    Introduction: E-cigarette use remains a controversial topic in public health and medicine. Historically, cigarette smoking was identified as a gateway to marijuana use among adolescents. Recently, the prevalence of adolescent cigarette smoking has declined, but that of e-cigarette use continues to increase. As e-cigarettes eclipse cigarettes among adolescents, e-cigarette use may predispose adolescents to marijuana use. This study examines the relationship between e-cigarette use and marijuana use in a national sample of adolescents who have never smoked conventional cigarettes. Methods: A national sample of 8th and 10th grade never-smokers of conventional cigarettes (N=12,743) was obtained from 2014-2015 Monitoring the Future surveys. The dependent variable was past 30-day marijuana use (dichotomized Yes/No), and the independent variables were past 30-day e-cigarette use (dichotomized Yes/No), perceived availability of marijuana, peer marijuana use, parental monitoring, and religiosity. A multivariable logistic regression was conducted with marijuana use regressed on e-cigarette use, and other independent variables while controlling for covariates such as paid employment, risk-taking propensity, and sociodemographic variables. Additional regression analysis was conducted on e-cigarette users only. Results: Among adolescent never-smokers of conventional cigarettes, 5.2% and 5.6% had used marijuana and e-cigarettes, respectively, in the past 30 days. Among never-smokers who are current e-cigarette users, 24.2% had used marijuana at least once in the past 30-days, compared to 3.9% of non-e-cigarette users. Logistic regression analyses showed that e-cigarette users were three times more likely than non-users to be current marijuana users after adjusting for other variables. Perceived availability of marijuana and peer marijuana use increased the likelihood of marijuana use, while parental monitoring and religiosity were protective against marijuana use. Among e-cigarette users, the predictors of marijuana use were peer marijuana use and perceived availability of marijuana. Conclusion & Implications: A significant proportion of adolescents who have never smoked conventional cigarettes are current marijuana users. Among these adolescents, e-cigarette use is associated with a threefold increase in odds of marijuana use, suggesting a link between e-cigarette and marijuana use that is independent of conventional cigarette smoking. Among e-cigarette users, peer marijuana use and perceived availability of marijuana are particularly predictive of marijuana use and are potential foci for targeted interventions focused on reducing dual e-cigarette and marijuana use among adolescents

    The effect of cigarette price increase on the cigarette consumption in Taiwan: evidence from the National Health Interview Surveys on cigarette consumption

    BACKGROUND: This study uses cigarette price elasticity to evaluate the effect of a new excise tax increase on cigarette consumption and to investigate responses from various types of smokers. METHODS: Our sample consisted of current smokers between 17 and 69 years old interviewed during an annual face-to-face survey conducted by Taiwan National Health Research Institutes between 2000 to 2003. We used Ordinary Least Squares (OLS) procedure to estimate double logarithmic function of cigarette demand and cigarette price elasticity. RESULTS: In 2002, after Taiwan had enacted the new tax scheme, cigarette price elasticity in Taiwan was found to be -0.5274. The new tax scheme brought about an average annual 13.27 packs/person (10.5%) reduction in cigarette consumption. Using the cigarette price elasticity estimate from -0.309 in 2003, we calculated that if the Health and Welfare Tax were increased by another NT$ 3 per pack and cigarette producers shifted this increase to the consumers, cigarette consumption would be reduced by 2.47 packs/person (2.2%). The value of the estimated cigarette price elasticity is smaller than one, meaning that the tax will not only reduce cigarette consumption but it will also generate additional tax revenues. Male smokers who had no income or who smoked light cigarettes were found to be more responsive to changes in cigarette price. CONCLUSIONS: An additional tax added to the cost of cigarettes would bring about a reduction in cigarette consumption and increased tax revenues. It would also help reduce incidents smoking-related illnesses. The additional tax revenues generated by the tax increase could be used to offset the current financial deficiency of Taiwan's National Health Insurance program and provide better public services

    INTRODUCTION: The study aim was to examine impulsivity and other risk factors for e-cigarette use among women of reproductive age comparing current daily cigarette smokers to never cigarette smokers. Women of reproductive age are of special interest because of the additional risk that tobacco and nicotine use represents should they become pregnant. METHOD: Survey data were collected anonymously online using Amazon Mechanical Turk in 2014. Participants were 800 women ages 24-44years from the US. Half (n=400) reported current, daily smoking and half (n=400) reported smokingsociodemographics, tobacco/nicotine use, and impulsivity (i.e., delay discounting & Barratt Impulsiveness Scale). Predictors of smoking and e-cigarette use were examined using logistic regression. RESULTS: Daily cigarette smoking was associated with greater impulsivity, lower education, past illegal drug use, and White race/ethnicity. E-cigarette use in the overall sample was associated with being a cigarette smoker and greater education. E-cigarette use among current smokers was associated with increased nicotine dependence and quitting smoking; among never smokers it was associated with greater impulsivity and illegal drug use. E-cigarette use was associated with hookah use, and for never smokers only with use of cigars and other nicotine products. CONCLUSIONS: E-cigarette use among women of reproductive age varies by smoking status, with use among current smokers reflecting attempts to quit smoking whereas among non-smokers use may be a marker of a more impulsive repertoire that includes greater use of alternative tobacco products and illegal drugs

    This paper documents the rise of the Internet as a source of cigarette tax competition for states in the United States. Using data on cigarette tax rates, taxable cigarette sales and individual smoking rates by state from 1980 to 2005 merged with data on Internet penetration, the paper documents a substantial increase in the sensitivity of taxable cigarette sales correlated with the rise of Internet usage within states. The estimates imply that the increased sensitivity from cigarette smuggling over the Internet has lessened the revenue generating potential of recent cigarette tax increases substantially. Given the continuing growth of the Internet and of Internet cigarette merchants, the results imply serious problems for state revenue authorities.cigarette tax, cigarette sales, cigarette smuggling

    Cigarette consumption in The Netherlands 1970-1995 - Does tax policy encourage the use of hand-rolling tobacco?

    Get PDF
    Background: Tax rises to reduce cigarette consumption are a major feature of European tobacco control policies. In many countries, hand-rolling tobacco is much cheaper than manufactured cigarettes. We Investigated whether changes in price differentials between manufactured and hand-rolled cigarettes influenced cigarette consumption in The Netherlands. Method: We developed regression models to explain changes in the consumption of the two cigarette types. Price elasticities, the percentage changes in consumption for a 1% change in price, are calculated from Netherlands data for 1970-1980 and 1985-1995. Results: The ratio of manufactured to hand-rolled cigarette prices changed little during 1970-1980 but varied subsequently. On multivariate analysis, manufactured cigarette consumption in 1970-1980 decreased as its price rose (elasticity = -0.74). In 1985-1995, manufactured cigarette consumption fell with increases in both its own price (elasticity = -0.54) and in the price differential between manufactured and hand-rolled cigarettes (elasticity = -0.60). During 1985-1995, roll-your-own consumption fell as the price ratio of manufactured to hand rolled cigarettes fell (elasticity = +1.0). Conclusion: When the price rise for hand-rolling tobacco is greater than the price rise for manufactured cigarettes, the fall in manufactured cigarette consumption is accompanied by a fall in roll-your-own use. Cigarette smokers are deterred from switching to hand rolled cigarettes instead of stopping smoking. This increases the health benefits of raising taxes on manufactured cigarettes, discourages the use of even more harmful forms of tobacco and may reduce inequalities in health
