Methedrone (para-methoxymethcathinone, 4-methoxymethcathinone, bk-PMMA, PMMC, methoxyphedrine) is a recreational drug of the cathinone chemical class.[2] Chemically, methedrone is closely related to para-methoxymethamphetamine (PMMA), methylone and mephedrone.

Health risks[edit]

The health risks associated with methedrone are mostly unknown, but are expected to be similar to other cathinones.[3] Methedrone was almost immediately withdrawn from sale by initial vendors after reports of adverse health effects.[citation needed] Some amphetamine analogs containing a para-methoxy group are known to cause severe hyperthermia and even death due to concurrent MAOI and monoamine releasing action.[4]


The deaths of two young men in southeast Sweden in 2009 were attributed to methedrone overdose.[5][6] Both were comatose when found. One suffered cardiorespiratory arrest on the way to the hospital, while the second survived for 16 hours in the emergency department.


Its sale has been banned in Sweden.[citation needed]
