With the solitary exception of the Eskimos, there isn't a people on Earth who doesn't use psychoactive plants to effect a change in consciousness, and there probably never has been. As for the Eskimos, their exception only proves the rule: historically, Eskimos didn't use psychoactive plants because none of them will grow in the Arctic. (As soon as the white man introduced the Eskimo to fermented grain, he immediately joined the consciousness changers.) What this suggests is that the desire to alter one's experience of consciousness may be universal.
