The vision of an expanding international market for legal coca products – such as flour, tea and ointments – is shared widely in Bolivia, and it was the driving force for a recent law signed this month by president Evo Morales that jacks up the 12,000 hectares (29,640 acres) legally recognized in a 1988 law to 22,000 hectares. But in most other countries, coca is still best known as the main ingredient in cocaine, and finding a legal market for alternative products has proved challenging.
