Mexedrone (3-methoxy-2-(methylamino)-1-(p-tolyl)propan-1-one also known as 4-MMC-MeO) is a putative stimulant and possible euphoriant of the cathinone chemical class with a potency of roughly 1/10th of that of mephedrone.
This compound has little to no history of human usage prior to its release in August 2015 as a newly available grey area research chemical. It has been primarily marketed as a legal alternative to mephedrone although anecdotal reports seem to universally suggest that it is largely inferior in its recreational effects due to its weaker potency, lack of stimulation and euphoria. It may have been developed as a result of another much more effective, but problematic mephedrone derivative, N-methoxymephedrone.
Mexedrone, or 3-methoxy-2-(methylamino)-1-(p-tolyl)propan-1-one, is a synthetic molecule of the cathinone family. Cathinones are structurally similar to amphetamines. They contain a phenethylamine core featuring a phenyl ring bound to an amino (NH2) group through an ethyl chain with an additional methyl substitution at Rα. Amphetamines and cathinones are alpha-methylated phenethylamines. Cathinones contain an additional ketone group bonded at R1.
Mexedrone contains additional methyl substitutions at RN (similar to MDMA and methamphetamine) and R4 of its phenyl ring. Mexedrone is named for the methoxy group (C3O-) bound to the methyl group located at Rα. Mexedrone is closely analogous to mephedrone, however, mephedrone lacks the additional methoxy group bonded to the α-methyl group.
Toxicity and harm potential
The toxicity and long-term health effects of recreational mexedrone use do not seem to have been studied in any scientific context and the exact toxic dosage is unknown. This is because mexedrone has very little history of human usage.
Anecdotal reports from those who have tried mexedrone within the community suggest that there do not seem to be any negative health effects attributed to simply trying this drug at low to moderate doses by itself and using it sparingly (but nothing can be completely guaranteed).
It is strongly recommended that one use harm reduction practices when using this drug.
Tolerance and addiction potential
As with other stimulants, the chronic use of mexedrone can be considered moderately addictive with a high potential for abuse and is capable of causing psychological dependence among certain users. When addiction has developed, cravings and withdrawal effects may occur if a person suddenly stops their usage.
Tolerance to many of the effects of mexedrone develops with prolonged and repeated use. This results in users having to administer increasingly large doses to achieve the same effects. After that, it takes about 3 – 7 days for the tolerance to be reduced to half and 1 – 2 weeks to be back at baseline (in the absence of further consumption). Mexedrone presents cross-tolerance with all dopaminergic stimulants, meaning that after the consumption of mexedrone all stimulants will have a reduced effect.
