EMM, or 2-ethoxy-4,5-dimethoxyamphetamine, is a lesser-known psychedelic drug. It is a dimethoxy-ethoxy analog of TMA-2. EMM was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), both the dosage and duration are unknown. EMM produces few to no effects. Very little data exists about the pharmacological properties, metabolism, and toxicity of EMM.
