4-Fluoromethamphetamine (4-FMA) is a stimulant drug related to methamphetamine and 4-fluoroamphetamine. It has been reported to be sold on the illicit market as a controlled substance analogue, but little is known about its pharmacology or toxicology as yet. It was first defected from legal highs sold in Japan in 2006 and became illegal to sell or to possess for the purpose of distribution (it's significant that not illegal to possess for personal use only) in Japan in 2008. It was initially reported to be contained as an ingredient in some of the range of party pills sold internationally by the Israeli company Neorganics from around 2006 onwards, but this was later shown to be incorrect and this ingredient was eventually identified as the closely related compound 2-fluoromethamphetamine.
