34-Ethylidenedioxyamphetamine (EIDA) is a substituted derivative of methylenedioxyamphetamine (MDA) which was developed by David Nichols and coworkers in the course of research to determine the bulk tolerance around the benzodioxole portion of the MDA molecule. EIDA was found to produce similar effects to MDA in animals but with less than half the potency while the isopropylidinedioxy derivative (IPIDA IDA) did not substitute for MDA and instead had sedative and convulsant effects.
