Michel Dussack

“It isn’t the drug that causes the harmful behavior—it’s the environment. An isolated rat will almost always become a junkie. A rat with a good life almost never will, no matter how many drugs you make available to him. As Bruce put it: he was realizing that addiction isn’t a disease. Addiction is an adaptation. It’s not you—it’s the cage you live in.”
― Johann Hari, Chasing the Scream: The First and Last Days of the War on Drugs
