Lyric discussion by foolwhoknows1 

First, it's definitely a drug song. "Only you and what I found" is key to that. The Dan is never so obvious as to make the song about the surface meaning (sex), although all the double entendres make it all that much better.

Second, the posted lyric is wrong: it's "the spoor is on the wind tonight" which is a hunting/tracking reference and actually makes sense, as opposed to "spore". (Again, drugs and sex both work with that reference).

And if you listen carefully, he definitely says Snake Mary, not Saint Mary (though that would make sense from a lyric perspective).

@foolwhoknows1 Plus, as it not-so-surprisingly turns out, cannabis is in the rose family of flowering plants. Your interpretation is spot-on and I feel like I even heard Fagen say as much in an interview years ago.
