Drug Purity Report #34/26. In this week’s report on drug market purity we are shining spotlight on fake hash, extreme MDMA pills and more PMMA.

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.

1. A fake hash sample found in Zurich contained 2 different synthetic cannabinoids: MDMB-4en-PINACA and ADB-4en-PINACA. We remind all cannabis users that with the current availability of CBD, the financial incentive is much higher to sell synthetic cannabinoids than real classic THC products.
2. Pills closing in on almost 300 mg of MDMA detected in Spain’s Tarragona and in Basel, Switzerland. The first is a grey Grim Reaper with “350mg” stamped (280 mg MDMA detected), and the other an orange Master Roshi (260 mg MDMA)
3. Although PMMA was not detected this particular week, due to more samples detected in the recent days we are repeating the warning. PMMA has been found in multiple samples this year. It has hardly any expected effects of MDMA, while having plenty of the undesired effects. Using a test kit is essential to reduce the risk of PMMA poisoning.

Drug Purity Report #33/26. Welcome to “last week on drugs”, a new blog post series by PRO Test dedicated to reporting on drug market purity. Since last week we have seen doppleganger Ecstasy pills, pills with more than 1 stimulant, and a continued diversity among cathinone samples. 

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.

• Doppleganger Ecstasy pills
  • Every pill should always be considered as different, as illustrated by most recent red TikTok and blue Punisher pills found in Austria. With half of the samples containing MDMA, and the other half caffeine, the risk of possible overdose increases exponentially. A weak effect (caffeine pill) can encourage person using it to ingest more and overestimate their tolerance.
• Multi-stimulant pills
  
  • Pills with both MDMA and caffeine were found in Austria, yet another kind of blue Punisher pressies. MDMA with amphetamine was found in a round orange pill in Innsbruck, and a Donkey Kong pill with NEP mixed with unknown compound was found in Slovenia, after recent detections in other countries throughout the region. 
• Cathinone diversity
  • As reported in the previous weeks, 4-MMC is increasingly rare and replacements are still all over the place. Those include from 3-CMC, 4-CMC, 2-MMC, 3-MMC, 4-BMC, and NEP, also reported by the Austrian lab as ethylpentedron, found this week.

Last Week at a Glance

• 217 samples from 6 countries (Austria, France, Germany, Slovenia, Spain and Switzerland) were included this week.
• 172 samples contained a quantified result, including 73 pills and 6 LSD samples.
• 89 samples contained more than one detected ingredient.
• LSD median purity/content is 172µg, compared with 69µg in the yearly reference period.

Key Purity Differences

• LSD median purity/content is 172µg, compared with 69µg in the yearly reference period.
• Amphetamine median purity/content is 10%, compared with 38% in the yearly reference period.
• Cocaine median purity/content is 65%, compared with 86% in the yearly reference period.

Purity and Content

Median quantified results for 10–16 August 2026. The yearly reference is shown in parentheses where sufficient comparison data is available.

Samples	Substance	Typical purity / content
58	MDMA	154mg (160mg*) Middle 50%: 131.5–191.3mg ▼
30	Cocaine	65% (86%*) Middle 50%: 31–75.5% ▼
10	Mephedrone	69.5% (88%*) Middle 50%: 48–88% ▼

Drug Purity Report #32/26. Welcome to “last week on drugs”, a new blog post series by PRO Test dedicated to reporting on drug market purity. This time – another week, another PMMA pill. On top of that more novel semi-synthetic cannabinoids and other research chemicals. 

Caution: warnings are not limited to compounds mentioned in this post. All our published lab results are warnings. No substance is 100% safe.

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.

• Donkey Kong PMMA pill in Zurich, Switzerland

Whoever has been putting out pressies (pills) with PMMA is not taking it easy. Another pill found with PMMA, and another sighting of one previously spotted. Considering the scale of European drug market and the evident cross continental spread, it’s reasonable to assume that at least several thousands PMMA pills are currently in circulation.

• Delta-8-THO in Maribor, Slovenia

The Slovenian drug checking NGO Drogart reported new semi-synthetic cannabinoids, THC butanenitrile oximes (THO). More details from Drogart:

The results of the analysis conducted at the National Laboratory for Health, Environment and Food showed that a sample of cannabis purchased as cannabis with the semi-synthetic cannabinoid tetra-9-hydrocannabinol (T9HC) in a physical store in Maribor contained two other semi-synthetic cannabinoids, delta-9-THC butanenitrile oxime (delta-9-THO) and delta-8-THC butanenitrile oxime (delta-8-THO).

Not much information is available about the substances delta-8-THO and delta-9-THOV. Users of the aforementioned semi-synthetic cannabinoids have reported intense effects, dissociation, blurred vision, nausea and loss of appetite in the past. There is currently no additional information in the literature about the effects of delta-9-THO.

Synthetic and some semi-synthetic cannabinoids are extremely potent and unpredictable substances that can cause rapid loss of consciousness, slowed or labored breathing, epileptic seizures, convulsions, frequent vomiting, agitation, delirium, psychotic episodes, aggressive behavior, chest pain, irregular heartbeat, confusion, fainting, irritability, hallucinations, paranoia, and in the most severe cases, sudden death.

• Fake Xanax in Bern, Switzerland

A fake Xanax sample resembling the classic alprazolam pill checked by Swiss experts was found to contain Flualprazolam and Meclonazepam. With those compounds being so called “research chemicals” their risk profile is unclear, however flualprazolam is known to have longer lasting effects than alprazolam. Combined with possibly unfamiliar effects the overdose risk is high. In case of benzodiazepines overdose means memory loss, likely injury or other accident, significantly increased likelihood to follow bad ideas.

Last Week at a Glance

• 83 samples from 5 countries (Austria, France, Germany, Slovenia and Switzerland) were included this week.
• 76 samples contained a quantified result, including 39 pills and 7 LSD samples.

Drug Purity Report #31/26. We are back with another summary of the “last week on drugs”, the blog post series by PRO Test dedicated to reporting on drug market purity. This week we got more PMMA, cathinones and synthetic cannabinoids. 

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.

• PMMA is still around
  • The danger of finding PMMA in an Ecstasy pill remains relatively high. After multiple samples confirmed earlier this year now also a red-purple Red Bull pill containing 59 mg of PMMA was found in Vienna. PMMA is a hardly enjoyable substance, responsible for multiple deaths, but is also fortunately easy to spot using an MDMA test kit.
• Synthetic cathinones
  • The seek for 4-MMC replacement and obvious issues with availability are prevalent throughout Europe. People who tested samples assumed to be Mephedrone last week found 4-CMC and NEP. The latter, NEP, being much stronger (and not characterised as serotonergic), with particularly high overdose potential. Interestingly NEP was found pressed in same looking pill as the red-purple PMMA Red Bull.
• Synthetic cannabinoids
  • 1 sample from Austria was found with not 1, but 4 different synthetic cannabinoids. Although testing cannabis products is less common than e.g. powders, anecdotally the market has been increasingly saturated with synthetic cannabinoids at an astonishing rate. This can be attributed nowadays mostly to the availability of cheap and legal CBD and the unfortunate ignorance of most consumers, making deception easy. The risk for cannabis users is high. With fully synthetic cannabinoids (e.g. MDMB-INACA) posing an actual threat to life and kidneys, and semi synthetics (e.g. HHC-O) being at least unpredictable, testing cannabis products before use is a must – and costs pennies.

 

Last Week at a Glance

• 60 samples from 6 countries (Austria, France, Germany, Slovenia, Spain and Switzerland) were included this week.
• 52 samples contained a quantified result, including 25 pills and 1 LSD sample.
• 16 samples contained more than one detected ingredient.
• Amphetamine median purity/content is 88%, compared with 38% in the yearly reference period.

Drug Purity Report #29/26. Welcome to the first “last week on drugs”, a new blog post series by PRO Test dedicated to reporting on drug market purity. After creating the DrugsPRO app, we have realised that browsing all of the available data can be challenging. Therefore in this series of articles we will post updates, summaries and comments on the current state of drug quality, particularly in Europe.

Expert Comment

 

• Cocaine
  • Samples tested in Vienna proved to be of low quality, and more classic purity than the 80%+ medians which recently dominate cocaine lab reports. Detected impurities were Caffeine, Levamisole, Phenacetin and Procaine, and median purity was just 38%. Definitely a familiar issue among people who use cocaine.
• Mephedrone
  • The 4-MMC situation continues to deteriorate, with increasing prevalence of less seeked out cathinones sold as mephedrone, such as 2-MMC, 3-CMC, 4-CMC, 4-BEC, NEP, both pure and mixed. Having said that, 4-MMC remains available, and interestingly is being pressed into pills more frequently. This might signal a broader shift towards marketing cathinones more aggressively to the general population.
• Pink craze
  • Roughly half of the pills tested were pink. Pink pills and powders remain to appear popular. This week’s featured image portrays the 4-CMC pill “Lisa Simpson”. It is often accompanied by 4-CMC pills “Bart Simpson”.
