4-FMP, also known by its full chemical name 4-fluoroamphetamine, or 4-Fluoro-alpha-Methyl-Phenethylamine, is a central nervous system stimulant. It is a chemical analog of amphetamine, and is also related to other phenethylamines, such as cathinone, methcathinone, and methamphetamine.


4-FMP has a very short history of human use, so not much is known about its pharmacological effects, as is the case with many other designer drugs.

4-FMP clearly has an amphetamine type of effect on the central nervous system. The halogenated compound clearly shows a mild serotogenic release in the user. 4-FMP when insufflated is extremely painful and this way of administration should be avoided. It is noted that this compound doesn't have a harsh come down like other CNS stimulants.

Effects include euphoria, increased energy, and suppressed appitite. It also inhibits the ability to sleep, like most stimulants.
