Summary TheDrug.Wiki TripSit PsychonautWiki

3-MMC is a structural isomer of mephedrone created as a legal replacement after 4-MMC prohibition. It acts as both a reuptake inhibitor and releasing agent for dopamine, norepinephrine, and serotonin, with stronger dopaminergic and noradrenergic activity than mephedrone. Insufflation causes significant nasal discomfort.
