Between 2009-2011 extreme stories about Mephadrone were hitting the headlines everywhere. Although Mephadrone has been associated with some deaths in the UK, in Australia the hype around Mephedrone hasn’t necessarily matched the reality.


Mephadrone (4-methylmethcathinone) is a stimulant-type drug. It is often described as a “new and emerging” or Novel Psychoactive Substance drug. It was originally sold as an alternative to drugs like speed, ecstasy and cocaine. It is often marketed as a plant fertilizer or a “research chemical”.

It got the nickname meow-meow because it is chemically similar to the cathinone found in the Khat plant. 


Meph, meow- meow, m-cat, plant food, drone, bubbles, kitty cat, Bath salts, 4-MMC.


Reliable data on rates of use are not yet available. After a peak in reported use in 2011 it seems users now prefer other stimulant-type drugs with less negative effects. Recent reports from AOD services of young people using “Bath salts” may point to continued use.
