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.

Key Purity Differences

• Amphetamine median purity/content is 88%, compared with 38% in the yearly reference period.
• Mephedrone median purity/content is 54%, compared with 88% in the yearly reference period.
• MDMA median purity/content is 160mg, compared with 160mg in the yearly reference period.

Purity and Content

Median quantified results for 27 July–2 August 2026. The yearly reference is shown in parentheses where sufficient comparison data is available.

How to read this: Bold = this week’s median (typical) result; “Middle 50%” = half of the results; (*) = median from the last 365 days; ▲/▼ = higher/lower than last week.

Most Common Adulterants and Other Impurities

Across the last 365 days, 1,627 mixed samples contained 129 distinct additional ingredients.

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”.

Last Week at a Glance

• 68 samples from 4 countries (Austria, France, Slovenia and Spain) were included this week.
• 58 samples contained a quantified result, including 32 pills and 3 LSD samples.
• 20 samples contained more than one detected ingredient.
• Cocaine median purity/content is 38%, compared with 86% in the yearly reference period.

Key Purity Changes

• Cocaine median purity/content is 38%, compared with 86% in the yearly reference period.
• Mephedrone median purity/content is 49%, compared with 88% in the yearly reference period.
• LSD median purity/content is 88µg, compared with 65µg in the yearly reference period.
