Just a question though, back to the subject of the song, every line is addressed to 'baby' or 'daddy' and he talks about himself in the third person "he got flack, baby" "He's taking demerol" and then switches to 1st person "I ain't your rival".
even if you allow that some of this is being addressed to the drug or by the drug, it seems like 'baby' and 'daddy' imply a woman as a subtext, no? how else do you interpret it?
