Objective: This study assessed awareness, prevalence of trial, and frequency of Juul use among undergraduate students at three Mississippi universities. Methods: A random sample of students responded to web-based surveys assessing Juul awareness, trial, and use. Results: Most students were aware of Juul (69.5%) and recognized that a Juul pod provides as much nicotine as a pack of cigarettes (59.4%). A third of students had tried Juuls (37.1%); and three-quarters of trial users reported past 30-day use (76.1%). Among trial users, smokers and students in the Greek system were more likely to report past 30-day use than others, p<.05. Conclusion: Awareness and trial of Juul are high. Moreover, most trial users report daily or past week use, in contrast to many previous studies finding that most trial use is discontinued. Universities and policy makers need to be aware of Juul use among undergraduates, particularly those who are non-smokers.
Background: Recently, snus and electronic cigarettes have been introduced to the US market, while waterpipes have gained popularity. The purpose is to assess use of these products among youth and identify demographic, behavioral, and situational predictors of use. Methods: We administered the Mississippi Youth Tobacco Survey to high school students in the Fall of 2011. We applied a multi-stage sample design with public schools selected with a probability proportional to enrollment size. We randomly selected Classrooms within schools and all students in selected classes were eligible for participation. Data were collected by means of anonymous, self-administered questionnaires. Results: 90% of sampled schools and 79% of sampled students participated (overall response rate 71%). Ever use for hookah, snus, and e-cigarettes was 4.4%, 8.5%, and 5.9%, respectively; and current use was 1.6%, 3.7%, and 2.3%. Bivariate analyses demonstrated ever use of these products tended to be higher for males, whites, and those in higher grades. Significant behavioral and situational predictors of ever use included current cigarette smoking, being a susceptible nonsmoker, living in home that allowed smoking, past 7 day SHS exposure, at least one of closest four friends smokes, believing that smoking helps you look cool, and regarding secondhand smoke as not very harmful. Conclusions: Use of these products raises concerns about students being at risk for nicotine dependence or maintaining their dependence. Greater awareness of emerging tobacco product prevalence and high risk characteristics might inform efforts to determine public health policy and regulatory action.
Background: Mississippi is one of only seven states without any type of statewide law restricting smoking in private indoor workplaces, restaurants, or bars. The negative health effects associated with exposure to secondhand smoke have been well documented. Research is emerging related to the impact of local smoke-free policy on Mississippi's economic and population health. Methods: Systematic literature review of current research related to both the fiscal and physical effects of smoke-free policy. Results: A 2010 study revealed substantial reductions in heart attacks in two Mississippi cities following the implementation of smoke-free ordinances: a 22.7% reduction in heart attack admissions in Starkville (compared with a 14.8% reduction among non-residents) and a 13.4% reduction in heart attack admissions (compared with a 3.8% reduction among non-residents) were reported. Because of the small number of heart attack admissions, additional data are required to determine statistical significance. Peer reviewed studies have yet to show any negative impacts of smoke-free policy on the hospitality industry. Analysis of Mississippi Tourism and Economic Development (TED) tax revenues showed that in the 12 months after enacting municipal smoke-free ordinances, TED tax revenues were 10.3% higher in smoke-free communities, compared with TED tax revenues in communities without smoke-free ordinances. Discussion: While the body of literature specific to Mississippi is small, study results mirror what dozens of larger studies with statistical significance have shown in other populations. A state-wide smoke-free law could positively impact the economy and health status of Mississippians.
