In Amsterdam’s cafes, you can buy hashish openly, over the counter. But go around back to see how the drug comes in, and you’ll get a lot of smoke blown in your face. The entire supply chain is illegal. BBC Arabic’s Emir Nader holds his breath and traces it thousands of kilometres back to the mountains of Morocco, where cannabis is grown and processed into bricks of hash. There, he finds farmers in poverty and officials claiming "there is no organised crime" in the country. In between, he joins Spanish police as they knock down doors looking for the drug and meets a former smuggler who explains how for years he eluded Europe’s authorities to bring in millions of dollars’ worth of Moroccan hash.
