Abstract

Crack addiction has become a severe public health problem in Brasil. Crack users present higher prevalence of psychiatric comorbidities, sexual transmitted infections and unemployment with higher probability of living or have lived in the streets, higher history of incarceration and engagement in illegal activities. For the last 20 years a treatment called Contingency Management (CM) have achieved the best results regarding reduction of drug use, promotion of abstinence, treatment participation and retention. The first CM study conducted in Brazil advocates for the efficacy on all of these outcomes, suggesting that CM can be effective in a Brazilian population of crack users. The objective of this study is to evaluate the effectiveness of CM for crack users living in the "Crackland" region. To achieve that goal regular staff from Helvetia and Cratod services will be capacitated in CM to latter on apply the CM protocol. This will be a crossover randomized clinical trial composed of a sample of 200 subjects with current diagnose for crack/cocaine dependence. After 12 weeks of intervention, participants in the control condition (standard treatment alone) will receive 12 weeks of the experimental treatment (standard treatment plus CM) and participants in the experimental condition will receive 12 weeks of the control procedure. Our hypothesis is that participants will have a better response to all studied outcomes when receiving the experimental procedure.
