INTRODUCTION

In the US, overall electronic nicotine delivery system (ENDS) sales have climbed steadily over the years and reached a record-high 22 million units in March 20211. Although the evidence on ENDS’ short- and long-term health effects is not definitive2,3, the products are most frequently used by current (past 30-day) smokers4,5. Compared to combustible cigarettes, users perceive ENDS as a healthier alternative and useful quitting aid6. Major ENDS manufacturers’ websites are one of the dominant channels to market claims of smoking cessation and health benefits7,8, but evidence of such claims on the websites of brick-and-mortar vape shops is scarce.

Increasing ENDS sales have been accompanied by the rise of brick-and-mortar vape shops8,9. Accounting for 30% of all ENDS sales10, more than 10000 vape shops have opened in the US during the past decade11,12. Unlike major ENDS manufactures, vape shops offer consumers a more interactive experience, including face-to-face marketing to promote the products13, and personal interaction with employees who often also use ENDS14, and provide their perceptions of the products. Thus, it is important to identify the types of ENDS marketing claims consumers are exposed to on the websites of brick-and-mortar vape shops.

To date, most studies on website ENDS marketing have focused on major retailers, manufacturers, and major commercial tobacco companies15,16. With the ENDS and vape market rapidly growing and evolving, monitoring and surveillance of the types of marketing claims disseminated by vape shop retailers can inform tobacco control policy and regulations. Given the knowledge gap, the present study sought to examine ENDS marketing claims on the websites of brick-and-mortar vape shops in the Los Angeles metropolitan area – the second-largest urban region area in the US17.

METHODS

The data used in this study are publicly available via brick-and-mortar vape shop websites. A total of 104 brick-and-mortar vape shops were identified in the Greater Los Angeles Area using Yelp18. A total of 37 of the 104 brick-and-mortar vape shops were found to have active websites at the time of data collection (25 March – 20 June 2020).

Coding categories included: Age Verification (i.e. the presence or absence of a popup window to verify age for access to the website) and Nicotine Warning Label (i.e. the presence or absence of nicotine addictiveness warning statement on product packages or advertisements on the website). Similar to previous research19,20, ENDS Marketing Claims were coded as the presence or absence of: 1) a direct claim of ENDS as a quitting aid; 2) a disclaimer that ENDS are not approved as smoking cessation devices (given that ENDS products are not FDA-approved for smoking cessation21,we sought to further inform tobacco regulatory policy); 3) a direct claim of ENDS as healthier/safer than combustible cigarettes; and 4) direct claims regarding social benefits, including that ENDS are cheaper, can be used in more places, are cleaner or less messy/smelly, and are more socially accepted than combustible cigarettes.

Four coders (MP, NM, SW, NT) independently double coded all categories and recorded qualitative texts for each ENDS marketing claim to ensure reliability. Discrepancies were resolved via weekly discussion. The estimated intercoder reliability coefficient (Cohen’s kappa) was 0.93, with almost complete agreement between the coders. The University of Southern California Institutional Review Board approved the research protocol.

Data analysis

Descriptive and summary statistics were conducted using SAS software, Version 9.3 (SAS Institute, Cary NC). We report the frequency of each coding category.

RESULTS

Website characteristics

More than half (59.5%; n=22) of the total (n=37) websites had an age restriction, requiring the user to click on a box to state that they were aged ≥21 years to view the site. None required proof or outside verification of age. Nearly seventy percent (67.6%; n=25) of sites had a nicotine warning label on product packages or advertisements. More than half (56.8%; n=21) of sites had external links to social media sites (i.e. Instagram, Facebook).

Marketing claims

As shown in Table 1, smoking cessation-related benefits were claimed most frequently (43.2%; n=16), such as stating: ‘vaping allows you to quit smoking – smoking is as much about a physical habit as it is about the dependence on nicotine’. Websites also frequently (29.7%; n=11) presented claims of ENDS as healthier/safer (e.g. ‘This vape shop was built off the idea of harm reduction’) than smoking cigarettes. Nine (24.3%) websites presented disclaimers that ENDS are not approved as smoking cessation devices, such as stating: ‘electronic cigarettes and e-liquids are not smoking cessation products per FDA and are not intended to prevent or cure any disease or condition’. Six websites (16.2%) claimed that ENDS are cheaper (e.g. ‘... more cost-effective in the long run than cigarettes’) and cleaner to use than combustible cigarettes (e.g. ‘... all in all, electronic cigarettes are much cleaner’); 4 (10.8%) claimed that ENDS can increase social status (e.g. ‘Smoking affected our mood, our wallets, our family and our friends. We wanted a way out’); and 1 claimed ability to use ENDS in more places compared to smoking cigarettes.

ClaimDefinitionText example
Quitting aid/cessation relatedA direct claim(s) of ENDS as a quitting aid.‘Vaping allows you to quit smoking – smoking is as much about a physical habit as it is about the dependency on nicotine.’
Not a quitting aid/cessation relatedA disclaimer(s) that ENDS are not approved by the U.S. Food and Drug Administration as smoking cessation devices.‘Electronic cigarettes and e-liquids are not smoking cessation products per FDA and are not intended to prevent or cure any disease or condition.’
Healthier/safer than cigarettesA direct claim(s) of ENDS as healthier/safer than combustible cigarettes.‘This vape shop was built off the idea of harm reduction.’
‘Vaping requires no combustion and is void of any tar or carcinogens. There are no known harmful side effects to vaping e-liquid.’
Cheaper than cigarettesA direct claim(s) of ENDS as cheaper than combustible cigarettes or will save the user money.‘Beyond the daily savings, a smoker's health insurance costs will decrease after switching to electronic cigarettes, because 'vaping' is not smoking, which is the leading cause of preventable death.’
Ability to use in more placesA direct claim(s) that ENDS can be used in more places than cigarettes.‘Vaping can legally be done anywhere smoking cigarettes can be done, with the addition of some indoor establishments.’
Cleaner than cigarettesA direct claim(s) that ENDS are cleaner or less messy/smelly than cigarettes.‘Vaping electronic cigarettes eliminates the foul odor of tobacco cigarettes from your life. You will not stink of cigarette smoke and your clothes, car, and furniture will not have that lingering odor ... All in all, electronic cigarettes are much cleaner.’
Socially acceptedA direct claim(s) that there is no social stigma associated with using ENDS compared to smoking cigarettes.‘Smoking affected our mood, our wallets, our family and our friends. We wanted a way out.’

DISCUSSION

The findings of the present study showed that brick-and-mortar vape shops in the Greater Los Angeles Area are marketing ENDS on their websites as healthier alternatives to smoking cigarettes. According to the results of this study, websites most frequently claim smoking cessation-related benefits, followed by claims of ENDS as healthier/safer than cigarettes, and disclaimers that ENDS are not approved as smoking cessation devices. These findings suggest that ENDS marketing claims on the websites of brick-and-mortar vape shops in the Greater Los Angeles Area may particularly appeal to cigarette smokers, and consumers are likely to encounter misleading health claims in ENDS marketing, and mixed messages about whether ENDS are smoking cessation devices.

The findings of this study are in line with previous ENDS marketing analysis research19,22 in terms of claims that ENDS are effective for smoking cessation, healthier/safer than cigarettes, and have more social benefits (i.e. cheaper and cleaner to use than cigarettes, increased social status). Additionally, similar to the historical marketing tactics of the tobacco industry’s social acceptability advertisements targeting cigarette smokers23, the claims of ENDS as more socially beneficial than cigarettes, may particularly appeal to smokers.

More than half of websites had an age restriction requiring the user to click on a box to state that they were aged ≥21 years to view the site. However, none of the websites required proof or outside verification of age. These findings are consistent with previous research19, suggesting that youth have potential for access to ENDS and exposure to online ENDS marketing claims.

Limitations

This study has some limitations. Our findings may not be generalizable beyond the websites analyzed. Our analysis was limited to the websites of brick-and-mortar vape shops in the Greater Los Angeles Area. We excluded the websites of other brick-and-mortar vape shops, and retail websites that sell a specific ENDS brand. We also excluded Web-based channels that are used to market tobacco products, including social media. Further, data reflect ENDS marketing claims at specific moments in time.

CONCLUSIONS

This study presents an analysis of the websites of vape shop retailers in the Greater Los Angeles Area to describe how they market ENDS. We found that utility for smoking cessation was claimed most frequently, followed by the claims of healthier alternatives to smoking cigarettes, and disclaimers that ENDS are not approved as smoking cessation devices. This new knowledge has the potential for encouraging tobacco control regulators to prohibit ENDS marketing claims that are misleading and unsupported by scientific evidence. Findings also suggest that action is needed to better enforce age restriction on access to vape shop websites.
