It's a derivative of phenmetrazine, aka Preludin which apparently was widely used from the 1950s. The Beatles were known to be fans of it.
Looks like 3-fpm was synthesised recently, Patents filed around 2011. I guess it was available for a while as an RC. Then mostly banned in the last 5 years or so.
And yeah, i guess it's me who's thinking of it
Some interesting quotes about phenmetrazine i found:
"In clinical use, phenmetrazine produces less
nervousness, hyperexcitability,
euphoria and
insomnia than drugs of the amphetamine family.."
"When stimulant use first became prevalent in Sweden in the 1950s, phenmetrazine was preferred to
amphetamine and
methamphetamine by users.
[12] In the autobiographical novel
Rush by
Kim Wozencraft, intravenous phenmetrazine is described as the most euphoric and pro-sexual of the stimulants the author used."
