1P-MiPLA, also known as 1-propanoyl-lysergic acid methylisopropylamide (1-propanoyl-MiPLA), is a designer drug and presumed serotonergic psychedelic of the lysergamide family related to lysergic acid diethylamide (LSD). It is the 1-propanoyl derivative of MiPLA and may act as a prodrug of MiPLA. 1P-MiPLA has been discussed on specialized online forums since 2018. In addition, a designer drug product labeled "1P-MiPLA" but actually containing MiPLA was encountered in Austria in 2019.
1P-MiPLA is a controlled substance in Canada under phenethylamine blanket-ban language.
1P-MiPLA is not an explicitly controlled substance in the United States. However, it could be considered a controlled substance under the Federal Analogue Act if intended for human consumption.
