What song can you think of that refers to drugs INDIRECTLY using metaphor or other allusion?
Steely Dan’s “Time Out of Mind” mentions “chasing the dragon” The Beatles’ “Lucy in the Sky with Diamonds” is widely believed to be drug related (Look at the capitalized letters in the title: LSD) It certainly has some psychedelic imagery that could be based on drug-induced hallucinations. The folk song “John Barleycorn Must Die”, recorded by Traffic on the album of the same name, is a metaphor for trying to give up liquor.
