Drug Purity Update Week 30, 2026

DrugsPRO sample 20260721SWZrT

Drug Purity Update #30/26. Welcome to “last week on drugs”, a new blog post series by PRO Test dedicated to reporting on drug market purity. In this week’s edition: the return of PMMA, more old-school Ecstasy and the question “what is going to replace Mephedrone?”.

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 BACK! 

    • The infamous PMMA, which killed multiple people in the early 2010s, is unfortunately back. Despite of abundance of MDMA on the market (the main risk being taking too high of a dose, accidentally), at least 4 different pills were detected already this year in the Netherlands, Switzerland, Spain and Poland (the last two reported by Nectar Spectra Labs). The PMMA pills are:

      1. Trump (pink-grey)
      2. Mitsubishi (yellow/beige)
      3. Tesla (pink)
      4. Red Bull

      Most of those are available in the DrugsPRO app, some have been passed on to us directly by Nectar experts.

 

  • MDMA with Amphetamine
    • Do you know how many people suggest Ecstasy pils contain MDMA mixed with Amphetamine? Well, that is a myth… most of the time. The misconception comes from the fact how differently “Molly” can affect users,  both due to personal predispositions, as well as the common unintuitive decrease of energy on high doses of MDMA. But, to every rule there is an exception. Last week the Swiss drug checking specialists detected 30mg of Amphetamine mixed with 155 mg of MDMA in a yellow Bitcoin pill. A hefty dose of both, significantly more than expected for a single person. Interestingly, bitcoin pills appear to have a significant variance in contents, unlike most other logos.

 

  • What is going to replace mephedrone?
    • Ever since Mephedrone (4-MMC) start to get banned, the chase to find a replacement begun. And yet, due to lax regulations in particularly the Netherlands, situation quickly stabilised, and 3-MMC became the drug of choice for many European party goers. Recently, however, 3-MMC was banned there too, and it seems like 2-MMC is not picking up as replacement. Currently dealers are trying to sell 2-MMC, 3-CMC, 4-BEC, 4-BMC, 4-CMC and NEP as Mephedrone. Situation remains dynamic, with most of those compounds sharing a similar piece of the market. Due to low sample size, currently more information on that trend is not available.
