The temporal relationship between drug supply indicators: an audit of international government surveillance systems

September 2013: This study published in the British Medical Journal Open finds that the prices of illegal drugs have generally declined while their purity has increased over the past twenty years, raising questions about the effectiveness of international law enforcement efforts to reduce drug supply. 


Researchers reviewed two decades of global drug surveillance data, finding that the supply of major illegal drugs has increased, as measured through a decline in the price, while there has been a corresponding general increase in the purity of illegal drugs.

The effectiveness of anti-illicit-drug public-service announcements: a systematic review and meta-analysis

April 2011: This report reviews existing studies on the effectiveness of anti-illicit-drug public service announcements (PSAs) and concludes that there is insufficient evidence that anti-illicit-drug PSAs are effective in reducing the intent to use illicit drugs amongst youth.


In an effort to reduce drug use by youth, governments across North America, the UK and Australia have been increasing funding for anti-illicit-drug PSAs. However, the effectiveness of these programs has not been systematically evaluated. Using existing evaluations of anti-illicit-drug PSAs this report analyzes the impact that PSAs have on the intention to use illicit drugs and levels of illicit drug use after exposure to PSAs.

The Vienna Declaration

The Vienna Declaration calls for an international commitment to evidence-based drug policy. Research has demonstrated that existing drug-law enforcement practices are not reducing health and social consequences of drug use, in fact drug related crime, violence continues to grow. Included in the report is the text of the Vienna Declaration as well as background information and highlights of the over 20,000 endorsements from academics, scientists, legal professionals, organizations and members of the public.


Tools for debate: U.S. federal government data on cannabis prohibition

October 2010 -
This report demonstrates the failure of U.S. marijuana prohibition and supports calls for evidence-based models to legalize and regulate the use of cannabis.


To date, an impact assessment of cannabis prohibition based on data derived through US federal government surveillance systems has been largely absent from international debates regarding the known impacts of cannabis prohibition and the potential impacts of a regulated (i.e., legal) market. Drawing upon cannabis surveillance systems funded by the US government, this report summarizes information about the impacts of US cannabis prohibition on cannabis seizures and arrests.

Effect of Drug Law Enforcement on Drug-Related Violence: Evidence from a Scientific Review

APRIL 2010 - This report consists of a scientific review that illustrates the relationship between drug law enforcement and drug-related violence.

Violence is among the primary concerns of communities around the world, and research from many settings has demonstrated clear links between violence and the illicit drug trade, particularly in urban settings. While violence has traditionally been framed as resulting from the effects of drugs on individual users (e.g., drug-induced psychosis), violence in drug markets and in drug-producing areas such as Mexico is increasingly understood as a means for drug gangs to gain or maintain a share of the lucrative illicit drug market.
