An Argument Against Drug TestingWelfare Recipients ABST RACT. Programs of drug resting welfare recipients are increasingly common in US states and have been consider d elsewhere. Though often intensely debated, such programs are complicated .to evaluate because their aims are ambiguous-aims like saving money may be in tension with aims like referring people to treatment. We assess such programs using a proportionality approach, which requires that for ethical acceptability a practice must be reasonably likely to meet its aims, sufficiently important in purpose as to outweigh harms incurred, and lower in costs than feasible alternatives. In the light of empirical findings, we argue that the programs fail the three requirements. Pursuing recreational drug users is not important in the light of coses incurred, while dependent users who may require referral are usually identifiable without testing and typically need a broader approach than one focussing on drugs. Drug testing of welfare recipients is therefore not ethically acceptable policy.P rograms of drug testing welfare recipients have been introduced in a number of states of the USA and in New Zealand. The practice has also been proposed but not implemented in Canada and the United Kingdom (Wincup 2014). Recently, legislation was prepared to introduce drug testing of welfare recipients in Australia, and more US states have drafted legislation. Stated aims of these programs include: to identify people with drug problems in order to refer them to treatment, with the longer-term aim of facilitating their gaining employment; to prevent welfare payments being spent on illicit substances; and protecting the children of people dependent on drugs (see, e.g., Bolen 2014, 86; Schaberg 2012, 575). Bur these different aims imply quite different responses to drug test results, and ambiguity surrounding what these programs aim to do compLicates attempts to evaluate their success.
