We compared data obtained from only (14 male) exposed both conditions. Participants attended more sessions retained for longer period during CMC than UCC (p < .01 both). The proportion negative samples submitted, mean longest duration abstinence, odds being abstinent significantly higher when (p < .05). This study provides further that effective promoting abstinence retention response.
