Mephedrone is a stimulant drug that users say has similar effects to ecstasy, cocaine or amphetamine. It is most commonly sold in bags or wraps as a white powder. It is also sold over the internet and some specialist shops as tablets or capsules containing the powder. The powder can be snorted or wrapped in a cigarette paper and swallowed (bombed). The capsules or tablets can be swallowed.

When swallowed the effects come on fairly quickly, after half an hour or so, with the main effects lasting up to two hours, and tailing off after four hours. Users report a definite feeling of ‘coming up’ or ‘rushes’, as the drug takes effect. The main effects include feeling alert, a sense of calm wellbeing, excitement, stimulation, elevated mood and chatty.


When snorted, Mephedrone can damage the skin exposed to the substance in the nose and nasal passages, leading to inflammation, pain and nosebleeds. Common side-effects include dry mouth, suppressed appetite, poor concentration and short-term memory, increased heart rate, increased body temperature, palpitations of the heart, anxiety, depression, sweating, and pupil dilation. Users report the comedown as feeling miserable, tired and drained, wanting to take more and difficulty getting to sleep. These feelings can last well into the next day.
There have been several deaths reported in the media, where Mephedrone has been implicated. So far, the actual cause of death has yet to be determined.


It is possible that Mephedrone could be psychologically addictive. Many users report a strong desire to continue taking it. It is too early to say whether it is addictive or not.
