    Summary TheDrug.Wiki

    3,4-DMMC was first detected in Europe in 2010 and marketed under street names "Ocean" and "M2" as a mephedrone replacement. Potency is noticeably lower than mephedrone; users describe effects as "blunted" or "foggy." Nasal administration produces pronounced chemical burn and rhinorrhea. Pharmacodynamic data show similar affinity at norepinephrine and serotonin transporters but weaker dopamine transporter activity compared to mephedrone, resulting in mild empathogenic effects and potentially higher cardiovascular strain.
