EMM (psychedelic)
EMM (2-ethoxy-4,5-dimethoxyamphetamine) is a lesser-known substituted amphetamine. It is a dimethoxy-ethoxy analog of trimethoxyamphetamine (TMA-2). EMM was first synthesized by Alexander Shulgin. In his book PiHKAL, 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. See also
