Risk assessment

This sample, sold as 3-MMC (3-methylmethcathinone), did not contain 3-MMC, but methamphetamine and a small amount of 3-CMC, as well as various synthetic impurities.

In case of confusion or misdeclaration of these substances, the risk of overdose is extremely high, as methamphetamine is dosed much lower than 3-MMC. Also, the methamphetamine effect is very different from that of 3-MMC. Methamphetamine, especially in higher doses, has a strong stimulating and uplifting effect, whereas 3-MMC has a more euphoric effect. In addition, methamphetamine is effective many times longer than 3-MMC, which can lead to mental overload.

The chemical structure of 3-CMC is similar to that of 3-MMC and is often marketed on the internet as a mephedrone substitute. Compared to 3-MMC, 3-CMC is dosed slightly lower. Due to the lack of scientific studies on 3-CMC and the potentially neurotoxic effect of 3-CMC, we advise against its consumption.

There is no information available on the interaction of the substances.

With powders and crystalline samples, false declarations occur again and again; it is therefore essential to have these tested before consumption!

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.
