3-Fluoroethamphetamine (also known as 3-FEA) is a novel ring-substituted amphetamine compound that produces a mixture of entactogenic and stimulant effects when administered. 3-FEA is structurally related to a series of designer fluorinated substituted amphetamines that originally included compounds such as 2-Fluoroamphetamine (2-FA), 2-Fluoro-4-methylamphetamine (2-FMA), 3-Fluoroamphetamine (3-FA), 4-Fluoro-amphetamine (4-FA), and 4-Fluoromethamphetamine (4-FMA). Anecdotal reports have characterized 3-FEA as a moderately potent serotonin-dominant triple monoamine releaser that produces a mixture of entactogenic and mild stimulating effects.

Chemistry

3-FEA, or 3-fluoroethamphetamine, is a synthetic molecule of the amphetamine chemical class. Molecules of the amphetamine class contain a phenethylamine core comprised of a phenyl ring bound to an amino (NH2) group through an ethyl chain substituted with a methyl group at Rα (i.e., amphetamines are alpha-methylated phenethylamines). 3-FEA is the 3-position fluorinated analog of ethylamphetamine (also known as ethamphetamine). It is also an analog of fenfluramine with the 3-trifluoromethyl group replaced with a 3-fluoro substituent.

Pharmacology

Although 3-FEA has not been formally studied on the same level as traditional amphetamines, it is currently assumed that, like other substituted amphetamines with substitutions at similar positions, it most likely acts primarily as a triple reuptake inhibitor and/or releaser of the monoamine neurotransmitters serotonin, dopamine, and norepinephrine.

It has been demonstrated that compared to the unsubstituted ethylamphetamine, 3-fluoroethamphetamine is a weaker releaser of dopamine but a stronger releaser of both serotonin and norepinephrine, producing the strongest reinforcing effects in animal studies out of a range of 3-substituted amphetamine derivatives tested, despite not being the most potent dopamine releaser.

This indicates that 3-FEA effectively increases the levels of all three major monoamine neurotransmitters—dopamine, norepinephrine, and serotonin—in the brain by acting as a releasing agent of said neurotransmitters and/or by binding to and partially blocking the transporter proteins that normally clear those molecules from the synaptic cleft after they have fulfilled their function of conducting a neural impulse. This transporter blockade allows these molecules to accumulate within core synaptic regions of the brain to extra-endogenous levels, resulting in a combination of relaxing, stimulating, disinhibiting, and euphoric effects associated with entactogenic substituted amphetamines such as MDMA or 4-FA.

Subjective Effects

Unlike its close analog 3-FA, which has been reported as being relatively functional and non-recreational, 3-FEA appears to produce effects more similar to another analog, 4-FA, which produces marked entactogenic effects. 3-FEA has also been reported to produce less stimulation compared to 4-FA to the degree that some users report it as being primarily sedating. This effect profile likely makes 3-FEA a poor candidate for functional use and better suited for recreational use in a manner similar to MDMA.
