Source-derived summary

Methedrone (para-methoxymethcathinone, 4-methoxymethcathinone, bk-PMMA, PMMC, methoxyphedrine, 4-MeOMC) is a recreational drug of the cathinone chemical class. Chemically, methedrone is closely related to para-methoxymethamphetamine (PMMA), methylone and mephedrone. Methedrone received media attention in 2009 after the death of two young Swedish men. In both cases toxicology analysis showed methedrone was the only drug present in both men during the time of their overdose and subsequent deaths.

Uses

Dosage

There is little information available about how Methedrone is dosed. According to users, a single dose of Methedrone varies from 50 to 500 mg with effects lasting 45 minutes to two hours. There are at least two cases known of fatal intoxications with Methedrone. In the first case, the postmortem femoral blood sample of the patient contained a concentration of 8.4 μg/g Methedrone, the patient died 16 hours after consumption (with polysubstance use detected). In the second body the concentration in the femoral blood sample was 9.6 μg/g, with Methedrone being the only toxic compound detected. The scientific investigation of these cases suggests that the Methedrone alone was responsible for these deaths and that the concentrations in the femoral blood represent the fatal levels of methedrone.

Editorial summary

“Methedrone” enters the record as chemical compound. Crown Archives preserves that source wording while asking what Methedrone, chemical and compound can confirm, complicate or overturn.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current lead gives the account dated anchors—2009—that can be checked directly. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Methedrone, chemical and compound.
Editorial analysis

Why this record matters

“Methedrone” is worth following because a concise public description often conceals a longer documentary argument. Here, Methedrone, chemical and compound provides the most credible route into that argument.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Feb 26, 2026. The linked authority identifier is Q2506962. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2009.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
