Earlier quoted context omitted.
"AFAIK there have always been addicts in every culture." Surely you would agree that there the proportion of addicts varies by culture and society, that the US for example has a much higher proportion than many poorer nations? I don't know about the first comment's claim that lack of interpersonal relationship is the root cause, but a strong social component looks obvious to me.
Cite? Every nation has an underbelly. Poorer nations, those folks tend to die pretty fast though.
