Pierre-Arnaud Chouvy / 2006 / High Times.
A geographer and research fellow at the CNRS in France, Dr. Pierre-Arnaud Chouvy spent years studying opium production in Asia—from Afghanistan to Burma—before visiting Morocco to observe how cannabis and hashish production compares with opium farming. He traveled through the Rif Mountains of northern Morocco in August 2005, during late cannabis harvest time, eventually reaching the legendary town of Ketama, where the world-famous hashish of the same name originates.
