Dr Zeff was introduced to MDMA by Dr Alexander Shulgin. Zeff's response was wildly enthusiastic. He postponed his retirement and began to proselytise.
Dr Zeff introduced MDMA to hundreds of his fellow therapists across the USA. Zeff christened MDMA "Adam". The name was chosen because the drug typically strips away a lifetime of anxieties, self-protective inhibitions and ego defence-mechanisms - returning the user to an allegedly primordial state of innocence.
