Alcohol - assessed by self-report of use (TLFB,DD,DDD,PDA, PHDD), biochemical markers (GGT, CDT), OCDS

Cocaine - assessed by self-report of use (CTFB, substance use inventory, QFI),urine assay for benzoylecgonine, and CCQ-NOW

Secondary Outcome Measures
NameTimeMethod
a. Cocaine free weeks; b. Topiramate, compared with placebo, will be associated with an improvement in psychosocial functioning as exemplified by improved general well-being, social functioning, and quality of life.According to Preston Rules from weeks 1 to 12

1. Cocaine free weeks is assessed by a combination of self-report of use and urine assays;
