“Ambition is a drug that turns it's addicts into potential madmen.”

“Addiction isn't about using drugs. It's about what the drug does to your life.”

“Drug addicts driven to crime to finance their drug addiction are not often inclined toward violent crime. Violence requires all different kinds of energy, and most drug addicts like to expend their energy not on their professional crime but on what their professional crime lets them afford. Drug addicts are often burglars, therefore.”

“Curiosity is an addictive drug.”

“[T]he truth is that drug addicts have a disease. It only takes a short time in the streets to realize that out-of-control addiction is a medical problem, not a form of recreational or criminal behavior. And the more society treats drug addiction as a crime, the more money drug dealers will make "relieving" the suffering of the addicts.”

“It is impossible to understand addiction without asking what relief the addict finds, or hopes to find, in the drug or the addictive behaviour.”
