Risk assessment

One as 3-MMC declared as 3-MMC did not contain 3-MMC, but 3-CMC (3-chloromethcathinone, clophedrone) and iso-3-CMC.

3-CMC is a new psychoactive substance (NPS). There is hardly any information available on the risks, side effects and long-term consequences of 3-CMC. It is assumed that 3-CMC has a high neurotoxic effect. The chemical structure is similar to that of 3-MMC and 4-MMC (mephedrone) and is often marketed on the internet as a substitute for mephedrone. Compared to 3-MMC, 3-CMC is dosed slightly lower.

iso-3-CMC is an isomer of 3-CMC. No reliable information is available on the risks, side effects, long-term effects and toxicity of iso-3-CMC. The interaction potential with 3-CMC is completely unknown.

Due to the lack of scientific studies on 3-CMC and iso-3-CMC as well as the potentially neurotoxic effect of 3-CMC, we advise against consumption!

In addition, an unknown synthetic impurity was detected. This means an additional unknown health risk.

In the case of powders and crystals, misdeclarations occur time and again; it is therefore essential to have these substances analyzed in a drug check.

Alert level

Safer Use


Have your substances tested in a Drug Checking


If you do not have the possibility to have substances analysed, always test a small amount to avoid overdoses.

Wait and see

Wait 2 hours after oral intake, as there are always powders / crystals in circulation with unexpected active ingredients, which can have a later onset of action.


Always use your own sniffing utensils when applying powders nasally (sniffing) to avoid infecting yourself or others with diseases.
