Imagine a caffeinated concoction that, when ingested, resulted in bouts of vomiting. You might prefer to stick with your gourmet coffee.
But the "Black Drink" as it is known was part of a ritual. The vomiting was done for purity. It turns out, early societies imbibed. Even the Cahokia civilization about 1000 years ago. That's roughly 500 years earlier than records of consumption elsewhere. Research has found residue in ceremonial cups that confirm the Black Drink was used at Cahokia.
