Smokers’ Understandings of Addiction to Nicotine and Tobacco: A Systematic Review and Interpretive Synthesis of Quantitative and Qualitative Research

Despite the centrality of addiction in academic accounts of smoking, there is little research on smokers' beliefs about addiction to smoking, and the role of nicotine in tobacco dependence. Smokers' perspectives on nicotine's role in addiction are important given the increasing prevalence of nontobacco nicotine products such as e-cigarettes. We conducted a systematic review of studies investigating smokers' understandings and lay beliefs about addiction to smoking and nicotine.
