2-Fluoromethamphetamine (2-FMA) is a stimulant drug of the amphetamine family which has been used as a designer drug.[1][2][3] 2-FMA is commonly compared to lisdexamfetamine (Vyvanse), and dextroamphetamine due to its efficacy as a study or productivity aid.[citation needed] 2-FMA is purported to produce somewhat less euphoria than comparable amphetamines, likely due to its main mechanism of action consisting of norepinephrine reuptake inhibition.[4]

2-Fluoromethamphetamine is fluorinated analogue of methamphetamine, and is a regioisomer of 3-FMA and 4-FMA.

It does not activate the serotonin receptors, including 5-HT2A,[4] unlike most stimulant drugs of the amphetamine family.

Legal status


As of 1996, 2-FMA is a controlled substance in Canada, due to being an analog of methamphetamine.[5]


As of October 2015, 2-FMA is a controlled substance in China.[6]


As of 13 December 2014, 2-FMA is a controlled substance in Germany.[7] It is controlled under Anlage I BtMG (Narcotics Act, Schedule I).[8] Substances controlled under Anlage I BtMG are illegal to manufacture, possess, import, export, buy, sell, procure or dispense it without a license. Violations of the law are punishable by a fine or imprisonment for up to five years.[9]


As of July 2019, 2-FMA is a controlled substance in Ukraine (considered a narcotic).[10]

United States

As a close analog of scheduled controlled substance,[1] sale or possession of 2-FMA could be potentially be prosecuted under the Federal Analogue Act.[11]
