Incentive-based Smoking Cessation for Methadone Patients

Direct comparison of Contingent versus Noncontingent incentives in promoting abstinence from smoking among opioid-treatment patients. The biochemical measures of breath carbon monoxide levels and urinary cotinine are used to confirm smoking status. Participants receive voucher-based incentives either contingent upon demonstrating abstinence from recent smoking (Contingent condition) or independent of smoking status (Noncontingent control condition).
