Examining market trends in the United States smokeless tobacco use: 2005–2011

Background While cigarette consumption in the USA continues to decline, promotion for and consumption of smokeless tobacco (SLT) is growing. However, little research has explored what product features are driving SLT growth, despite awareness that product-level factors may be important in SLT use. This study analyses national sales data to better understand the impact of product features on SLT sales. Methods Data on sales of SLT in US convenience stores from 2005 to 2011 were obtained from Nielsen Research Company. Each listed product was coded for attributes such as type, brand, flavouring and form to calculate their respective total sales, market share and contribution to overall SLT growth. Results Sales of moist snuff products (including snus) increased by 65.6% between 2005 and 2011. Sales of pouched and flavoured forms of moist snuff increased by 333.8% and 72.1%, respectively, and contributed to 28% and 59.4% of the total growth in the moist snuff category, respectively. Value/discount brands accounted for 42% of moist snuff sales in 2011 among the top 10 selling brands, largely driven by Grizzly. After 2 years on the national market, Camel Snus was also one of the top 10 selling moist snuff brands. Conclusions Sales of moist snuff, both overall and for particular styles, are increasing. Growing pouch use may be attributed to new SLT users, which may include cigarette smokers using them as starter SLT products. Increased sales of flavoured and discounted snuff raise concerns about use and appeal to youth. Continued surveillance of SLT sales trends is warranted.

Hookah use among New Jersey youth: associations and changes over time.

OBJECTIVES To assess hookah use among youth for prevalence, associations, and changes over time. METHODS Data from the 2008 and 2010 New Jersey Youth Tobacco Survey were analyzed to examine hookah smoking by gender, race/ethnicity, and grade level. RESULTS Prevalence of hookah use increased significantly among black and Hispanic students. Frequency of use was generally occasional. In multivariate models, Asian race; Hispanic ethnicity; and concurrent use of cigarettes, cigars, and bidis predicted current hookah smoking. CONCLUSIONS Prevalence of hookah use is rising among New Jerseys youth, particularly among minority populations, representing a growing public health concern.

Social norms and its correlates as a pathway to smoking among young Latino adults

Socially and culturally embedded norms regarding smoking may be one pathway by which individuals adopt smoking behaviors. However, few studies have examined if social norms operate in young adults, a population at high risk of becoming regular smokers. There is also little research examining correlates of social norms in populations with a large immigrant segment, where social norms are likely to differ from the receiving country and could contribute to a better understanding of previously reported acculturation-health associations. Using data from a nationally representative sample of young adults in the United States reached via a novel cell-phone sampling design, we explored the relationships between acculturation proxies (nativity, language spoken and generational status), socioeconomic position (SEP), smoking social norms and current smoking status among Latinos 18-34 years of age (n = 873). Specifically, we examined if a measure of injunctive norms assessed by asking participants about the acceptability of smoking among Latino co-ethnic peers was associated with acculturation proxies and SEP. Results showed a strong gradient in smoking social norms by acculturation proxies, with significantly less acceptance of smoking reported among the foreign-born and increasing acceptance among those speaking only/mostly English at home and third-generation individuals. No consistent and significant pattern in smoking social norms was observed by education, income or employment status, possibly due to the age of the study population. Lastly, those who reported that their Latino peers do not find smoking acceptable were significantly less likely to be current smokers compared to those who said their Latino peers were ambivalent about smoking (do not care either way) in crude models, and in models that adjusted for age, sex, generational status, language spoken, and SEP. This study provides new evidence regarding the role of social norms in shaping smoking behaviors among Latino young adults and suggests distinct influences of acculturation proxies and socioeconomic condition on smoking social norms in this population.

The Impact of Smokeless Tobacco Risk Information on Smokers’ Risk Perceptions and Use Intentions: A News Media Experiment

ABSTRACT Little research exists on the impact of risk information comparing smokeless tobacco (SLT) use, particularly snus, to cigarette smoking. This study explored this topic using a communication channel where smokers may be exposed to such information—the news media. We randomly assigned 1008 current smokers to read one of three constructed news stories or to a control group (no article). The “favorable” story framed snus as a “safer” smoking alternative while the “cautious” story described snus risks. The “mixed” version described potential risks and harm-reduction benefits. Participants completed a post-article survey with snus risk and harm perception and use intention measures. Article condition was significantly associated with perceived harm of daily snus use relative to smoking (1 = a lot less harmful – 5 = a lot more harmful; p < .0001), and mean ratings of snus harm in the favorable (2.46) and mixed conditions (2.66) were significantly lower than those of the cautious (2.96) and control conditions (2.98). Mean interest in trying snus in the next 6 months was low, but significantly higher for those in the favorable (1.55) and mixed conditions (1.32) versus those in the cautious (1.17) and control conditions (1.16)(1 = not at all – 5 = extremely interested, p < .0001). There were no significant differences by group in terms of the story’s perceived interestingness, importance, or relevance. Exposure to reduced-risk news messages about SLT and snus relative to cigarettes may impact smokers’ SLT harm perceptions and use intentions. Tobacco control professionals and FDA officials should consider the potential impact of the news media when communicating about tobacco risks.

The Importance of Contextual and Temporal Accuracy When Studying Novel Tobacco Products

The study by Dutra and Glantz examined cigarette and electronic cigarette (e-cigarette) trends among US middle and high school students via an interrupted time-series analysis of the National Youth Tobacco Survey (NYTS). The authors concluded that the rate of decline in smoking prevalence did not change after the introduction of e-cigarettes into the US market. We vehemently disagree with their choice to test change in slope at 2009 and note additional problems with their methodology and subsequent interpretations. An interrupted time-series study design, “requires a clear differentiation of the preintervention period and the postintervention period…. This does not necessarily require the intervention to be … E-mail: michelle.manderski{at}rutgers.edu

Relighting behaviour among cigarette smokers seeking treatment: implications for tobacco treatment and policy

During the recent economic downturn, trends towards fewer cigarettes smoked per day have emerged along with the practice of extinguishing and relighting cigarettes. Few studies have characterised factors related to relighting cigarettes and none have explored this behaviour in those seeking tobacco treatment. This study describes treatment‐seeking patients who relight cigarettes and examines implications on tobacco policy and treatment.
