The effectiveness of compulsory drug treatment: A systematic review

The_effectiveness_of_compulsory_drug_treatment-_A_systematic_review.jpgFebruary 2016: This study published in the International Journal of Drug Policy (IJDP) finds that evidence does not, on the whole, suggest improved outcomes related to compulsory treatment approaches, with some studies suggesting potential harms. Given the potential for human rights abuses within compulsory treatment settings, non-compulsory treatment modalities should be prioritized by policymakers seeking to reduce drug-related harms.

A Call for A Reprioritization of Metrics to Evaluate Illicit Drug Policy

Open_Letter_Cover_Page.png

January 21, 2016: Scientific experts from around the world are calling on governments to better align illicit drug policy goals with community concerns. This open letter outlines extensive scientific evidence that the indicators used to evaluate drug policy ignore some of the most important community impacts. In response, the open letter includes a preliminary set of suggested indicators that allow for governments to better assess the health, security, development and human rights impacts of their drug policies. By reprioritizing the indicators used to evaluate illicit drug policy, governments will be better able to implement targeted and effective policies that align with community needs. The alternative is to continue the unacceptably high levels of drug-related harms, with grave implications for communities across the globe.

State of the Evidence: Cannabis Use and Regulation

Screen_Shot_2015-08-11_at_12.22.58_PM.png

August 2015 (Updated on September 7, 2015): This report provides a comprehensive overview of the scientific research on major claims made about cannabis use and regulation. For each claim, the relevant available scientific evidence is presented and the strength of the scientific evidence in support of the claim is determined. 

LINKS: [FULL REPORT] [METHODOLOGY] [PRESS RELEASE] [CAMPAIGN]
[CANNABIS USE CLAIMS SUMMARY CHART] [CANNABIS REGULATION CLAIMS SUMMARY CHART

Readers will notice that none of the claims are strongly supported by the scientific evidence, reinforcing the significant misrepresentation of evidence on cannabis use and regulation. The ICSDP hopes that the evidence contained in this report meaningfully contributes to the global conversation around cannabis policy and helps policymakers, as well as general readers, separate scientific evidence from conjecture.

Please note that this report should be read in tandem with Using Evidence to Talk About Cannabis, a complementary guide to having evidence-based discussions on cannabis use and regulation.

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

All_Website_SupplyReduction_Paper_front_page.pngSeptember 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.

LINKS: [STUDY] [BACKGROUNDER] [PRESS RELEASE]

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

Effectiveness_of_anti-illict_drug_PSAs_JECH.png

April 2011: This study 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.

LINKS: [STUDY]

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

 

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

TOOLS_FOR_DEBATE_COVER_SHOT.jpgOctober 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.

LINKS: [REPORT] [FACT SHEET] [POWERPOINT] [VIDEO] [PRESS RELEASE

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.

The Vienna Declaration

Vienna_Declaration_Lancet.png

June 2010: 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.

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

ICSDP_Violence_Report_-_front_cover.jpgApril 2010: This report consists of a scientific review that illustrates the relationship between drug law enforcement and drug-related violence. In March 2011, this report was published in the International Journal on Drug Policy (IJDP). 

LINKS: [REPORT] [IJDP PUBLICATION] [FACT SHEET] [PRESS RELEASE] [VIDEO]

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.
