Brief Summary
The purpose of this study is to develop a model for long-term maintenance of behavior change by examining the effects of extending the duration of contingency management (CM) for drug abuse on long-term abstinence outcomes. The primary hypothesis is that the Extended (36 week) CM group will have better long-term outcomes as exhibited by greater rates of abstinence at each follow-up assessment as compared to the Standard (12 week) CM group.
