Some countries develop illegal drugs industries, and others do not. Discerning the distinguishing characteristics-social, economic, and political-of countries with these industries forms the subject of this sophisticated and humane study. The author, Francisco E. Thoumi, though trained as an economist, rejects simplistic economic solutions as well as simplistic moral ones as he addresses the Andean countries of Peru, Colombia, and Bolivia and the attitudes and responses of the United States. He investigates how the United States and the Andean countries perceive drugs issues; the history, structure, and evolution of drug industries in the Andes; the size of the industries in Peru, Colombia, and Bolivia; and their economic, political, and social effects in each country. Thoumi also addresses the political systems and social characteristics of these countries and why they have been so vulnerable to influence from these industries. And he offers case studies of a variety of anti-drug efforts including crop substitution and alternative development, eradication, interdiction of illicit traffic and manufacturing facilities, and extradition to the United States of traffickers.
