Study Summary

Tobacco use kills more than 500,000 people in the United States each year. Although the use of cigarettes has declined, the use of other tobacco products has remained steady. Waterpipe smoking is a common form of tobacco smoking after cigarettes in the U.S. In fact, in 2007 the American Lung Association issued a policy alert to warn consumers about this first new tobacco trend of the 21st century (American Lung Association, 2007). Few studies have been conducted on waterpipe smoking to investigate its harmful effects. Furthermore, no known studies have evaluated treatments for smoking cessation in waterpipe smokers. This study aims to test the role of contingency management (CM) in promoting abstinence from waterpipe smoking for 5 weeks verified by salivary cotinine and to characterize self-reported nicotine withdrawal symptoms. Based on the alarming growth rate over a short period of time in waterpipe tobacco smoking, there is a critical need for clinical research to investigate treatment modalities targeting smoking cessation for waterpipe smokers. Given the evidence for the role of CM in promoting abstinence from many types of drug use, investigation of the utility of CM for waterpipe smoking cessation is important and timely. Although Nicotine Replacement Therapy is the mainstay treatment for treating nicotine dependence delivered through cigarettes, the intermittent use patterns that characterize waterpipe smoking suggest that CM may be more effective in promoting waterpipe smoking cessation. The evidence based knowledge generated in this study may assist in the translation of the treatment program into public health practice.

Primary Outcome

Quitting waterpipe smoking will be assessed using saliva cotinine test twice a week for five weeks. Also, participants will be asked at each visit if they have smoked waterpipe during the past days between visits.
