Is Stevie's Secret Love....cocaine?????

[skuncles]

Ok, totally wild thought I know, but do you suppose that Stevie's "Secret Love" is in fact cocaine? The time frame is right for when she would have started using. At that point it would have still been a brand new thing and at the same time would have been an "oh maybe I shouldn't be doing this" kind of thing.
Go thru the lyrics and it sort of makes sense. Ever since she's been talking about the song and how she says she has no idea who it's about, I've been thinking "maybe it's not about SOMEONE, but someTHING".
I know most of you will totally dismiss the idea, but who knows???
