Use of Emerging Tobacco Products in the United States

This paper provides the first nationally representative estimates for use of four emerging products. Addressing the issue of land-line substitution with cell phones, we used a mixed-mode survey to obtain two representative samples of US adults. Of 3,240 eligible respondents contacted, 74% completed surveys. In the weighted analysis, 13.6% have tried at least one emerging tobacco product; 5.1% snus; 8.8% waterpipe; 0.6% dissolvable tobacco products; 1.8% electronic nicotine delivery systems (ENDS) products. Daily smokers (25.1%) and nondaily smokers (34.9%) were the most likely to have tried at least one of these products, compared to former smokers (17.2%) and never smokers (7.7%), P < .001. 18.2% of young adults 18-24 and 12.8% of those > 24 have tried one of these products, P < .01. In multivariable analysis, current daily (5.5, 4.3-7.6), nondaily (6.1, 4.0-9.3), and former smoking status (2.7, 2.1-3.6) remained significant, as did young adults (2.2, 1.6-3.0); males (3.5, 2.8-4.5); higher educational attainment; some college (2.7, 1.7-4.2); college degree (2.0, 1.3-3.3). Use of these products raises concerns about nonsmokers being at risk for nicotine dependence and current smokers maintaining their dependence. Greater awareness of emerging tobacco product prevalence and the high risk demographic user groups might inform efforts to determine appropriate public health policy and regulatory action.
