4-Methylethcathinone or 4-MEC is a chemical that bears a chemical resemblance to mephedrone. Due to its similarity to mephedrone, it is thought to be a stimulant and entactogen drug of the phenethylamine, amphetamine, and cathinone chemical classes.
Also, it has been marketed alone or in mixtures with other substituted cathinones under the name "NRG-2".However, other blends such as "NRG-1" may have been more ambiguous with their ingredients.
4-MEC is reported to have been used as the active ingredient in fake "Ecstasy" pills in some countries such as New Zealand.

Pharmacology of of 4-MEC
4-MEC is a synthetic stimulant with empathogenic effects that is chemically similar to methcathinone. Thus, it became available online in 2010 and has been sold as replacement for 4-methylmethcathinone (mephedrone).
Also has an extremely short history of human use. As of 2011, it is most often found as a powder and has appeared in some samples of "NRG-2", although it has also been found in tablet form.
Some reports of 4-methylethcathinone use involve redosing ("boosting" or "bumping") multiple times. Users sometimes mix oral and insufflated, taking some 4-methylethcathinone orally, then insufflating some, then taking more orally. However, because of the common desire to recapture the pleasurable initial high, redoses are sometimes higher than the initial dose. Also, the redoses can be spaced closely together in time.
Many users report having difficulty not redosing after using a strong dose if more 4-methylethcathinone is available when they are starting to come down. Experience reports in which users find themselves unexpectedly consuming a gram or more of 4-methylethcathinone are common.
