meow is a relatively new drug to hit the streets. It is basically methadrone (4-methylmethcathinone) aka 4mmCAT (the "CAT" part being the reason for the nickname meow) which is a psychoactive drug. Although Mephedrone is often compared with the entactogen stimulant MDMA/Ecstasy, Mephedrone has predominantly stimulant properties. This means that the effects of Mephedrone tend to be nearer to Amphetamine or Cocaine then to MDMA/Ecstasy.
Meow/Mephedrone is most commonly sold as a white powder or crystal form or capsules containing the powder. It can also be found in pill form. It is sold as plant food via internet, some users report it to be contained in some legal highs and sometimes sold mixed with Methylone, often known as “Bubbles”
