Mephedrone (2-mmc/3-mmc/4-mmc)

What is it?
A synthetic stimulant that is often found in powder or crystalline form. 2-MMC and 3-MMC are chemical modifications of mephedrone (4-MMC/4-Methylmethcathinone). 2-MMC and 3-MMC are sometimes sold as mephedrone (4-MMC), although they differ in effect and dosages. 2-MMC and 3-MMC affect the dopamine level; users describe the effect as “cocaine-like” or “speed-like” effect where mephedrone (4-MMC) is a bit more “MDMA-like”. They are also referred to as mephy, meph, mephe, miaw, miw, meow or m-cat/mkat

Drug checking services in cities like Berlin and London are increasingly finding that substances sold as mephedrone (MMC) often contain other synthetic variants, particularly CMCs or NEP (N-Ethyl-Pentedrone). These substances are poorly researched, and their effects and risks are largely unknown.
