Welcome to the WhyProhibition Research Archive


Here you will find an ever increasing number of research studies, in full text, maintained by our research editorial board.

We endeavour to only provide the best research available, and unless otherwise noted, only use peer-review research.

The goal of this website is to make the evidence (i.e. peer reviewed journal articles and significant reports) that supports the drug policy reform movement, available to all. Our society as a whole needs to move away from the illusion that drug prohibition is either effective or helpful in any way and our goal is to show you the research evidence to prove this. The research articles available on this site document, with great clarity and repetition, both the failures of drug prohibition and the way forward. You are encouraged to download all these research articles, just articles on specific topics, or single documents.

Enforcement or Treatment? Modeling the Relative Efficacy of Alternatives for Controlling Cocaine

C. Peter Rydell, Jonathan P. Caulkins and Susan S. Everingham

Operations Research, Vol. 44, No. 5 (Sep. - Oct., 1996), pp. 687-695

This paper presents a model that estimates the relative cost-effectiveness of four cocaine-control programs: three "supply control" programs (source-country control, interdiction, and domestic enforcement) and a "demand control" program (treating heavy users). Treatment emerges as by far the most cost-effective, and sensitivity analyses show that this result is very robust.

The international drug control system in the post-Cold War era. Managing markets or fighting a war?

Robin Room; Angela Paglia
Drug and Alcohol Review, Volume 18, Issue 3 September 1999 , pages 305 - 315

Abstract
The core institutions and scope of the international drug control system are described. The system has grown in participation and particularly in scope and ambitions since it was studied in the early 1970s by Bruun and colleagues. Its premises are notably in conflict with the currently dominant ideologies of a free-market global economy although, as earlier, the United States plays a dominant role in the drug control system. At a time when it is seen as a failure in its primary aims both from inside and from outside, defenses of the system have ranged from rousing rhetorical appeals to efforts to "de-sensationalize" the issues.

he Illicit Drug Market : Paradoxical Effects of Law Enforcement Policies

S Poret, C Téjédo - European Journal of Political Economy, 2006

Abstract

In this paper we endogenize the horizontal structure of illicit drug markets. The key assumption is that the trafficker’s probability of detection depends on his/her market share. We show that a stricter law enforcement policy encourages traffickers to permit competitors into the market. Increasing deterrence reduces the quantities supplied by each trafficker but also induces new entry, which cancels out the decrease in individual production at the aggregated level. Equilibrium total quantity and criminal profit are independent of the law enforcement level.

Abstract:
The pattern of misdemeanor marijuana arrests in New York City since the introduction of "broken windows" policing in 1994 is remarkable. By the year 2000, arrests on misdemeanor charges of smoking marijuana in public view (MPV) had reached 51,267 for the city, up 2,670 percent from 1,851 arrests in 1994. In 2000, misdemeanor MPV arrests accounted for 15 percent of all felony and misdemeanor arrests in New York City and 92 percent of total marijuana-related arrests in the State of New York. In addition, the pattern of arrests disproportionately targeted African-Americans and Hispanics. Read more »

Abstract

This paper examines the relation between prohibitions and violence, using the historical behavior of the homicide rate in the United States. The results document that increases in enforcement of drug and alcohol prohibition have been associated with increases in the homicide rate, and auxiliary evidence suggests this positive correlation reflects a causal effect of prohibition enforcement on homicide. Controlling for other potential determinants of the homicide rate does not alter the conclusion that drug and alcohol prohibition have substantially raised the homicide rate in the U.S. over much of the past 100 years.

The Effect of Drug Prohibition on Drug Prices: Evidence from the Markets for Cocaine and Heroin

This paper examines the effect of drug prohibition on the black market prices of cocaine and heroin. The paper examines the ratio of retail to farmgate price for cocaine, heroin, and several legal goods, and it compares legal versus black market prices for cocaine and heroin. The results suggest that cocaine and heroin are substantially more expensive than they would be in a legalized market, but to a lesser degree than suggested in previous research.
