What is mephedrone?

Mephedrone is also called miaow, meow and MCAT. It's a man-made amphetamine stimulant. It comes in powder, crystal or pill form, and is very fast acting but with short-lasting effects. It's sometimes sold over the internet as ‘plant food’. It's not plant food.

What does mephedrone do to you?

The full effects of mephedrone on the body aren’t fully understood.

When you first take it, you’ll:

  • feel more energetic, or ‘rushy’
  • be alert and talkative, and have trouble sleeping
  • feel more connected to music and the people around you
  • lose short-term memory and find it hard to concentrate.

Physically, you might:

  • have raised heart rate, blood pressure and temperature
  • feel sweaty
  • have nosebleeds if you’ve snorted the drug
  • want to take more mephedrone.

Mephedrone is very addictive, meaning that once you’ve taken some, you’ll probably want to take more straight away. This is dangerous, because it increases the likelihood of overdosing.

The longer-term effects of taking mephedrone too often aren’t very well understood. Some known issues are:

  • heart problems (such as increased heart rate or an irregular heartbeat)
  • increased rates of depression
  • increased rates of psychosis and schizophrenia.
