The official state beverage of Oklahoma is milk. Good, old fashioned milk. With 13.9% of adults drinking excessively, I don't buy it. Maybe they're talking about White Russians. That's pretty much just milk with vodka in it. It's the kind of drink you have when you're trying to hide your drinking problem. "Dad, this milk smells spoiled." / "Don't drink that! That's mine!"
Oklahomans throw it down when it comes to drinking according to these stats, though that alcohol related automotive deaths seem alarmingly high. You can't blame them after the whole dust bowl thing in the 1930s. Everyone pretty much fled the state. When they came back they must have been ready to party.
