3,4-Methylenedioxy-N,N-dimethylamphetamine (MDDM) is a lesser-known psychedelic drug. It is also the N,N-dimethyl analog of 3,4-methylenedioxyamphetamine (MDA). MDDM was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), the dosage is unspecified and the duration unknown. MDDM produces only mild effects that are not well characterized in PiHKAL. Very little data exists about the pharmacological properties, metabolism, and toxicity of MDDM. This compound is however occasionally encountered as an impurity in 3,4-methylenedioxy-N-methylamphetamine (MDMA) which has been synthesized by methylation of MDA using methylating reagents such as methyl iodide. An excess of reagent or a reaction temperature that is too high results in some double methylation of the amine nitrogen, yielding MDDM as well as MDMA. The presence of MDDM as an impurity can thus reveal which synthetic route was used to manufacture seized samples of MDMA. MDDM is also known as MDMMA, or as "sass" on the streets. This is in reference to the sassafrass plant from which MDDM can be derived.
