EMDA-2
EMDA-2, also known as 2-ethoxy-4,5-methylenedioxyamphetamine, is a psychedelic drug of the phenethylamine and methylenedioxyamphetamine families. It is the analogue of MMDA-2 in which the 2-methoxy group has been replaced with a 2-ethoxy group. This has resulted in EMDA-2 being described as the "TWEETIO" analogue of MMDA-2.EMDA-2's dose is approximately 135 to 185mg and its duration is about 10 to 12hours. At 135mg, it produced closed [eye visual]s, including intense colors, with sleep disturbances and a duration of some 10hours. At 185mg, its effects were stronger, including "marvelous" closed-eye visuals with "incredible" colors, good concentration, and distinct body tingles and rushes, with insomnia and a duration of about 12hours. The potency of EMDA-2 is about one-third that of MMDA-2.Interactions
