Halogenated amphetamines, including 4-fluoroamphetamine (4-FA), are psychostimulatory designer drugs which inhibit the uptake of monoamine neurotransmitters. 2-Fluoroamphetamine (2-FA) (hydrochloride) is a structural isomer of 4-FA, having the fluorine at the 2, rather than the 4, position. The physiological and toxicological properties of 2-FA are not known. This product is intended for research and forensic applications.
2-Fluoromethamphetamine (2-FMA) is a phenethylamine and amphetamine that’s been used since around 2012. It’s a research chemical and little formal knowledge about the substance is available.
It’s been described as an alternative to amphetamine and lisdexamfetamine, albeit with a lower recreational potential. 2-FMA primarily offers productive rather than recreational effects. Most users describe it as less inherently recreational than amphetamine. The replacement of a hydrogen atom with a fluorine atom in certain compounds to facilitate passage through the blood–brain barrier, as is desirable in central nervous system pharmaceutical agents, is a common practice due to the corresponding increase in lipophilicity granted by the substitute.
