“Wouldn't it be great,as Scott Peck suggests, if all medical students had to undergo the symptoms and feeling of a spectrum of illnesses. From acute infections to terminal cancer - and Kuru, the laughing sickness. Just a month for each exposure, controlled of course, and a good heavy dose of excruciating pain. So they'll know what that feels like.”

“A doctor is not criticized for describing the manifestations and symptoms of an illness, even though the symptoms may be disgusting. I feel that a writer has the right to the same freedom In fact, I think that the time has come for the line between literature and science, a purely arbitrary line, to be erased.”

“In homosexual sex you know exactly what the other person is feeling, so you are identifying with the other person completely. In heterosexual sex you have no idea what the other person is feeling.”

“The unworthies in power feel danger, like cows uneasily pawing the ground with a great "Moo.”

“I had the feeling that some horrible image was just beyond the field of vision, moving, as I turned my head, so that I never quite saw it.”

“The question is frequently asked: Why does a man become a drug addict?The answer is that he usually does not intend to become an addict. You don’t wake up one morning and decide to be a drug addict. It takes at least three months’ shooting twice a day to get any habit at all. And you don’t really know what junk sickness is until you have had several habits. It took me almost six months to get my first habit, and then the withdrawal symptoms were mild. I think it no exaggeration to say it takes about a year and several hundred injections to make an addict.The questions, of course, could be asked: Why did you ever try narcotics? Why did you continue using it long enough to become an addict? You become a narcotics addict because you do not have strong motivations in the other direction. Junk wins by default. I tried it as a matter of curiosity. I drifted along taking shots when I could score. I ended up hooked. Most addicts I have talked to report a similar experience. They did not start using drugs for any reason they can remember. They just drifted along until they got hooked. If you have never been addicted, you can have no clear idea what it means to need junk with the addict’s special need. You don’t decide to be an addict. One morning you wake up sick and you’re an addict. (Junky, Prologue, p. xxxviii)”
