Peru, one of the world's leading producers and exporters of cocaine, has seen the illicit trade boom in recent years.

The industry's growth has prompted the country's government to plan an anti-drug campaign.

Some experts blame the authorities for not taking enough action to stop the drug trade, while poor coca farmers say the government's failure to help them economically has forced them to continue in the business.
