Risk assessment

This sample, declared as mephedrone, does not contain 4-MMC, but 3-CMC, 3-MMC, 4-CMC, amphetamine, MDMA and caffeine.

3-MMC (cathinone substance group) is very closely related to mephedrone. The effects of the two substances are therefore also comparable. The effect of 3-MMC is mainly empathogenic (empathy-enhancing), entactogenic (intensifying emotions), stimulating, euphoric and aphrodisiac. 3-MMC is described by users as less euphoric and empathy-enhancing than mephedrone. This can lead to an unintentionally high dose of 3-MMC being consumed.

4-CMC belongs to the cathinone group and is structurally related to mephedrone (4-MMC). 4-CMC is described as having a strong performance-enhancing and euphoric effect. Some users report severe headaches as well as kidney and liver pain on the days following consumption. It is also reported that the substance can trigger a strong urge to re-dose, which increases the potential for addiction. 4-CMC and 3-CMC are suspected of being neurotoxic. There is hardly any information available on further risks, side effects and long-term consequences of both substances.

The interaction potential between the psychoactive substances contained in this mixture is completely unknown. Due to the possible neurotoxic effect and increased stress on the body, we advise against consumption!

With powders and crystals, false declarations occur time and again; it is therefore essential to have these substances tested!

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.
