An amphetamine derivative, MDMA reduces inhibitions, creating a sense of intimacy and the desire to speak about your inmost feelings. Some psychiatrists therefore used it in the 1980s to assist hypnosis, even though it was not approved by the FDA.
此種安非他命類衍生物，因能去除人的防衛心，讓人產生親密感、暢所欲言，雖未通過美國 FDA 的核准，但 1980 年代曾被用作精神治療，做為催眠時的輔助劑。
