"Once and for all, people must understand that addiction is a disease. It’s critical if we’re going to effectively prevent and treat addiction. Accepting that addiction is an illness will transform our approach to public policy, research, insurance, and criminality; it will change how we feel about addicts, and how they feel about themselves. There’s another essential reason why we must understand that addiction is an illness and not just bad behavior: We punish bad behavior. We treat illness."
