5-Methylmethiopropamine

5-Methylmethiopropamine (5-MMPA, mephedrene) is a stimulant drug which is a ring-substituted derivative of methiopropamine. It is not a substituted cathinone derivative like mephedrone, as it lacks a ketone group at the β position of the aliphatic side chain, but instead more closely resembles substituted amphetamines. It has been sold as a designer drug, first being identified in Germany in June 2020.^[1][2][3]
