Risk assessment

This sample, declared as 3-CMC, contains the new psychoactive substances 2-MMC and 3-MMC instead of 3-CMC.

2-MMC (2-methylmethcathinone) is a rather new NPS (New Psychoactive Substance) and a cathinone of the amphetamine group. No reliable information is available on its risks, toxicity, side effects and long-term consequences. 2-MMC is often marketed on the Internet as mephedrone (4-MMC) or a 3-MMC substitute. According to user reports, the effect of 2-MMC is more comparable to 2-FA or amphetamine (performance-enhancing and stimulating), which is why many users have experienced a slightly different effect than expected. Thus, in the event of a false declaration, as in this case, there is an increased risk that a high dose of 2-MMC will be consumed unintentionally.

3-MMC belongs to the cathinone group of substances and is very closely related to mephedrone. The effect of 3-MMC is mainly empathogenic (increasing empathy), entactogenic (intensifying emotions), stimulating, euphoric and aphrodisiac.

Little information is available on the risks, side effects and long-term consequences of 2-MMC and 3-MMC. Consumption is not recommended!

With powders and crystals, false declarations occur time and again; therefore, be sure 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.
