Poetry is a mere drug, Sir.

Taken at face value, the line treats poetry not as nourishment or moral instruction but as a stimulant—something consumed for effect rather than substance. Calling it “a mere drug” implies poetry can intoxicate, distract, or soothe, offering temporary emotional relief while potentially weakening judgment or encouraging escapism. The honorific “Sir” suggests a social exchange—likely a character speaking with pointed wit—so the remark also reads as satirical commentary on fashionable literary taste: poetry as a commodity for pleasure, not truth. In Farquhar’s comic-dramatic world, such a sentiment would fit a skeptical, worldly voice puncturing romantic or high-minded pretensions.
