MBDB, or 3,4-methylenedioxy-alpha-ethyl-N-methylphenethylamine, is a lesser-known hallucinogenic phenethylamine. It is also known as "EDEN" or "Methyl-J." It is the alpha-ethyl-N-methyl analog of MDMA (Esctasy). It was first synthesized by David E. Nichols, a leading pharmacologist and chemist, and later tested by Alexander Shulgin and written up in his book, PiHKAL (Phenethylamines I Have Known and Loved). MBDB's dosage, according to PiHKAL, is 180-210 mg; the proper dosage relative to body mass seems unknown. Its duration is 4-6 hours, with noticeable after-effects lasting for 1-3 hours.

MBDB causes many mild, MDMA-like effects, such as lowering of social barriers and inhibitions, a pronounced sense of empathy and compassion, and mild happiness, euphoria, and enhanced emotions are all present. However, MBDB's effects are much less profound then those of MDMA. MBDM's effects tend to produce less euphoria, less psychedelia, and have less stimulative properties than MDMA does. Many users declare that MBDB is a "watered-down" version of MDMA as MBDB loses action much more quickly, due to the milder effects, lack of a "rush," and its sedative effects. As with MDMA, users are at risk for acute dehydration if participating in strenuous physical activity and forget to drink water, as the drug may mask one's normal sense of exhaustion and thirst.


  • MAOIs, specifically MAO-A inhibitors and non-selective MAOIs may precipitate serotonin syndrome when combined with MBDB.
  • Driving and operating heavy machinery may be especially hazardous as MBDB has a fairly pronounced sedative action.
