Uncle Bill ‘fesses up about his heroin habit.
This interview from 1977 begins with William Burroughs replying to a question as to whether he had any regrets in using heroin?
A writer can profit from things that maybe just unpleasant or boring to someone else, because he uses those subsequently for material in writing. And I would say that the experience I had, that’s described in Junkie, later led to my subsequent books like Naked Lunch. So I don’t regret it. Incidentally, the damage to health is minimal—no matter what the American Narcotics Department may say.
Burroughs may have been clean at the time, but he returned to using Methadone in later life, which makes parts of this interview rather poignant.
