4F-MPH has an extremely short history of [[recreational drug use|recreational use]] and has yet to be documented being sold on the streets. It was initially developed as a replacement for [[ethylphenidate]] which became illegal in the United Kingdom on April 2015 following a temporary blanket ban. Shortly after, it ~~recently~~ became ~~made~~ available for sale on the online gray market as a [[research chemical]] for global distribution.

It was initially developed as a replacement for [[ethylphenidate]] which became illegal in the United Kingdom on April 2015 following a temporary blanket ban. Shortly after, it became available for sale on the online gray market as a [[research chemical]] for global distribution.

Due to its potent, long-lasting stimulant effect, likely habit-forming properties as well as unknown toxicity profile, it is strongly recommended that one use proper [[harm reduction]] practices if choosing to use this substance.
