Despite efforts to reduce drug consumption in the United States over the past 35 years, drugs are just as cheap and available as they have ever been. Cocaine, heroin, and methamphetamines continue to cause great harm in the country, particularly in minority communities in the major cities. Marijuana use remains a part of adolescent development for about half of the country's young people, although there is controversy about the extent of its harm. Given the persistence of drug demand in the face of lengthy and expensive efforts to control the markets, the National Institute of Justice asked the National Research Council to undertake a study of current research on the demand for drugs in order to help better focus national efforts to reduce that demand. This study complements the 2003 book, Informing America's Policy on Illegal Drugs by giving more attention to the sources of demand and assessing the potential of demand-side interventions to make a substantial difference to the nation's drug problems. Understanding the Demand for Illegal Drugs therefore focuses tightly on demand models in the field of economics and evaluates the data needs for advancing this relatively undeveloped area of investigation.

This book analyzes the operation of illegal drug markets and explores the implications for prevention policy. Topics include crack distribution and abuse in New York, how young Britons obtain drugs, the impact of heroin prescription in Switzerland, the consumer behaviour of female drug users, heroin use and dealing in an English Asian community, Swedish drug markets and drug policy, performance management indicators and drug enforcement, connecting drug policy and research on drug markets. Contributors to this book are drawn from the UK, Europe and the USA.

The nightly news and other media provide a constant reminder of illegal drug transport over American borders and along routes between various U.S. cities. The general public is well aware that law enforcement efforts to address the foreign supply and trafficking of illegal drugs into the United States is an ongoing battle.This useful and readable compendium gives a fascinating account of how illegal drugs are transported into and around the United States and throughout its neighborhoods. Criminologist and geographer George F. Rengert takes a unique approach to the problem of illegal drug distribution and U.S. drug markets. Using maps and charts to illustrate his findings, Rengert applies spacial diffusion models to the illegal drug trade and explains why certain drugs are transported and found in different parts of the country. For example, the highest concentration of marijuana plants is not on either coast, but rather across the middle of the United States?throughout what is known as the corn belt. At the local level Rengert assesses the patterns and processes that interconnect drug sales and neighborhood deterioration and change.The book also addresses the important issues of how illegal drugs in this country operate on wholesale and retail levels and ways in which law enforcement at the federal, state, and local levels contend with this widespread problem. Using ethnographic material to provide real-life examples, Rengert explores how drug dealers on the street expand spatially and predictably in their neighborhoods. He illustrates how this knowledge helps law enforcement in efforts to get these drugs off the streets.

A sense of scale is a prerequisite to thinking sensibly about illicit drug markets. For example, knowing whether a country consumes tens, hundreds, or thousands of metric tons (MTs) of a prohibited substance is critical for understanding the impact of a three-MT seizure at a border crossing. But decision-makers need more than a sense of scale; they also need figures with enough precision to be able to determine whether the markets have become larger or smaller over time. This book provides information on what America's users spend on illegal drugs and which markets have become larger. It also discusses what heroin, cocaine, methamphetamine, and marijuana are and the consequences of drug use.

This book showcases recent advances in the theoretical and empirical understanding of the economic aspects of organised crime and illegal markets. It provides new insights into defining and quantifying the influence of organised crime by drawing on innovative approaches to studying criminal networks and organisations such as the Hells Angels. The book includes analysis of the structure of illegal drug markets from international leaders in the field. Finally the text includes empirical case studies of the diverse markets where organised crime is currently active including the illegal market for crystal methamphetamine in Australia, tiger products in China and the falcon and fur trades in Russia. This book was based on a special issue of Global Crime.
