Mephedrone, also known as 4-methyl methcathinone (4-MMC) or 4-methyl-ephedrine is a synthetic stimulant drug of the amphetamine and cathinone classes. It is chemically similar to the cathinone compounds found in the khat plant of eastern Africa. It comes in the form of tablets or a crystalline powder which users can swallow, snort or inject, producing similar effects to cocaine.
Mephedrone was first synthesised in 1929, but did not become widely known until it was rediscovered in 2003 at which point it was legal to produce and possess in many countries. By the year 2010 it was made illegal in many European countries and became difficult to source as supplies depleted due to its popularity.
Since the discovery of online venders, Mephedrone is making a comeback with suppliers found on the dark and the worldwide web
Users have reported that mephedrone causes euphoria, stimulation, an enhanced appreciation for music, an elevated mood, decreased hostility, improved mental function and mild sexual stimulation; these effects are similar to the effects of cocaine, amphetamines and MDMA, and last different amounts of time depending on the way the drug is taken. Of 70 Dutch users of mephedrone, 58 described it as an overall pleasant experience and 12 described it as an unpleasant experience. In a survey of UK users who had previously taken cocaine, most users found it produced a better-quality and longer-lasting high and was less addictive. The users were also asked to compare the “risk”, and they answered that it was equal. A study of users in Northern Ireland found they did not equate the fact that mephedrone was legal with it being safe to use. This was contrary to another study in New Zealand, where users of benzylpiperazine thought that because it was legal, it was safe
