Injection rooms exist in a number of countries. The first opened in Switzerland in 1986, and since then Australia, Norway, Spain, Germany and others have followed suit.
Accepting injection rooms as a legitimate part of drug strategy is hard for Berner to comprehend.
"It's more humane to help a person stay stupid? To help a person stay enslaved? You don't need to have heroin or needles or crack pipe kits to entice people to health. You could approach people and say, "let me look at that sore. I'm a nurse. Let's clean you up a bit.""

"I'm entitled to healthcare, and being treated like a human being, and not being looked at as somebody that isn't, somebody you don't want to talk about, like a dirty little secret.
