Weekly Drug Purity Report

[ions]

It's the purple stuff that turns Marquis purple. because the purple is from food coloring. and the test says if it appears purple, it should not, and is not MDMA. It should go black.

The scary part about PMMA is passes reagent testing with flying colors. It also looks and tastes just like MDMA crystal. I was thoroughly bamboozled and I practice HR.

To echo Placebonaut, did it taste significantly different from MDMA (which to me often has caraway seed notes).


Disclaimer: tasting drugs to identify them isn’t the best HR; but information is information.

hmm, I thought for most tests pure PMMA will give a different result to MDMA?

During my thoroughly documented test, the reagent turned black as ink instantly. However. There were some irregularities my giddy ass didn't recognize at first; namely the color purple was also present witht the black. There also seemed to be an exothetmic reaction. I am aware reaction some reason is suspected in a small degree but this seeemed unusual. I swear it sparked a spiked a few times.


This stuff also looked funky. Huge crystals. That were in the reminiscent shape but also had a different fractal pattern and oileness.

Neither of these red flags are for me to dose some. The faft that it basic looks tastes z and smells just like MDMA. I need something was off 90min after dosing... so my dumbass took more. 24-48hr later I was sicker than I had even been. My insides hurt. I had a headache for A. WEEK STRAIGHT until I finally went to the hospital.

I got my first kidney stone 3 weeks later.

Caraway seeez?

Mdma has a chemical nauseating taste that makes me gag just thinking about it. But I heavily abused it. Seriously makes me gag thinking of the taste.

Like not 100% but that is what comes to mind pretty reliably to me. Like if you took a spoonful of them and chewed them up they have a type of bitterness that reminds me of that (more than the flavor of chewing sassafras roots does).

Talking about smell and taste is tricky, especially for chemicals as there are fewer reference points that are commonly experienced by most people.

thanks for the info, useful insight.

I'm not a reagent expert at all, so asking more to learn than anything, were you doing a Marquis test specifically? think that goes purple>black for MDMA but it's clear for PMMA so a mix would mask the PMMA i.e. you had a blend

The PMMA nugs sold to me had apparently been recrystallized with purple good coloring adding.

The crystals were large and resembled sone meth but less mdma.

But the overall raste and texture was nearly identical to meth, it mot more bitter and causitic tactic.

Drug Purity Report #38/26

Welcome to “last week on drugs”, the series by PRO Test that brings you fresh drug purity news from the clandestine market. In this week’s edition: developments regarding 3-MMC replacement, problem with underdosed pills and extremely dosed tablets.

Data fatigue is real, so here we come to give you the gist of what’s going on out there. For more details, photos, and other information on thousands of drugs, head out straight to the DrugsPRO app.

Expected: 3-MMC. Detected: NEP (95%). Location: Berlin, Germany. Date: 2026-09-15. Source: drugchecking.berlin.

3-MMC, the replacement of 4-MMC (Mephedrone), is getting harder to find in Europe.

In the past months we have recorded compounds such as most notably 4-BEC, 4-BMC, 4-CMC, 2-MMC and NEP sold as 3-MMC or 4-MMC. Researchers warn that the novel cathinones could be escaping their simplified expected pharmacological profile, therefore extra caution is advised. Lately to the creative adulterant mixtures there is a new addition: MDMA used as a cut for MMC.

Pills remain as unreliable as always.

A brief change from PMMA we report weekly as of late (the danger is not over, it just had not been detected this week), this time we focus on the dosages found in pills. Some are completely bunk, like a pink Trump from Madrid (Spain) found to contain only caffeine. Then other can contain several strong doses of MDMA (120mg+), like the blue Farru pill from Barcelona detected with over 250 mg of MDMA. With median pill around 160 mg (already around x1.5 of a common dose), both significantly underdosed and overly potent tablets pose an increased risk of accidental overdose.

Scam of the Week

Samples that were not what they were sold as. Substitutions like these can be picked up with a test kit before anything is taken.

• 4-MMC — Ketamine — 1 sample.
• Cocaine — Metamizole — 1 sample.
• Ketamine — Pregabalin — 1 sample.

Additional dishonourable mention: 2C-B pill sold in Bern (Switzerland) with only 1 mg of 2C-B.

Last Week at a Glance

• 43 samples from 4 countries (Austria, Germany, Spain and Switzerland) were included this week.
• 35 samples contained a quantified result, including 23 pills and 0 LSD samples.
• 12 samples contained more than one detected ingredient.
• No supported purity or content change was available for comparison.

More details, tables and sources are available in the full Drug Purity Report for Week 38, 2026, and of course in the DrugsPRO app.

Drug-checking results describe tested samples only and are not representative of the entire market.

Thank you for reading and catch you next week!

I got some stuff that was sold as 3-mmc. It was clean small crystals, I had to way to confirm it but it was very good, better than some of the post ban 4-mmc I’ve had. It smelled faintly of some of 4-mmc but I wasn’t that pissy smell. They are going to have similar smells with it been a 4-mmc isomer.
Id buy it again tbh

 

[nato23]

I don’t get how a lot of 4-MMC detected and 2-MMC but 3-MMC seems illusive? They are all isomers of each other.

I need to do some research.

Here’s what marquis does to a sample I was satisfied with.

 

[DrugsPRO App]

Kind reminder that neither anise smell nor purple/brown tint to Marquis reagent can be deemed sufficient to recognise PMMA, especially mixed with MDMA (https://protestkit.eu/how-to-detect-pma-pmma-pmea/). Only lab analysis or at least a TLC MDMA purity kit paired with colorimetric reagent tests can help provide a sufficient proof. Of course, having said that, even an anecdotal argument against using a product is good - can't ever be too safe.

Drug Purity Report #43/26

Welcome to “last week on drugs”, the news series by PRO Test that brings you fresh drug purity updates from the clandestine market. In this week’s edition: PMMA risk continues, NEP remains the leading missold cathinone and novel depressants found in supposed XANAX.

Available lab results originate mostly in Western Europe, but the detected patterns are likely to have a much wider reach.

Data fatigue is real, so here we come to give you the gist of what’s going on out there. For more details, photos, and other information on thousands of drugs, head out straight to the DrugsPRO app.

Medetomidine, a veterinary anesthetic medication with potent sedative effects has been found in a black market Xanax knock-off. This class of compounds is being as of recent years increasingly found in so-called “downers”, mostly benzodiazepines and opioids. Interestingly, in pills it was found pure, which means a simple quick test for presence of a benzodiazepine would rule it out. Unlike benzos, medetomidine can cause lethal respiratory depression.

PMMA continues to be missold as MDMA under various pill designs. So far confirmed this year in at least Trump, Gorilla, Red Bull, Club 555, Mitsubishi and Scorpion pills, but warning is not limited to those. While somewhat similar in structure to MDMA, the PMMA, perhaps a product of botched synthesis, poses a great risk of serotonin syndrome, and much weaker recreational effects, posing a high risk of accidental overdose. PMMA is a weaker, but still dangerous, analog of PMA, the most deadly MDMA adulterant. Warning: PMMA is being sold mixed with MDMA, requiring a lab analysis or TLC MDMA Purity Test Kit to detect it, not only reagent tests.

NEP (N-Ethylpentedrone) remains one of the main adulterants missold as 3-MMC and 4-MMC (Mephedrone), the most commonly sought out cathinones. Unlike MMC or even CMC, NEP does not offer same serotonine release effect, but a much stronger stimulation instead, likening the experience more to meth than MDMA, if seeking comparison to more old school drugs. NEP is also much more potent per dose, and is being found both pure and mixed in with other cathinones, making detection harder, although not impossible.

Scam of the Week

Samples that were not what they were sold as. Substitutions like these can be picked up with a test kit before anything is taken.

• Benzodiazepin → Medetomidine — 1 sample
• MDMA → PMMA — 1 sample
• 3-MMC → NEP — 2 samples

Last Week at a Glance

• 57 samples from 6 countries (Austria, Belgium, Germany, Slovenia, Spain and Switzerland) were included this week.
• 49 samples contained a quantified result, including 31 pills and 2 LSD samples.
• 17 samples contained more than one detected ingredient.
• MDMA was typically 166mg this week, against 156mg across the twelve months before.
