Fentanyl or Not? Re-analysis of Samples #5776 and #5779

As covered last week in Fentanyl Test Strips, Hot Spots, and Unhomogenized Samples, two samples reported in the November 6, 2017 batch of EcstasyData results were submitted to the lab with notes by the senders saying they had used fentanyl field tests on their sample before sending it.

The original GC/MS results for these samples (#5776 and #5779) did not reveal fentanyl. After writing about the problems associated with non-homogeneous samples and “hot spots”, we decided to use this as an opportunity to re-test both of these samples. This time, we used up 100% of what was sent by dissolving all of the sample (and not just a small portion), to make sure not to miss any potential “hot spots” in the original. That is a different method than our normal sampling protocol, meant to verify the no-fentanyl results.

On November 12, the lab reported back that the re-analysis of one of the samples returned a different result than the original analysis. The other sample’s result did not change.

Re-tested Using Modified Sample Prep Method

With most EcstasyData samples, there is material left over after an analysis. Whatever is not destroyed in the GC/MS process is stored for secure disposal after one year. This permits the lab to re-test a sample, potentially several times, if circumstances call for a re-test.

A modified method was used to re-test samples #5776 and #5779: For each of the re-tests, all the material, including the capsule, that was left over after the original analysis was placed in solvent to produce a consistent liquid sample, which was then run through the normal GC/MS process. This eliminated the “sub-sample of a sub-sample” condition that we described in the previous article.

Heroin Sample 5779: Positive fentanyl test-strip confirmed by GC/MS

The sample whose result did change after re-analysis was a powder represented as heroin.

The person who submitted the sample had noted the ‘Sample tested positive on both ‘DanceSafe’ and another brand of Fentanyl test strips (or cassette / dip card). Would like to know if these immunoassay fentanyl tests actually work.’ While the first GC/MS analysis did not detect fentanyl (even though a lot of the material was prepped for testing and the sample appeared homogenous), the second analysis that followed the method above did detect fentanyl.

This discrepancy in results can most likely be attributed to a hot spot or spots in the powder.

The lab also identified several other substances that they did not report in the first analysis: trace amounts of codeine, 4-ANPP, papaverine, and very small amounts of actylecodeine and 6-monoacetylmorphine. The additional very small findings are normal minor components of poorly-cleaned heroin produced from natural poppy resin. When we re-test a sample looking for very potent substances like fentanyl, we take a closer look at the trace and near-trace tiny “noise” bumps in the GC readouts.

Although we do report trace substances in most cases, street heroin is a good example of the type of material that often contains a lot of “noise” because it’s not pure, nor is it a combination of drugs; it’s a partially-synthesized natural product with lots of leftovers.

Because of the issue of fentanyl and fentanyl analogs showing up in heroin, EcstasyData has obtained a number of NPS-fentanyl analog standards and will be taking extra care to look for them in future heroin and opioid samples. Please include on your submission forms if you have concerns about fentanyl in your sample so the lab tech knows to look at what we normally consider “noise” in messy samples, and to set up the Gas Chromatograph run so that we make sure he can differentiate noise from signal at the time points where fentanyl and the known fentanyl analogs come out of the column.

MDMA Sample 5776: False-positive fentanyl test-strip

The sample whose result did not change with re-analysis was for a powder represented as MDMA. Only MDMA, with no traces of fentanyl or other compounds, was detected using the method described above. The person who submitted the sample had noted a ‘strip test tested positive for Fentanyl’ prior to sending their sample in. This strip-test result was not confirmed by GC/MS.

Evolving and Improving Procedures

Although we run one of the best analytical projects of its kind in the world, this is a great example of the many types of errors and misses that can occur, and we take steps like those described here, to verify our results and change our procedures to improve the accuracy over time.

Fentanyl Test Strips, Hot Spots, and Unhomogenized Samples

With fentanyl and fentanyl analogs haunting the opioid crisis in North America, some harm reduction field workers and users have been experimenting with what cost-effective reagent-based field tests might have to offer. One method that has been explored is the repurposed fentanyl urinalysis test-strip, where rather than dipping the test-strip in urine, it is dipped in a solution of the drug itself. A panel presentation covering the topic of drug checking and the opioid crisis was held at Drug Policy Alliance’s 2017 Reform Conference.

Since two samples included in the November 6, 2017 batch of EcstasyData results came with notes saying the sender had used a fentanyl test-strip on their sample before sending it, we’re starting to look at what that means for how we report EcstasyData results in such cases.

The question was posed by one sender,  “Would like to know if these immunoassay fentanyl tests actually work.” Like many Yes/No questions that people have about drug analysis, the answer is a combination of “it depends” and “it’s complicated”.

Hot Spots
In answering the question, it helps to remember that not all powders will be completely evenly homogenized and may contain “hot spots” with uneven concentrations of a given chemical in sub-parts of the larger amount of powder or crushed crystalline material.

Powders and tablets that have more than one component to them aren’t always evenly mixed. Sometimes there’s a higher concentration of a drug in one or several areas. Think of a burrito that has hot salsa in one end of the burrito but not the other. If you bite into the burrito on one end, it’s spicy. On the other end, it’s not. Or a chocolate chip cookie — the chocolate chips might not be evenly distributed in the cookie. We’ve discussed homogenization in EcstasyData samples before when talking about traces of drugs in samples sent to the lab.

Hot spots are a bigger deal when it comes to fentanyl drugs or other similarly potent drugs, that are active at doses below a milligram but are sold in powders weighing hundreds of milligrams or grams.

Sub-samples of Sub-samples
When a powder sample is received by the EcstasyData lab, the lab tech preparing it for analysis first does a very simple partial homogenization by shaking the sample container or stirring it a little before extracting a sub-sample with a clean metal or plastic spoon. The sub-sample is then dissolved in a solvent and the technician confirms that the material dissolves completely or may take additional steps to get a fully dissolved, consistent liquid sample.

The dissolved sub-sample is then inserted into the testing equipment (the GC/MS). If fentanyl is present in that solution, then fentanyl will show up on the test, and we report it. If fentanyl is only present in a part of the sample that was not dissolved into solution, the fentanyl can not be detected.

So there are at least two steps of sub-sampling that occur before a tiny amount of material reaches the GC/MS:
1) The sender takes a sub-sample out of their stash/bag/jar at home and sends it to the lab.
2) The lab tech takes a sub-sample of that sub-sample to dissolve and inject into the GC/MS.

Someone using test-strips on powders or tablets at home is facing a similar issue of potential hot spots.

Can’t Be Sure
If a fentanyl test-strip is used to check a drug sample and the result is consistent with the presence of fentanyl (a so-called “positive”), there are several possible explanations, some including fentanyl being present, and some where there is not fentanyl present (“false positive”). A test-strip can also be difficult to read.

Some Positives are False Positives
A positive result with a test-strip can mean fentanyl is present in the sample, either deliberately, or by contamination. Tablets might have come into contact with the substance and have a tiny residue left that could trigger a positive field test.

An unknown and unknowable number of other conditions can cause false positives on urine drug screen strip-tests. Non-fentanyl drugs might trigger the field test to show positive. The problem of false positives is the reason urine strip-tests alone are insufficient to prove someone has taken a given drug in legal or employment contexts. Positives from urine screens are always double checked using an advanced technique such as GC/MS to confirm or exclude the simpler, cheaper strip test.

Test-Strip Outcome Can Be Hard to Interpret
Test-strips and other field tests often have a wide range of possible strengths of color changes. It is common to get results that are not 100% clear in what they mean.

EcstasyData can’t comment on whether fentanyl test-strips in general are useful in detecting fentanyl in drug samples. Each situation is unique.

We are keeping an eye on this topic.

PS: In August 2017, Erowid confirmed that the DanceSafe fentanyl test strips give false positives for buprenorphine. When mixed at a concentration of .01mg per ml water. We have another draft post that hasn’t seen proper review yet that goes over this in detail.

Lab Drug Checking and Positional Isomers: 2-, 3-, or 4-MEC

This last week, a sample was submitted and analyzed through EcstasyData that we clearly established was one of the three main ring-positional isomers of Methylethylcathinone (aka MEC). However, we didn’t have the lab standards on hand for this chemical, because it is the first time we’ve run into it since the supplier of lab standards we order from has stocked the three positional isomers.

Based on library matches* alone, it was impossible to be certain whether the sample contained 2-MEC, 3-MEC, or 4-MEC. We’ve run into this issue of positional isomers a bunch of times before over the last sixteen years of operating our street drug analysis project.

Luckily, Cayman Chemicals is a really great source of lab standards for NPS (“new psychoactive substances” aka psychoactive research chemicals). So we ordered reference standards for 2-MEC, 3-MEC, and 4-MEC, to find out if our equipment and lab procedures could make use of having the actual verified isomers on hand, for the purpose of confirming whether sample #5682 contained one or more of these slightly different versions of the same parent compound.

We ordered the standards on September 5th and they arrived at Drug Detection Laboratories (the lab that EcstasyData contracts with) on the 7th. The amazing DDL lab team, working on Saturday, ran the standards through their GC/MS and were able to confirm that sample #5682 contains only 4-Methylethylcathinone and none of the other two positional isomers. Yay!

There are many psychoactive chemicals with positional isomers that are difficult to reliably differentiate using GC/MS or UV absorption, even with the proper standards on hand. We’ve spent a lot of time over the last few years seeking clarity in our analysis of fluorinated amphetamines (2-, 3-, or 4-Fluoroamphetamine aka 4-FA) and the *-APB chemicals. And we’ve not been entirely successful. In most cases, one of the positional isomers is easy to tell apart from the others, but the other versions overlap in complex ways by retention time or fragmentation patterns. For MEC, the differences in column retention times for each of the positional isomers make them easy to differentiate using DDL’s Agilent GC/MS.

On another note, we also ordered a lab standard for Benzyl fentanyl this week, and were able to confirm that sample #5667 contains only Benzyl fentanyl. Less impressive, since we were pretty certain that’s what it was to begin with, but the initial match was based on comparing against other published spectra and not our own lab’s confirmation using a known standard of the same substance.

Notes

*Identifying “by library match” refers to the process of comparing images of GC/MS output for a given sample to images of GC/MS output for a verified reference standard. Because equipment and lab procedures vary, to double-check identification by library match, a lab can acquire its own sample of a reference standard (if one is available), run it through the lab’s equipment, and compare the resulting images to those of the submitted sample being analyzed.

International Drug Checking Day – Mar 31, 2017

Erowid is supporting the new International Day of Drug Checking, an initiative by a diverse group of organizations playing active parts in the delivery of harm reduction services.

On the 31st of March we celebrate and raise awareness of drug checking. Here we mean not only the testing of substances; Drug Checking Day serves as a reminder for people to make a habit of testing their knowledge about drugs and their effects. We remind people that taking any drug always comes with risks, as does all human activity. By raising awareness and sharing knowledge, partners in International Day of Drug Checking hope to improve awareness of ways in which each individual and every community can reduce health risks.

Why International Drug Checking Day?

Drug checking is a sound harm reduction approach and we believe more people should have the opportunity to test their drugs so they can make informed choices and reduce risk. Full chemical analysis of substances through GC/MS (Gas Chromatography/Mass Spectrometry), TLC (Thin Layer Chromatography), HP-TLC (High Performance Thin Layer Chromatrography), or infra-red methods is the best way to find out what is really in a substance. Seeking services of drug checking groups offers the best opportunity to connect with a professional who can offer expert harm reduction information. There is a 30 year history of drug checking in Europe with well-established test services in the Netherlands, Spain, Portugal, Switzerland, Germany and France. Testing on-site at festivals has also begun in the UK. Drug checking programs in the United States date back to the 1960s.

International Drug Checking Day is also raising awareness about how people can check their drugs at home using reagent test kits. These can be bought online and can give a good indication of what a substance might be. While we recognize there are limitations to using reagents we still believe this is a great way to reduce risk and an essential way to introduce people to finding out more about harm reduction.

A Right To Know — A Right to Drug Testing

It is Erowid’s stance that individuals should have a right to know what substances they are putting in their bodies, and thus, a right to access accurate, quantitative analysis of the drugs they might ingest. People should be appalled that their governments want to discourage citizens from choosing to use disapproved drugs because they fear toxic adulteration and dangerous substitutions.

Drug use is a global phenomenon. Many people around the world ingest some kind of substance on a daily basis, from caffeine to alcohol, cocaine to heroin. Drug use has become a moral and criminal issue with legislation and regulations generally following a global model of prohibition. Prohibition has led to networks of underground markets, with drugs being purchased on street corners, private homes, and through the internet.

These clandestine markets are unregulated, with no consistent oversight or product verification, which is known to cause increased and unnecessary risks. Quality control standards may be in place at some labs producing illicit drugs, but not others. But once these products are picked up by distribution networks, any certainty of identity or quality is lost, without independent drug checking. There are no standard dosage units, no list of ingredients and no information leaflet about possible side effects, interactions or ways to minimize risk from use included with these products. Similarly, online pharmacies operate in legal grey zones that raise the risks of unregulated medicines reaching the public.

We know that drugs that are sold in grey and black markets are sometimes substituted, mislabeled, or contaminated. Adulterants may be used to mimic the effects of more expensive drugs and while some may be fairly benign, others can produce toxic and fatal results. Global fatalities from drug use are rising, primarily because of the opioid epidemic, while the dynamic drugs market is becoming ever more fluid in response to legislative developments that attempt to limit the proliferation of New Psychoactive Substances (NPS). Avoidable fatalities from unregulated and under-regulated drug distribution are an unfortunate part of the world, one that we can work toward trying to mitigate through drug checking.

People who take drugs recreationally or who use pharmaceuticals from less reputable sources are at increased risk of harm through consumption of pills and powders with unexpected or unknown ingredients. While the use of any drug is not entirely risk-free, having an awareness of the chemicals contained can help people make informed choices about what they might put in their bodies, and help them to plan dosage and minimize the impact of use on their general wellbeing.

On-Site Drug Checking: Reagents, Methods, Harm Reduction, and Politics

On January 20th, The Sydney Morning Herald published “Pill testing sounds like a great idea, but there’s a catch”, by forensic toxicologist Andrew Leibie, who reasoned that field testing is not very helpful, and might be worse than nothing. Leibie seemed to both not understand what he was talking about, and to ignore some of the key benefits of having on-site testing at events where illegal drugs might be consumed.

A few days later, Monica Barratt responded with a critique of Leibie’s flawed article. In “Pill testing is still a great idea, if we use the right equipment”, she took Leibie to task for his assembling a series of partially true statements into a confused and ultimately wrong argument.

I have some points I want to repeat and add, since this is something we care (and know) a lot about.

Engaging Users

First, let me just be clear about a critical function of on-site drug checking: engaging people is the most important step in harm reduction. Once people start thinking about and taking steps to mitigate the risks they expose themselves to, everything else is gravy. Leibie argues from confused and incomplete data that on-site pill testing is ineffective and may be worse than nothing. For example, he strangely compares rates of deaths from new psychoactive substances (NPS) in the UK to those in Australia, and uses the comparison to imply on-site pill testing doesn’t reduce harm.

Reducing Harm, Not Eliminating Harm

Second, to paraphrase one of our colleagues: “It’s not about eliminating harm, it’s about reducing it. Taking drugs, like every other activity in life, is never ‘safe’.”

On-Site Testing Is Not Just Done with Reagents

Third, it’s key to understand that on-site drug checking, what we might call “field testing”, can span a wide range of different methods. The most common are reagent tests like Marquis, Mecke, Simons, etc. These are simple “rule-in / rule-out” tests. Liquids are dropped onto scrapings or dust from a sample and may or may not change color. To a person experienced in the use of reagents tests, the color and timing can tell a lot about a sample. What reagents tests can’t do is positively identify anything.

They rule chemicals in and rule them out. If a pill shaving has Marquis reagent applied to it and there is no color change, then it is almost guaranteed that the sample contains, at most, a tiny trace of MDMA. MDMA is ruled out. If the sample + Marquis changes to a dark purple-then-brown color, then MDMA is “ruled in”. This means simply that the reagent reaction is consistent with MDMA and not, as some believe (including some law enforcement personnel trained to use these field tests), that the sample has been shown conclusively to contain MDMA.

There are an unknowable number of different reasons why the Marquis + sample could change color to the typical dark purple/blue/brown. The presence of certain dyes in a sample, temperature, a reagent past its “best by” date, opioids, and potentially yet-unknown other chemicals can produce that color when a sample comes in contact with Marquis. All we can say is, if there’s a color change consistent with how MDMA would react, MDMA is ruled in as a possibility.

Better Guesses are Better

Or, in Leibie’s mischaracterization, “the proposed colourimetric on-site pill test kits provide results that are little more accurate than ‘best guesses’.”

There are a couple things wrong with the wording of Leibie’s assessment of colorimetric field reagent testing. First, “best guess” is obviously better than a bad guess. Second, in every case I can think of, the use of a reagent test would be preferable to not using a reagent test at all. The color changes are informative but not final proof. They are definitely more relevant than a “best guess” made in the absence of any drug checking methodology.

But back to the bigger error: Leibie seems to conflate on-site pill checking with field reagent testing and then draw conclusions that are out of step with current trends. A growing number of groups are using much more interesting and accurate methods to analyze and identify drugs on location at events and festivals.

European On-Site Analysis

Groups like Austria’s CheckIt!, one of the partners in our EcstasyData lab analysis project, don’t “guess”. They run a mobile HPLC-MS unit, optimized to function reliably in party settings, and use it on-site at events to do accurate identification and quantification.

Energy Control in Spain has developed procedures for using Thin Layer Chromatography (TLC) on-site, in hot and dusty tents at mega festivals. Their methodology and expertise make it possible to not only identify drugs but to get approximate quantification as well.

There are groups using mobile FTIR (Fourier transform infrared spectroscopy). FTIR has been around a long time, although as an on-site drug checking method it’s very new. FTIR is definitely capable of more than a “guess”. FTIR has a long history as a lab technique, returns results rapidly, and involves equipment small enough to potentially be workable for mobile on-site setups. FTIR can be used to positively identify chemicals and is considered a proper forensic lab method for identifying street drugs.

Near Future: Cheap Portable Spectroscopy

The utility of portable infrared or Raman spectroscopy in on-site drug checking is on the near horizon. Raman, IR, UV, and other absorption or back-scatter analytical technologies work by shooting a laser source at a sample and then reading the patterns of reflected or transmitted light and comparing that against a database of known patterns. In the next ten years, it is likely that the costs of these portable devices could drop below $500 per unit, and the databases of patterns could be extensive. Not quite ready for real world use, but… not too far away either.

On-Site Drug Checking Blocked, Banned, & Political

The primary reason these lab-grade testing methods aren’t more widespread is that the politics of drug checking are super horrid. There are critics, like Leibie, who are just confused about the usefulness and harm reduction aspects, but the much bigger problem is the world governments dominated by prohibitionist thinking. Prohibitionists actually argue that it is a bad idea to “make drug use safer” and provide “quality control for the black market”. In this very common paradigm, the goal is to make illegal drug use as physically risky as possible rather than trying to reduce the potential damage done to people.

From my perspective that’s wholly unethical and policies based on pretending people will never take MDMA and other psychoactives are not only delusional, they are mean-spirited and unjust. But that’s the world we live in.

In most countries, harm reduction work is hamstrung by the fact that it is illegal (as in go to jail) to provide accurate drug checking. It is also disallowed because event producers do not want to be perceived as “pro-drug” or possibly be held accountable for drug sales or use at their events if they’ve acknowledged that it occurs. Inviting a harm reduction team with a bunch of equipment to operate at a party is de facto condoning illegal drug use, or so goes the thinking.

The Real World: Field Reagents Better than Nothing

So, despite the viable options for offering high-quality analysis at large events, what we are often left with is young harm reduction workers equipped with small bottles of field reagents such as Marquis. Reagent tests don’t cost very much, they are affordable enough for it to be OK if they’re seized or destroyed by law enforcement, and the number one purpose for using them is still served: Engaging with people about the fact that there are risks to taking illegal drugs, that one can have a rational relationship to those risks, and the worst and most likely of those risks can be reduced with sufficient knowledge, some foresight, some help, and a little care.


Now, on to an examination of other weaknesses in Leibie’s piece:

MDMA Is Not “Often Fatal”

Leibie statement: “High doses of MDMA and methamphetamine are often fatal by themselves.”

Risks from high dose MDMA tablets are explicitly acknowledged through social media marketing methods, such as Global Drug Survey and Mixmag’s public health message, “Don’t Be Daft / Start with Half” (UK).

That sentence is deceptive because of the word “often”. Water is a deadly poison. A high dose of water is often fatal by itself. Aspirin is a deadly poison. A high (enough) dose of aspirin is often fatal by itself. Leibie properly points out that MDMA and meth, even when they are of known quality and quantity, are not totally safe. And there are cases of people doing reasonable doses and still dying. But those cases are extremely rare. There is little evidence that people frequently die from taking MDMA or methamphetamine that is higher in potency than they expected.

Some tablets sold in Europe contain over 200mg of MDMA, a startlingly high dose. A small woman taking that amount of MDMA could be taking a serious risk, but the chances of her dying because on-site pill checking failed to give her clear quantitative information are nearly zero. It is very likely, in fact, that if the woman in this scenario visited a harm reduction table and asked about the tablet she was thinking of taking, she would have been immediately informed that it was a strong tablet. The information that drug checking harm reduction workers provide is not limited to whether a reagent test color change is consistent with MDMA. They provide a lot of useful info and harm reduction suggestions. So, Leibie’s point, as stated, is faulty.

On-Site Testing Is Helpful Even with New Psychoactive Substances

Leibie statement: “The greatest concern however, is that on-site tests cannot detect new designer drugs on the market, such as flakka, liquid acid or NBOMe compounds.”

Sample of LSD dropped on blotter tested with Ehrlich reagent turns purple.
NBOMe Results. NBOMes respond differently than LSD to field reagents

(Forget for a moment that the way the sentence is worded implies acid is a “new designer drug”…) This statement is misguided because of the inappropriate conflation of “on-site” with colorimetric field reagent tests. It’s also inaccurate because the NBOMe compounds do change color and can be ruled in or out even at very low doses. LSD (acid) is also detectable using field tests. The Ehrlich reagent turns purple in the presence of LSD. This sample of liquid LSD (far right) was dropped onto paper towel and the field tests did a fine job of showing the presence of LSD.

As we have written before, NBOMes do not fluoresce under UV lamps, while LSD does, and NBOMEs show a distinct set of field reagent reactions (above). I give Liebie another “clearly wrong”.

Advanced Scientific Analysis

Leibie statement: “Unfortunately, these dangerous compounds frequently are mixed with more familiar drugs, such as ecstasy, speed or ice, requiring highly advanced scientific analysis to be detected.”

This statement underscores the author’s lack of awareness that “advanced scientific analysis” is a practical option for on-site testing, if only it weren’t disallowed in most places. It also suggests a weak understanding of the field reagents he’s so strongly arguing against. Reagent field tests can rule in or rule out two of the three most “dangerous” drugs that he lists, the NBOMes and LSD (acid). For alpha-PVP (referred to as “flakka” here), he is right that it does not change color with the standard Marquis, Mecke, or Mandelin reagents. What a tremendous teaching opportunity for harm reduction workers to talk about adulterated drugs and the uncertainty of field tests (they can even point people to illustrative examples from EcstasyData, where we have reagent results side by side with the GC/MS lab findings). It seems Mr. Leibie is arguing against having those educational opportunities at large festivals.

And, while there are plenty of examples of NPS substituted for or adulterating more familiar drugs, the accuracy of the claim that this is a “frequent” occurrence is moot, since, just as the author points out that there are “no quality or consistency guarantees” for illicit drugs, there are also no representative sets of data about analyses of illicit drug samples available for public scrutiny (except maybe in the Netherlands). Law enforcement groups may analyze samples of seized drugs, but results are not typically shared with the public.

No Evidence that On-Site Testing Worsens Risks

Leibie statement: “Countries that have gone down the pill testing route do not provide any comfort that this approach works.”

Leibie makes several errors in the text he uses to support this statement. First, there is nothing like a valid apples-to-apples comparison between the different countries. Australia has a unique illegal drug market that is distinct from the UK’s. The Australian government runs one of the tightest customs operations in the world, in the confines of its own island continent, impacting Australia’s drug market much differently than the European-influenced UK. It is unclear why Leibie would feel qualified to offer a comparison of the effectiveness of unspecified relative amounts of harm reduction efforts in unspecified numbers of events with an unknown number of participants. It’s just weird. His statement qualifies as “most likely wrong”. The Netherlands are one of the only countries that has anything like a proper “pill testing route” with their DIMS project. And they don’t allow on-site lab gear at big events run by harm reduction workers.

False Sense of Security: A Real Problem

Leibie statement: “They also potentially leave consumers with a false sense of security that the party drugs they buy may be safe. It could be a deadly assumption.”

I think this is perhaps the most helpful statement in Leibie’s article. There is no question that many people misunderstand the risks of the drugs they are taking. Moreover, inexperienced use of field reagents can provide a false sense of security. People sometimes confuse lower risk with “safe”, or mistake harm reduction for harm elimination.

And it’s true that, sadly, sometimes people die after taking pharmaceuticals or recreational drugs in reasonable ways.

On-Site Testing Makes the World Better, Not Worse

Although the prominence of Leibie’s article offered a great opportunity to discuss the pros and cons of on-site testing, particularly the entirely relevant strengths and weaknesses of reagent testing, this opportunity was missed.

The author showed little knowledge of the specific area of music event or festival drug-checking. Performing tests at hot, dusty, remote events, with bass vibrations and the complexity of imaginative combinations of substances will always present challenges, but the experts running these services do tend to be well aware of these limitations.

The harm reduction projects that have been set up around the world are working within the parameters of government policies that seem at times to obstruct their efforts to serve the interest of public health. Despite all these conditions, and shoestring budgets, these groups are connecting people with specialist advice, mentors and peer support to ensure that on-site drug checking makes the world better, not worse.

Great Documentary: The Sunshine Makers [spoiler alert]

Fire and I just finished watching a preview copy of The Sunshine Makers, a documentary about 1960s LSD manufacturers. We were very impressed!

The quality of the content, editing, storytelling and sound, as well as inclusion of old photos, film footage and video are all amazing, but what makes it really stand out is the voice-reenacted law enforcement records and on-camera interviews with officers about the prosecutions of Nick Sand and Tim Scully.

Scully and Sand in Lab

The film tells the Sand/Scully stories with historical details we have never heard before, and includes audio and visual styling that add depth and entertainment value. For example, cutaway animations layered with stills of buildings, revealing miniature scenes of lab work happening inside them, are super clever.

Cosmo Feilding-Mellen and his filmmaker team include a few hilarious bits, like having Nick Sand dress up in a fishing outfit, while in voiceover he recounts a story of fleeing to Canada by pretending to be a fisherman. They do a fun job of narrating a car chase, interleaving storytellers that include a police investigator who was working to imprison Nick for LSD manufacturing.

What The Sunshine Makers helps clarify is that Nick was and is still an activist. While Tim Scully started out an activist, the downside of being a black market synthetic chemist and spending years in prison have him sounding a somewhat more constrained note.

Overall, this is one of the best made and most interesting looks inside the LSD distribution ring that Sand and Scully were a part of. Check out the trailer on YouTube and see the full version once it’s released, both in theaters and video-on-demand. :]

Technical Oddity: Dutch Testing Service (DIMS) Defines Pure MDMA Crystal as 84% Pure

Executive Summary: Different labs use different standards for reporting percentage purity assessments and also for mass when doing quantitative measurements for psychoactive drugs like MDMA. One lab’s 84% might be another lab’s 100%. This also means one lab’s 84 mg might be another lab’s 100 mg.

Long Version:

Erowid friend and Internet drug geek, Borax, pointed out a paper that analyzed some of the Dutch Trimbos Institute’s DIMS data. The peer-reviewed article was published in the journal Addiction: “Purity, adulteration and price of drugs bought online versus offline in the Netherlands” (2016). We love the Dutch DIMS testing service and have written about it before.

The publication of this article did not reveal a lot that we didn’t already know, but has brought into focus a heated argument that has been ongoing in public and private discussion forums about analytical methodologies for on-site and lab drug analysis.

What does it mean when a lab reports that a powder is 100% pure MDMA? What does it mean when a lab reports that a tablet contains 100 mg of MDMA?

The reason for writing about this is that there are no simple answers to those questions, though it seems like there should be.

Some online vendors of research chemicals have stated that various labs’ purity results in the 75-85% range mean that the sample was really “100% pure”, because of different ways of handling the mass of the sort-of-attached non-psychoactive salt anion. An anion is a negatively charged counter-ion that balances the positively charged, nitrogen-bearing drug molecule. When freebases are turned into salts, an anion is added.

The main case and the one that’s relatively easy to talk about is MDMA. MDMA is normally produced and distributed as MDMA hydrochloride (HCl), which is MDMA in a solution that has been converted to a crystalline form—-a “salt”-—by bubbling hydrochloric acid gas through the liquid. This causes the MDMA to turn insoluble in the solvent, precipitating out as MDMA HCl crystals. There are other possible salt forms of MDMA, but this is the “table salt” (most common salt form) of ecstasy/molly.

In fact, normal table salt or culinary salt is usually considered Sodium Chloride, or NaCl. We’re virtually swimming in tiny amounts of acids and salts in our normal environments. Remember your protective eyewear!

In addition to chloride salts like HCl, there are numerous anion salts possible, such as sulfide, fluoride, and bromide. For some psychoactive chemicals, the specific salt form can make a big difference in determining a dose. Mescaline has been distributed historically as Mescaline hydrochloride, Mescaline sulfate, Mescaline citrate, and Mescaline acetate. All of these have slightly different mass ratios between the base mescaline molecule and the portion that is the partially-bound anion. One could theoretically get 25% more or less mescaline, from a consistently weighed amount, depending on which salt form is involved.

This can be super complicated and technical and I doubt anyone is reading this who doesn’t get the basic premise. But there are technical issues like having some salt anions that bind two-to-one or one-to-two in crystalline forms. See What is the molecular weight of LSD tartrate? and many, many other discussions for crazy-making levels of detail.

As lab testing using GC/MS, HPLC, and FTIR has become more available and more projects are publishing their data and providing harm reduction information to individuals on the basis of their findings, it becomes increasingly important for more people to understand basic elements of some of the technical issues involved.

When this question of MDMA mass came up again this week, we asked the authors of the paper and the folks who work at Trimbos the following:

It has been suggested that DIMS might be using MDMA Freebase as the basis for mass and purity calculations, rather than salt masses, such as MDMA HCl. It is not described in any of your papers that I can find, but perhaps these questions will simplify the issue:

1) If DIMS received a powder sample of material that contained only MDMA HCl and nothing else, what would the reported purity be? 100%?

2) If DIMS received a tablet sample that contained 100 mg of MDMA HCl and 200 mg of lactose and inactive binders, what would the reported amount of MDMA be in that tablet? 100 mg? or would that qualify under your reporting rules as 84 mg of MDMA (freebase)?

And we got a very clear answer from the excellent Dr. Tibor Brunt:

“Indeed we use freebase as analysis standard. That actually means that if we report 100 mg MDMA in a pill, it is 119 mg in MDMA HCl. Our lab has always left out the salt component of psychoactive substances, since this component is not psychoactive. And if we’d receive a powder with 100% MDMA HCl this would be 84% maximum purity like you said.”

The reason they would define pure MDMA HCl crystal as only 84% pure is a little technical, but suffice to say it is not the only way to report an analytical result.

The reason that an expert group like Trimbos would decide to report masses this way is to normalize all their information across all salt forms of MDMA. I imagine, though I don’t know, it could be related to different types of quantitative methodologies that they have been working with for a long time.

So, dear drug geek reader, the question is not whether this issue is real, but, exactly what methodology and reporting measures are used by the analytical group you’re working with.

Update Jan 17, 2017: #

Energy Control of Spain, on the other hand, answered that they use MDMA HCl as their mass standard. They answered the questions clearly:

1) Our results directly provide the result of the salt of the substance, as
we’re using a salt as a reference standard. This means that the purity of a
sample with only MDMA HCl could be 100%.

2) Therefore, a tablet with 100mg of MDMA. HCl would be reported as 100mg
of MDMA.


Update Jan 18, 2017: Safer Party #

SaferParty and the cluster of groups in Switzerland that do work around that brand are very clear in all of their caution and warning publications that they are using MDMA HCl as their basis. For instance, “120 mg MDMA * HCl können zu viel sein”.

On Jan 30, 2017, they followed up with a long detailed answer to our questions.

Dear Earth,

Here the answer from our lab, i hope this clears things up:

As a reference standards-producing laboratory we’ve got most of our standards as solids in our hands, e.g. (water-free) salts. This is in contrast from what you get most times when buying solutions of reference standards from other companies (e.g. Cerilliant etc.). They usually sell the free base as a solution. Due to that, we are using mostly salts for calibrations. The second reason for that is, most of the time we are obtaining samples in salt forms for analysis (e.g. cocaine, heroine, MDMA, amphetamine, methamphetamine and other phenethylamines etc.); though we do not determine what kind of salt the sample consists of (e.g. hydrochloride, sulfate, acetate etc.).

We have had quite good experiences with this so far, as the sum of e.g. mixtures of amphetamine-coffeine-containing samples, when otherwise pure, reach 100% in sum when calculated with amphetamine hydrochloride. When exceeded 100% one may assume it contains a certain amount or all as free base. When the results are displayed as free base one can calculate any possible salt form. We think, according to the black market products here in Switzerland, it makes sense to give the results calculated for the hydrochloride salts, but for comparison with other labs/other countries the use of free base content would be the only value to make sense. Nevertheless, our results can easily be recalculated to the free base content, at least when knowing the type of compound we applied for calibrations/calculations.

We see it from the way that most dosage recommendations for a psychoactive compound to be taken orally or by snorting are given in the salt form (if possible), so this substantiates the indication as salt. With DMT as an example, we indicate the free base as content.

A short question the relatives the senses of indicating “purity” or “content”:

When having a chemically pure amphetamine sulfate (e.g. 100% Amphetamine sulfate”), its content of amphetamine free base is 73.4%. When having chemically pure amphetamine hydrochloride (e.g. 100% amphetamine hydrochloride), its content of amphetamine free base is 78.8%. When only seeing these numbers, which would you judge to be more pure? The lay would say it to be the second, but chemically both salt forms are chemically absolutely pure (100%).

A problem that comes in is, when having, e.g., a chemically impure amphetamine hydrochloride and reaching a displayed content of 73% amphetamine free base, one may imagine this to be a nearly chemically pure sulfate (close to the maximum content of 73.4%), but in fact it is a rather impure hydrochloride (73% out of a maximum content of 78.8%). As long as one does not determine the counterion (salt) this remains problematic.

When calibrating and calculating with salts, a measured sample consisting of free base would yield a result above 100%.

Each calibration/calculation has its own advantages, be it the use of free base, hydrochlorides, or hydrochlorides monohydrate, etc.

Let’s go to your questions:

“1) If SaferParty received a powder sample of material that contained only MDMA HCl and nothing else, what would the reported purity be? 100% ?”
As we used waterfree MDMA*HCl for calibration, we would report 100% content. As most of the samples measured here are on hand as the monohydrate (MDMA*HCl*H2O), the measured content mostly lies around a maximum of 93%.

“2) If SaferParty received a tablet sample that contained 100mg of MDMA HCl and 200mg of lactose and inactive binders, what would the reported amount of MDMA be in that tablet? 100mg ? or would that qualify under your reporting rules as 84mg of MDMA (freebase)?”
Our reported content would be 100mg MDMA*HCl.

Best regards,

Update Jan 19, 2017: The Loop #

The Loop offers analysis at music events in the UK to improve safety for partygoers and facilitate care by medical staff. When they report quantitative results for MDMA, they answered our questions as follows:

1. 100% purity
2. 100mg of MDMA (since the HCl salt is ubiquitous and service users
simply call MDMA.HCl “MDMA” we do not complicate the information they are
already getting with a description of why we are calling it something
different).

Update Jan 19, 2017: CheckIt! Austria #

CheckIt! Austria very generously took their question to their technical staff and verified their answer before getting back to us:

Our chief chemist just got back to regarding your question.

We use MDMA.HCl to prepare our standards for quantitative measurements. So if we would receive sample solely consisting of MDMA.HCl, the result would be 100%. Quantitative MDMA results in tablets are also reported as HCl. So if a tablet contains 100mg MDMA.HCl and let’s say 100 mg alpha-Lactose monohydrate we would report 100mg MDMA content.

Xiao Ren Ren : The “Little People” of Yunnan

This is a very fun paper.

Xiao Ren Ren : The “Little People” of Yunnan by David Arora in 2008. It’s about his visit to Yunnan, China where he encountered edible boletes (mushrooms with spore pores instead of gills) that stained blue and reportedly caused people to see “little people”.

Also on ResearchGate.

“And if I don’t stir-fry [the mushrooms] for ten minutes?”

“Ahhh,” the man said, his eyes bright and mischievous and his wide grin punctuated by a massive, gleaming metal molar. “Well, then of course ‘ni kan xiao ren ren’ (you will see the little people).”

I don’t understand why Arora wouldn’t have collected dry and wet samples of each, sent parts to a lab, and saved parts for later confirmation. Even tiny parts of biomaterial can have the DNA sequenced relatively cheaply these days.

But, regardless, there are many fungal mysteries still to be worked out in the world.
