In an interview with John Oliver in S04E04 of Last Week Tonight there's the exchange:
Dalai Lama: One of my previous visits in Mongolia, they drank a lot of Vodka [...] I suggested: Drink much less Vodka [...] instead of that, their traditional sort of drink, horse milk.
John Oliver: Wait, hold on. You tried to wean them off Vodka? By giving them horse milk?
Dalai Lama: Oh yes. They follow.
John Oliver: What?
Dalai Lama: Since then I think the majority of Mongolians: No longer any drink.
John Oliver: Hold on that is a huge claim. You cured Mongolians of alcoholism.
Dalai Lama: Yes.
John Oliver: Using horse milk?
Dalai Lama: Yes.
Did this story happen? Did the Dalai Lama convince the Mongolians to drink much less alcohol?
