Tested contingent access to methadone treatment as an incentive. 44 mixed opiate-cocaine abusers participated in a 90-day premaintenance probationary program. Ss were stabilized on 50 mg of methadone and assigned to 1 of 2 treatment groups. Contingent treatment patients were required to submit 2 consecutive weeks of cocaine-free urines during their 1st 7 wks of treatment to gain entry into 2 yrs of methadone maintenance (MM). For noncontingent patients, access to MM was based on a yoked control procedure. Ss not accepted to MM received a 6-wk detoxification. Ss in the contingent group were more likely to submit 2 consecutive weeks of cocaine-free urines than patients in the comparison group. Results demonstrate that contingent access to a longer duration of methadone treatment provides a practical and effective incentive for short-term cocaine abstinence.
