4,4'-Dimethylaminorex (abbreviated as 4,4'-DMAR), sometimes referred to by the street name "Serotoni", is a psychostimulant and entactogen designer drug related to aminorex, 4-methylaminorex, and pemoline.^[3] It was first detected in the Netherlands in December 2012,^[4] and has been sold as a designer drug around Europe since mid-2013.

4,4'-DMAR had been linked to at least 31 deaths in Hungary, Poland, and the UK by February 2014, mostly when consumed in combination with other drugs.^[5] Nineteen deaths linked to 4,4'-DMAR were reported in Northern Ireland in the same time period.^[6]
