I arrived in Lima, Peru last Tuesday. I didn´t pick anything up in Lima because of all the police... But when I got to Cusco, everyone wants to sell you cocaine or weed, or anything else you might want... My first bag was literally moss. The second I actually looked at before I bought it and it was decent. If you´re in south america, they´ll give you the price, offer them half, and see what happens. If they don´t lower the price, walk away.
