Is Mephedrone (4-MMC) legal in Sweden?

Also known as: meow meow

Confirmed against a primary sourceVerified September 21, 2026
Legal status
Controlled. Mefedron is named in Förteckning I of the Swedish narkotikaförteckningar, which are Läkemedelsverkets föreskrifter (LVFS 2011:10) om förteckningar över narkotika, made under 3 § förordningen (1992:1554) om kontroll av narkotika. The version read for this cell is the consolidated text, which states on its own first page that it contains amendments through HSLF-FS 2026:26. The row reads «Mefedron 4-metylmetkatinon», and its international column reads P II, which is Schedule II of the 1971 Convention on Psychotropic Substances. Förteckning I is the tier for substances, plant material and fungi that normally have no medical use. 2-MMC and 3-MMC are separate rows and neither is this one. Klefedron, the 4-chloro analogue, is a third.
Consequences if caught
Capital exposure: none. Sweden has no death penalty for any offence, so no drug offence here carries capital exposure. The live cell recorded fines and up to 3 years' imprisonment for ordinary narkotikabrott and up to 10 years for grovt narkotikabrott, and that unlawful possession, use, transfer, supply and manufacture are all criminal.
If prescribed or medical
No mephedrone containing medicinal product is approved in Sweden and a Förteckning I substance has no accepted medical use and cannot lawfully be prescribed.
Documentation
There is no lawful personal import route. The live cell recorded the original narcotics classification on 25 May 2009 and named Förordning (1992:1554) om kontroll av narkotika as the control framework. That date is carried forward and was not re-derived.

  • Quotations in guillemets are the row's printed tokens in column order. Line wraps inside a name are rejoined, and a hyphen that exists only because of the wrap is dropped. Any further name printed in the row is reported in prose rather than inside the quotation, because the two column layout interleaves it into the middle of the chemical name
