What is mephedrone and what does it do?

Mephedrone is also called Miaow, Meow and MCAT. It's a stimulant made by humans. It's short-acting, and sometimes sold over the internet as “plant-food”. It's not plant-food. It comes as a powder, crystals or pills.

Drugs will always affect people differently. After taking mephedrone , someone might:

  • Feel more energetic or “rushy”
  • Feel alert and talkative, and have trouble sleeping
  • Feel more connected to music and the people around them
  • Lose their short-term memory and find it hard to concentrate
  • Have increased heart rate and blood pressure, and temperateure
  • Sweat more
  • Have nosebleeds if they've snorted
  • Feel like taking more mephedrone
These effects last no more than about an hour. People who take mephedrone will often want to take it again straight away. Mephedrone has a comedown afterwards like other stimulants.

We don't know heaps about the long-term effects of mephedrone because people haven't been using it for that long. It definitely puts strain on your heart in the short and long term, and people have said it gives them chest pains and messes with their heartbeat. Some people have died after using mephedrone.


These are some other issues people who use mephedrone could run into.
  • They feel like taking more as soon as it starts to wear off. Taking more increases the dangers and damage, and can lead to overdose. If you overdose, or someone around you does, call an ambulance
  • It can affect mental health problems like depression, anxiety and schizophrenia, even if you don't know you're vulnerable to them
  • It impairs your ability to drive
  • You can get hooked and feel like you have to have more
  • It's illegal, and getting caught could mess up your travel, study or life plans
  • If you mix it with other drugs, alcohol or prescription medication it puts extra strain on your body and could be more damaging.
