, whereas methamphetamine should show no reaction.

Melgar,

I would be careful with this if I were you. I have heard that even purifying an illicit drug that you purchased can cause you to come away with manufacturing-like charges, so if you are performing bench work on a sample of an illegal compound, then it could make things more difficult for you, especially if you don't have the licenses required for said work.

This also presents the case that at some point in the future if someone ever does come to take a look at what you've got, they might be able to find trace amounts of the drug on your glassware or equipment.

Not worth it in my opinion.

Danger, Will Robinson!

Good advice.

the quickest, easiest ghetto ID on this shit is what dopeheads call "crackback". the recrystallization in the pipe.

Another thing I am curious about is why the interest in identifying this particular impurity? I am sure there are a multitude of compounds that could be used in this way that would produce the same effects biologically, so there isn't likely any novelty to the impurity. That would be the only reason I can find for interest in identifying it, other than the five finger exercise of going through the steps to separate and characterize it.

Bunkpolice.com says they will soon have anonymous qualitative analysis services available.

Now, "once upon a time" methamphetamine was made in the USA and the folks south of the border grew weed. In the last two decades this has COMPLETELY flip flopped. The American farmer has once again proven that we are the best and most productive farmers EVER. The cartels are business people and IMHO are interested in $ ONLY. Their product is either really high quality, or it is total shit. They don't cut their product. Isopropylbenzylamine is easy, easy money but it won't support an ongoing business model. 99% of tweakers don't have the skill to cut cartel dope and recrystallize. the IPBZA (tired of spelling it out) provides enough of a head change to momentarily pacify the monkey (on your back).

Have your buddies READ the OP in the link I provided above.

This thread has about run it's course methinks. Bluelight and Drugs-forum much more knowledgeable place to discuss this issue. In fact it has been extensively covered there as is HARM REDUCTION. Not advocating the restriction of "free speech" but this is a amateur SCIENCE forum.

Indeed, and I think this is about the fourth time someone in this thread has linked an anonymous drug testing service. These services are quite respected in harm reduction communities, and they generally have access to equipment that amateurs do not.

I hadn't thought about it, but Loptr's point is sound. It may not be wise to analyse street drugs in your home lab, especially if you, like Melgar, have always been an above-board chemist and do not take anti-government precautions the way a real drug chemist does. It would be very unfortunate for a ScienceMadness member to get prosecuted for a misunderstanding arising from this issue.

It's fun to talk about hydrogenolysing benzylamines, but not fun to get caught playing with meth.

[Edited on 5-7-2017 by clearly_not_atara]

Melgar - 5-7-2017 at 21:48

I wasn't so much interested in doing the analysis myself, as I was the idea of coming up with some simple way of testing and/or separating the substances, both for the purpose of harm reduction and because it seems like an interesting challenge. Since the chemistry discussion is orders of magnitude better here than on the forums you mentioned, and because it's the chemistry that I'm interested in, I posted the thread here, in the "Legal and Societal Issues" forum.

Hydrolyzing the benzylamine moiety was my first thought too, but then I realized that if someone just made a different salt that wasn't the hydrochloride salt, solubility could be vastly different. I'm pretty sure Constantine doesn't have a hydrogenator or Pd/C catalyst, but he can probably get tartaric acid, and make the bitartrate salt.

I also am interested in this, because I can just toss ideas to my friend, and then he does the experimental work. Apparently wherever he is in the Appalachian region, methamphetamine is like the social thing to do there. He says this stuff makes him feel like shit and he won't touch it. Not really sure why he's still there though. Sounds like there's not much to do besides fuck around trying to clean cut meth.

JJay - 6-7-2017 at 00:05

Everyone who regularly reads this forum knows that Melgar isn't making drugs in his garage. But a casual observer might not know that.

Bitartrate seems like kind of an odd choice unless you're dealing with a racemic mixture, but if you know that bitartrate salts of D-meth and L-meth have different properties and that the substance in question has similar properties to meth (which seems odd given its structural differences), it might not be an entirely unreasonable choice. But IMHO, despite claims to the contrary, you can probably resolve this issue by going to the library without ever looking at any meth.

I'd suggest playing with something legal that does neat color changes, or pyrotechnics.

The advantages of Appalachia are that it's pretty and (in the southern parts) the climate is mild, with cooler summers than the lowlands and winters that aren't much worse (excluding coasts, which have the best winters). For example, Asheville's July and January average highs are 84 and 47, whereas for Memphis it's 92 and 50. For Cincinnati, that's 86 and 39. Morgantown, to the east, sees 83 and 39, with 12 days per year above 90 compared to Cincinnati's 21.

The disadvantages are... well... roughly everything else.

Praxichys - 7-7-2017 at 10:03

I would try a couple of things.

First, elute with TLC plates and see if you can separate anything out. Odds are you won't be able to chirally resolve the amphetamines on silica but the suspected cutting agent will separate with the correct choice of solvent. You will probably have to freebase the sample first and play with solvent mixtures to get a clean separation. TLC is easy and cheap though, and amphetamine should be easy to develop with iodine vapor or with weak permanganate solution and a little heat.

Once you have determined the r-factors, scale up. Use a packed column and the same solvent mixture to get a physical gram-scale sample of the adulterant. After isolation, you will be able to assay the MP, BP (if applicable) crystal structure, density, and get molecular weight from freezing point depression in a suitable solvent (or using the Dumas method assuming no decomposition). A cheap polarimeter or close examination of crystals can tell you if the adulterant is chiral. Titrimetry will confirm if it's monobasic or not. You can find out if it's deliquescent or if it forms hydrates by checking mass loss with gentle warming in a vacuum desiccator or with a dean-stark setup. That should give you enough clues to find out what it is from published references, or at least distinguish it from a set of common adulterants.

To further confirm, you could get a sample of isopropylbenzylamine and subject it to the same tests. See if it elutes identically, etc.

Another question would be how heavy of a drug user is your friend? I was prescribed adderall for my ADD type-3 diagnosis when I was 5 years old, and after being on it for about 20 years I started getting paradoxical effects. I would take it and immediately fall asleep. It was bizarre. I eventually stopped taking stimulant medications because I realized it was probably time to find another form of treatment.

Could these issues you described actually be subjective effects?

So how does this help in analysis? This is just a subjective report, but does it help in accurately descrbe an impurity? I think that even heavy stimulant users won´t endure a 20 year binge, usually they loose interest after estimatedly seven years.

I was prescribed adderall for my ADD type-3 diagnosis when I was 5 years old, and after being on it for about 20 years I started getting paradoxical effects. I would take it and immediately fall asleep. It was bizarre. I eventually stopped taking stimulant medications because I realized it was probably time to find another form of treatment.

Could these issues you described actually be subjective effects?

So how does this help in analysis? This is just a subjective report, but does it help in accurately descrbe an impurity? I think that even heavy stimulant users won´t endure a 20 year binge, usually they loose interest after estimatedly seven years.


Well, my point is the possibility of the "adulterant" being the effect of changed biochemistry after sustained usage. If it doesn't act like a stimulant any longer, and instead puts him to sleep, then this adulterant sounds very similar to my experiences with adderal, which was a prescription, and had no significant impurities.

The point is that you can't trust any subjective experience or report. This might just be in the head of the drug user, and not in the drug they are taking. Granted, it is almost guaranteed to be cut with something, but that's beside the point. The effects the drug user is describing cannot be expected to only be attributed to this supposed impurity.

As a side note, it looks like Oregon is legalizing LSD, MDMA, cocaine, meth, oxycodone, and heroin: http://www.zerohedge.com/news/2017-07-11/oregon-legislature-...

I think there is still a small chance that the bill could be vetoed and the veto not overridden, but it will probably be signed into law.

Legalizing and Decriminalizing are very different things. The Oregon bill only proposes to "[reduce] possession of illegal drugs to misdemeanors rather than felonies as long as the person in possession does not have prior drug convictions."
The drugs remain illegal, as they should be. Meth in particular has done horrible things to the people in my area.

You're right... there are several articles online stating that there are no criminal charges to be filed for those six substances unless the offender has prior convictions (such as this one: https://libertarianvindicator.com/2017/07/10/hard-drugs-to-b...), but the actual bill does specify that possession of those substances is a misdemeanor.

He doesn't have enough income to be a habitual user, and when he runs out, he just gets a lot lazier than usual for a while. When he's not using anything he's kind of hyperactive. Really, he would almost certainly be diagnosed with ADHD by a psychiatrist if he actually went to one. He was a Navy technician for five years, so I've been urging him to just get an Adderall prescription through the VA or something. Maybe he will eventually, who knows. But he doesn't trust institutions at all, so I haven't made any progress on that front.

And yes, even though most anecdotes are regarding its effects on people, I'd obviously prefer to disregard them entirely in favor of more objective tests. Marquis test seems to be a good one. Constantine reports that the cut apparently inhibits the reaction between methamphetamine and the Marquis test, so that seems like an extremely easy test right there. And the Marquis test can be made just by adding some polyoxymethylene plastic to sulfuric acid, then waiting until it smells strongly of formaldehyde.

So it looks like there's finally an answer to this. Apparently, Mexican cartels have been diverting pseudoephedrine from the plants where they make it in India. I figured they'd have some more sophisticated method, but nope, they start with the same shit that trailer parks use. So the plants in India have cracked down hard on diversion lately, and the cartels have been forced to moved to a phenylacetone-based synthesis. But this produces racemic methamphetamine, and doesn't form huge crystals that people have come to expect. So they cut it even further with n-isopropylbenzylamine, which seems to have a whole mess of unpleasant negative side-effects like headache and lethargy. Since n-isopropylbenzylamine is achiral, it forms giant clear crystals like nobody's business, and incorporates methamphetamine into its crystals too.

It's basically what all the large-scale manufacturers have started doing now. All someone has to do now is develop both lung cancer and a stereoselective method of phenylacetone reductive amination, wage a turf war with the Mexican cartels, name himself after a famous mid-20th-century physicist, and recruit a delinquent former acquaintance as an assistant, and you'd have the setup for a really compelling dramatic TV series. :P

Pseudoephedrine is the ideal starting material because it's already racemically pure. Laevomethamphetamine is inactive, and while some people claim the racemate is more pleasant, it's nonetheless less potent, and potency = profit. Reduction of pseudo gives pure d-meth, whereas reductive amination of P2P gives a racemate. The only "total synthesis" that can compete is based on amateur biomanufacturing to produce a chiral precursor I won't name, which is then reductively aminated to produce... you guessed it, pseudoephedrine.

I suppose you could use a chiral catalyst for the reductive amination. There is a big phenyl ring to latch on to. But you're probably not making it yourself, so there's still diversion involved, and now you have to divert it from more sophisticated manufacturers who are less corrupt than... well, most of Asia.

Racemically pure, that's a good one... Even though we're talking about a compound which is diastereomeric. Are you talking about the phenylglycidate route being based on "biomanufacturing"? Or some derivative of mandelic acid I am unaware of? I've not heard of any amphetamine precursors being made by biomanufacturing.

I think that was just a brain fart and he meant "enantiomerically pure". The precursor is phenylacetylcarbinol, produced by fermenting benzaldehyde.
