E-cigarette Advertising Expenditures in the U.S., 2011–2012

Annice E. Kim; Kristin Y. Arnold; Olga Makarenko

BACKGROUND Electronic cigarettes (e-cigarettes) are growing in popularity, but little is known about the extent to which these products are advertised to consumers. PURPOSE To estimate expenditures for e-cigarette advertising in magazines, TV, the Internet, newspapers, and radio in the U.S. from 2011 to 2012. METHODS E-cigarette advertising data were obtained from leading media intelligence companies, Kantar Media and Nielsen. Estimated e-cigarette advertising expenditures were summarized across media channels for 2011 and 2012. Additional information on brands advertised and market-level buys (i.e., local versus national) also was examined. RESULTS Overall, e-cigarette advertising expenditures across media channels tripled from

18.3 million in 2012. Expenditures were highest in magazines and TV and lowest in newspapers and on the Internet. More than 80 unique brands were advertised, but blu eCigs dominated ad spending, comprising 76.7% of all e-cigarette advertising expenditures in 2012. National markets were increasingly targeted from 54.9% of ad buys in 2011 to 87.0% of ad buys in 2012. CONCLUSIONS E-cigarette advertising expenditures are increasing, with a greater focus on national markets and TV ads, which will likely increase consumer awareness and use of e-cigarettes in the future. Federal-level efforts are needed to mandate that e-cigarette companies report their advertising expenditures. Future studies should examine how e-cigarette advertising expenditures and message content influence consumer awareness of, interest in, and use of e-cigarettes.

‘Vape shops’ and ‘E-Cigarette lounges’ open across the USA to promote ENDS

Youn Ok Lee; Annice E. Kim

BACKGROUND: Noncigarette tobacco products are increasingly popular among youth, especially cigarette smokers. Understanding multiple tobacco product use is necessary to assess the effects of tobacco products on population health. This study examines multiple tobacco product use and associated risk factors among US youth. METHODS: Estimates of current use were calculated for cigarettes, cigars, smokeless tobacco, hookah, e-cigarettes, pipes, bidis, kreteks, snus, and dissolvable tobacco by using data from the 2012 National Youth Tobacco Survey (n = 24 658), a nationally representative sample of US middle and high school students. Associations between use patterns and demographic characteristics were examined by using multinomial logistic regression. RESULTS: Among youth, 14.7% currently use 1 or more tobacco products. Of these, 2.8% use cigarettes exclusively, and 4% use 1 noncigarette product exclusively; 2.7% use cigarettes with another product (dual use), and 4.3% use 3 or more products (polytobacco use). Twice as many youth use e-cigarettes alone than dual use with cigarettes. Among smokers, polytobacco use was significantly associated with male gender (adjusted relative risk ratio [aRRR] = 3.71), by using flavored products (aRRR = 6.09), nicotine dependence (aRRR = 1.91), tobacco marketing receptivity (aRRR = 2.52), and perceived prevalence of peer use of tobacco products (aRRR = 3.61, 5.73). CONCLUSIONS: More than twice as many youth in the United States currently use 2 or more tobacco products than cigarettes alone. Continued monitoring of tobacco use patterns is warranted, especially for e-cigarettes. Youth rates of multiple product use involving combustible products underscore needs for research assessing potential harms associated with these patterns.

Objective The aim of the present work was to examine adult smokers’ awareness of and receptivity to an electronic nicotine delivery system (ENDS) television advert, and whether viewing the advert influenced urge to smoke and intention to try ENDS. Methods A television advert for ENDS brand blu eCigs was shown to an online convenience sample of 519 Florida adult smokers. We measured current smokers’ awareness of and receptivity to the advert, and whether seeing the advert influenced their thoughts about smoking or quitting, urge to smoke and intention to try ENDS. Results were stratified by prior ENDS use. Results Approximately 62.3% of current smokers were aware of the advert. Smokers found the advert informative (73.8%), attention grabbing (67.5%) and innovative (64.5%), with prior ENDS users rating the advert more favourably than non-users. Seeing the advert elicited an urge to smoke (mean 42.1, SD=1.9) and thoughts about smoking cigarettes (75.8%) as well as quitting (74.6%). Prior END users were significantly more likely than non-users to report thinking about smoking cigarettes after seeing the advert (P<0.05). Most smokers said ENDS were ‘made for people like them’ (88.6%) and they would try ENDS in the future (66.0%). Conclusions Smokers are receptive to ENDS television adverts and report intention to try ENDS after viewing the advert. Future studies should monitor ENDS advertising and examine how exposure to ENDS adverts influences smokers’ use of ENDS, dual use with cigarettes and cessation behaviour.

4 billion globally by the end of 2013.3 From 2010 to 2011, awareness of ENDS among US adults increased from 40.9% to 57.9% and ever use increased from 3.3% to 6.2%.4 ENDS organisations have formed an industry that has begun advocating for its interests by promoting ENDS products and favourable policies for ENDS manufacturers and retailers.5 ENDS were initially promoted and sold online, but have quickly expanded to traditional brick and mortar retail outlets, like grocery stores and gas stations. Independent retail specialty shops that exclusively sell ENDS products, or ‘vape shops’, are opening around the USA and abroad,3 with over 3500 such shops estimated in the USA6 (figure 1). Vape shops sell ENDS products found in traditional retail stores (eg, starter kits, cartridges and disposable ENDS) but can offer a substantially …

Background Marketing and use of electronic cigarettes (e-cigarettes) and other electronic nicotine delivery devices have increased exponentially in recent years fueled, in part, by marketing and word-of-mouth communications via social media platforms, such as Twitter. Objective This study examines Twitter posts about e-cigarettes between 2008 and 2013 to gain insights into (1) marketing trends for selling and promoting e-cigarettes and (2) locations where people use e-cigarettes. Methods We used keywords to gather tweets about e-cigarettes between July 1, 2008 and February 28, 2013. A randomly selected subset of tweets was manually coded as advertising (eg, marketing, advertising, sales, promotion) or nonadvertising (eg, individual users, consumers), and classification algorithms were trained to code the remaining data into these 2 categories. A combination of manual coding and natural language processing methods was used to indicate locations where people used e-cigarettes. Additional metadata were used to generate insights about users who tweeted most frequently about e-cigarettes. Results We identified approximately 1.7 million tweets about e-cigarettes between 2008 and 2013, with the majority of these tweets being advertising (93.43%, 1,559,508/1,669,123). Tweets about e-cigarettes increased more than tenfold between 2009 and 2010, suggesting a rapid increase in the popularity of e-cigarettes and marketing efforts. The Twitter handles tweeting most frequently about e-cigarettes were a mixture of e-cigarette brands, affiliate marketers, and resellers of e-cigarette products. Of the 471 e-cigarette tweets mentioning a specific place, most mentioned e-cigarette use in class (39.1%, 184/471) followed by home/room/bed (12.5%, 59/471), school (12.1%, 57/471), in public (8.7%, 41/471), the bathroom (5.7%, 27/471), and at work (4.5%, 21/471). Conclusions Twitter is being used to promote e-cigarettes by different types of entities and the online marketplace is more diverse than offline product offerings and advertising strategies. E-cigarettes are also being used in public places, such as schools, underscoring the need for education and enforcement of policies banning e-cigarette use in public places. Twitter data can provide new insights on e-cigarettes to help inform future research, regulations, surveillance, and enforcement efforts.

Background The promotion of evidence-based cessation services through social media sites may increase their utilization by smokers. Data on social media adoption and use within tobacco control programs (TCPs) have not been reported. Objective This study examines TCP use of and activity levels on social media, the reach of TCP sites, and the level of engagement with the content on sites. Methods A cross-sectional descriptive study of state TCP social media sites and their content was conducted. Results In 2013, 60% (30/50) of TCPs were using social media. Approximately one-quarter (26%, 13/50) of all TCPs used 3 or more social media sites, 24% (12/50) used 2, and 10% (5/50) used 1 site. Overall, 60% (30/50) had a Facebook page, 36% (18/50) had a Twitter page, and 40% (20/50) had a YouTube channel. The reach of social media was different across each site and varied widely by state. Among TCPs with a Facebook page, 73% (22/30) had less than 100 likes per 100,000 adults in the state, and 13% (4/30) had more than 400 likes per 100,000 adults. Among TCPs with a Twitter page, 61% (11/18) had less than 10 followers per 100,000 adults, and just 1 state had more than 100 followers per 100,000 adults. Seven states (23%, 7/30) updated their social media sites daily. The most frequent social media activities focused on the dissemination of information rather than interaction with site users. Social media resources from a national cessation media campaign were promoted infrequently. Conclusions The current reach of state TCP social media sites is low and most TCPs are not promoting existing cessation services or capitalizing on social media’s interactive potential. TCPs should create an online environment that increases participation and 2-way communication with smokers to promote free cessation services.
