Methiopropamine (MPA), also known as '''N-methylthiopropamine''', is an organic compound structurally related to methamphetamine. Originally reported in 1942, the molecule consists of a thiophene group with an alkyl amine substituent at the 2-position. It appeared for public sale in the United Kingdom in December 2010 as a "research chemical" or "legal high", recently branded as Blow. It has limited popularity as a recreational stimulant.

==Pharmacology== Methiopropamine functions as a norepinephrine–dopamine reuptake inhibitor (NDRI) that is approximately 1.85 times more selective for norepinephrine than dopamine. It is approximately one-third as potent as dextroamphetamine as a norepinephrine reuptake inhibitor and one-fifth as much as a dopamine reuptake inhibitor. It displays negligible activity as a serotonin reuptake inhibitor.
