Cover art for Mind Eraser, No Chaser lyrics by Them Crooked Vultures

This song seems to be about drug abuse as a means of escapism. The idea of amnesia in a pill is the most obvious reference, but it hardly ends there. The most subtle is probably "Dulling the edge of a razor blade," in my mind, refers to the act of cutting up a drug into lines of powder to snort it. I can't really think of another action that one would willingly use a razor blade for that would cause it to significantly dull, outside of its intended use of course.
