IRB Committee: This study has been reviewed and approved by the University Of Oklahoma Health Sciences Center (OUHSC) Institutional Review Board
According to the Centers for Disease Control and Prevention (CDC), smoking can lead to tobacco/nicotine dependence, resulting in adverse health outcomes. The CDC states that smokers can and do quit smoking for good. Statistics have shown that smoking has declined from 20.9% (21 out of 100 adults) in 2005 to 14% (14 out of 100 adults) in 2019.
Quitting smoking reduces the risk of developing many health problems. Researchers are exploring potential treatment strategies and resources for quitting smoking. This particular research study seeks to compare a standard smoking cessation treatment to a treatment that compensates people when they are able to quit. Researchers also want to further understand what leads to quitting smoking or going back to smoking.
The Prevail II research study or the Tobacco Treatment Research Program is looking for interested participants who are currently smoking and are willing to quit smoking. Compensation will be available to eligible individuals for participating in this study upon completion of all the necessary study requirements.
