Julio Calzada, drug czar of Uruguay: “We had begun working with a low tax; now we have a flexible tax, which will be able to move. Our law allows for that, and at least our low tax – that’s what allows us to compete with the black market. Eventually as the legal market develops and grows we could raise taxes.” here or at https://vimeo.com/130489985 at the 40’24” mark
UPDATE: Bryce Pardo says that rates have not been set yet. So I guess this statement indicates intention rather than fact. If you listen to the Spanish, Impuestos = taxes.
