4-Fluoroamphetamine, para-fluoroamphetamine. 4-FA, or 4-FMP, 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-Fluoroamphetamine has a very short history of human use and is very uncommon so therefore little is known about its pharmacological effects, as is the case with many other designer drugs.

4-Fluoroamphetamine clearly has an amphetamine type of effect on the central nervous system. The halogenated compound also shows a mild serotogenic release in the user giving it a very slight resemblance to MDMA, it also differs from other halogenated amphetamines in that it is not known to be as neurotoxic compared with para-chloroamphetamine, para-bromoamphetamine and para-iodoamphetamine. It is noted that the potency of 4-FMP is roughly 2/3 that of dextroamphetamine.

Effects include euphoria, increased energy, mood elevation, excessive talking, bruxism (jaw clenching) and suppressed appetite. It also inhibits the ability to sleep, like most stimulants.
