Intention to quit tobacco use among clients in substance use disorder treatment settings.

The purpose of this study was to investigate the influence of age, gender, tobacco-related knowledge, treatment modality, and changes in smoking patterns on intention to quit tobacco use among individuals participating in substance use disorder (SUD) treatment in Ohio. Of the 791 SUD program attendees, 91.7% currently used tobacco, with cigarette smoking being the most prevalent form of use. Among tobacco users, 67% reported intention to quit tobacco use. Four of the five hypothesized predictor variables had a significant relationship with intention to quit tobacco: gender, age, treatment modality, and smoking pattern, with age and gender demonstrating the strongest relationships to intention to quit smoking.
