Abstinence incentive effects in a short-term outpatient detoxification program . Despite being widely available , outpatient detoxification has limited efficacy as a stand-alone treatment . This study examined whether abstinence-contingent incentives would improve outcomes for patients entering outpatient opiate detoxification . Participants ( N = 211 ) received a 100 US dollars voucher on the last day of detoxification either contingent on opiate and cocaine abstinence or noncontingently . Urine samples were collected at intake , on Wednesday , Friday ( the last day of detoxification ) , and the following Monday . Among contingent-voucher participants , 31 % were drug-free on Friday compared with 18 % of noncontingent controls ( Z = 2.4 , p < .05 ) . Few ( 12-13 % ) participants tested negative on Monday . Results support the ability of vouchers to produce modest improvements in abstinence initiation rates during brief detoxification but suggest that additional interventions are needed to sustain improvements .
