Learn English – What’s your poison – origin

etymologyusage

The question "What's your poison?" is an informal way of asking someone what they would like to drink. Apparently it has been used in this way since the mid-1800s. I read recently that the word "poison" derives from the Latin word for drink (potio, which also gave us potable). It may be just an interesting coincidence that "poison" is being used with the ancient (harmless) meaning. Is there any evidence of the word being used with the harmless meaning in the centuries between?

Not according to the OED.

In an entry updated in 2006, it lists only two meanings as "literal uses": the ordinary meaning, which is also the oldest (recorded from 1225); and a slightly later, but obsolete, meaning "A drink prepared for a special purpose; a medicinal draught; a potion."

Under "extended uses" it lists "colloquial (originally U.S.). Alcoholic liquor; an alcoholic drink. Frequently in what's your poison?: what drink would you like?" from 1805, but no other uses without deadly connotations.
