3-FEA is the common name for 3-Fluoroethamphetamine which is a synthetic ring-substituted fluorinated amphetamine compound. It can give a mixture of entactogenic and stimulant effects if consumed. 3-FEA is structurally related to a series of fluorinated, substituted amphetamines, that originally included other compounds such as 2-FA, 2-FMA, 3-FA, 4-FMA, 4-FA.
3-FEA has a parent compound called 3-FA. The pharmacological, toxicological, and subjective effects of 3-FEA are similar to 3-FA. Early research reports suggest that 3-FEA as a moderately potent serotonin and norepinephrine-dominant triple monoamine releaser. It produces a medium-duration mixture of entactogenic and stimulating effects that skew more to the euphoric-recreational side, similar to one of its popular predecessors, 4-FA, than towards what some consider to be more functional or productivity-enhancing e.g. isopropylphenidate, 2-FA, or 2-FMA.
