The World Drug Report documents developments in global drug markets and tries to explain the factors that drive them. Its analysis of trends and emerging challenges informs national and international drug and crime priorities and policies, and provides a solid foundation of evidence for counternarcotics interventions. Drug markets and drug use patterns change rapidly, so measures to stop them must also be quick to adapt. Thus the more comprehensive the drug data we collect and the stronger our capacity to analyse the problem, the better prepared the international community will be to respond to new challenges.
