Abstract: This essay reviews many of the less considered consequences of the war on drugs, particularly the consequences for developing countries, and weighs them against the evidence that exists regarding the likely efficacy of current strategies to curb drug use and trade. The most important unintended consequences of drug prohibition are the following. First, the large demand for drugs, particularly in developed countries, generates the possibility of massive profits to potential drug providers. Since they cannot be organized freely and under the protection of the law, they resort to the formation of organized crime groups, using violence and corruption as their means of survival and expansion. In severe cases, the challenge to the state is such that public stability and safety are severely compromised. Second, prohibition and its derived illegal market imply the expropriation of endowments and resources used to produce and trade drugs. In many instances, this entails the transfer of wealth from poor to rich countries and from poor peasants to rich (and ruthless) traders. Third, criminalization can exacerbate the net health effects of drug use. These consequences are so pernicious that they call for a fundamental review of drug policy around the world.

This paper reviews the unintended consequences of the war on drugs, particularly for developing countries, and weighs them against the evidence regarding the efficacy of prohibition to curb drug use and trade. It reviews the available evidence and presents new results that indicate that prohibition has limited effects on drug prevalence and prices, most likely indicating a combination of inelastic drug demand (due to its addictive properties) and elastic supply responses (due to black markets). This should turn the focus to the unintended consequences of drug prohibition. First, the large demand for drugs, particularly in developed countries, generates the possibility of massive profits to potential drug providers. This leads to the formation of organized crime groups, which use violence and corruption as their means of survival and expansion and which, in severe cases, challenge the state and seriously compromise public stability and safety. Second, prohibition and its derived illegal market impose greater costs on farmers than on drug traffickers. In many instances, this entails the transfer of wealth from poor peasants to rich (and ruthless) traders. Third, criminalization can exacerbate the net health effects of drug use. These consequences are so pernicious that they call for a fundamental review of drug policy around the world.

Examines the sale and use of illegal drugs around the world, discussing the scale of the global drug trade, identifying some of the most widely known and used drugs, exploring the source and production of drugs, and looking at ways to reduce demand.
