I don’t mean one test, I mean one set of findings from the same source. Even if we’re to believe some ancient traveler made it to the Americas and back, they would have had a hell of a time finding those three things in the (likely one unplanned) trip. Besides, cocaine is the result of modern chemistry! Tripanone is the base alkaloid, from which cocaine is derived.

So not only would these people have had to identify the narcotic value of cannabis, tobacco and coca, they’d have to figure out how to press hashish, and process large amounts of coca leaves for tripanone, and then process that into cocaine base. In practice getting significant quantities of cocaine from coca without the intermediate chemistry isn’t feasible.

No.
