Abuse Liability and Appeal of Oral Nicotine Products

There has been a recent proliferation of novel oral nicotine products (ONPs) brought to market, including new nicotine gums and pouches. Unlike electronic cigarettes (ECs) ONPs have no impending regulatory barriers with regard to flavoring or nicotine dose, and manufacturers have capitalized on this by introducing an extensive slate of characterizing flavors and nicotine concentrations. Both sales trajectory and the surge in marketing suggest ONP use is likely to increase in the coming years. Work by the investigators and others indicates that interest in these products is high among current EC users, and among specific demographic groups including those who identify as sexual and gender minority (SGM). ONP use is discrete and so can function as a secondary source of nicotine, encouraging dual use patterns and more severe nicotine dependence. Depending on the use patterns of ONPs that emerge, regulation of ONPs may serve the public health interest. However, very little is known about factors relevant to the actual appeal and abuse liability of these products. The investigators propose to address this important gap by assessing the appeal and abuse liability of gum and pouch ONPs as a function of flavor (mint vs fruit) and nicotine concentration (2mg vs. 4mg). Flavor and nicotine strength, along with product type, are regulatable attributes, and so it is essential to understand their impact on appeal and abuse liability. Evidence from EC use suggests a potential interaction be…
