What is mephedrone?
Mephedrone (Mieow, Meow, Meph, MCAT, 4MMC) is the synthetic (man-made) stimulant 4-Methylmethcathinone, chemically related to cathinone, the psychoactive chemical class present in the khat plant. The effects of mephedrone are often compared to those of MDMA, MBDB, bk-MDMA (methylone), cocaine, methamphetamine and other stimulants.
Because of its short duration and intense rush, there reports of compulsive re-dosing, resulting in the use of more mephedrone than intended. Although it is not a ‘plant food’, it is often sold as such on the internet. Some users report it to be contained in some legal highs. It is sold as a white powder, crystals, capsules and in pill form.
Classification
Mephedrone is classed as a stimulant; this term refers to the effect of the drug on the central nervous system and not to a user’s mood. Stimulants cause breathing and heartbeat to speed up and body temperature to rise.
How is mephedrone used?
Mephedrone can be taken:
- Orally: (powder wrapped in cigarette paper and “bombed” or ingested in capsule or pill form). Swallowing lasts longer than snorting but the effects take longer to appear. It is the most common method of administration.
- Nasally: (snorted with straw or banknote.) Snorting comes on quickly and effects are usually felt within 15 minutes and peak within half an hour. Effects fade after around an hour.

Effects from regular mephedrone use
Little is known about long term effects due to the short history of its use.
Mephedrone may increases heart rate and blood pressure, putting increased strain on the heart.
Some users have reported chest pains, palpitations, and irregular heart beats. There have been fatalities where mephedrone had been used prior to death.
Is mephedrone addictive?
Initial reports suggested that mephedrone was a "non-addictive" alternative to methamphetamine, cocaine, and other stimulants, but there is increasing evidence that it causes compulsive use patterns that are similar to or stronger than those of other recreational stimulants.
It is possibly physically addictive, although physical withdrawal symptoms are likely not to be life threatening. However, psychological addiction in some users seems to be a problem with this substance.
