Mephedrone is a fairly new recreational drug, and has greatly increased in popularity over the last years and is now the third most popular drug (Global Drugs Survey, 2011). Mephedrone is derived from the class of drugs known as the ‘cathinones’. It is a stimulant with psychoactive properties.

Mephedrone’s rising popularity, along with increasing media attention, has made it the most talked about drug over the last few months. Its recent prevalence could be associated with the decrease in purity and availability of other recreational drugs such as MDMA (ecstasy) and cocaine. Its effects have been noted as similar to both of these drugs, combining induced feelings of happiness with an ability to stay awake and dance or be sociable.
