可以想成一種從罌粟做出來的藥。它強到能把很嚴重的痛推到感覺不到的地方。但它並沒有把傷治好。傷還在，只是你感覺不到了，而且人會變得昏昏欲睡。這個「把感覺蓋住、問題留著」的效果，正好是這個字所有用法的共同底。看懂這個畫面，藥的用法和罵人的比喻就會連成一條線。From the word’s history
Wiktionary traces opiate to Middle English opiate and Medieval Latin opiatus, the same family as opium.
根據 Wiktionary，opiate 來自中古英文 opiate，再往前是中世紀拉丁文 opiātus，和 opium（鴉片）同一家族。所以字的核心從一開始就綁在鴉片這個材料上。
