MBDB
Basics
by Erowid
DESCRIPTION #
MBDB is a synthetic phenethylamine similar in structure and action to MDMA (Ecstasy). It is an entactogen, with the ability to facilitate a state of introspection, interpersonal communication and a pronounced sense of empathy and compassion.

MBDB has a slower and more gentle onset of action than MDMA, produces less euphoria, less psychedelic effects, and has less stimulant properties. Many people find MBDB less fun than MDMA because of its more subtle nature and lack of strong rush. MBDB is extremely uncommon, but has occasionally been found in "ecstasy" tablets in Europe.
Dose #
There is very little data on what preferred recreational or therapeutic dosages are, but they seem to fall somewhere in the range of 150-250 mg.

Ayahuasca also contains MAOIs (harmine and harmaline). MBDB and MAOIs are a potentially dangerous combination.
