Heroine.

You've made yourself a commodity
You've made a shroud of vanity
But those two things need not be related

A little snort keeps me going
From beforehand to the evening
A little anticipation stops me from going mad

Oh, but I'm already mad
I suppose that's your doing too
And yet somehow I'm glad of it

What was that Lou Reed said?
A needle to the vein
Makes me right in the head
