The relationship of this song to Babylon is not unlike that of the relationship of U2's Running to Stand Still to Bullet the Blue Sky, in my mind. While I personally doubt that these songs are about drug use specifically (though his Friday night enfant is never specified, and though the evidence toward the song referring to cocaine is strong), it's clear that there is a burst of some level of emotion at the beginning of the story and a level of coming-down at the end.
I always assumed that the "chemicals running through [his] bloodstream" are adrenalin, or caffeine, or perhaps alcohol, or maybe not chemicals at all but instead the personification of the rush of emotion that comes all at once in these sorts of situations.
