4-FA (4-fluoramphetamine) is an amphetamine-like drug that has only appeared on the Dutch market for a relatively short time. In the period from 2007 to 2009 it was mainly sold as speed or MDMA. This was because at the time there was a shortage of raw materials for these agents, so 4-FA was used as a cutting agent. However, since 2010, 4-FA has been increasingly sold as 4-FA by dealers, which also means that consumers see it as a “drug of choice”.
Other names for 4-FA include 4-FMP, 4-Fluor, 4-Flava, 4-F or Flux. It is a substance that falls under the new psychoactive substances (NPS). These are substances that have only recently been on the market and have been developed as an alternative to conventional illegal substances. NPS is also known as research chemicals or designer drugs. By changing something small to an existing chemical structure, the substance name changes and is therefore no longer covered by the Opium Act and thus illegal. This makes it more difficult to prevent production, sales, and ownership.
