Is it possible Cocoa grew in N. Africa 14K years ago? It was cooler and wetter then.
Botanists are pretty adamant that the Coca plant is indigenous to Peru and South America at least. Not too sure about Tobacco - but neither should have been available to Egyptians. Supposedly high trace levels have been found in ancient mummies. Not too sure how accurate that claim is.
Maybe but, no-one has ever found any traces of it.
