Title: Varenicline Augmentation of Patch Outcomes in Heavy Drinkers' Smoking Cessation
Brief Summary: The purpose of this study is to learn if the combination of a study drug and patch is more effective in helping heavy drinkers stop smoking than just the patch alone The study drug, varenicline, has been approved by the Food and Drug Administration (FDA) to help people stop smoking, but it is not known if the addition of varenicline to standard smoking cessation treatment with nicotine patches will help people stop smoking who are regular, frequent drinkers. This study is being done because cigarette smoking is the number one preventable cause of death and disease in the United States.
