Javier Lizarzaburu returns to his native Peru to see the effects of America's war on drugs. The USA is spending more than $140 million there this year to eradicate coca, the raw material from which cocaine is made. But coca production is on the increase and for the first time the coca farmers, led by their new leader, Nancy Obregon, are making their voices heard. Javier travels to a remote region in the Amazonian rainforest to meet Nancy and hear her case against the USA's policy and also to Washington to discuss the issue with top officials there.
