How do effects, potency and chemical structure compare with MDMA?
MBDB has, in general, effects similar to MDMA. However, it is my impression that the nature of the effects with MBDB is much more variable. Some individuals reported that they experienced effects almost identical to MDMA, while others found the substance even dysphoric. Clearly, on average, the compound does not produce the degree of euphoria, and feeling good, that is produced by MDMA. This has not been accurately quantitated, but is probably evidenced by the fact that there has been relatively little trade in this substance in the decade since its report. The potency is also somewhat lower. 125 mg of MDMA would be similar to perhaps 175 mg of MBDB. These are just “ball park” guesses. The chemical structure differs from MDMA slightly. The side chain of MDMA has a methyl group attached to the alpha position, while the side chain of MBDB has an ethyl. Otherwise, the structures are the same.
