Burroughs and His Shoe
"Some of my learned colleagues (nameless assholes)have suggested that junk derives its euphoric effectfrom direct stimulation of the orgasm center. It seems more probable that junk suspends the whole cycle of tension, discharge and rest. The orgasm has no function
in the junky. Boredom, which always indicates an un-discharged tension, never troubles the addict. He can look at his shoe for eight hours. He is only roused to action when the hourglass of junk runs out."
