3-Methylmethcathinone also known as 3-MMC is a designer drug from the substituted cathinone family with stimulant effects. 3-MMC is closely related in structure to the popular illicit drug mephedrone (4-MMC) and is illegal in most countries that have banned mephedrone as it is a structural isomer of mephedrone. However 3-MMC has still appeared on the legal high market as an alternative to mephedrone and was first identified being sold in Sweden in 2012.
