This is a terrible tutorial on how to use coca leaves in Northern Argentina. http://www.tourist2townie.com/ has enough trouble just pronouncing the names of the towns yet alone properly explaining one of the most traditional aspects of the culture in Northern Argentina... coca leaves. However, my heart was in the right place and luckily I had help from a beautiful Argentine and all the friendly people from the region. Shout out to all my peeps in Tilcara, Iruya, Humahuaca, Salta, Purmamarca, Cachi, and Cafayate.
