MDPHP (3',4'-Methylenedioxy-α-pyrrolidinohexiophenone) is a stimulant of the cathinone class originally developed in the 1960s,[1] which has been reported as a novel designer drug. In the UK its slang name is monkey dust.[2] It is closely related to the potent stimulant MDPV though with slightly milder effects, and has been used as an alternative in some countries following the banning of MDPV.[3][4][5][6]

Legal Status[edit]

MDPHP is specifically listed as a controlled substance in Japan [7] and Hungary,[8] and is controlled under analogue provisions in a number of other jurisdictions.
