4-Fluoroamphetamine (4-FA; 4-FMP; PAL-303; "Flux"), also known as para-fluoroamphetamine (PFA) is a
Usage
4-FA is popular in the Netherlands where it is predominantly used for its specific effects (77% of users) rather than its legal status (18%).[4] 4-FA has become illegal since May 2017.[5]
Effects
The subjective effects of 4-fluoroamphetamine include euphoria which some find similar to the effects of MDMA and amphetamine,[4] increased energy (stimulation), mood elevation, feelings of warmth and empathy, excessive talking, bruxism, and suppressed appetite (anorexic). The general course of effects involves primarily empathogenic effects for the first few hours, which fades out as increased stimulation develops over the next several hours. [medical citation needed]
The
Common acute side effects are nausea, headaches, increased heart rate and insomnia.[medical citation needed]
Chemistry
4-FA reacts with reagent testing to give a semi-unique array of colors which can be used to aid its identification.
Reagent | Reaction color |
---|---|
Marquis | No reaction[7] |
Mandelin | Pale Blue[7][8] |
Liebermann | Orange[7][8] |
Froehde | Faint purple/brown[7] or no reaction. |
Pharmacology
4-Fluoroamphetamine is a
Regarding the metabolic fate of 4-FA, the C-F bond at the 4-position on the phenyl ring likely resists deactivation in the liver by
Neurotoxicity
4-FA does not cause long-lasting depletion of brain serotonin, unlike its analogs 4-CA and 4-BA.[12] This is thought to "reflect the inability of the fluoro-compound to be metabolized in the same way as the other haloamphetamines."[13]
Toxicology
The
Fluoroamphetamine (isomer not determined) in a capsule mixed with 25C-NBOMe was associated with three deaths in Melbourne in 2017.[21]
Legal status
As of October 2015, 4-FA is a controlled substance in China.[22] 4-FA is banned in the Czech Republic.[23] As of 25 May 2017 4-FA is a controlled substance in the Netherlands.[24] 4-FA is also controlled in Australia, Belgium, UK, Germany, Israel, Slovakia, Bulgaria, Chile, Brazil, Canada, Croatia, Sweden, New Zealand and France.[citation needed]
