3-MMC

3-MMC is a synthetic stimulant-entactogen of the substituted cathinone class. It is a structural isomer of mephedrone (4-MMC) and first appeared in Sweden in 2012 as a designer drug alternative following mephedrone's widespread prohibition. It quickly gained presence on the online research chemical market and has frequently been marketed as a mephedrone substitute. Insufflation of this substance is reported to be notably painful.
