rates after they are free from the immediate threat of jail are much lower than those not forced to undergo testing. If prohibition remains the law of the land, is there much else one could do to make illicit drugs less problematic for both users and so- ciety as a whole? The notion of "harm reduc- tion" acceptance of the practical limits of a free society to control drug consumption and to focus on cutting the harmful consequences of drug use has become the approach of choice in many Western countries. depressingly slight. Prevention remains a slo- gan and aspiration, rather than a set of proven programs. Treatment, while cost-effective in the sense that it is cheaper than incarceration, apparently can make only a modest difference in recidivism. And, as already noted, draco- nian enforcement to raise prices and reduce availability has failed abysmally. camp and an addiction-treatment center, is showing signs of a pragmatic move toward harm reduction. Even Iran, with its huge opium/heroin market and indifference to in- dividual rights, has tilted in this direction. asked access to clean needles, along with col- lection and destruction of used needles, min- imizes the risk that addicts will spread AIDS and hepatitis. A dozen countries, including the Netherlands, Australia, Norway, Denmark and Canada, offer these services as do 33 states in this country. dicts. This service has been available for her- oin addicts in Switzerland for 15 years and in the Netherlands for five. Legal access remains a niche program, however. While it brings large benefits for those enrolled, only 5 per- cent of the heroin-dependent population in Switzerland have chosen to enroll. MacCoun, a social psychologist at University of California (Berkeley), and I have argued that harm reduction is best seen as a bench- mark for judging policies and programs rather than a class of interventions. Indeed, harm re- duction is merely standard cost-benefit analy- sis applied to a policy area that has so far been left in the hands of true believers. Cost-benefit analysis requires that the decision maker list and value all of the consequences of the deci- sion, both positive and negative. Harm reduc- tion can be seen as analysis-lite, since it does not claim to be able to monetize all the bene- fits and costs. the effects of supply-side interventions are negative. For example, aerial spraying of Co- lombian coca fields has led to other fields being planted with coca, which itself causes se- rious damage to fragile ecosystems. Moreover, spraying is predictably inaccurate, so legiti- mate farmers are also hurt by it. And as Vanda Felbab-Brown, a fellow at the Brookings Insti- tution, shows in her forthcoming book, Shoot- ing Up: Counterinsurgency and the War on increases peasants' willingness to collaborate with insurgents like the Taliban, FARC and Shining Path. The benefits from spraying, however, are elusive, since the most one can |
