The drug war in Latin America has received an increasing amount of funds and resources since it began nearly four decades ago. Recent efforts by the United States and Mexico to combat illegal narcotics traffickers have gained increased attention in the wake of September 2001 terrorist attacks. Similar efforts by the United States have been tried in the past, particularly in Colombia, with varied levels of success. This increased level of attention runs in counterpoint to the continued vitality of the drug trade, as markets expand and consumption remains steady. Violence resulting from drug trafficking organizations (DTOs) in Mexico has produced an even greater sense of urgency for both nations to respond to this threat. The latest plan to combat DTOs and the drug trade, the Merida Initiative, has gained high visibility and shows promise at providing an adequate solution. This book will discuss the effectiveness of the Merida Initiative and its ability to impact the trafficking of illegal narcotics in the United States and Latin America. Likewise, we will use the Merida Initiative as an example of modern supply-side practices, to evaluate the overall effect of such actions affecting price and consumption of illegal narcotics."
