This course is divided into two segments. The first segment of the course covers illegal drug markets along their entire transaction chain from the growing regions of Latin America and Asia to the end-user markets. Emphasis is placed on the international markets for cocaine, heroin, and methamphetamines, and the negative impacts of trafficking and use. The second segment examines the cost-effectiveness and viability of different supply and demand strategies, ranging from crop eradication and border interdiction to treatment and prevention.
