The vape shop industry is a rapidly growing market sector with a constantly changing product landscape. The rapid evolution of nicotine delivery systems, most notably the emergence of salt nicotine e-juice and pod mod devices, have resulted in a sudden shift in the product market, suggesting new implications for the health professions in addressing electronic cigarette use.

Vape shops specialize in the sales of e-cigarettes and other vaping products. In recent studies, young adults who use e-cigarettes have tended to identify with at-risk peer crowds. This is the first study to examine vape shop customers' clientele. Composed primarily of young adults and persons in early middle adulthood, we speculated that a relatively high prevalence of those who appeared to bystanders as radical/extreme (at-risk) customers would be identified as such at these shops. We recruited vape shops throughout Southern California (N = 44 shops), and trained teams of data collectors visited each of the consented vape shops, making note of 451 customers' appearance, including features such as manner of dress, presence of tattoos, and hairstyles. Customers were then coded as either belonging to a conventional, progressive, or radical/extreme crowd based on outward appearance. Of the customers observed, 223 (49%) were rated as appearing to be in the conventional crowd; 169 (38%) were rated as appearing to be in the progressive crowd, and only 59 (13%) were rated as appearing to be in the radical/extreme crowd. The conventional crowd tended to appear older. Clientele may reflect that more conventional young and early middle age adults are tempted to visit vape shops due to perceptions of greater acceptability or safety of e-cigarettes. E-cigarette mass media campaigns aimed at protecting potential vape shop customers from harm may need to depict more conservative-looking characters.

Introduction

This study examined smoking cessation advice offered by vape shop employees, as well as their perceived awareness of vaping research.

Aims and methods

This cross-sectional study was conducted in 121 vape shops in the Greater Los Angeles area of Southern California in four multiethnic communities (Hispanic/Latino, African American, Korean/Asian, and non-Hispanic White). A 35-minute interview assessed the employee's tobacco product use, perceptions of vaping research, and experience advising customers to quit cigarette smoking.

Results

Among 121 vape shop employees surveyed, 106 (88%) reported that they provided smoking cessation advice or counseling to customers. Nearly half (45%) reported having no vaping-related research knowledge, while 30% were aware of provaping studies only. Approximately 85% of employees had quit cigarettes by switching to e-cigarettes instead, whereas 15% were dual users. Only 49% believed that vaping products contribute to nicotine addiction among youth. Those who provided advice on quitting cigarette smoking reported significantly lower knowledge of e-cigarette research than those who did not provide advice (p < .01).

Conclusions

Most vape shop employees provide advice to customers who desire to quit cigarette smoking and initiate electronic cigarette use. However, they report a low level of awareness about e-cigarette research. Future research is warranted to examine the specifics of advice provided by vape shop employees. Training programs for vape shop employees and educational campaigns about evidence-based scientific findings on vaping may be beneficial.

Implications

Almost nine out of 10 surveyed vape shop employees offered cigarette smoking cessation advice to their customers, while almost half of the retailers report not being aware of any vaping-related research studies. Providing employees with training on evidence-based cessation advice could help protect customers. Also, training programs for vape shop employees and educational campaigns about the risk of nicotine addiction could potentially increase their motivation to avoid sales to minors and to warn adults about nicotine addiction.

The novel 2019 Coronavirus Disease (COVID-19) pandemic has led to the closing of all but essential businesses in California. However, several nonessential businesses have remained open in Southern California despite the mandated "stay at home" order issued by the governor. As part of an ongoing vape shop project involving 88 participating shops, this study investigated the number of vape shops that remained open amidst the coronavirus outbreak and related mandates. Examination of shop social media websites and telephone calls to shops revealed that 61.4% (n = 54) have remained open, particularly within Korean/Asian and Hispanic/Latino ethnic locations (32 of the 54 shops). Importantly, walk-in service was much higher within Hispanic/Latino locations compared to African American, Korean/Asian, or non-Hispanic White neighborhoods (p = 0.03). It is not known if shops that stayed open were in direct violation of the order, didn't know all the details of the order, or found a loophole in the order and believed that they were an essential business. Better communication between the vape shop industry and public health officials during this pandemic is needed.

Objective

The 2016 FDA's "Deeming Rule" prohibited free samples of vaping products. The purpose of this study was to investigate compliance with or adaptation to this newly established FDA policy.

Methods

Vape shops were recruited in Southern California between November 2017 and December 2018. Data collectors interviewed 121 vape shop employees who responded to questions pertaining to the sampling protocol at their shop. Nicotine levels used for sampling were also assessed for consideration of future policy adoption.

Results

Only 7.4% of shops were non-compliant to federal sampling rules. The remaining shops either: 1) charged a fee for samples (58.7%); 2) deducted the fee from the final purchase price (5.8%); or 3) eliminated product sampling (28.1%). Of the shops that charged for sampling (including membership fees), 94.4% initiated a minimal cost protocol (≤$1) for sampling. Half (50.0%) the shops that allowed sampling offered nicotine-containing samples.

Conclusion

There was high compliance (92.6%) to the change in policy among vape shops. However, minimal modification of sampling protocol was observed due in part to the lack of specificity on parameters of compliance, which lessened the potential impact of the policy. To further protect consumers, policymakers must develop unambiguous and comprehensive policies to achieve intended results and true compliance. At minimum, future tobacco product sampling policies should consider standardized pricing; alternatively, total elimination of tobacco product sampling is suggested.

Introduction

Past studies have documented disparities in regulation compliance among tobacco retailers with respect to ethnic diversity in neighbourhoods. This study investigated the association between compliance with the Food and Drug Administration (FDA) and California state rules and neighbourhood ethnic composition of a vape shop location.

Methods

We recruited 122 vape shops located in 'ethnic enclave' neighbourhoods in Southern California. Trained teams of data collectors visited each of the consented vape shops and coded items in the shops that were visible and on display. Location data for the percentages of ethnic composition for a given city were obtained from the U.S. Census Bureau, American FactFinder. Multilevel logistic regression models examined the relationship between the city-level neighbourhood ethnic composition and vape shop rule violation status: not displaying Ask4ID sign and offering free samples.

Results

Vape shops located in neighbourhoods/communities with more white residents were significantly less likely to not display Ask4ID sign (p=0.03) and less likely to offer free sampling (p=0.009), controlling for other neighbourhood ethnic characteristics.

Discussion

Greater enforcement for proper signage display is needed for vape shops located in racial/ethnic minority locations to ensure that minors are discouraged from purchasing e-products.

Objectives

Vape shops have proliferated in the United States (US) in recent years. As of May 2016, the US Food and Drug Administration (FDA) asserted its authority to regulate electronic nicotine delivery systems. It is critical to understand how these polices have affected the vape shop industry, as the rise and fall of vape shop proliferation has the potential for influencing public health.

Methods

In this longitudinal study, we examined factors associated with vape shop (N = 77) closure over a 2-1/2-year period in southern California. We assessed predictors of vape shops going out of business using a multivariate logistic regression model.

Results

Among 77 vape shops assessed at baseline, 44.2% closed over a 2-1/2-year period. The absence of a "bar type" physical environment (OR = 2.64, 95% CI = 1.12-6.20), poorer shop accessibility (OR = 7.11, 95% CI = 1.17-43.24), fewer reports of qualified personnel (OR = 2.28, 95% CI = 1.12-4.64), less average time spent in shop by customers (OR = 4.8, 95% CI = 1.18-19.60), a narrower e-liquid flavor selection (OR = 6.55, 95% CI = 1.56-27.49), and less vape device diversity (OR = 2.36, 95% C = 1.13-4.91) predicted vape shop closure.

Conclusions

The rise and subsequent decline in vape shops could potentially affect public health. However, there needs to be more research on their association with public health..

The overall aim of this study is to examine vape shop business operations during COVID-19 among a cohort of 88 vape shops in the Greater Los Angeles area in Southern California, located in ethnically diverse communities. A total of six web- and/or phone-based assessments were conducted over a 12-week period (April 1, 2020-June 10, 2020), extending from the mandated closure of nonessential businesses (Stage 1; Assessments 1-3) to the reopening of nonessential sectors (Stage 2; Assessments 4-6), to evaluate business operations (open and closure statuses). The proportion of vape shops found to be noncompliant with the Governor's executive order (i.e., open) during Stage 1 gradually increased from 54 (61.4%) at Assessment 1 (week of April 1, 2020) to 58 (65.9%) at Assessment 3 (week of April 29, 2020). Moreover, vape shops located in Hispanic/Latino and Korean/Asian communities (vs. those in non-Hispanic White and African American communities) were more likely to stay open both during and after the shutdown at Assessments 1 and 6. More specifically, vape shops located in Hispanic/Latino communities were significantly more likely to offer walk-in service during Assessment 1 (during the shutdown), and vape shops in Hispanic/Latino and Korean/Asian were significantly more likely to offer walk-in service during Assessment 6 (after the re-opening). This study demonstrates high rates of noncompliance with shutdown orders among vape shops located in ethnic communities, thus suggesting higher contextual risk factors of COVID-19 exposure among certain ethnic communities.

Objectives

In February 2020, the US Food and Drug Administration issued a guidance restricting the sales and distribution of cartridge-based e-cigarettes with flavours other than tobacco and menthol. Disposable devices were exempt from this guidance. This study examined the prevalence of disposable pod use and flavour preference compared with refillable pod and other e-cigarette users among vape shop customers.

Design

Cross-sectional study.

Setting

In July 2019-March 2020, trained data collectors visited 44 vape shops in California with permission to recruit customers from shop owners.

Participants

Intercept interviews with 276 customers were conducted.

Outcomes and procedures

Customers were grouped based on self-reported device type used most often (disposable pod, refillable pod and other e-cigarettes). Groups were compared on self-reported demographics, flavours preferred, daily e-cigarette use, preferred nicotine concentration levels and cigarette use.

Results

Of the 276 customers surveyed, 11.2% used disposable pods in the past 30 days. Among disposable pod users, fruit/candy (80.7%), mint (77.4%) and menthol (67.7%) were common preferred flavours, while tobacco flavours were less commonly preferred (19.4%). When compared with refillable pod and other non-pod e-cigarette device users, disposable pod users were younger, used higher nicotine concentration levels, were more likely to prefer mint and menthol flavours and use e-cigarettes as their first product, while less likely to ever use cigarettes and use e-cigarettes daily.

Discussion

Despite using higher nicotine levels and preferred menthol/mint flavours more often than users of other devices, disposable pod users reported lower prevalence of lifetime smoking and daily vaping and were younger. Given the current findings, regulations addressing non-tobacco flavours and nicotine concentration in disposable pod devices merit consideration in efforts to reduce vaping in younger adult never smokers.
