The actual results[1] are less scary: long-term, heavy cannabis use that begins in adolescence correlates with increased rates of psychological conditions and IQ decline.
Edit: To inject a personal anecdote: every time I travel to Europe, I see people my age (and sometimes substantially younger) drinking beer and smoking marijuana. I almost never see reckless drinking or smoking the way I do in the US (e.g., at every college event), and I attribute that to a cultural failure of ours.
My opinion: if we want to stop the kinds of results that these studies show, then we should focus our efforts on reducing the taboos/absence of cultural knowledge that lead to binge usage.
