There was no significant difference comparing the pre-treatment and post-treatment trends for cocaine, crack cocaine, crystal methamphetamine, and cannabis. However, higher growth slope was noted during the post-treatment period for daily alcohol use (P = 0.016). CONCLUSIONS We observed significant reduction in illicit opioids use following OAT initiation, but not for stimulant and cannabis. The increasing problematic use of alcohol may pose challenges to the safety and effectiveness of OAT. Development of comprehensive and tailored treatment strategies is needed for poly-substance users accessing OAT. BACKGROUND Promoting employment among unemployed adults with substance use disorder is a difficult challenge for which existing interventions have had limited effects. This study examined whether financial incentives could increase engagement in employment services for unemployed adults in treatment for opioid use disorder. METHODS The study was conducted from 2014 to 2019 in Baltimore, MD. After a 3-month abstinence initiation and training period, participants (N = 91) were randomly assigned to a Control group or an Incentive group and were invited to work with an employment specialist to seek employment in a community job for 12 months. Participants assigned to the Control group (n = 47) did not receive incentives for working with the employment specialist. Participants assigned to the Incentive group (n = 44) could earn financial incentives for working with the employment specialist, but had to provide opiate- and cocaine-negative urine samples to maximize pay. RESULTS Incentive participants attended the employment services and worked with the employment specialist on significantly more days than Control participants (41.8 % versus 1.1 % of days; OR = 40.42, 95 % CI = 32.46-48.38, p less then .001), and for significantly more
