In the Journal of Psychedelic Drugs (vol. 11, p. 78), Dr. Jose Luis Diaz from the University of Mexico presents suggestive but uncertified evidence that marijuana may have been known to the Ndhuas and other New World tribes before the arrival of the Spaniards. Whether or not Cannabis was growing in the Americas already, the Spanish seem to have taken their own to Chile in 1545 and then to Peru in 1554.
