Mephedrone (4-methylmethcathinone) is a stimulant which is closely chemically related to amphetamines. Users report that mephedrone produces a similar experience to drugs like amphetamines, ecstasy or cocaine. Mephedrone is a white, off-white or yellowish powder which is usually snorted, but can also be swallowed in bombs (wraps of paper) and may also appear in pill or capsule form.
Mephedrone is probably the most well known of a group of drugs derived from cathinone (the same chemical found in the plant called khat) although two other compounds are also increasingly recognised on the market. These are methedrone and methylone. The effects of methedrone are said to be broadly similar to mephedrone, although methylone is said to give the user an experience more closely related to taking ecstasy (1).
Other less common compounds from the cathinone family that may be used recreationally include flephedrone (4-FMC), bromomethcathinone ( 4-BMC), ethylone (MDEC), MDPV (methylenedioxypyrovalerone) and buphedrone and it is possible that other compounds are in circulation.
