Background: Substance use disorder, unemployment, and poverty are interrelated problems that have not been addressed adequately by existing interventions. This study evaluated post-intervention effects of abstinence-contingent wage supplements on drug abstinence and employment.
Methods: Unemployed adults enrolled in opioid agonist treatment were randomly assigned to an abstinence-contingent wage supplement group (n = 44) or a usual care control group (n = 47). All participants could work with an employment specialist throughout a 12-month intervention period. Those in the abstinence-contingent wage supplement group earned stipends for working with the employment specialist and, after gaining employment, abstinence-contingent wage supplements for working in their community job but had to provide opiate- and cocaine-negative urine samples to maximize pay. To assess post-intervention effects of abstinence-contingent wage supplements and compare those effects to during-intervention effects, we analyzed urine samples and self-reports every 3 months during the 12-month intervention and the 12-month post-intervention period.
Results: During the intervention, abstinence-contingent wage supplement participants provided significantly more opiate- and cocaine-negative urine samples than usual care control participants; abstinence-contingent wage supplement participants were also significantly more likely to become employed and live out of poverty than usual care participants during intervention. During the post-intervention period, the abstinence-contingent wage supplement and usual care control groups had similar rates of drug abstinence, similar levels of employment, and similar proportions living out of poverty.
Conclusions: Long-term delivery of abstinence-contingent wage supplements can promote drug abstinence and employment, but many patients relapse to drug use and cease employment when wage supplements are discontinued.

Background: Alcohol use disorder, unemployment, and risk of homelessness are linked and often co-occurring, but most interventions do not address both alcohol use disorder and unemployment. The Abstinence-Contingent Wage Supplement (ACWS) model of the Therapeutic Workplace offers participants stipends or wage supplements contingent on both their abstaining from alcohol and engaging with an employment specialist or working in a community job. Wearable biosensors continuously tracked alcohol use.
