Title: A Sequenced Behavioral and Medication Intervention for Cocaine Dependence
Brief Summary: This study will investigate a treatment strategy in which a computer-assisted behavioral intervention will be used to help individuals stop their use of cocaine. A medication will be combined with the behavioral treatment among those individuals who do not respond to the behavioral intervention alone. The primary hypothesis of the study is that among cocaine dependent individuals who fail to respond to an initial trial of behavioral therapy, a greater proportion of individuals will benefit from the combined treatment (behavior therapy plus medication) compared to individuals in the comparison group.
