Many smokers have become “dual users” of both cigarettes and smokeless tobacco (SLT). The goal of this project is to understand how smokers’ health risks are affected as a result of dual use by characterizing their natural patterns of tobacco use. Specific aims are: (1) to determine whether cigarette smokers alter their smoking behavior on days when they also use SLT; and (2) to profile the patterns of SLT use among cigarette smokers within and across days. Researchers will study 120 adult smokers who also use SLT aged 18-55 for two weeks to determine their patterns of dual use of cigarettes and SLT. Participants will use electronic diaries to record various behaviors, contextual factors, and subjective experiences; they will also provide saliva samples so that cotinine levels can be analyzed to determine daily levels of nicotine exposure. Researchers will compare cigarette use on single (cigarettes only) versus dual use days, and will evaluate dual use as a function of various factors including indoor vs. outdoor activities, other drug use (i.e., caffeine, alcohol), type of SLT product used, mood, SLT use motivations and beliefs, and nicotine/tobacco craving level. Study results will shed light on whether cigarette smokers’ use of SLT is consistent with product supplementation or replacement, and thus how SLT use influences exposure to nicotine.
